Antenna spacing requirements for user safety
It is important to keep the radio's antenna a safe distance from the user. To meet the requirements of FCC part
2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20
cm between the antenna and users. Greater distances are required for high-gain antennas. The FCC requires a
minimum distance of 1 mW *cm2 power density from the user (or 20 cm, whichever is greater).
If a specific application requires proximity of less than 20 cm, the application must be approved through the FCC
for compliance to part 2.1093.

User Manual Industrial Hotspot
1.1 About this manual
This manual covers the entire RadioLinx® RLX2 Industrial Hotspot™ series of
radio products. There are four products available in this product line:
Model Standards Maximum Output Power
IEEE 802.11a 24 dBm (250 mW)
IEEE 802.11b/g 24 dBm (250 mW)
IEEE 802.11a/b/g/n 17 dBm (50 mW)
IEEE 802.11a/b/g 23 dBm (200 mW)
Except for different operating frequencies and output power levels, these radios
all operate in a similar fashion. Different models operating on common
frequencies can communicate with each other. Furthermore, all RLX2 series
radios can communicate with ProSoft Technology’s legacy RLXIB series of
radios. Details on the specific differences between the RLX2 and RLXIB series
products can be found in the Compatibility with ProSoft RLXIB Series Radios
section on page 117.
When a feature is described in this manual that is unique to a specific RLX2
model, it will be highlighted like this:
This features applies to the RLX2-IHNF only
1.2 About the RadioLinx® RLX2 Industrial Hotspot™ products
1.2.1 General Features
The RadioLinx® 802.11 Industrial Hotspots™ are high-speed wireless Ethernet
radios, with Power Over Ethernet (PoE) and Serial Encapsulation. All radios

1.2.3 Antenna Ports
Each RLX2 series radio has three antenna connectors on the top, but not all
ports are active on all products as noted below:
These radios have a single active antenna port:
This radio has three active antenna ports:
This radio uses the right-side antenna port for transmit and receive. An
optional receive-only antenna can be attached to the left-side antenna
port for better performance. The middle antenna port is not used.
Models with inactive antenna ports are shipped with plastic caps on the inactive
ports. To avoid the possibility of attaching an antenna to an inactive port, ProSoft
recommends that users do not remove caps from inactive ports.

2 RLX2 Quick Setup
In This Chapter
Setup Master Radio ............................................................................... 20
Setup Repeater Radio ........................................................................... 26
Setup Client Radio ................................................................................ 28
This section describes how to setup RLX2 radios in a minimal configuration
before deploying them in the permanent installation. It will help verify the radios
are operational along with getting familiar with basic configuration procedures.
Note that the procedures described in this section assume the radios are in their
default configurations as shipped by ProSoft. If that is not the case, reset the
radios to factory defaults as described in section 6.7 before attempting these
procedures.
In any given network, there must be one radio acting as a Master, and the other
radios will be configured as Repeaters or Clients. Generally there is only one
Master radio per network.
Note: The RLX2 radios support the Rapid Spanning Tree Protocol (RSTP) which allows
configuration of multiple Master radios on a single network in “hot standby” mode for redundancy.
RSTP is described further in section 6.2.3
Because most wireless networks consist of one Master radio and multiple
Repeaters, all RLX2 radios are shipped from ProSoft pre-configured as
Repeaters. Hence our first task is to configure one radio as the network Master.
IMPORTANT: If a ProSoft Power adapter RL-PS007-2 (supplied with the RLX-IHBTK Bench Test
Kit) is not present, see section 8.5.1 for instructions on wiring the power connector.

User Manual Industrial Hotspot
2.1 Setup Master Radio
The first step is to select the radio to use as a Master. Typically all RLX2 radios
in a network will be the same model, although this is not necessary.
IMPORTANT: The only RLX2 radios that do not have any channels in common with each other are
the RLX2-IHA and RLX2-IHG. The RLX2-IHW and RLX2-IHNF radios can communicate with each
other and with the RLX2-IHA and RLX2-IHG radios.
If all the radios are present on the workbench, antennas are not needed for this
configuration exercise. Radios without antennas will have sufficient signal
strength to link over short distances, without radiating or receiving unnecessary
RF energy in the surrounding environment. The connections needed are on the
bottom of the radio:
1. Attach an Ethernet cable to the designated master RLX2 radio. Make sure this
network connection is on the same subnet as the PC running the IH Browser
configuration software.
Note: The Ethernet DATA LED should come on when data is sent or received from the radio. The
Ethernet SPEED LED indicates the speed of the Ethernet connection. The SPEED LED is off for
10 Base T, on for 100 Base T, and blinks about once every two seconds for 1000 Base T links.
2. Power up the radio. The power LED should illuminate with an amber color, then
go out for a few seconds during initialization, then finally come back on green.
This process will take 10 to 15 seconds. Once the power LED is green, the radio
has booted and is operational. Other LEDs may become active as well.
3. Take note of the MAC address of the RLX2 radio. This is printed on a label
attached to the front of the radio. The MAC address should be something like 00-
0D-8D-XX-YY-ZZ (e.g. 00-0D-8D-F0-5C-8E.) This number uniquely identifies the
radio on the network.

4. Run the IH Browser configuration software.
If the display is different than above, use the IH Browser toolbar controls to clear
and refresh the display:
The “erase” tool clears the display
The “search” tool rescans the network for RLX2 radios
If no radios appear in the list, see the section 5.6 on troubleshooting missing
radios.
5. In particular, note the line listing the MAC address of the RLX2 radio. If the radio
is on a network with a DHCP server, it will obtain an IP address via DHCP. If not,
the radio will appear with an IP address of 0.0.0.0 as shown above.
6. Assign it a valid IP address for the network. Do this by right-clicking on the
radio’s row in the IH Browser display and selecting Assign IP from the context
menu.

2.2 Setup Repeater Radio
Since we haven’t changed any factory-default configuration parameters in the
Master radio (other than to make it a Master), additional RLX2 radios in their
default shipping configuration should link to it as soon as power is applied to
them.
1. Attach power to another RLX2 radio. The Ethernet cable does not need to be
attached to it at this time.
2. After the radio is booted, the radio should appear in the IH Browser:
Note that the Repeater radio above (whose MAC address ends in BF in the
above example) has linked to the Master (whose MAC address ends in BE)
and there is a signal strength indication of –85 dBm.
3. Attach an Ethernet cable, and assign a unique IP address to the Repeater. In
this example, the Repeater is assigned an IP address of 192.168.1.251:
After setting the Repeater’s IP address, remove its Ethernet connection.

2.3 Setup Client Radio
RLX2 radios can be configured in Client mode. Client mode radios only support
one wired network device, but can connect to third-party 802.11 Access Points.

Client mode radios are not often necessary in Industrial network applications. If
the need for a Client RLX2 radio in the system is not needed, this example
configuration can be skipped.
The most straightforward way to test a Client mode radio configuration is with a
second PC connected as the downstream network device from a Client radio. We
will assume such a setup in the following example, and will connect to the Master
radio we configured previously.

