Introduction
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
Features and Benefits
SPEEDLAN 9200 Features
The SPEEDLAN 9000 series introduces the second generation of wireless routers. The
SPEEDLAN 9200 offers the following new features:
1-2
•
New Wireless Mode parameters (e.g., 5GHz OFDM, 2.4GHz DSSS or
2.4GHz OFDM), Preamble, Tx power and SSID). For more information, see
Configuring the Radio Parameters, page 3-38.
•
Double the transmission rate with turbo mode, up to 108Mb/s for 5GHz
OFDM. For more information, see Configuring the Radio Parameters,
page 3-38.
•
You can allow a mesh node in a 9200 network to communicate with a
SPEEDMesh-enabled client in adhoc mode. For more information, see
Enabling/Disabling the SPEEDMesh-Enabled Client, page 4-5.
•
Provide network security between SPEEDMesh-enabled clients (PDAs and
laptops) and SPEEDLAN 9200 routers via WEP. In a SPEEDLAN 9200 network,
you can authenticate a SPEEDMesh-enabled client with a standard security
mechanism called Wired Equivalent Privacy (WEP). WEP encrypts data that is
transmitted over the wireless LAN. WEP protects the wireless link between
clients and access points. Network administrators can control access via
standard 802.11 client using WEP. For more information, see B. Enabling
WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200,
page 4-4.
•
Provide DHCP relay: This first release of the SPEEDLAN 9200 shall use the
DHCP relay function to forward DHCP requests from non-SPEEDLAN wireless
clients to one or more DHCP servers. Those DHCP servers maybe suitably
configured SPEEDLAN 9200 routers (in which they won’t relay), or they may be
dedicated servers, reachable through the Ethernet interfaces of one or more of
the SPEEDLAN 9200 routers. To configure DHCP relay, see Configuring
DHCP Relay, page 3-50.
•
Support for DC input sources: Devices that lack AC power will require DC-toDC supply.
•
At this time, star mode (i.e., base, point-to-point and CPE)
is not available. Only mesh mode is available.
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
The SPEEDLAN 9200 offers the network manager unsurpassed flexibility in meeting the
challenges of designing, building and managing today's wireless broadband networks.
In a mesh topology, the SPEEDLAN 9200 routes traffic around physical limitations,
eliminating the line-of-sight (LOS) issue present in star topology-only networks. Each
mesh router will communicate with other mesh routers in a radius of up to 2 miles
depending upon the model and signaling rate selected. This creates a multi-hop IP
routed cell: self-healing, load balancing, and scalable network. By removing LOS
issues caused by large buildings, hills, and other obstructions, service providers can
reduce network deployment costs while maximizing their broadband wireless
investment and reach new markets that could otherwise not be served.
For more information about mesh, see SPEEDLAN 9200 Mesh Protocol -- How It Works
in Mesh Cells, page 1-6.
ISP Functionality
The SPEEDLAN 9200 products are tailored to fit the needs of Internet Service Providers
and Broadband Telecommunications Providers. Two features particularly useful to
Internet Service providers are Network Address Translation (NAT) and Dynamic Host
Configuration Protocol (DHCP). NAT helps to ensure network security and allows an
entire company to share a single global IP address for communication on the Internet.
This enables companies to communicate with other devices on the Internet. DHCP
servers provide efficient use of IP addresses by assigning them dynamically or statically
to the wireless router location. DHCP allows network administrators to dynamically
assign IP addresses for the period of time needed to connect to the Internet or network.
IP Router Functionality
The SPEEDLAN 9200 is a highly configurable wireless IP router which supports mesh
topologies. In addition to being configurable via a standard web browser, the
SPEEDLAN 9200 also contains a firewall to control incoming and outgoing traffic,
preventing unauthorized access.

Configuration Management
The SPEEDLAN 9200 Configurator is a web-based management tool that allows a
network manager to configure routers. For more information, see General Functions of
the Configurator, page 3-1.
SPEEDManage
The SPEEDManage suite offers network management tools to help you troubleshoot
and resolve network issues to keep your network running. Packaged in SPEEDManage
are SPEEDView®, SPEEDSignal® and IP Recover:
•
SPEEDView® is a flexible Windows®-based management tool that allows you
to quickly isolate and resolve network problems. SPEEDView gives you an "ata-glance" view of your network, presenting you all of the nodes on the
network. Network managers can monitor local and remote SPEEDLAN 9200
nodes from a central location, or from any location on the network.
SPEEDView also allows you to troubleshoot network bugs and non-existent
physical connections. You can also perform bandwidth and diagnostic tests.
•
SPEEDSignal® allows you to communicate with SPEEDLAN 9200 routers via
their wireless or wired interface. This software makes it easier for installers to
troubleshoot antenna alignment problems in the field.
•
IP Recover is an application that allows you to temporarily change the IP
address on the router if you forgot it. You can also locate the configured IP
address of a router’s Ethernet interface.
For information about SPEEDMange, see the SPEEDManage User Guide.

Part # 34357-MNL Rev.03
•
Hardware AES 128-bit encryption for security between SPEEDLAN 9200
routers.
•
You can recover lost IP addresses. (Use IP Recover in SPEEDManage.)
Note: Advanced Encryption Standard was adopted by the National Institute of
Standards and Technology in October of 2000. AES presents a new level in computer
networking security, especially important in wireless communications because wireless
circuits are easier to tap than their hard-wired counterparts.
AES is more difficult to crack than its predecessor Data Encryption Standard. These
routers use an AES 128-bit encryption key.
Encryption Note! A Web browser must support 128 bit encryption in order to be
used with the Configurator. For more information about AES, visit http://
www.nist.gov. This User Guide explains how encryption works with 9200 products in
A. Enabling Encryption Between SPEEDLAN 9200 Routers, page 4-4 and B. Enabling
WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200, page 4-4.
Priority Queuing
Despite having two physical interfaces, a SPEEDLAN 9200 router can experience
congestion. That is because the interfaces' bit rates are not matched. Specifically,
packets can ingress (enter) the Ethernet interface faster than they can egress (exit) the
wireless interface. If this occurs briefly, it is called short-term congestion, which can
cause increased packet delay and/or jitter. If congestion lasts too long, it can cause
packet discard ("loss"). Long-term congestion in a SPEEDLAN 9200 will typically only
occur when it receives excessive unthrottled UDP traffic at its Ethernet interface. TCP
traffic will self-throttle, typically experiencing only short-term congestion, if any.
A SPEEDLAN 9200 mitigates short-term congestion by providing priority egress
queuing at its wireless interfaces. With priority queuing, packets may be transmitted in a
different order than they were received. This allows favoring network management,
VoIP and SCADA, over SMTP, ftp, and NNTP (for example).
How does Priority Queuing work? The packets are prioritized into a hierarchy of
queues, based on class of traffic. The highest priority queue packets are serviced first.
When the highest queue is emptied, the next lower queue is serviced. The SPEEDLAN
9200 has four levels of priority queues.
1-5
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
Queue 1 (the highest queue serviced) contains "management" traffic (i.e., RIP, Mesh,
K2, SNMP). Queue 2, the next lower queue serviced, contains "real-time" traffic (i.e.,
VOIP, Video, SCADA). Queue 3, the next lower queue serviced, contains "non-real
time interactive" traffic (i.e., HTTP, SSH and Telnet). Queue 4 (the lowest level queue
serviced) contains all traffic that doesn't fit into one of the first three queues.
There are no matching or requirements for this queue; it is simply the default queue if
the packet doesn't qualify for one of the first three queues.
SNMP
The SPEEDLAN 9200 contains a Simple Network Management Protocol (SNMP) Agent
that provides a remote Network Management System (NMS) with read-only ("get")
access to certain configuration and status parameters. For more information, see
SNMP, see SNMP, page 3-26.
Equipment and Hardware
For information about equipment and hardware, see SPEEDLAN 9200 Hardware,
page 2-1.

Cells

SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
SPEEDLAN 9200 routers provide the unique ability to "self-heal" the wireless network as
the topography changes over time, thereby increasing the overall stability and
performance of the network while allowing traffic to reach buildings blocked by
obstructions of line-of-sight.
What is happening in Figure 1-1 on page 1-6?
•
You will notice negative numbers next to the routers, or referred to as nodes
on the network diagram. These numbers represent the receive signal strength
(expressed as dBm) for the links in the network diagram.
•
The black dots in a mesh network diagram indicate a trace route, which maps
out the current data flow between the selected pair of nodes. A user would
select the trace feature to view the data flow between a node pair (for mesh
networks only).
This illustration also shows that every router in the mesh cell can be heard by
every other router in the cell, except for the blocked link indicating that there is
no signal between those two nodes.
SPEEDView allows you to block traffic over any link in the cell. When you block
a connection, the node pair will not be able to communicate. The advantage
of blocking a connection is verifying that the path can be re-routed for successful connectivity. (This is done using the "Block" feature in SPEEDView. The
broken [or disconnected] link will appear as a red line. This link also appears
when there is no signal between two nodes.)
•
SPEEDView can also be used to perform bandwidth, link and ping tests.
Routing Around Obstacles

SPEEDLAN 9200 User Guide
Explaining this scenario on the simplest level (using the Mesh protocol as shown in
Figure 1-2 on page 1-7). A can route a packet to B, despite the tree obstruction (block
of trees) within the path. How does this procedure work?
A has line-of-sight to C but not to B.
C has line-of-sight to A and to B.
The most efficient path in this case is to hop from A to C to B.
Note: No manual programming is required because A automatically detects its
neighboring router (in this case C, and B and detect a clear path to C). Therefore, the
packet is successfully routed around the obstacle between B and A.
This process creates a more scalable, flexible, and extended wireless network (as shown
in Document Changes/Corrections, page 1-11).
SPEEDLAN’s Mesh Cell Architecture
Separate multi-user and residential models (SPEEDLAN 9201 for business and
residential use, as well as the SPEEDLAN 9204 for residential use) are specifically
designed to meet the connectivity demands for everyone from single users to large
corporations. SPEEDLAN 9201 and SPEEDLAN 9204 are mesh units. These models will
communicate with every other mesh router within an unobstructed radius of 1/2 mile
for SPEEDLAN 9201 and 1/4 mile for SPEEDLAN 9204.

SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
SPEEDLAN 9200 Mesh Core Components
SPEEDLAN 9200 Mesh protocol includes three central components which are neighbor
discovery, topology updates, and routing.
Neighbor Discovery
Neighbor discovery occurs when each router sends a broadcast "hello" message to
detect those routers to which it has line-of-sight. The "hello" sender acknowledges those
replies, whereupon the sender and the neighboring router add each other to their
respective active neighbor lists. Neighbor discovery protocol messages are sent by each
router on startup and periodically thereafter. The periodic messages are required to
determine when a former neighbor can no longer be reached, whereupon it is removed
from the active neighbor list. Neighbor discovery messages are relatively short and are
sent infrequently enough that they don't constitute significant overhead.
Topology Updates
When a router adds or deletes a neighbor to or from its active neighbor list, it
propagates that information to the rest of the routers in the wireless mesh LAN. Unlike
classic wired routing protocols, topology update notifications are not flooded. Instead
they are sent via a spanning tree, such that each router receives only one notification of
a particular event. (A brief explanation of the spanning tree algorithm is explained in
the note below.) This approach also conserves bandwidth for use in forwarding user
traffic. Since each router knows the topology of the entire wireless LAN, it can
determine the shortest path to each peer router in the wireless LAN.
Note: In short, the spanning tree algorithm enables units to dynamically locate a
subset of the topology that is loop-free. The spanning tree algorithm determines the
best path a unit can use to send a message.

Routing
Routing is simply the act of forwarding a received Internet Protocol (IP) datagram (a
block of data) toward its destination. The router compares the destination IP address to
entries in its routing table. If the destination is a wireless neighbor or a node connected
to the router's wired LAN, the router sends the datagram directly to the destination.
Otherwise, it sends the datagram to another router, which must be on the wired LAN or
be a wireless neighbor.
In wired broadcast LANs, all routers on the LAN can hear each other. Therefore, a
datagram only passes through a router when it is moving from one LAN to another LAN
along the path to its destination. In a mesh wireless LAN, not all routers can hear each
other. Therefore, a router within a wireless LAN may forward a datagram to a neighbor
router within the same wireless LAN, in order to send the datagram toward its
destination. For each datagram, the routing algorithm minimizes the number of routerto-router hops within the wireless LAN, thereby also conserving bandwidth for other
user traffic.
Why SPEEDLAN Outperforms Other Routing Equipment
The SPEEDLAN 9200 outperforms other routers because the SPEEDLAN 9200 routing
table broadcasts only the information that changed, such as when new routes are
added or old routes are removed from the network. This information is sent to the
router's immediate neighbors along the most efficient path to the end destination. This
process helps conserve bandwidth. If an existing path is modified in some way, by the
addition or deletion of a router, a SPEEDLAN 9200 using the Mesh protocol can
monitor its routing table to decide if a secondary path should be taken. One could call
this a "self-healing" network, which means it finds a secondary route through the
network without manually reprogramming the routers.

2-4
•
SPEEDLAN 9201: A router used in a non-line-of-sight pico cell (using the
Mesh protocol). This router contains an integrated 8 dBi, omni antenna (for
2.4 GHz only) which is directly attached on the top. You do not need an
additional external antenna. The parameters are configured with the Mesh
protocol in the SPEEDLAN 9200 Configurator. This type of self-healing Mesh
topology process helps you reach buildings that do not have a clear line-ofsight back to a base station without the possibility of interference from hidden
transmitters. For more information on this topic, see SPEEDLAN 9200 Mesh
Protocol -- How It Works in Mesh Cells, page 1-6.
•
SPEEDLAN 9202: This model can be configured as Customer Premise
Equipment (CPE) at one end of the point-to-point or point-to-multipoint link. It
can be used with a 2.4GHz or 5GHz external antenna.
•
SPEEDLAN 9203: This model is pre-configured as a base station but can be
reconfigured to function as a CPE router or as one end of a point-to-point or
point-to-multipoint link. It can be used with a 2.4GHz or 5GHz external
antenna.
•
SPEEDLAN 9204: This model provides the same functionality as a SPEEDLAN
9201, but it uses an integrated 5 dBi omni (for 2.4GHz only). The SPEEDLAN
9204 is intended for more densely populated cells.
•
SPEEDLAN 9205: This is similar to the SPEEDLAN 9202, but can be used only
in 2.4GHz and 5GHz mesh-only applications.

To install your SPEEDLAN 9201/SPEEDLAN 9204, follow the steps below:
Step 1: Mounting the SPEEDLAN 9201/SPEEDLAN 9204
This router will have an omni directly attached. No additional steps are needed for this
step. Go to Step 2.
Step 2: Mounting the SPEEDLAN 9201/SPEEDLAN 9204 on the Pole
•
Pole Mount: Attach the router to the mounting pole using the two V-bolted
clamps and aluminum bracket, one on top of the router and the other on the
bottom of the router. Make sure you tighten the nuts for the clamps securely to
prevent shifting of the router after antenna alignment.
Step 3: Running the Cabling

inside the building.
Secure grounding wire by running this wire to a suitable "earth" ground and
fasten it securely in place. See the installation diagram following
these directions.
Install proper indoor ground plug into the junction box. Connect the outdoor
CAT5 Ethernet to the "radio" jack. Connect the LAN Ethernet cable to the "LAN"
jack of the junction box. Install the power supply DC connector to the junction
box. Plug the external power supply into the wall outlet.
(The VAC power outlet’s input voltage of this universal adapter can vary from
100 to 250 VAC.) Connect the DC output of the adapter to DC jack on the
indoor junction box.

Connect the wireless SPEEDLAN 9201/SPEEDLAN 9204 to the customer's
Ethernet LAN or PC by connecting the RJ-45 plug on a standard Ethernet
CAT5 cable to the RJ-45 port connector, marked as "LAN" on indoor junction
box. Connect the other end of the Ethernet CAT5 cable to your Ethernet hub,
switch or router.
Important Note: Waterproofing the External Connectors!
Make sure you waterproof all the connectors, as follows: Apply two layers of electrical
tape to the connector (covering three inches of cable past the connector), and leave
approximately 3 inches of cable exposed on either side of the connector. An alternative
is to begin at the lowest point, so the tape overlaps from bottom to top creating a
shingled effect. (This creates an effective barrier against runoff.) Apply this "shingle
effect" to each layer of the sealing process. Then, apply one layer of insulation putty
over the top of the electrical tape, and leave at least one inch of the cable jacket to
ensure a good seal. Do not stretch the putty, as this causes thinning and reduces the
effectiveness of a good seal. Finally, apply five layers of electrical tape over the
insulation putty and extend at least one (1) inch past the putty. This is the most
important step in a creating a watertight seal. Make sure that there are no wrinkles in
the tape, and the final wrap must be completed from bottom to top.

Installation Steps for the SPEEDLAN 9202/SPEEDLAN 9203/
SPEEDLAN 9205
Generally, these routers follow the same general installation steps. Some installation
instructions are specific to customers who purchased Installation Kits from P-Com. To
view a diagram of the installation listed below, see Figure 2-9 on page 2-21.
If you are having trouble and need a full site installation, contact P-Com for services
and fees.
Antenna Selection Tip: Use a high-gain omni or sectoral antenna for a base station
(SPEEDLAN 9203), and use a grid or directional antenna for a CPE or point-to-point
router (SPEEDLAN 9202). Use an external omni antenna for the SPEEDLAN 9205.
To install your router with an external antenna, do the following:
Step 1.Verifying Line-of-Sight
Before installing the antenna and router, make sure a clear line-of-sight exists between
the two points. Line-of-sight can be defined as each antenna clearly seeing the other
antenna, and seeing the remote locations when viewing from the central base location.
Be sure to look at the center of origin of the transmission (i.e., the middle of the
antenna). Repeat this procedure from the remote location. Any disruption of the signal
path due to trees, building, or any other obstructions may cause the link to function
incorrectly. Make sure at least 60 percent of the RF signal is unobstructed by any path
blockages.

Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
Note: For long distances, additional antenna height is often required to overcome
signal diffraction and to provide clear Radio LOS. For Radio LOS, a clear Fresnel
(Freh-nel) zone is required to minimize diffraction effects. The Fresnel zone is shaped
like an elongated football. The most clearance is required at the mid-point between the
two sites.
Beyond approximately 10 miles, the curvature of the earth can also become significant.
At these longer distances, visually sighting the remote site can be difficult or impossible
due to atmospheric haze. Terrain data (map or differential GPS) must be relied upon
for determining path clearance. Elevation data determined with these methods is above
Mean Sea Level; and does not account for curvature of the earth. Both the curvature of
the earth and the Fresnel clearance numbers can be combined to determine the
additional clearance required above any natural or man-made obstructions along the
path.
Obtaining this clearance can be accomplished by raising the antenna height at one or
both sites. If this is not practical, then consider relocating one or both sites to locations
with higher elevations. Another option is to add a third site to go over or around the
obstacle.
If you see any obstructions between two antennas, move one or both antennas to
another location.
Step 2. Mounting the Antenna
Follow the instructions below to mount the antenna.
On a side-building mount, position the bracket so there will be at least three
feet (one meter) above the roof line where the pole is attached. This enables
room for the antenna and reduces signal loss from building reflection.
Note:
It is not recommended to mount the antenna onto any unstable object.
Allow for as much space between the wall brackets as possible while
maintaining the appropriate antenna height. For extended poles, additional
wall brackets may be necessary.
Assemble the antenna and mount it to the pole using the included V-bolt
antenna mounting hardware. For a semi-parabolic grid type antenna, align
the grid to run parallel with the grid on the tip of the antenna horn.
2-16
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
A horizontal grid should be horizontal (or parallel to the ground). A vertical
grid should be perpendicular to the ground. Make sure all bolts and screws
are fastened tightly.
Horizontal-Oriented Grid
Vertical-Oriented
Grid
See also Tips for Antenna Alignment, page 2-5.
Figure 2-8: Grid antennas
Fasten the pole to the brackets. Position the antenna, point it in the
appropriate direction, and tighten the screws. Then, aim the antenna so it is
pointed toward the receiving antenna on the other building. The radio signal
radiates from the end of antenna like a wide-beamed flashlight. For optimal
performance, you may need to test your link using both horizontal and
vertical-oriented polarities. This configuration option varies with each location,
as well as RF signals that may be present in the area.
Step 3. Mounting the SPEEDLAN Router
Select one of two options below:
•
Option A: Pole Mount
On a pole mount, position the router 5 to 10 feet below the antenna. Then,
attach the router to the mounting pole using two included V-bolt clamps, one
on the top of the router and the other on the bottom. Make sure you tighten
the nuts for the clamps on the back of the pole mount.
2-17
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
OR
•
Option B: Wall or Concrete Mount
On a side building mount, position the router 5 to 10 feet below the antenna.
Then, attach the SPEEDLAN router to the wall or concrete by using the
concrete or wood mounting screws. Make sure it is securely mounted on the
wall.
Step 4. Running and Securing All Cable
The installation kit includes two cables with ready-made connectors to fit your particular
installation needs such as:
•
3’ RF cable
•
10' antenna cable (attaches to antenna one end and to lightning arrestor other
end)
•
Lightning arrestor (attaches to pigtail and to antenna cable)
Attach the 3’ RF cable to the RF port on the router.
Attach the 10' length of cable to the antenna. Next, attach the lightning
arrestor to the lower end of the antenna cable.
Attach the other end of lightning arrestor to 3’ RF cable.
Run the main length of the specialized outdoor Ethernet cable from the router
to the indoor junction box located inside the building.
Secure the cable (i.e., to the pole) with zip ties or cable clamps during this
procedure.
Note: When running the cable through walls or obstructions, make sure that there is
ample room for the connector to pass through the opening without being damaged.
Also, do not create extra pressure that would cause the cable to kink or be stretched or
cut (i.e., pulling cable through tight locations).
Create a proper weatherproofing seal on all outdoor connections by wrapping
it with electrical tape and sealing it with putty. This is the most crucial step of
the installation. If this procedure is not completed, long-term and complex
2-18
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
problems could occur. For more information on implementing this procedure,
see Weatherproofing Connectors, page 2-19.
Next, ground the lightning arrestor. For more information, see Grounding the
Lightning Arrestor, page 2-19. You can also ground the router case to the
ground, as shown in the installation diagrams in this chapter.
Step 5. Grounding the Lightning Arrestor
Mount the lightning arrestor to a solid surface.
Run the grounding wire from the lightning arrestor to a proper ground source
such as a grounding rod or roof ground wire. The lightning arrestor is NOT
waterproof. The next series of steps will show you how to effectively seal the
lightning arrestor and its cables.
Step 6. Weatherproofing Connectors
Seal the entire lightning arrestor with the black waterproof sealant insulation
putty that is included in the installation kit.
Apply two layers of electrical tape to the connector, and leave approximately 3
inches of cable exposed on either side of the connector. An alternative is to
begin at the lowest point, so the tape overlaps from the bottom, below the
bottom connector over the lightning arrestor and beyond the upper connector,
to top creating a shingled effect. (This creates an effective barrier against water
runoff). Apply this "shingle effect" to each layer of the sealing process.
Apply one layer of insulation putty over the top of the electrical tape, and leave
at least one inch of the cable jacket to ensure a good seal. Do not stretch the
putty, as this causes thinning and reduces the effectiveness of a good seal.
Apply five layers of electrical tape over the insulation putty and extend at least
one (1) inch past the putty. This is the most important step in creating a
watertight seal. Make sure that there are no wrinkles in the tape and the final
wrap must be completed from bottom to top.
Step 7. Connect the Router to Customer's Ethernet LAN
Connect the RJ-45 connector on a standard Ethernet CAT5 cable to the "LAN"
RJ-45 port on the indoor junction box.

Manual Initial Configuration of the SPEEDLAN 9200
Each SPEEDLAN 9200 is produced with a default configuration that renders it usable in
many applications. However, if you need to manually configure your SPEEDLAN 9200
router, follow the directions below.
Prerequisites
Configuration of the SPEEDLAN 9200 is done through the SPEEDLAN 9200
Configurator. In order to access the SPEEDLAN 9200 Configurator, you must have:
3-2
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
•
a client workstation (e.g., PC, Mac, Sun),
•
a compatible browser (Netscape Navigator 4+ or Internet Explorer 5+), and
•
a TCP/IP connection to the SPEEDLAN 9200.
A TCP/IP connection to the SPEEDLAN 9200 can be made through its wireless interface
or through its wired interface. If the default configuration creates a wireless LAN that is
compatible with the target inter-network, the network administrator can connect to the
individual SPEEDLAN 9200 router through that wireless LAN.
The following section assumes that a SPEEDLAN 9200 router is being configured via its
wired interface, possibly before it is installed at its intended physical location.
Connecting a SPEEDLAN 9200 and a Client PC
A connection between a SPEEDLAN 9200 and a client PC may be
established using either:
one crossover cable, or
two straight-through cables (also called patch cables) and a hub or a switch.
•
If you select option # 1, connect one end of the crossover cable to the client
PC and the other end to the junction box.

Figure 3-2: Crossover cable and pin out diagram
Note: The crossover cable actually crosses the transmit and receive pairs of wires so
that direct communications can take place between devices. Use a crossover cable
anytime you need to interconnect two computers or two devices in the same location
when a hub or a switch is either unavailable or not practical.
•
If you select option # 2, connect a straight-through cable from both the client
PC and the junction box to the hub or a switch.

SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
Upon power up, a SPEEDLAN 9200 router that is not configured attempts to obtain an
IP address for its Ethernet LAN interface from a DHCP server. This is done by
broadcasting a "DHCPDISCOVER" message on that interface. If a suitably configured
and reachable DHCP server replies within 30 seconds, the SPEEDLAN 9200 will use
the IP address, netmask, (etc.) that the DHCP server provides. Otherwise, the
unconfigured SPEEDLAN 9200 will adopt a private network IP address 192.168.69.1
and a /24 netmask (255.255.255.0).
If a DHCP server is not used, it is recommended that the SPEEDLAN 9200 router and
the client PC be on the same subnet. Otherwise, the ability to configure intervening
routers may be required.
If the SPEEDLAN 9200 that is not configured and the client PC are on the same LAN,
their IP address should be configured compatibly (same IP network and netmask). This
can be accomplished by either:
The client PC obtaining its IP address from the same DHCP server as the
SPEEDLAN 9200.
Statically set the client's PC IP address to 192.168.69.x (x is in the range of 2 254) and its netmask to /24 (255.255.255.0).
•
If you selected option #1 above, follow these general directions:
Open the Control Panel, and then double-click the Network and Dial-up
Connections icon. Go to TCP/IP Protocol Properties to select the Obtain
an IP address from a DHCP server option. Then, accept changes and close
this dialog box. Then, restart your computer.
•
If you selected option #2 above, follow these general directions:
Open the Control Panel, and then double-click the Network and Dial-up
Connections icon. Go to TCP/IP Protocol Properties to verify that your PC is
on the same network as the router 192.168.69.x (x is in the range of 2 254), and the subnet mask should be /24 (255.255.255.0). If you made
changes, accept the changes and close this dialog box. Then, restart your
computer.
Before continuing you should verify that the client PC has TCP/IP connectivity with the
SPEEDLAN 9200. The most common way to do this is to run 'ping' 192.168.69.1
(or the DHCP assigned address) at a command-line prompt. This ping command is
3-5
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
available in a Windows 9x DOS prompt, a Windows 2000 / NT / XP command
prompt, or any Unix console.
Configuring the SPEEDLAN 9200
Once your PC can access the SPEEDLAN 9200, you can open the client's browser and
enter the IP address of the SPEEDLAN 9200 router. If using DHCP and DNS, it may be
possible to refer to the SPEEDLAN 9200 router by its name.
Note: SPEEDView gives you a "management" view of the network. You will use the
SPEEDLAN 9200 Configurator (web browser) to configure the SPEEDLAN 9200
routers. If you want to configure a router in SPEEDView, just double-click any router
and it will open the SPEEDLAN 9200 Configurator. For more information about
SPEEDView, see the SPEEDManage User Guide.
Wireless Interface IP Address Assignment
If the wireless interface does not already have a statically configured IP address, it will
assume the 10.x.y.z/8 address, where x, y, and z are the decimal representations of the
least significant three octets of the IEEE 802 MAC address of the SPEEDLAN 9200’s
wireless interface. This method is used to ensure uniqueness. Because the last three
octets of the IP address are variable, a /8 netmask (255.0.0.0) is used in order for the
SPEEDLAN 9200s to communicate on this network.
Automating the Configuration of Multiple SPEEDLAN 9200s
In mesh mode, some of the configuration parameters for the SPEEDLAN 9200 are
common to all SPEEDLAN 9200s in the same network, for instance the channel and
signaling rate of the wireless interface.
Completing Configuration
Certain configuration parameters require a reboot after they have been changed.
Therefore, to ensure all changes have been activated, each SPEEDLAN 9200 should be
rebooted when its configuration is complete. Multiple SPEEDLAN 9200 routers can be
rebooted at the same time from either the SPEEDView application or the SPEEDLAN
3-6
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
9200 Configurator. To reboot the router in the SPEEDLAN 9200 Configurator, choose
Reboot from the System menu (see Reboot, page 3-31).
Adding Additional SPEEDLAN 9200s to the Wired Network
If you need to add an additional SPEEDLAN 9200 to the wired network, do the
following:
•
Connect the additional SPEEDLAN 9200 routers to a hub or switch on the
network and have DHCP assign IP addresses dynamically.
•
Connect additional SPEEDLAN 9200 routers to a hub or switch on the network
one at a time, changing the wired IP address of each router as it is added, to
an address other than 192.168.69.1 (to avoid duplicate IP addresses).
If you need help, contact your system administrator.