Industrial Hotspots User Manual
3 Planning the Network
Before configuring and installing the wireless network, it may help to create a
plan. The following points assume a bridge network of masters and repeaters.
Clients can also be configured to work with devices on existing wireless LANs.
For information, see Setup Client Radio (page 28).
The simplest way to design the physical network of radios, antennas, connectors,
cables, amplifiers and other accessories, is to use ProSoft Wireless Designer
(page 32). This is a freely-available software application that determines the
hardware needs based on the user’s answers to a few questions.
The software will generate a Bill of Materials specifying all the components
needed for the installation. ProSoft Wireless Design is included on the optical
media supplied with the RLX2 radio, and is also available for downloading from
the ProSoft website.
To begin, identify the potential radio locations. For example, the master radio
may be installed near a PC in a central plant location (This PC can configure
the radios through the Radio Configuration / Diagnostic Utility). If the plant is
an oil refinery, for example, radios may need to be installed near the oil tanks.
The next important issue is how to link the radios. Unless the radios are very
close together, make sure that each pair of radio antennas in the network has
a line of sight between them. In other words, visibility is needed from one
antenna to another, either with the naked eye or with binoculars.
If a line of sight does not exist between antennas, an additional site is needed
for installing a repeater radio. This site will create a bridge between the radio
antennas.
Choose the appropriate antennas for the network. If an antenna will be
connected to the radio by a long cable, a power amplifier (available from
ProSoft Technology) may be needed. The more distance between an
antenna and its radio, the more signal loss the radio will have.
ProSoft Wireless Designer can suggest suitable antennas for the application
based on frequency band, data rate, distance, power output level, and other
factors.
Consider drawing up the network plans on paper. As part of the drawing,
assign a logical name to each radio. These names can be assigned in the
Radio Configuration / Diagnostic Utility.
As part of the planning, a site survey may be helpful. ProSoft Technology can
perform this survey, or hire a surveyor, or survey it on your own.
Protect radios from direct exposure to weather, and provide an adequate,
stable power source. Make sure the plan complies with the radio’s power
requirements and cable specifications.
Important: Radios and antennas must be located at least 8 inches (20 cm) away from personnel.

3.1.1 Installation Questions
The following questions will help in getting familiar with the system.
How many radios are in the network?
Master ID:
Repeater ID:
Client ID:
Locations:
Is there a Line of Sight between them?
What type of antennas will be used in
the network?
3.1.2 Planning the Physical Installation
A network's performance is affected by attributes specific to the installation site.
Consider the following cautions, where possible, to optimize the network
installation:
Design the network to use less than 2048 radios (per network)
Place radios within the specified 15 miles of each other
Add repeater to extend distance or where line of sight is limited
Radios or antennas CANNOT be placed within 8 inches (20 cm) of where
people will be
Though radio frequency communication is reliable, sometimes its performance
can be affected by intangibles. A good network installation plan includes time
and resources for performance testing and installation changes.
Test the installation plan (page 39) before the network installation is complete.

If possible, configure all the radios side by side in an office setting and make sure
they link before installing them in the field. If feasible, test with the radios and
end-device equipment together before they are installed in the field.
Important: If the radios are close enough to each other that their received signal strength is
greater than -40dBm, performance may be degraded. Disconnect antennas from radios during
bench testing, or move the radios further apart from each other.
Tip: To make it easier to physically identify the radios, apply a label to each radio indicating the
radio name and IP address.
After each radio is configured using the IH Browser and the web configuration
form, install the radios and test their performance. Install the radios in their
proposed permanent locations.
Temporarily place each radio’s antenna near its proposed mounting location. The
temporary placement of the antenna can be done by hand. Make sure to monitor
the radio’s signal strength.

4.1 Connecting antennas
Each radio must have an antenna connected to the Main antenna port on the
RLX2 radio; without an antenna for each radio, the network will not function if the
radios are more than a few meters apart.
All antennas for radios that communicate directly with each other should be
mounted so they have the same antenna polarity. Small antennas with a reverse-
polarity SMA connector can be mounted directly on the radio. Screw the antenna
onto the antenna port connector until it is snug.
Larger antennas and antennas that do not have a reverse-gender SMA
connector must be mounted separately and connected to the radio using a
coaxial antenna cable. Because the antenna cable attenuates the RF signal, use
an antenna cable length that is no longer than necessary to ensure optimum
performance.
Important: If the radio is to be used in a hazardous location, the radio must be mounted in an
enclosure approved for hazardous locations. The radio requires a separate cable connection to the
SMA connector that leads to an internal antenna.
4.2 Test the Network Installation Plan
Test proposed installations before finalizing the installation.
After the network and radios are configured:
Install the Master radio in its proposed permanent location
Cable the Configuration PC to the Master radio
Place the Remote radios in their proposed locations
Temporarily place each radio's antenna near its proposed mounting location.
The temporary placement of the antenna can be by hand. However, one
person must hold the antenna while the other person monitors the Remote
radio's signal strength displayed on the Configuration PC.
To improve the signal quality of each Remote radio:
Increase the height of the antenna's placement
Use higher-gain antennas
Increase the radio's transmission power, cable the radio to the Configuration
PC, and reconfigure it
Select a new location for the Remote radio and/or its antenna
Decrease the length of antenna cable
Determine and resolve sources of "electrical" noise which may be interfering
with the radio transmission
Add a repeater between the radios that are not communicating, or
reconfigure an existing radio as a repeater if line of sight is available

Once the power cable and Ethernet cable are connected to the radio, the
Power/Status LED should illuminate green. The SPEED LED should indicate a
valid wired link. The RF Transmit and RF Receive LEDs should start to blink
occasionally.
For Repeater or Client mode radios, all three Signal Strength LEDs will blink just
after the radio links to the Master’s signal but before it has been fully
authenticated. Normally this lasts only a few seconds. If it lasts longer or never
turns solid it usually means the encryption keys are not correct.
5.4 Retrieve the default password
If the password is unknown, the user will be unable to change the radio settings.
The user can retrieve the default password to use the software again, but will
lose all the settings that were programmed before.
To retrieve the default password and return the radio to its default settings:
1 Turn off power to the radio.
2 Locate the reset button hole.
3 Insert the end of a paperclip or similar device into the hole to press the reset
button.
4 While holding the reset button in with a paperclip, attach power to the radio,
and continue to hold down the reset button for 30 seconds.
5 The radio will be reset to its default settings, including the password. The
user should now be able to log in using the default password, which is
password.

5.5 Troubleshoot IH Browser error messages
One error message commonly occurs when using the IH Browser, "Unable to
scan for AP's".
This error occurs when the IH Browser attempts to scan for radios and no valid
network connection exists on the PC, wired or wireless.
To correct this error, Confirm the PC has at least one active network (LAN)
connection. It could be a wired Ethernet connection or a wireless 802.11
connection.
Confirm the network connection has a valid IP address. The network connection
might need to have a static IP address assigned to it. Check the IP address of
the network connection to determine that one has been assigned.
5.6 Troubleshoot Missing Radios
If radios are not visible in the IH Browser, try the following:
First, click the SCAN button again. Scans are sent as broadcast messages,
which can be dropped in RF connections, requiring the user to scan again.
Second, disable any software firewall running on the PC (This is most
common in Windows XP and newer). Open the NETWORK CONNECTIONS
folder in the Windows Control Panel, then open the LOCAL AREA CONNECTION
PROPERTIES window and verify that the check box under INTERNET
CONNECTION FIREWALL is not checked.
If the preceding approaches do not help, the PC running the IH Browser and
the radios are probably not connected to the same local network. Verify the
connections.
In topological view, any unlinked radios may be at the bottom of the window.
Scroll down to see all radios. If the radios still cannot be seen in the IH
Browser, call technical support.