the SPEEDManage User Guide.
There are five classes of users on the SPEEDLAN 9200. The classes are as follows with
their default passwords:
•
Full Access (also known as a superuser): "wave_full" (this is also the only
access password for IP Recover in the SPEEDManage suite). Use this option
when changing passwords. You cannot change the password to an existing
password.
Note: "Full Access" does not show up in "Admin/Users" because the user will
not be able to change its permissions and it has write permission on
everything.
•
Wired Admin: "wave_wired_admin" (account for the private Ethernet network)
•
Wired Read: "wave_wired" (account for the private Ethernet network)
•
Wireless Admin: "wave_wireless_ad" (account for the wireless SPEEDLAN

Additional IP Addresses: Click this button to add an Alias IP. (You can
add an alias IP address to the Ethernet interface.) This allows you to assign
more than one IP address to an Ethernet interface. For more information, see
Alias IP, page 3-22.
•

Use DHCP: Select this option if you want to dynamically acquire an IP address
or DHCP from a DHCP server. The DHCP (Dynamic Host Configuration
3-21
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
Protocol) server assigns the IP address to each computer as the computer
connects to the network. If a computer moves to a new network, it must be
assigned a new IP address for that network. DHCP can be used to manage
these assignments automatically. Then, click Apply.
Optional: If you prefer, you can enter the client name of the host in the Client
Hostname text box (under "Use DHCP"). The limit of the Client Hostname is
16 characters. (See also Important Note about DHCP, page 3-45.)
•
Use this static address: Select this option if you want to statically assign an
IP address to the interface. For example: you may want to assign a "static" (permanent) address to a computer that will always be used as a server. This
enables other computers to connect to it. Static addressing is also beneficial to
users that need to maintain a "constant" connection to the Internet. Then, click
Apply.
Note: If you selected the "Use this static address" option, enter the Internet address
that you want to assign to the interface in the IP Address text box. You will also enter
the subnet/netmask for the IP address. Select the appropriate netmask in the Netmask
drop-down list.
After you change the Internet address for an Ethernet or directly connected
interface, you must restart the interface. Otherwise, the information will not be
updated. If you follow this step correctly, the next time you open the SPEEDLAN
9200 Configurator, these changes will be updated.
Alias IP
Note: Alias IP addresses can only be created for the Ethernet interface. They are not for
the wireless interface.
To add an Alias IP, do the following:
3-22
SPEEDLAN 9200 User Guide

Choose IP Addresses + Ethernet from the Network menu. Next, click the
Additional IP Addresses button on the IP Address Configuration (Ethernet)
page. The IP Addresses Configuration (for Ethernet) page will appear:
Figure 3-16: Adding an Additional IP Address (Alias IP)
Aliased addresses cannot be dynamically assigned from the DHCP server, so
you must manually type in the Alias IP in the text box, circled above. Verify the
netmask and click Add. Repeat this step for each Alias IP you add to the Ethernet interface.
Other elements on this window are described below:
•
# - (Address Number): The first address is the primary IP address on the
Ethernet interface. Addresses numbered 2 or higher are aliases.
•
IP Address: Lists the IP address of the primary or alias address.

Virtual Addresses
Choose Virtual Addresses from the IP Addresses submenu (under the Network
menu) to create a public IP address that can be mapped to a private IP address. Virtual
addresses are IP addresses (usually public) that the SPEEDLAN 9200 router can use in
addition to the IP addresses assigned to each of its network interfaces. Virtual
addresses are normally used to preserve public IP addresses when a limited number is
available. Previously, virtual addresses were implicitly created when referenced in a
3-23
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
NAT rule. Version 3.0 and higher requires explicit creation of a virtual address prior to
referencing it. Virtual addresses can be used to access the SPEEDLAN 9200 router for
configuration, or in NAT functions like Address Sharing, Internal Servers, and 1:1 NAT.
Virtual addresses are particularly useful when using 1:1 NAT, where you need more
than one public IP address. The virtual addresses do not need to belong to a network
assigned to one of the SPEEDLAN 9200's interfaces.
The existence of these addresses will be advertised with RIP, providing that the RIP filters
allow it. The Virtual Address page will appear when you choose the Virtual Addresses
feature.
The elements on this page are explained below:
•
IP Address: In this text box, enter the virtual address you want to add. Click
Add to add the new virtual address. (In the next figure, the user entered
"13.13.13.16" in the IP Address text box. Next, the user will click Add.)
Notes: You cannot apply an IP address from the Ethernet port’s subnet.
All virtual addresses have a netmask of /32 (255.255.255.255).
Existing Virtual Addresses
This list contains all defined virtual addresses.
•
To remove a virtual address, select it and click Delete Selected. (In the next
figure, if the user wants to remove virtual address "13.13.13.14". Then, the
user would select the check box next to it and click Delete Selected.)
•
To select all addresses, click All. To clear all selections, click None.
If an entry has "(In Use)" instead of a check box (as shown in the next figure to the right
of virtual address "13.13.13.13"), this means the virtual address is "in use" and cannot
be removed.

What is RIP-2 MD5 Authentication?
Both RIP-1 and RIP-2 are vulnerable to hostile messages and attacks. This is because
broadcast (RIPv1) or multicast (RIPv2) packets alone lack authentication. When RIP-2 is
used with an authentication algorithm, such as MD5, network security is increased
since the destination receiving the RIP packet knows that it was generated by a reliable
source (i.e., the actual sender of the packet).
RIP-2 MD5 authentication transmits the output of the authentication algorithm rather
than the RIP-2 authentication key. Therefore, the RIP-2 authentication key is never
transmitted over the network and cannot be heard by other routers. This means a router
can determine exactly who sent the message and not assume which router sent it.

parameter specifies the preamble setting in 2.4GHZ DSSS mode. There are
two types of preamble, short and long - referring to the length of the sync field.
The default setting is Short & Long. This setting is useful when you cannot
determine the field size of the data being sent. The system will sync itself for
both short and long. Users should select a Long preamble when there is a lot
of interference or noise on the network. (A short preamble is more likely to be
used in stable links with low noise levels.) The field size of a long preamble is
128 bits and a short preamble is only 56 bits.
Select the appropriate channel from the Channel drop-down list. This is the
specific band of frequencies to determine the data path between routers. All

Check the appropriate Signaling Rate check boxes. This setting refers to the
wireless signaling rate. The SPEEDLAN 9200 routers have different signaling
rates that can be used, depending on the wireless mode selected.
The signaling rate is intended to control the transmit rate, depending on the
quality of the link. If the link is getting better/worse, the signaling rate is automatically increased/decreased by one increment. By default, all the supported
signaling rates for the appropriate protocol are selected. An alternative is to
select a subset of the supported rates.