Field
Description
802.11 Mode
Present only on the RLX2-IHNF radio. There are three possible mode
settings:
802.11a/g
The radio acts as an 802.11a radio on the 5 GHz band, and an 802.11g
radio on the 2.4 GHz band. Data rates will be limited to the 802.11 a/g
rates (54 mbps maximum). 802.11n operational features will be
disabled. It is not necessary to select this mode for RLX2-IHNF radios
to link to other RLX2 or RLXIB series radios; they will link their best
possible speeds regardless of mode. This mode is not commonly used.
It is mainly used to allow 802.11 a/b/g client devices that cannot link to
802.11n devices to work. One example of such a device is the ProSoft
1734-AENTR wireless I/O client.
802.11n
Default operational mode of the RLX2-IHNF radio. All 802.11n features
are operational, and 20 MHz wide channels are used.
802.11.n wide
Utilizes adjacent pairs of 20 MHz-wide channels as a single 40 MHz-
wide channel. This allows the fastest data throughput to other 802.11n
devices. Only 802.11n devices can utilize this mode, but all RLX2
radios will link at their best speed regardless of mode.
Channels in the 5 GHz band are 20 MHz apart, so 802.11n wide mode
occupies only two channels in that band. However, channels in the 2.4
GHz band are spaced only five MHz apart, so 802.11n wide mode in
the 2.4 GHz band occupies eight adjacent channels! Since there are at
most 13 channels in the 2.4 GHz band, and only three channels do not
overlap others, it is not recommended to enable wide mode on 2.4 GHz
band channels.
Channel list (master
radio)
Indicates the channel number as well as the frequency for operation in
the 2.4 GHz or 5 GHz bands. The available channels in the radio will
vary based on the model and country configuration. Please see section
0 for a comprehensive list of all frequencies for all RLX2 radio models.
RLX2-IHNF radios can operate on 5 GHz
frequencies that are subject to Dynamic Frequency Selection
regulations, and have a special channel selection called DFS Auto
Select. See section 6.8.2 for further details
Important: When choosing an antenna for use with the RLX2 radio,
make sure it supports the frequency range set in the configuration for
the radio.
Repeater
Configures a radio as a repeater. The repeater mode is the normal
radio mode for the network, while the master mode is more of a special
setting to establish the network channel and define the root of the
network tree. Repeater radios help extend the range of a network and
help create the signal "bridges" that allow networked radios to
communicate. All RLX2 radios are capable of repeating.

Field
Description
Parent MAC
MAC Address of the radio’s Parent node. In the example above, the
Repeater is not linked to a Master radio so the Parent MAC is shown

Parent Selection Method
Automatically Choose
Best
The Automatic Parent Selection algorithm uses a calculation to create
a “cost” metric for each possible parent radio that it detects.
In the calculation the radio includes,
RSSI - Stronger signals receive a lower cost.
Hop Count - Fewer hops from the Master radio is given preference
and therefore a lower cost
Choose this setting to allow the radio to determine the best parent to
select.
Parent Branch Length
RLX2 radio will choose its parent strictly by the number of repeaters
between it and the Master radio. If a Branch Length of 1 is chosen, the
RLX2 radio will link only to the Master radio. If a Branch Length of 2 is
chosen, the RLX2 radio will link only to another RLX2 radio that is
linked to the Master radio, and so on.

User Manual Industrial Hotspot
Field
Description
Preferred Parent
RLX2 radio will select its parent from a list of possible parents specified
by the user. The user can list up to eight radios to choose from.
Best in List
When Best in List is selected the radio will select its parent using
the "Automatic Parent Selection" algorithm, but it will limit the
selection to the list of radios in the list. Therefore, the radio in the
list with the lowest cost according to the algorithm will be chosen
as its parent.
Follow List Priority
When Follow List Priority is chosen the radio will select its parent
from the list giving preference to the 1st entry followed by the 2nd
entry and so on.
Parent Selection Parameters
Signal Strength
Threshold
When the signal from a parent reaches a high enough value, a stronger
signal will not improve the quality of the link any further. For signals
that are above that threshold, only fewer hops from the Master give
preference. The threshold can be adjusted here.
Rate to Parent
The default setting is Auto which allows the radio to select the best rate
to use to the parent radio, and adapt over time. Specify a fixed rate
rather than auto for example if the link to the parent has a low signal
strength in which case fixing a lower rate can improve performance.
The actual rate used between this radio and its parent is the lower
value of this setting and the Max Data Rate setting in the parent (see
Max Data Rate). So use these two controls in conjunction if desired to
tailor the rate of each parent link.
Roaming Parameters
Optimize Fast Roaming
Parameters
In typical Fast Roam applications a Repeater is installed on a mobile
pallet or platform and a set of Master units forms a backbone
infrastructure network, through which the Repeater must roam. To
obtain fast roam times, Spanning Tree must be disabled and SSID's
not hidden on the Master. The Repeater should be configured to not
allow child Repeaters and to use a Signal Strength Threshold set high
enough such that RSSI is used to determine the link cost to a parent.
Checking the checkbox in this section automatically sets these
parameters accordingly along with a predetermined optimum value for
the cost threshold. Unchecking it will revert the parameters to their
previous values before the check box state was saved.
Note: All Spanning Tree configurations and Hide SSID must be
disabled manually on all Master units as this dialog box is only
accessible when in Repeater mode.
It is always possible to subsequently change any of these parameters if
it is so desired, for example to set a different value for the Signal
Strength Threshold. If this is done then the control will not display as
checked as it will only display as checked if all three parameters have
the preset values.

After a selection is saved and return to the Radio Network Settings panel, notice
the selection is indicated under the Parent Link button.
The Automatic Parent Selection algorithm uses a calculation to create a cost for
each possible parent radio that it detects. The following graph describes how the
cost is calculated when the signal strength threshold is set to -60 dBm.
Once per second, the RLX2 radio evaluates the link it has to its parent to
determine if this link is the best parent to use. A cost is calculated for each entry
and can be seen in the column labeled "Cost" in the preceding table. The cost
calculation is based not only on the strongest signal, but on several other factors
to provide optimum network communication.

If more control is needed than the automatic algorithm allows, a priority list of
parents for the RLX2 radio can be defined.