Max Tx Retries and Signaling Rate Fallback
This page includes two features: Max Tx Retries and Signaling Rate Fallback. On the
figure below, Max Tx Retries is circled in red and Signaling Rate Fallback is circled in
blue.
Figure 3-30: Tx Retries and Signaling Rate Fallback page
Note: To apply settings to other remote network nodes, select them and click Apply to
Selected Nodes. If you want to select all of the routers, click Select All.
The default for Max Tx Retries is 6.
Signaling Rate Fallback
During the retransmission of a unicast frame, the signaling rate can "fall back" in order
to increase the chance of reception. Signaling Rate Fallback can occur multiple times
for a single frame. Signaling Rate Fallback occurs from the current rate and will only
include those signaling rates selected on the Channel and Rates page. After ten
consecutive successful unicast frames, the current rate is restored to the highest
selected rate.
3-41
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
The Signaling Rate Fallback parameter allows you to control when the signaling rate
will drop, depending on the check box(es) you selected. That is, the check box(es)
labeled, "Allow signaling rate fallback on retry" (circled in blue on previous figure).
The following parameters (check boxes) govern at which point in the re-transmission
process the rate may be dropped:
•
1st retry: Will drop signaling rate on first retry.
•
2nd retry: Will drop signaling rate on second retry.
•
3rd retry: Will drop signaling rate on third retry.
•
4th retry: Will drop signaling rate on forth retry.
•
5th retry: Will drop signaling rate on fifth retry.
•
6th retry: Will drop signaling rate on sixth retry.
•
7th retry: Will drop signaling rate on seventh retry.
Here is one example.....
2.4GHz DSSS Example:
The network administrator has configured the allowable transmit signaling rates to be
11, 5.5, 2, and 1 Mb/s. (These values can be selected on the Channel and Rates page
under the Wireless menu.) In addition, the network administrator has selected 7 from
the Max Tx Retries drop-down list and set the signaling rate to "fall back" on the
second, fourth, and sixth retry attempts (as shown in blue on previous figure). When the
intended recipient does not acknowledge a transmitted unicast frame, it will be
retransmitted again (after a short timeout) at the current rate (e.g., 11 Mb/s). If this
attempt is also unsuccessful (e.g., the receiver did not acknowledge it), the signaling
rate will drop to 5.5 Mb/s and another attempt will be made. If after the third retry, the
transmission is still not successful, the signaling rate will drop to 2 Mb/s for the fourth
and fifth retry, and then to 1 Mb/s for the sixth and seventh retry (if needed).
The recipient sends acknowledgements at the same signaling rate at which it receives
frames. When a frame is successfully transmitted (acknowledgement received in the
case of unicast), the transmitter immediately proceeds to the next frame. The last
signaling rate used to transmit (other than acknowledgements) becomes the current
rate. After ten consecutive unicast frames, the current rate returns to the highest rate
3-42
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
selected, if it is not already at that signaling rate. Note that the receiver's signaling rate
is not affected (other than returning the acknowledgement at a possibly different rate).
Each transmitter's fallback schedule is independent of the signaling rate used by other
transmitters.
Max Tx Retries
P-Com recommends that you use this parameter to increase the throughput of your
wireless network. This parameter tells a network node the maximum number of times a
unicast frame can be retransmitted before it is discarded. (A unicast frame is one that is
transmitted to a single node in a network.) This allows a network manager to tune a
network for its particular topology and expected traffic characteristics. The network
topology, RF environment, number of nodes, throughput requirements, latency
requirements, and type of applications are all factors in choosing an appropriate value
for this parameter.
This parameter can be tuned on a per unit basis in order to optimize network
performance. Click Default to get the default value of 7. You can select a value
between 0 and 8 from the Max Tx Retries drop-down list.
Max Throughput (Regulating Bandwidth)
Max Throughput is useful to ISPs that want to regulate the maximum wireless bandwidth
provided from each customer.

DHCP Server Menu
The SPEEDLAN 9200 Configurator allows you to define a DHCP server on the Ethernet
interface. A DHCP server is configured with a table of Ethernet addresses, ranges of IP
addresses and maps that are assigned to client network devices asking for the network
settings. The DHCP server uses a "lease" to determine the length of time that a device
or interface can use the assigned IP address.
Servers that utilize DHCP resolve security issues, costly IP addressing services, and
compatibility problems. DHCP is a superset to BOOTP, which reduces the agony of
assigning static IP addresses, and also provides advanced configuration options.
How DHCP Assigns an IP Address
This section explains how a DHCP server assigns an address. If you are familiar with
this terminology, skip to Setting Up DHCP and DHCP Relay, page 3-45.
Figure 3-32: DHCP client and server
The client asks DHCP server for IP address and configuration if needed.
Note: The DHCP server allows IP addresses be assigned dynamically at the remote
building. Distributing these administrative functions to each remote building

significantly reduces the "administrative overhead" traffic that must travel back to the
service provider's headquarters. A DHCP server is configured with a table of IP
addresses that are assigned to client network devices asking for network settings. The
DHCP server uses a "lease" to determine the length of time that a device or interface
can use the assigned IP address.
The DHCP server assigns an available IP address to the client.
The client takes the IP address from DHCP server and requests for additional
configuration that is needed.
DHCP server confirms IP address and configuration.
The SPEEDLAN 9200 Configurator allows you to assign IP addresses via DHCP on the
interfaces.
Setting Up DHCP and DHCP Relay
These instructions will explain how to:
•

Important Note about DHCP
The DHCP Server serves IP addresses via the wireless interfaces in addition to the
Ethernet interface. The DHCP Server does not serve other nodes on the same wireless
cell.
For example, for Node A's DHCP server to serve IP addresses via its wireless interface,
at least one of the following must be true:
•
Another SPEEDLAN 9200 router on the same cell has DHCP Relay enabled,
and configured to use Node A's DHCP server.
•
Beyond the Ethernet of a SPEEDLAN 9200 router on the same cell, there is a
router (wired or wireless) whose DHCP Relay is enabled and configured to use
Node A's DHCP server.

Configuring DHCP Relay
DHCP Relay allows you to configure the SPEEDLAN 9200 to relay (forward) any DHCP
requests originating on the Ethernet interface to a remote DHCP server. This allows you
to use existing DHCP servers to assign IP addresses and other configuration parameters
for SPEEDLAN 9200 routers via their wireless interfaces. If this service is enabled and
no DHCP servers are listed, the SPEEDLAN 9200 will relay DHCP requests to the DHCP
server that the SPEEDLAN 9200 used to get its interface address. If this service is
enabled and the SPEEDLAN 9200 did not use DHCP to get an address for its interface,
there must be at least one DHCP server address listed for this feature to work.
To add DHCP Relay information, do the following:
Choose DHCP Relay from the DHCP menu. The following page will appear:
Figure 3-37: Configuring DHCP Relay

•
DHCP Servers: To enter a new DHCP server, enter the IP address and
click Add. This is the IP address of the DHCP server that is offering IP
addresses to its clients.
•
Delete: Click this button to remove information related to that DHCP
server address.
Once you have set up the SPEEDLAN 9200 router, configure the clients to
obtain an IP address from a DHCP server; do this on the PC and not on the
router! If the SPEEDLAN 9200 is the DHCP server, it will get the IP address
directly from it. If the DHCP server is located beyond the SPEEDLAN 9200
routers, the DHCP request will be forwarded to the DHCP server and then
returned to the correct client machine.
If a SPEEDLAN 9200 router is serving as a DHCP relay and it has alias IP addresses,
the IP network information that the SPEEDLAN 9200 relays to the DHCP server will
always be that of the primary Ethernet IP.
Viewing Log Messages
If the DHCP server is not working properly, you can view system log messages by
choosing DHCP Server. Then, choose Log Messages. The page will display log
messages for the DHCP server. Timestamps are also reported in client time.

Part # 34357-MNL Rev.03
Explanation of this feature
Despite having two physical interfaces, a SPEEDLAN 9200 router can experience
congestion. That is because the interfaces' bit rates are not matched. Specifically,
packets can ingress (enter) the Ethernet interface faster than they can egress (exit) the
wireless interface. If this occurs briefly, it is called short-term congestion, which can
cause increased packet delay and/or jitter. If congestion lasts too long, it can cause
packet discard ("loss"). Long-term congestion in a SPEEDLAN 9200 will typically only
occur when it receives excessive unthrottled UDP traffic at its Ethernet interface. TCP
traffic will self-throttle, typically experiencing only short-term congestion, if any.
A SPEEDLAN 9200 mitigates short-term congestion by providing priority egress
queuing at its wireless interfaces. With priority queuing, packets may be transmitted in a
different order than they were received. This allows favoring network management,
VoIP, and SCADA over SMTP, ftp, and NNTP (for example).
How does Priority Queuing work? The packets are prioritized into a hierarchy of
queues, based on class of traffic. The highest priority queue packets are serviced first.
When the highest queue is emptied, the next lower queue is serviced. The SPEEDLAN
9200 has four levels of priority queues. Queue 1 (the highest queue serviced) contains
"management" traffic (i.e., RIP, Mesh, K2, SNMP). Queue 2, the next lower queue
serviced, contains "real-time" traffic (i.e., VOIP, Video, SCADA). Queue 3, the next
lower queue serviced, contains "non-real time interactive" traffic (i.e., HTTP, SSH and
Telnet). Queue 4 (the lowest level queue serviced) contains all traffic that doesn't fit into
one of the first three queues.
Services
Network "Services" describe specific sessions between clients and servers, servers and
servers, or clients and clients on your network. Examples of servers that provide
services are web servers, FTP servers and email servers. Service definitions allow you to
forward public services inward to the internal (privately addressed) servers on your
network.

Three Features of NAT
NAT Background Info
Network Address Translation (NAT) occurs when there is a translation from one IP
address to another. There are several implementations of NAT - each with their own
purpose. One would choose the type of NAT that suits the task.
The SPEEDLAN 9200 offers 3 features that use NAT: Address Sharing, Internal Servers
and 1:1 NAT. Each is described below.
1. Address Sharing: This feature allows an administrator to share a public IP address
with privately addressed nodes. Typically, this is used to allow outbound connections to
the Internet from hosts who do not have IP addresses that can be reached from the
Internet. In implementing Address Sharing, requests to the Internet would be directed
3-56
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
to the SPEEDLAN 9200. The SPEEDLAN 9200 would then translate the source address
and port to one of its own, and then forward the request on to its destination. The
destination server would return the request to the SPEEDLAN 9200, which would
consult its NAT table, determine which host made the request, change the destination
address and port, and return the completed request. Similar to Internal Servers, this
process also creates the Network Address and Port Translations (NAPT). Address
sharing is possible when units need to act only as clients and do not need to respond to
requests. This is a useful feature if you have a limited number of public IP addresses.
You can use this feature to connect the whole LAN to the Internet using just one public
IP address. Here are some other benefits of address sharing:
•
reduce costs by using only one Internet account.
•
protect your information by hiding your workstations IP addresses.
•
restrict those users you want to access Internet services and resources.
The main Address Sharing page allows you to share the IP addresses assigned to the
SPEEDLAN 9200's network interfaces with all nodes connected to a different network
interface.
2. Internal Servers: This feature allows an administrator to make a service available
from an IP address, even though the owner of the IP address may not be actually
providing the service. Typically, this is used to allow access through a firewall to a
protected server. In implementing "Internal Servers," static NAT rules are established
that forward requests on a given port to a port on a server. For example, a client
request to port 80 on the SPEEDLAN 9200 would be forwarded to an internal web
server on port 80. The web server would then handle the request and return to the
client via the SPEEDLAN 9200 router. To the client, it would appear that the reply
came from the external address.
3. 1:1 NAT: This feature allows an administrator to statically map a public IP address
to the private IP address of one of the nodes on the network. This is useful when trying
to preserve a limited number of public IP addresses on the WAN network. Otherwise,
you may be forced to split a public network into two smaller networks and incur the
penalty of network and broadcast IP address for both of the new networks. All traffic,
regardless of protocol or port, is translated from the external address to the internal
address.