6.2.2 IGMP Settings
RLX2 radios support IGMP v1 and v2. The default operation of the RLX2 radios
is to have IGMP functionality enabled, although the user can disable IGMP
entirely. Additionally, the user can specify settings associated with IGMP filtering
and snooping. Unknown multicast addresses can be sent to all ports (flood) or to
none (filtered) by changing the IGMP Multicast Filtering option. The user can
specify whether the radio will generate IGMP queries, and configure the query

6.2.3 Rapid Spanning Tree Functionality
The software’s built-in Rapid Spanning Tree (RSTP) functionality enables the
setup of full redundancy between radios or other devices. Spanning Tree shuts
off ports as necessary to prevent loops. If loops are created in an Ethernet
network, packets can be circulated endlessly, consuming all the bandwidth and
making the network unusable.
Important: All radios in a network must have the same Spanning Tree configuration (enabled or
disabled.) Radios will not link if some of them have Spanning Tree enabled while others do not.
RSTP allows users to create truly redundant connections between any two points
in the network. The radios detect the redundant paths and keep one connection
alive for communications. If the primary connection fails for any reason, the
secondary connection is quickly transitioned to a state to forward packets,
allowing the network to adapt itself to handle problems without customer
intervention.
RSTP uses active communications between network devices to propagate
changes in the network and to cause transitions to occur much more quickly.
Because RSTP is an IEEE standard, RLX2 radios work in conjunction with wired
Ethernet switches to form a redundant network. Spanning Tree details are
described in the IEEE 802.1D series of specifications.
Each RSTP device (RLX2 Radio or Ethernet switch) communicates with other
RSTP devices in the network via packets called Bridge Protocol Data Units
(BPDUs). BPDUs are sent out each of the devices ports. In a wired switch this
would be from each of the Ethernet ports. In an RLX2 Radio, in addition to the
Ethernet port, each wireless link is considered a port. These BPDUs are the
communications means to allow each RSTP device in the network to make sure
that the proper connections still exist.

User Manual Industrial Hotspot
In the following illustration, the RLX2 Radio has 4 RSTP "ports":
Ethernet port (1)
A port for its parent connection (2)
A port for each of its two child connections (11 and 12).
BPDUs are sent out the port at a rate called the "Hello Time". The accepted
standard value for this is 2 seconds. If a radio (or any other RSTP device) does
not get a BPDU for 2 Hello Times, it assumes the RSTP device that had been
there is no longer available. It can then open an alternate path if one is available.
This process is much like the STP process. If other devices on the network are
not operating in rapid spanning tree mode, the radio will revert to normal
spanning tree operation on a per-port basis.
RSTP provides a performance enhancement over STP operation. By
comparison, the radio using the STP algorithm would revert its port to the
listening state, and then to the learning state, before returning to the forwarding
state. Each of these states takes at least 15 seconds, during which the STP
devices are listening for BPDUs to re-negotiate the network topology. The
advantage of using the RSTP functionality is that is uses active handshaking
between adjacent RSTP devices to re-negotiate the network topology. This
process takes one to two seconds.
Each RLX2 Radio contains a switch table, which tells it how to forward Ethernet
packets to get them to their proper destination. When the network topology
changes, the RLX2 Radio the Ethernet switch table is flushed immediately. This
allows it to pass traffic immediately over the new network topology and learn the
configuration in the process. Until the learning is complete, the packets are
broadcast to their destination. As each packet is seen and the switch table
rebuilds, the radios return to directing packets to their destinations.

6.2.4 Spanning Tree Settings
Field
Description
Enable Spanning Tree
Spanning Tree is enabled when this box is checked. Without spanning
tree, redundant connections might exist if multiple radio links are
created in parallel with each other. Redundant connections are
blocked only if spanning tree is enabled. Additionally, spanning tree is
used to flush the Ethernet switch table when the network topology
changes as described in the section on Automatic Parent Selection.
The default setting for Enable Spanning Tree is disabled. Note that
many network switches implement spanning tree functionality
themselves, which if enabled, will cause conflicts if Spanning Tree is
also enables in the radio. Check the documentation and settings for
the wired network equipment before enabling Spanning Tree in the
radios.
Ethernet Edge Port
Because RSTP is an active protocol, it depends on communication
between RSTP devices. If no RSTP device is connected to the radio’s
Ethernet port, the handshake cannot take place. In this case RSTP
reverts to STP. This means that the Ethernet port will be forced to
adhere to the timer based transition protocol of STP.
Therefore on network transitions and power up, communications will
not be allowed over the Ethernet port for 30 to 45 seconds. This
setting is an indication that no redundant connections exist out this
port and communication can immediately be allowed. If for some
reason a BPDU is received on this port, the RSTP protocol will
negotiate properly and handle any possible redundant paths.
The recommended setting for Ethernet Edge Port is "Enabled".
Bridge Times Configures the timing intervals to use.
Priority
Determines who should be the root of the RSTP. The RSTP device
with the lowest priority becomes the root. The accepted standard value
for this is 32768. If wired switches exist in the network that support
RSTP, they should always be allowed to be the root.
Set this value to 32769 to prevent the radio from being the root over a
wired switch. Use this setting when a radio is configured to be a
Master.
Set this value to 32770 when the radio is configured to be a Repeater.
In this way, if only RLX2 radios exist in the network, the Master radio
will become the root.
Hello Time
Rate at which BPDUs are sent out. The industry standard is 2
seconds.

Max Age
Measures the age of the received protocol information recorded for a
port and ensures this information is discarded when its age limit
exceeds the value to the maximum age parameter recorded by the
switch. The timeout value for this timer is the maximum age parameter
of the switches.
Forward Delay
Monitors the time spent by a port in the learning and listening states.
The timeout value is the forward delay parameter of the switches.
Path Costs RSTP and STP algorithms use a cost to determine which connections
should be used. The "spanning tree" is formed by determining the
least cost paths from any RSTP device back to the root.
Wireless
Gives preference to a wired connection, set the Wireless cost to 200.
Ethernet
Gives preference to a wired Ethernet connection, set the Ethernet cost
to 100.
Multiple master radios can be defined on the same network. If one master radio
goes down, any radios linked to it can switch over to the other master, so the
networked radios remain connected and transmitting. In order to be redundant,
the two masters should typically be on the same segment—in other words, they
should be wired together into the same switch. These two masters can be
assigned different channels to increase network bandwidth, but they must be
assigned the same SSID.
Also, because all radios are repeaters, each radio can be configured to reach a
master radio via multiple repeater paths. If a repeater goes down, the linked
radios can use a different path to get back to a master radio.

6.2.5 Advanced Settings
It is important to allow many industrial protocols to communicate properly over
the RLX2 radios. The standard 802.11 AP operation for transmitting broadcast
messages is to accumulate them and transmit them only on specific time
intervals. This allows clients that are in power-save mode to wake up at the
synchronized time interval and receive the broadcast packets. However, the
power-save mode is rarely used in industrial networks.
Additionally, many industrial protocols utilize multicast traffic, which is sent as
broadcast messages over the wireless network. By enabling immediate
broadcasting, these multicast messages are not delayed by the wait for the next
time interval to occur before they can be transmitted. This results in improved
network performance.
The settings on this form also allow the configuration of the transmission rate and
broadcast mode to optimize this radio's use on an industrial network.