For example, a client request to any port on the "advertised" IP address would be
forwarded to the "internal" IP address of the node. The node would then handle the
request and return to the client the requested data. To the client, it would appear that
the reply came from the external address. This is also referred to as Static NAT.
Address Sharing
To share a public IP address with other computers, choose Address Sharing from the
Forwarding menu. The following page will appear:
Figure 3-42: Address Sharing page
The elements on this page are described below:
If you want to share an IP address assigned to the wireless or wired network interfaces,
select the address from the Address to Share list. (In the previous figure, the user
entered "12.1.90.141"). The "Share With Nodes" will automatically be selected (for the
StarNet interface in this example).
Note 1: Addressing Sharing works for connections originating from a host on the
"address to share" interface/network. Connections to actual IP addresses can still be
made from the outside network; those connections will not use the shared address. To
prevent this issue, make sure the firewall is enabled.

Note 2: If changes are made to "address sharing," connections that originated prior to
these changes may still use the previous configuration. The only way to ensure this does
not happen is to reboot the SPEEDLAN 9200 router.
If your WAN interface were the wireless network, you would share the wireless network
interface's IP address with nodes on the Ethernet network. For more options, click on
the Advanced link to the right of the "Add" button.

Firewall
The SPEEDLAN 9200 (via the SPEEDLAN 9200 Configurator) allows you to control
incoming and outgoing traffic.
A firewall prevents unauthorized access to a network. Utilizing the SPEEDLAN 9200
Configurator, SPEEDLAN 9200 routers can increase security and provide additional
support to the users of the network. In addition, it may help prevent dangerous packets
from intruding on a network that contains sensitive data. It does this by analyzing the
network traffic that is permitted or not permitted to enter the firewall based on
pre-established rules.
The firewall contains a checklist, and it filters traffic that enters and exits the firewall
based on the rules you set (e.g., allowing or denying certain source/destination
combinations). When traffic passes through the firewall, the firewall starts at the top of
its checklist and looks for the rule that matches its criteria. Traffic that meets the criteria
in the checklist will be permitted, and traffic that does not meet the criteria in the
checklist will be blocked. This feature allows you to restrict specific network packets
from entering or leaving your network.
Tips on Creating Rules for Your Firewall
Before you create a rule, make sure you:
•
Understand the purpose of the rule. For example, will this rule block all
IRC traffic from the LAN to the Internet? Will this rule allow a remote mail
server to send data at the same time over the Internet to an internal mail
server?
•
Do you want the firewall to allow or deny certain traffic? What type of
traffic? What type of IP protocol?
•
What is the direction of the traffic: from the Internet to the LAN or from the
LAN to the Internet?
•
What IP services will this rule affect?
•
Which nodes (or workstations) on the LAN will these rules affect? Make a
mental note of the IP address (those on the private and public LANs) that
these rules will affect.
•
Consider the security of the network. For example, once you enable this
rule, which areas of the network will become more vulnerable?

Note: When DHCP relay is enabled, it may appear as if DHCP requests get through
the firewall when they are not explicitly allowed. The reason for this is that DHCP
requests come in as link layer broadcasts (which are not filtered by the firewall) and
then the relay server unicasts from the SPEEDLAN 9200 router to the ultimate DHCP
server. These unicasts originate from the SPEEDLAN 9200 and thus are not considered
to be "forwarded" by the firewall. Turning off DHCP relay stops this behavior.

and click Delete Selected. Click All to select all firewall rules. Click None to clear all
selections. To change the Default Forwarding Rule, click the link that either says,
"Change to Allow" or "Change to Deny".
Note: Once you have finished configuring your firewall, reboot the SPEEDLAN 9200
router. This will terminate any undesired connections that may have existed prior to the
firewall configuration. You can verify if such undesired connections exist by opening the
IP Sessions page, which is last function under the Forwarding menu. For more
information, see IP Sessions, page 3-68.
Special Rules for Virtual Addresses
When you create a firewall rule that references a 1:1 NAT mapping or an internal
service using a virtual address, you must specify the internal address as the destination.
This is important to know because the virtual addresses have already been translated to
their defined internal addresses before the firewall examines the packet's destination.
Tutorial: What is happening in this firewall rule set?
As previously explained, a rule set tells the firewall what it can do. The rule set checklist
follows the top-down concept. The first row takes priority, and then follows the second
row's criteria, followed by the third, and so on.
Can you explain what is happening in the example below?

The explanation:
Rule 1 (FTP server): This rule will allow incoming traffic coming from the Star Net
interface to enter the firewall and go to the FTP server on 172.16.70.245.
Rule 2 (Web server): This rule will allow incoming traffic coming from the Star Net
interface to enter the firewall and go to the web server on 192.168.69.66.
Rule 3 (Mail server): This rule will allow incoming traffic from the Star Net interface to
enter the Internet mail server on the Ethernet interface.
Note about DHCP Rules 4 and 5: DHCP spans both rules 4 and 5. These rules allow
DHCP requests to a DHCP server from the Star Net interface to enter the firewall. The
Bootps service support server requests, and the Bootpc service provides client support
for DHCP.
Rule 4 (DHCP request): This rule allows DHCP requests to a server.
Rule 5 (DHCP reply): This rule allows replies to a client.
Rule 6 (AOL Instant Messenger: AIM): This rule will allow incoming traffic from the Star
Net interface to enter the firewall so clients can run AOL Instant Messenger.
Rule 7 (Anywhere): This rule will allow traffic coming from the Ethernet interface to go
through the firewall via the Star Net interface. The intention is to go anywhere on the
internet or the network).
Rule 8 (Deny incoming traffic): This rule will tell the firewall to deny other incoming
traffic. The firewall will not allow any incoming traffic to go through the firewall.

ARP Table
ARP is the abbreviation for Address Resolution Protocol, which maps an IP address to a
machine's hardware address. Network administrators use ARP to locate systems on the
LAN that are configured with incorrect IP addresses. This helps diagnose MAC
addresses that your router knows about.
To open the ARP table, choose ARP Table from the Diagnostics menu. The following
page will appear.
Figure 3-50: ARP page
The ARP statistics are defined below:
•
IP address: The IP address corresponding to the media-dependent 'physical'
MAC address.
•
HW Address: In a LAN environment each computer contains its own Medium
Access Control (MAC) address which is the embedded and unique hardware
number.
•
Interface: The interface on which this entry is effective.
ICMP Statistics
ICMP is the abbreviation for Internet Control Message Protocol. ICMP supplies
messages and error reports for packets that travel between host servers and gateways.
The ICMP stats can be used to diagnose a connectivity problem. If you are trying to
ping a router and you're not getting a response, you can check the "InMsgs" to see if the
ping arrived at the router and just could not get back. This might indicate that the
router has no route back to the originator.

AES is more difficult to crack than its predecessor Data Encryption Standard. SPEEDLAN
9200 routers use an AES 128-bit encryption key.
To enable AES between SPEEDLAN 9200 routers, do the following:
Choose Security from the Network menu. The Network Security
Configurations page will appear.
Enter the pass phrase in the Pass Phrase text box. The minimum amount of
characters is 8. The maximum number of characters is 32. Enter the pass
phrase again in the Confirm text box. Then, click the Change (Currently
Not Set) button to apply changes. You will receive a confirmation that the new
pass phrase has currently been set.
To enable encryption on a SPEEDLAN 9200, choose AES from the Encryption
Type drop-down list. "None" is selected by default. (If you select None,
encryption is disabled.) Click Apply to implement your settings.
B. Enabling WEP Security Between a SPEEDMesh-Enabled Client
and SPEEDLAN 9200
In a SPEEDLAN 9200 network, you can authenticate a SPEEDMesh-enabled client (PDA
or laptop) with a standard security called Wired Equivalent Privacy (WEP). WEP encrypts
data that is being transmitted over the wireless LAN. WEP protects the wireless links
between clients and SPEEDLAN 9200 routers.
Note: WEP is an encryption scheme used to protect wireless data communications.
WEP uses 64-bit, 128-bit or 152-bit key sizes to provide access control to wireless
network and encryption security for each data transmission. To decode a data
transmission, each point in a network must use an identical 64-bit, 128-bit or 152-bit
key.
To enable WEP security, do the following:

Type drop-down list. "None" is selected by default. (If you select None,
encryption is disabled.)
Choose Hexadecimal or ASCII Text from the Key Format drop-down list.
•
"Hexadecimal" is a Base-16 numbering system. The means the 16 sequential numbers are used as a base unit (i.e., "0-9" and "A-F").
•
In ASCII text, each numeric, alphabetic or special character is represented
with a 8-bit binary number (i.e., a consecution of eight 0s or 1s).
Select Key 1-3 from the Transmit Key drop-down list.
Select the length for the Transmit key by choosing either 64 Bits,128 Bits or
152 Bits from the Length drop-down list.
Note: 40-bit WEP and 64-bit WEP are two different names for the same encryption
method. This level of WEP encryption has been called "40-bit" because it uses a 40-bit
secret key along with a 24-bit initialization vector (i.e., 40 + 24 = 64). The same is
true for 104-128 bit and 128-152 bit WEP.
In the "Key1-3 text" boxes, enter the key value. For hexadecimal: a maximum
of "10 "characters for 64 bits, "26" characters for 128 bits and 32 characters
for 152 bits). For ASCII: a maximum of "5 characters for 64 bits, "13" characters for 128 bits and 16 characters for 152 bits.)
Click Apply to implement your changes.
Note: To enable the SPEEDMesh client, you must select the Enable Mobile Client
check box. For more information, see Enabling/Disabling the SPEEDMesh-Enabled
Client, page 4-5.
If WEP encryption is enabled, then:
•
All frames are WEP-encrypted, regardless of the packet’s destination
address in the case if AES encryption is disabled, and
•
All non-unicast frames are WEP-encrypted, regardless if AES is enabled or
disabled.
Enabling/Disabling the SPEEDMesh-Enabled Client

Receive (Rx) Threshold Parameter
From a single mesh unit connected to a mesh network, you can set the receive
threshold (given in dBm), for every mesh router in the network. The receive threshold
specifies the minimum acceptable receive level for a datagram (defined for signaling
rates, depending on the Wireless Mode you selected on the Wireless Configuration
page). Any datagrams received below these levels will be discarded. This will provide
better network stability for networks containing marginal links, since link state changes
(and the corresponding routing changes) will be avoided for marginal links which are
not capable of consistent communication.
By clicking the Defaults button, the values will go to their default values. If you enter a
value of 0 (zero), you are turning the receive threshold parameter off.

often used when a marginal signal exists between two nodes in a mesh network, such
that the network functions more reliably when no direct communication occurs between
the nodes. To completely block a link you must perform the same action on the remote
node.
Note: If you blocked a mesh router, the next time it is rebooted it will remain blocked.
If you want to unblock the router, make sure that the Blocked check box is not

Basics of IP Addressing
IP Addressing is important because it tells the network how to locate the computers or
network equipment connected to it. IP addresses are given so each computer or
equipment on the network has a unique routable address. IP addressing provides the
following information:
•
Provides communication between different platforms and diverse systems
•
Provides universal data transfer over large geographic distances
•
Has been "adopted" as a standard in the computer industry
What is an IP address?
An IP address is a unique 32-bit identifier that contains:
•
Four octets (e.g., decimal 192.0.2.56).
•
Two sections: the network address and the node address (also known as the
host address).
The following examples show the conversion of the same IP address into several
different formats:
•
Hexadecimal (82.39.1E.38)
•
Binary (10000010.00111001.00011110.00111000).
Internet Address Classes
Understanding this methodology is difficult; therefore, let's explain this in easier terms.
The first octet(s) defines the "class" of the address, which is the only method to tell the
size of the network (how big) and where the internet address belongs.
There are three main classes:
•
Class A: 35.0.0.0
•
Class B: 128.5.0.0
•
Class C: 192.0.2.0
-non-bolded text = Part of network address
-bolded text = Part of local address (node section)
5-2
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
This specification simplifies the way routers handle the messages (packets) and speed
up the forwarding process.
In fact, IP defines five classes:
•
•
•
Class A addresses uses 1 octet for the network portion and 3 octets for the
node (or host) section of the address. This provides up to 128 networks with
16.7 million nodes for each network.
•
First octet is assigned as network address
•
Remaining octets used for node addresses
•
Format: network, node, node, node
•
In IP address 49.22.102.70, "49" is network address and "22.102.70" is
the node address—all machines on this network have the "49" network
address assigned to them
•
Maximum of 16,777,216 node addresses
Class B addresses uses 2 octets for the network portion and 2 octets for the
node (or host) section of the address. This provides up to 16,384
networks with 64,534 nodes for each network.
•
First 2 octets are assigned as network address
•
Remaining octets used for node addresses
•
Format: network, network, node, node
•
In IP address 130.57.30.56, "130.57" is the network address, and
"30.56" is the node address
•
Maximum of 65,534 node addresses
Class C addresses use 3 octets for the network portion and 1 octet for the
node (or host) section of the address. This provides 16.7 million networks with
256 nodes for each network.
•
First three octets are assigned as network address
•
Remaining octet used for node address
•
Format: network, network, network, node
•
In IP address 192.0.2.102, "192.0.2" is the network address, and "102" is
the node address
•
Maximum of 28 or 254 node addresses
5-3
Part # 34357-MNL Rev.03
•
•
SPEEDLAN 9200 User Guide
Class D
•
Range is 224.0.0.0 to 239.255.255.255
•
Used for multicast packets (i.e., host sends out router discovery packets to
learn all of the routers on the network)
•
Netmask = /32
Class E
•
Range is 240.0.0.0 to 255.255.255.255
•
Reserved for future use
Note:
Class D & E should NOT be assigned to network assignment of IP
addresses. In addition, the first octet, 127, is reserved. In each network
definition, the first node number (i.e., "0") is used to define the network
(i.e., "255"). The last number is known as the broadcast address.
Note:
Public addresses can include a network address assigned from the network administrator or from the IP provider. Also, there is one network in
each class that is defined for private use, allowing the creation of
internal networks. These addresses are Class A: 10.0.0.0, Class
B:172.6.0.0, and Class C: 192.168.0.0.

Subnetting a Network
The increasing number of hosts and networks make large impractical address blocks
that are not smaller than 255. In order to keep the IP address block small, so routers
can manage them more efficiently, a smaller network definition is created. This is called
a subnet. Subnets are intended to:
•
Reduce network traffic
•
Optimize performance
•
Simplify management
•
Create more effective and efficient addresses for large geographic distances
Default Subnet masks
•
Class A: 255.0.0.0.
•
Class B: 255.255.0.0.
•
Class C: 255.255.255.0.
Note: Subnet mask is bolded and corresponds to the network portion of the IP address.
What is a Subnet?
A subnet allows you to create multiple networks within one Class A, B, or C network.
Each subnet contains a netmask that helps routers identify the subnet beginning and
size.
What is a Subnet Mask?
A subnet mask allows you to mask section(s) (depending on the class specified) of the
octets in the network address. Each octet used in the subnet mask is assigned to a data
link. The leftover octet(s) are assigned to the remaining nodes.
For more information on subnetting, see the example below and Diagram of Subnetting
a Network, page 5-6.
Example of Subnetting:
For example, a Class C network contains three masked octets (255.255.255). The last
octet (0) identifies nodes (i.e., computers).

If Router D is reading IP Addresses 192.0.2.1 (let's call this IP Address 1) and
192.0.2.64 (let's call this IP Address 2) on this Class C network, it would send IP
Address 1 to Subnet A and IP Address 2 to Subnet B. The remaining nodes in each
subnet (A through D) on this network can contain up to 254 pieces of network
equipment (computers, printers, fax machines, bridges or routers, etc.).

Still confused?
An easier method to explain this concept is to use the classic "mailing" analogy used in
IP addressing. Consider that this network, called Long Street, is four blocks long. There
are 254 houses on Long Street, and each block contains 64 houses. Houses 1 to 63
reside on Block A. Houses 64 to 127 reside on Block B. Houses 128 to 191 reside on
Block C. Houses 192 to 254 reside on Block D. Think of each block as a subnet. This
5-6
SPEEDLAN 9200 User Guide
Part # 34357-MNL Rev.03
means that Blocks A, B, C, and D are all part of Long Street, which is also known as the
network in this example. The mailman would organize the letters (or IP addresses for
network equipment) by creating four piles (one for each block, or subnet). As soon as
the mailman picks up pile A in his hand, he knows which block to turn on. This same
reasoning applies to piles B, C, and D as well. Router D knows exactly which subnet to
transfer (or turn) the packets to by reading its IP and subnet mask address. Note that
each subnet on this network is 255.255.255.192. Why is 192 the last octet in the
subnet mask and not 64? The last octet, 192, is the mask that allows 64 "houses" to
reside on the street.
Note:
If the network is managed by a Simple Network Management Protocol for
local or Internet access, each interface must contain a unique IP Address.
This is a benefit of static or dynamic addressing.
How does a network administrator assign an IP address?
IP addresses are supplied by the network administrator, the ISP, or hosting company.
The two types of IP addressing—manual (static) and automatic (dynamic) addressing—
are described below.
•
Manual (static) Addressing - Is ’Manually Configure’ option on
Interfaces Parameters page of SPEEDLAN 9200 Configuator
Each device connected to the Internet must have its own unique IP address.
Also, if a computer is being used as a server, you will assign it a permanent IP
address. This enables other computers to connect to it. Static addressing is
also beneficial to users that need to maintain a "constant" connection to the
Internet. This will enable users to easily access the IP address.
•
Automatic (dynamic) Addressing - Is ’Use DHCP’ option on Interface
Parameters page of the SPEEDLAN 9200 Configurator.
A DHCP (Dynamic Host Configuration Protocol) server assigns the IP address
to each computer as the computer connects to the network. If a computer
moves to a new network (i.e., great for temporary employees or mobile users),
it must be assigned a new IP address for that network. DHCP can be used to
manage these assignments automatically. DHCP is described in further detail
below.
5-7
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
What is DHCP?
Dynamic Host Configuration Protocol (DHCP) allows network administrators to assign
dynamic IP addresses for the period of time needed to connect to the Internet. Think of
DHCP as leasing an apartment. A prospective tenant may not need to live in an
apartment for two years, maybe just a year. Therefore, the tenant will only sign a oneyear lease agreement. For example, each time a computer is set up to connect to the
Internet, the network administrator uses DHCP to automatically assign the computer a
unique IP address. That computer will give up its IP address when it is no longer needed
(when the lease has ended) allowing new a computer (or a new tenant) on the same
network to use it. This benefits educational and corporate settings where users often log
on to different computers. In this case more IP addresses outnumber computers
because you can quickly reconfigure the network if needed from a centralized location.
Servers that utilize DHCP resolve security issues, costly IP addressing services, and
compatibility problems. DHCP is an alternative to BOOTP, which reduces the agony of
assigning static IP addresses and also provides advanced configuration options.
Note:
The figure on the next page may help you understand how DHCP assigns
and IP address.