current operating conditions. The system attempts to use a 400
microsecond Guard Interval, but will fall back to an 800 microsecond
Guard Interval if excessive data corruption is detected. The radio will
periodically attempt to resume using a 400 microsecond Guard Interval
as conditions improve. A 400 microsecond Guard Interval results in
about 11% more throughput than using a 800 microsecond guard
interval. The user has no control of the Guard Interval.
As seen in the table above, absolutely best throughput requires
802.11n wide mode, more than one antenna, and a RF environment
capable of supporting a 400 microsecond Guard Interval.
Max Basic Rate
In addition to the Data Rate setting which controls generic data traffic,
the Basic Rate setting adjusts the rate at which control packets such
as Beacons and ACKs are sent at as well as packets that need to go
to the whole network such as Broadcasts. Because these packets are
intended for the whole network, the Max Basic Rate setting of the
Master is advertised to each of the radios in the network through
Beacons. Each radio, other than the Master, then inherits the Max
Basic Rate setting of the Master. Therefore the setting only needs to
be made in the Master radio. The setting in each of the other radios is
disregarded.
Immediate Broadcasting
Forward multicast traffic immediately, rather than waiting for specific
time intervals.
Block General Probe
Requests
Do not respond to general probe requests that are not specific to the
radio's SSID.
Range
Allows the radios to account for round trip delays. The Range settings
should be the same in all radios in the network and should be at least
large enough to account for the length of any links. However,
increasing the Range beyond what is necessary can cause a slight
decrease in throughput. The default Long range is 25km, which is valid
for all operating modes of all radios.
TX Power Attenuation
Allows reduction of the radio’s output power.. The range of attenuation
is from 0 to 18 dB. Radios are shipped from ProSoft configured for
maximum output power. This is either the maximum output power of
the radio itself, or the maximum power allowed by country for which
the radio is configured. However, it is possible to attach an antenna
with so much gain that the maximum legal allowed radiated power is
exceeded. This control allows the reduction of power when using such
antennas so that output power is still within legal limits. See section
8.4 for information on output power regulations by the FCC for the
USA.
Note that higher gain antennas provide better performance in both
receive and transmit functions, while output power only increases
transmit performance.

Active Antennas
This control is only available on the RLX2-IHNF radios. The default is
set to A Only. The other options are A, C (for two antennas) and A, B,
C for three antennas. Note that if two antennas are used, they must be
attached to the ANT A and ANT C antenna connectors.
MIMO antennas generally will have three connections so all three
antenna ports must be activated. In general, operation with three
antenna ports will give best performance. When more than one
antenna port is active, the radio will monitor the signal appearing at all
antenna ports and dynamically select the port(s) with the best signal.
However, there are situations where performance may improve if
fewer antenna ports are active. If radios are very close together
(typically a few feet), all three antenna ports will receive essentially
identical signal strengths and the radio may continuously change
antenna ports, resulting in degraded performance.
SD Auto Write Enable
Enables the unit to write a copy of its Configuration to the SD Card
whenever new settings are saved from any pages of the unit's web
interface. Previous Configuration files are renamed with a unique file
name which allows auditing of changes made to the unit's settings.
SD Auto Clone Enable
Enables the unit's Clone function. On power up if an SD Card is
present that has a Configuration file different from the unit's current
Configuration the unit will adopt the settings from the SD Card. If the
Configuration matches or there is no Configuration file on the SD Card
then no action is taken. On inserting an SD Card into a running unit, if
the Configuration file found on the SD Card will result in the unit's
settings being changed on Powerup or Reset, a warning is indicated
by flashing the Signal Strength, MOD and NET LEDs.
In order to save this control as enabled, either an SD Card must not be
present, or the SD Auto Write Enable control must also be checked
when saving. If these conditions are not present the control will be
disabled before saving, to prevent the unit from reverting back to a
Configuration file on the SD Card after reset.
To adopt the Configuration file on an SD Card when this control is
already enabled, simply insert the SD Card and power cycle the unit. If
this control is not enabled, first enable and save the setting without the
SD Card inserted and then insert the SD Card and power cycle the
unit.
NOTE: Do not enable Auto Write if you do not want the active
Configuration file on the SD Card to be replaced when the unit adopts
and saves the SD Card's current Configuration file.
Write SD Card
Immediately writes a copy of the unit's Configuration file to the SD
Card, independent of the Auto Write check box setting. Note that the
configuration files are in a binary format so sensitive data (e.g.
passwords, encryption keys) cannot be easily read from the files.

6.3.1 Encryption type
The preferred encryption type is WPA (WiFi Protected Access). Select WEP
(wired equivalency protocol) for use with an older client radio that only has WEP
encryption. For compatibility with clients that do not support WPA, select
WPA+WEP128 (bits) or WPA+WEP64 (bits) as the encryption type. The older
clients can connect to an access point using the WEP setting, but new clients will
use WPA and the RLX2 radios will still use WPA among themselves.
IMPORTANT: If WPA+WEP is selected, some clients using WPA might not be able to connect
unless a WEP key other than number 1 is used, due to limitations in these clients. In such cases,
set a WEP key other than key 1 and set this same key in all clients that are using WEP. See WEP
key (page 80).
WEP is the original security protocol used by 802.11 networks, but WPA offers
better protection against attacks, for several reasons: WPA distances the
encryption key from the actual data by performing several algorithms to the key
before generating the encrypted data, it performs dynamic key management by
changing keys frequently, and it performs message integrity checks to prevent
forgery and replay.
Selecting WEP 128, WEP 64, or None (no encryption) as the encryption type is
possible, but none of these settings are recommended.
Note: If an RLX2 radio is set to use WPA+WEP, it will connect to other radios set to WPA only or
WPA+WEP, but it will not communicate with radios set to WEP only. Likewise, an RLX2 radio in
client mode with WPA+WEP selected will not connect to an access point with WEP only selected.

To use WPA encryption on packets sent between the radios, enter a WPA pass
phrase of between eight and 63 normal keyboard characters. This phrase

Note: Clients often support more than one WEP key. Packets received can be decrypted using any
one of the keys if programmed, but packets are always transmitted with the "default" WEP key
number. If a transmit key number is set on the RLX2 radio, make sure all other radios and clients
have this key programmed. To set keys other than key 1 on some clients using Windows,

6.4 Radio access settings
The following fields appear in the Security Settings area on the right side of the
Radio Configuration window.
In order to configure or diagnose a radio using its built-in Web server or SNMP
agent, both the computer and the radio must have IP addresses. These IP
addresses must be on the same subnetwork. An IP address is only needed to
configure the radio and view its diagnostic settings. Otherwise, the address is
unnecessary.
Field
Description
Obtain IP address -
DHCP
Allows the radio to obtain its IP address from a DHCP server.
Use the following IP
address
Specifies a Static IP address to the radio. Enter the IP address
information in the following fields.
IP Address
Use an IP address that will not interfere with any other devices on the
network. Request a block of IP addresses to use from the Network
Administrator.
Subnet Mask
Subnet Mask provided by the Network Administrator.
Default Gateway
Default Gateway address provided by the Network Administrator.
Primary DNS
Primary DNS address provided by the Network Administrator.
Secondary DNS
Secondary DNS address provided by the Network Administrator.
SNMP button
Opens the SNMP (Simple Network Management Protocol) Agent
settings form. Use this form to configure access to radio network
settings through an SNMP agent.
Login Password button
Configures the Login Password for the radio. The default password is
"password". Change this password and keep a record of it in a safe
place, to protect the radio from being reconfigured by unauthorized
users.
DHCP (Dynamic Host Control Protocol) is a service provided by a server
(typically a router or a firewall) on a local area network. Devices on a network
that supports DHCP can request and receive an IP address from the DHCP
server. RLX2 radios support DHCP; by default, they attempt to obtain an IP
address from a DHCP server.
If a DHCP server is not available, the radio will not be able to acquire an IP
address automatically. Therefore, assign an IP address, subnet mask and
default gateway to the radio so that it can communicate on the network.

Assign a Static (fixed or permanent) IP address to the radio to make it easier to
identify and configure the radio. Static IP addresses are particularly useful when
configuring radios to serve as Access Points, or for radios that must be
accessible through a firewall.
A detailed discussion of TCP/IP networking is beyond the scope of this manual.

6.4.1 SNMP Agent settings
SNMP is a network management protocol that is often used with TCP/IP and
Ethernet. As an alternative to using the Radio Configuration / Diagnostic Utility,
changing radio settings and viewing diagnostics can be done in an SNMP
manager application.
Field
Description
Enable
Enables the following SNMP Agent settings.
Allow Any Manager
Allows any user to change the radio settings from any computer using
SNMP.
Allow IP
Restricts access to an SNMP manager with a particular IP address.
Enter the IP address in the Allow IP field.
Community String
Enter a "community string" (essentially a password) that a manager
must use to access the radio’s SNMP agent.
Permission
Select the permission level to assign to this radio.
Read only
An SNMP Agent can view but cannot modify radio settings.
Read/Write
An SNMP Agent can view and modify radio settings.
Save
Saves the changes and updates the radio configuration.
Cancel
Discards the changes without updating the radio configuration.
The RLX2 SNMP agent supports SNMP protocol version 1.4 and 2 MIBs:
RFC12133-MIB (partial; internet.mgmt.MIB-2.system, .interfaces, .snmp)
ROMAP-MIB (included on the DVD; internet.private.enterprises.romap)
It also supports a selection of standard SNMP traps, including Cold Start, which
is sent when the radio initializes.

Important: This action discards all the radio configuration settings.
A prompt to confirm this action will appear before changes take place.
6.8 DFS Support
Some channels in the 5 GHz band are shared with radar and must adhere to
Dynamic Frequency Selection (DFS) rules. This means that if the radio detects
the presence of radar on its operating frequency, it must automatically change to
another frequency.
6.8.1 Master Radio Operations
If radar is detected on an operating channel, transmissions must cease within the
required Channel Closing Transmission Time, and must move to a new channel
within the required Channel Move Time. Before transmitting on a new DFS
channel that has not been previously checked for radar, the Master radio must
monitor the channel for the Channel Availability Check Time before transmitting.
Operations cannot return to a channel where radar was detected for at least the
Non-Occupancy Period. The values for these parameters are noted in the table
below:

Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n
User Manual Industrial Hotspot
If a Master radio detects radar, it issues a channel change announcement to all
Clients and Repeaters in the network. Then it moves to a new channel within the
Channel Move Time. (Typically, this move time is 500 milliseconds or less.) If the
selected channel was not previously checked for the presence of radar, the
Master radio must do so for the Channel Availability Check Time before it can
begin to transmit. If the newly-selected channel is not a DFS channel, or if the
channel was previously monitored for radar since the radio was powered on,
transmissions can begin immediately.
During the Channel Availability Check Time, a radio blinks all three amber Signal
Strength LEDS approximately once per second. If radar is detected on the new
channel during the Channel Availability Check Time, the Master randomly selects
another channel and begins the process again.
If a Repeater in a network detects radar, it will notify the Master to change
channels.
6.8.2 DFS Auto Select
One of the Master channel selection options is DFS Auto Select.
With this selection the radio randomly selects a DFS channel for operation. The
actual channel in operation is always shown in the Current Channel display:

7.3.3 Update Firmware
"Firmware" is the program that runs in the RadioLinx® 802.11abg Industrial
Hotspot that allows it to communicate and exchange data between devices,
using the radio as a network connection. Different versions of the firmware
communicate with other radios in different ways, and provide different levels of
functionality.
In order for the RadioLinx Industrial Hotspot radio to communicate with other
RLX2 devices, all radios on the network must use the same firmware version.
To change the firmware version of the radio:
1 Start RadioLinx Industrial Hotspot Browser.
2 Open the Operations menu, and then choose Update Firmware.
3 Enter the password for the radio. This is the same password used to log into
the radio from the Radio Configuration / Diagnostic Utility (page 48).
4 Click the Browse button to locate the Image File (firmware version) to update.
Both versions of firmware are available both on the DVD that came with in the

minimum of 2, but can be higher if there are additional
hops to the Master. Client devices do not display a hop
value.
Parent
The MAC address of the Parent radio to which this
Repeater or Client is linked. Not shown for Master
devices.
Associations
The number of network elements to which a radio has a
wireless connection.
Bridges
The number of device to which this device has a

8.1 Product Overview
The RLX2 radio is an industrial high-speed Ethernet radio. Use it in place of
Ethernet cables to save money, extend range, and make connections that may
not otherwise be feasible. The radio operates as a wireless Ethernet switch. Any
data that can be sent over a wired network can also be sent over the radio.
The RLX2 radio series is certified for unlicensed operation in the United States,
Canada and Europe at 2.4 and 5 GHz. With approved high-gain antennas, the
radios can achieve distances of over 5 miles line-of-sight between them. Multiple
repeaters can be used to extend this range to far greater distances.
A highly reliable wireless network can be developed by creating redundant (page
69) wireless paths. Multiple master (page 58) radios can be installed without any
special programming or control. Repeater (page 58) radios can connect to any
master at any time; if one master goes down, the repeater connects to another.
Likewise, if a repeater goes down, any repeater that was connected to it can
reconnect to a different repeater, keeping the network intact. Create large, self-
healing tree-like networks can be done in this fashion. Fully redundant paths are
possible because the Spanning Tree (page 69) protocol in the radios disables
and enables paths as necessary to avoid Ethernet loops, which would otherwise
halt communications.
In addition to acting as a switch, every master or repeater radio in an RLX2
wireless network can simultaneously act as an 802.11 a, b or g access point.
This allows 802.11 WiFi clients to connect and roam between radios for
monitoring of the wireless network or general network access. The RLX2 has a
special client mode (page 37) that allows connection of any Ethernet device to
any existing 802.11 a, b or g access point, regardless of the brand (An example
of an 802.11 client is a laptop with a WLAN card).
Note: Wi-Fi is a trademark of the Wi-Fi Alliance, used to describe the underlying technology of
wireless local area networks (WLAN) based on the IEEE 802.11 specifications.

A high level of security is inherent with AES (Advanced Encryption Standard)
encryption. TKIP (Temporal Key Integrity Protocol) is also available. If
necessary, adding WEP128 or WEP64 (Wired Equivalent Protocol) encryption in
addition to AES or TKIP for clients that do not support AES can be done. A
simple Media Access Control (MAC) filter table restricts the radios or clients that
can link to a selected radio according to the MAC IDs entered in the table.
The radio is designed for industrial applications with a metal enclosure, DIN-rail
mounting, and shock and vibration tested to IEC 60068.
The RLX2 radio series is easy to use. Use the Radio Configuration / Diagnostic
Utility, which runs in a web browser, to configure the radio. Also, an SNMP
manager can be used for configuration. The radio comes with a Windows-based
utility called IH Browser. It finds all the radios on the network and lists
information about them. A topology view in the IH Browser shows how the
wireless network is linked together at any point in time. Firmware updates can be
done at anytime from anywhere on the network. This includes over the wireless
link or over the Internet.
ProSoft Technology radios can easily be installed into new or existing systems.
The software and manuals can be downloaded from the DVD or ProSoft
Technology’s web site at www.prosoft-technology.com.