The client asks DHCP server for IP address and configuration if needed.
The DHCP server assigns an available IP address to client.

configuration needed.

What is NAT?
Network Address Translation (NAT) is the conversion of an Internet Protocol address (IP
address) used within one network to a different IP address within another network. One
network is designated the inside network and the other is the outside network.
Network Address Translation (NAT) occurs when there is a translation among an
Internet Protocol (IP address) used within one network (designated as inside network) to
a different IP addresses within another network (designated as outside network).
Network Address Translators (NATs) allow companies to decrease the number of global
5-9
Part # 34357-MNL Rev.03
SPEEDLAN 9200 User Guide
IP addresses. This enables companies to communicate with other devices on the
Internet with a single global IP address (or more than one IP address).
For example, a company can provide its clients with one IP address, allowing access to
the company's firewall only. This IP address is not a "real" address on the company's
internal network, but it is successfully translated to the correct IP location through NAT
(i.e., NAT router). Therefore, the company controls access through firewalls and
provides multiple IP addresses to outside customers without excessive limited resources,
or "global" Internet IP protocols.
NAPT
What differentiates NAPT from NAT? NAPT (or Network Address Port Translation) not
only translates the IP address but also the transport layer port. Thus, if an inbound
packet was addressed to a web server port on 80, the NAPT device would translate and
pass to the packet to the private network's web server. Without port translation, the NAT
device has no means of knowing which host in the private network can pass packets to
other devices. For an example see, Diagram of Incoming NAT, page 5-12.

Basics of Routing
A router connects two or more networks or subnetworks together and decides which
direction it should send each packet. A router is typically a gateway (where one network
meets another). A router operates at the Network Layer of the OSI model. This means a
router sends information based on the packet's IP address instead of the Ethernet
(MAC) address (as in bridging).
Routing protocols use special metric algorithms when determining the best path for a
packet to travel. All of this information is stored in a routing table. Some of this
information includes hop count and destination information. The routing table also
stores when the receiver gets the packet and lets the sender know that is was received.
Note: For more information about routing, see www.whatis.com, http://
www.techweb.com/encyclopedia/, http://www.computeruser.com/resources/
dictionary/dictionary.html, or search for "basics of routing" on the World Wide Web.

Glossary for Standard Data Communications
Advanced Encryption Standard (AES)
Advanced Encryption Standard was adopted by the National Institute of Standards and Technology in
October of 2000. AES presents a new level in computer networking security, especially important in wireless
communications because wireless circuits are easier to tap than their hard-wired counterparts. AES is more
difficult to crack than its predecessor Data Encryption Standard. SPEEDLAN 9200 products use an AES
128-bit encryption key.
Address Resolution Protocol (ARP)
ARP is the abbreviation for Address Resolution Protocol, which maps an IP address to a machine's hardware
address. Network administrators use ARP to locate systems on the LAN that are configured with incorrect IP
addresses.

Digital Signal Processor (DSP)
A specialized computer chip designed to perform speedy and complex operations on digitized waveforms.
E1
An E1 is a full-duplex synchronous digital stream with a signaling rate of 2.048 Mb/s.
The electrical characteristics of the digital interface are defined in the recommendation
UIT-T G.703 (which by the way also defines it for a T1). Framing structure is defined in
ITU recommendations G.704 and G.732. Finally, the only countries in the world where E1
streams are not regularly used are in U A and Japan.
Elevation
1. Height above sea level. 2. The vertical angle in degrees between the ground and the direction the antenna
is pointed.
Encryption
The method of converting data into a form that cannot be understood by unauthorized people. Encryption is
very important when using wireless communication because wireless circuits are easier to tap into than
wired circuits. There is also strong encryption, which means ciphers are used to make uncoding the signal
almost impossible, unless you have the decryption keys.
ESD
Electro-Static Discharge happens when there is a transfer between objects at diverse voltages.
Ethernet
This is the most popular physical layer LAN technology in use today. Other LAN types include Token Ring,
Fast Ethernet, Fiber Distributed Data Interface (FDDI), Asynchronous Transfer Mode (ATM) and Local Talk.
Ethernet is popular because it strikes a good balance between speed, cost and ease of installation.
Ethernet Switch
This device helps expand the Ethernet network. LAN switches can link four, six, ten or more networks together,
and have two basic architectures. This switch “cuts through” and “stores and forwards” as well. This
technique takes more time to examine the entire packet, but it allows the switch to catch certain packet errors
and keep them from propagating through the network. A switch also operates between the DataLink and
Network Layer of the OSI model. It reads the MAC address and will either bridge it to the Physical Layer or
route to the Network Layer.

memory).
Forward Error Correction (FEC)
The ability of a receiving station to correct a transmission error. The transmitter sends redundant information
along with the original bits and the receiver uses this information to find and correct errors. This can increase
the throughput of a data link operation.
Framing
Dividing data for transmission into groups of bits, and adding a header and a check sequence to form a
frame.
Frequency
The number of complete cycles per second existing in a waveform. Note that frequency is measured in Hertz
(Hz).
Frequency Hopping (FH)
A type of spreading technique using a PN code to change the signal’s frequency between several
pre-assigned values (hopping). Although the signal itself looks like a narrow band signal at any given point in
time, it acts like a spread signal because of the frequency hopping.

SPEEDLAN 9200 User Guide
IP Address
This address tells the network how to locate the computers or network equipment connected to it. IP
addresses are given so each computer or equipment on the network contains a unique address. There are
two methods used when assigning an IP address:
• Automatic (dynamic) Addressing
A DHCP (Dynamic Host Configuration Protocol) server assigns the IP address to each computer as
the computer connects to the network. If a computer moves to a new network (i.e., great for
temporary employees or mobile users), it must be assigned a new IP address for that network.
DHCP can be used to manage these assignments automatically.
• Manual (static) Addressing
Each device connected to the Internet must have its own unique IP address. Also, if a computer is
being used as a server, you will assign it a permanent IP address. This enables other computers to
connect to it. Static addressing is also beneficial to users that need to maintain a "constant"
connection to the Internet. This will enable users to easily access the IP address.
ISM (Industrial, Scientific, and Medical Bands)
Ranges are 900 to 928 MHz; 2.4 to 2.4835 GHz; and 5.725 to 5.85 GHz. The FCC for unlicensed use

semicolons (i.e., 00:05:D5:12:AF:01).
MAN
This is a metropolitan network that enables computers, network equipment, other peripherals, and more than
one LAN to communicate within the city or nearby limits.

MDS (RIP2 MD5 Authentication)
When RIP2 is used with an authentication algorithm, such as MD5, network security is increased since the
destination receiving the RIP packet knows that it was generated by a reliable source (i.e., the actual sender
of the packet). RIP2-MD5 authentication transmits the output of the authentication algorithm rather than the
RIP2 authentication key. Therefore, the RIP2 authentication key is never transmitted over the network and
cannot be heard by other routers. This means a router can determine exactly who sent the message and not
assume which router sent it.
Mean Time Between Failure (MTBF)
This is defined by a specific set of calculations. The formula of the system longevity is based on the thermal,
electrical and environmental stresses on each component.
MHz (MegaHertz)
Millions of Hertz.

Multi-path fading
The condition in which the “true” signal from an antenna reflects off an object (usually the ground) and, as a
result, the reflected signal causes destructive interference at the receiving antenna. Multi-path fading affects
linearly polarized signals more than circularly polarized signals.
Network Address Translation (NAT)
NAT helps to ensure network security and allows an entire company to share a single global IP address for
communication on the Internet. This enables companies to communicate with other devices on the Internet.
Network
A set of connections that allow them to exchange data with each other, which enables multiple users to share
to communicate data through the accepted path(s). Two or more locations tied together with equipment and
communications channels.

Router
This device filters out network traffic by specific protocol rather than by packet address. This device operates
at the Network layer of the OSI model. Routers also divide networks logically instead of physically. An IP
router can divide a network into various subnets so that only traffic designated for particular IP addresses can
pass between segments. Network speed often increases due to this type of intelligent forwarding. Such
filtering takes more time than exercised in a switch or bridge, which only looks at the Ethernet address. In
more complex networks, overall efficiency is improved by using routers.
Rx (Receiver)
This is where the packet is going.

Subnet
This term allows you to create multiple networks within one Class A, B, or C network. Each data link (octet)
contains its own unique identifier also known as the subnet. Also, each node on the same data link must
belong on the same subnet as well.
Symbol Threshold
After a signal has been acquired, the acquisition algorithm in the spread-spectrum chip continues to run a
cross-correlation between the expected PN sequence and the received signal, but now uses the Symbol
Threshold for comparison. If the result of the cross-correlation drops below the Symbol Threshold, the signal
is considered to have been lost, and the algorithm begins trying to acquire the signal again.