8.2 Compatibility with ProSoft RLXIB Series Radios
The RLX2 series radios are 100% functionally compatible with ProSoft’s legacy
RLXIB-IHA, RLXIB-IHG, and RLXIB-IHW radio models. This allows customers with
RLXIB series radios to add RLX2 radios to their existing networks without any
reconfiguration of existing assets or obsolescence issues. The main differences in
the RLX2 series radios are the following improvements:
1 Different enclosure size for more efficient heat dissipation.
2 Faster, more efficient electronics that consume less power.
3 Gigabit Ethernet.
4 MicroSD memory cards for configuration data storage.
5 Internal temperature sensor.
The RLX2 series radios will acquire additional functionality as new firmware features
are added. These new features will not be ported to the RLXIB radios, but the RLX2
radios will continue to work with RLXIB radios using their existing functionality.
The RLX2-IHNF is an 802.11n device that does not have an RLXIB series
equivalent. It cannot function as a repeater to ProSoft’s RLXIB-IHxN series radio
products. Specific differences by product are noted in the following table.
Specifications that have not changed between the RLXIB and RLX2 series products
are not listed.

8.5.1 Radio power requirements
The RLX2 radios accept voltages between 10 and 24 VDC, with an average
power draw of less than 6 Watts. A detachable power connector comes with the
radio, as shown below. The connector terminals are labeled + (positive DC
connection) and - (DC ground connection).
The AC-to-DC power supply adapter supplied with the optional RLX-IHBTK
Bench Test Kit can be used. The DC power wires must be less than 3 meters in
length to meet regulatory requirements.
Important: When wiring the power connector supplied with the radio, be sure to
observe the proper polarity markings on the power connector. Wiring the
connector incorrectly can cause serious damage to the radio which will not
be covered under the ProSoft warranty.
The Power Connector (ProSoft part number 002-0116) is shown on the left in the
photo above. Note the + and – polarity markings. The wire installation tool
(ProSoft part number 357-0061) shown on the right is helpful for installing wires
into the spring-loaded contacts inside power connector.

To use the installation tool, insert it into the connector as shown:
Press down on the installation tool to use it as a level which will open the
connector’s contacts to insert a wire. A properly-wired power connector is shown:
The RLX2 radios accept power from 802.3af Mode B or passive Power over
Ethernet sources supplying 48VDC, with an average power draw of less than 6
watts. ProSoft offers the following passive PoE injectors for use with the RLX2
radios:
POE-48I-AC
Power over Ethernet Injector, AC input
POE-48I-DC-DC
Power over Ethernet Injector, 9 to 36 VDC input voltage
The radio shall be installed by trained personnel only, as outlined to the
installation instructions provided with each radio.

The equipment shall be installed by a qualified installer/electrician. The
installer/electrician is responsible for obtaining a secured ground connection
between the lug terminal on the surge protector to a verified common ground
point using a minimum 6 AWG gauge wire. This must be done when attaching
power lines to the radio during installation.
A solid ground connection should be verified using a meter prior to applying
power to the radio. Failing to secure a proper ground could result in serious injury
or death as a result of a lightning strike.
Using Power over Ethernet (PoE) to power remote devices has several
advantages including:
"Carrier Class" Power Over Ethernet System.
Power can be supplied over long distances, up to 300 feet.
Power can be available wherever network access is available.
The power supply can be centrally located where it can be attached to an
uninterruptible power supply.
The user has the ability to easily power on reset the attached equipment from
a remote location.
There is no need to run additional power cabling to the device as power can
be supplied over the CAT5, CAT5E, or CAT6 Ethernet cable.
Used for remote mounted radios to save on cost of coax and reduce RF
losses.
Built-in Ethernet Surge protection to prevent equipment damage.
Overload and Short Circuit protection.
8.5.2 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs when running at 10 MBit or 100 MBit
speeds. All eight wires are used when running at 1000 MBit speeds.
Category 5e or better cable is recommended for 1000 MBit speeds.
The Ethernet port on the module is Auto-Sensing. Use either a standard Ethernet
straight-through cable or a crossover cable when connecting the module to an
Ethernet hub, a 10/100/1000 Base-T Ethernet switch, or directly to a PC. The
module will detect the cable type and use the appropriate pins to send and
receive Ethernet signals.
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, ensure the
switch position and cable type agree.
Refer to Ethernet cable configuration (page 126) for a diagram of how to
configure Ethernet cable.

In This Chapter
Antennas ............................................................................................. 135
9.1 Antennas
Connecting antennas to the radio, see Connecting antennas (page 39).
Consider important electrical characteristics when selecting antennas:
Antenna pattern (page 135)
Antenna gain (page 136)
Antenna polarity (page 136)
Antenna location, spacing, and mounting (page 141)
9.1.1 Antenna Pattern
Information between two wireless devices is transferred via electromagnetic
energy radiated by one antenna and received by another. The radiated power of
most antennas is not uniform in all directions and has varying intensities. The
radiated power in various directions is called the pattern of the antenna. Each
antenna should be mounted so that its direction of strongest radiation intensity
points toward the other antenna or antennas with which it will exchange signals.
Complete antenna patterns are three-dimensional, although often only a two-
dimensional slice of the pattern is shown when all the antennas of interest are
located in roughly the same horizontal plane, along the ground rather than above
or below one another.
A slice taken in a horizontal plane through the center (or looking down on the
pattern) is called the azimuth pattern. A view from the side reveals a vertical
plane slice called the elevation pattern.
An antenna pattern with equal or nearly equal intensity in all directions is
omnidirectional. In two dimensions, an omnidirectional pattern appears as a
circle (in three dimensions, an omnidirectional antenna pattern would be a
sphere, but no antenna has true omnidirectional pattern in three dimensions). An
antenna is considered omnidirectional if one of its two dimensional patterns,
either azimuth or elevation pattern, is omnidirectional.
Beamwidth is an angular measurement of how strongly the power is
concentrated in a particular direction. Beamwidth is a three dimensional quantity
but can be broken into two-dimensional slices just like the antenna pattern. The
beamwidth of an omnidirectional pattern is 360 degrees because the power is
equal in all directions.

User Manual Industrial Hotspot
9.1.2 Antenna Gain
Antenna gain is a measure of how strongly an antenna radiates in its direction of
maximum radiation intensity compared to how strong the radiation would be if the
same power were applied to an antenna that radiated all of its power equally in
all directions. Using the antenna pattern, the gain is the distance to the furthest
point on the pattern from the origin. For an omnidirectional pattern, the gain is 1,
or equivalently 0 dB. The higher the antenna gain is, the narrower the
beamwidth, and vice versa.
The amount of power received by the receiving antenna is proportional to the
transmitter power multiplied by the transmit antenna gain, multiplied by the
receiving antenna gain. Therefore, the antenna gains and transmitting power can
be traded off. For example, doubling one antenna gain has the same effect as
doubling the transmitting power. Doubling both antenna gains has the same
effect as quadrupling the transmitting power.
9.1.3 Antenna Polarity
Antenna polarization refers to the direction in which the electromagnetic field
lines point as energy radiates away from the antenna. In general, the polarization
is elliptical. The simplest and most common form of this elliptical polarization is a
straight line, or linear polarization. Of the transmitted power that reaches the
receiving antenna, only the portion that has the same polarization as the
receiving antenna polarization is actually received. For example, if the
transmitting antenna polarization is pointed in the vertical direction (vertical
polarization, for short), and the receiving antenna also has vertical polarization,
the maximum amount of power possible will be received. On the other hand, if
the transmit antenna has vertical polarization and the receiving antenna has
horizontal polarization, no power should be received. If the two antennas have
linear polarizations oriented at 45° to each other, half of the possible maximum
power will be received.
9.1.4 Whip antennas
Use a 1/2 wave straight whip or 1/2 wave articulating whip (2 dBi) antenna with
RLX2 radios. These antennas are the most common type in use today. Such
antennas are approximately 5 inches long, and are likely to be connected to a
client radio (connected directly to the radio enclosure). These antennas do not
require a ground plane. Articulating antennas and non-articulating antennas work
in the same way. An articulating antenna bends at the connection.

9.1.5 Collinear array antennas
A collinear array antenna is typically composed of several linear antennas
stacked on top of each other. The more stacked elements it has, the longer it is,
and the more gain it has. It is fed in on one end.
The antenna pattern is torroidal. Its azimuthal beamwidth is 360°
(omnidirectional). Its vertical beamwidth depends on the number of
elements/length, where more elements equal narrower beamwidth. The antenna
gain also depends on the number of elements/length, where more elements
produce higher gain. Typical gain is 5 to 10 dBi.
The antenna polarity is linear, or parallel to the length of the antenna.
9.1.6 Yagi Array Antenna
A yagi antenna is composed of an array of linear elements, each parallel to one
another and attached perpendicular to and along the length of a metal boom. The
feed is attached to only one of the elements. Elements on one side of the fed
element are longer and act as reflectors; elements on the other side are shorter
and act as directors. This causes the antenna to radiate in a beam out of the end
with the shorter elements. The pattern depends on the overall geometry,
including the number of elements, element spacing, element length, and so on.
Sometimes the antenna is enclosed in a protective tube hiding the actual
antenna geometry.
The antenna pattern (page 135) is a beam pointed along the boom toward the
end with the shorter elements. The beamwidth varies with antenna geometry but
generally is proportional to the length (where longer length produces a narrower
beam).
The antenna gain (page 136) varies with antenna geometry but generally is
proportional to the length (where longer length produces higher gain). Typical
values are 6 to 15dBi.

User Manual Industrial Hotspot
The antenna polarity is Linear (parallel to the elements, perpendicular to the
boom).
Refer to the Antenna Types overview section for other types of approved
antennas (page 139).
9.1.7 Parabolic reflector antennas
A parabolic reflector antenna consists of a parabolic shaped dish and a feed
antenna located in front of the dish. Power is radiated from the feed antenna
toward the reflector. Due to the parabolic shape, the reflector concentrates the
radiation into a narrow pattern, resulting in a high- gain beam.
The antenna pattern is a beam pointed away from the concave side of the dish.
Beamwidth and antenna gain vary with the size of the reflector and the antenna
construction. Typical gain values are 15 to 30 dBi.
The antenna polarity depends on the feed antenna polarization.

9.1.9 Antenna location, spacing, and mounting
Consider the following points regarding antenna location, spacing, and mounting:
When placing antennas, ensure a clear line of sight between the master
radio's antenna and all of the other radio antennas.
If the site base contains obstructing terrain or structures, mount the antenna
on a tower or rooftop to provide a line-of-sight path. The line-of-sight
consideration becomes more important as the transmission path becomes
longer.
Mount the antennas as high off the ground as is practical. The higher an
antenna is above the ground, the greater its range.
Mount the antennas away from massive structures. Radio signals bounce off
metal walls, for example, which can compromise a clear signal.
Mount antennas to minimize the amount of nearby metal structures in the
antenna pattern.
Mount the antennas and install radios away from sources of RF interference.
Use the shortest possible antenna cable length. Signals lose power over the
cable's distance.
Choose antennas that are appropriate for the network's intended function.
If antennas are on radios on the same network, mount them so they have the
same polarity. If the antennas are on separate networks, mount them so they
have a different antenna polarity—for example, mount one antenna vertically
and the other horizontally.
Space radios at least three feet (one meter) apart so they do not overload
each other. If antennas must be near each other:
o Mount omnidirectional antennas directly above each other.
o Position directional antennas so they do not point at nearby antennas.
Place antennas side by side if they point in the same direction. Place
antennas back to back if they point in opposite directions.

Default Gateway
The IP address of a network router where data is sent if the destination IP
address is outside the local subnet. The gateway is the device that routes the
traffic from the local area network to other networks such as the Internet.
Device-to-Device Network (Peer-to-Peer Network)
Two or more devices that connect using wireless network devices without the
use of a centralized wireless access point. Also known as a peer-to-peer
network.
DFS
DFS stands for Dynamic Frequency Selection, a requirement for operation on
certain frequencies in the 5 GHz band in many countries. When a radio operates
on a DFS frequency, it must sense the presence of radar and automatically
change to another channel if radar is detected.
DHCP
The dynamic host configuration protocol is an Internet protocol, similar to BootP,
for automating the configuration of computers that use TCP/IP. DHCP can be
used to automatically assign IP addresses, to deliver IP stack configuration
parameters, such as the subnet mask and default router, and to provide other
configuration information, such as the addresses for printer, time, and news
servers.
Direct Sequence Spread Spectrum
One of two approaches (with frequency hopping spread spectrum) for sorting out
overlapping data signals transmitted via radio waves. 802.11b uses DSSS
Directional Antenna
Transmits and receives radio waves off the front of the antenna.
Diversity Antenna
An antenna system that uses multiple antennas to reduce interference and
maximize reception and transmission quality.
DTE
Data Terminal Equipment, for example, a computer or terminal.
Dual Band

EIRP
Equivalent isotropically radiated power (EIRP) is the amount of power that would
have to be emitted by an isotropic antenna (that evenly distributes power in all
directions and is a theoretical construct) to produce the peak power density
observed in the direction of maximum antenna gain.
Encryption
Method of scrambling data so that only the intended viewers can decipher and
understand it.
ESD
Electrostatic Discharge. Can cause internal circuit damage to the coprocessor.
ESSID
Extended Service Set Identifier. A name used to identify a wireless network.
F
Firmware
Firmware is the embedded software code that that runs in the module to direct
module function (similar to the BIOS in a personal computer). This is
distinguished from the Setup/Diagnostic Application software that is installed on
the Configuration PC.
Frequency Hopping
A radio that rapidly changes its operating frequency several times per second
following a pre-determined sequence of frequencies. The transmitting and
receiving radios are programmed to follow the same frequency hopping
sequence.
Frequency Hopping Spread Spectrum
Changes or hops frequencies in pattern known to both sender and receiver.
FHSS is little influenced by radio stations, reflections, or other environmental
factors. However, it is much slower than DSSS.
Fresnel Zone
An elliptical area on either side of the straight line of sight that must also be clear
for a long-range wireless network to work.
Full-Duplex
A communications circuit or system designed to simultaneously transmit and
receive two different streams of data. Telephones are an example of a full-duplex
communication system. Both parties on a telephone conversation can talk and
listen at the same time. If both talk at the same time, their two signals are not
corrupted.

network.
Gateway
In wireless terms, a gateway is an access point with additional software
capabilities such as providing NAT and DHCP.
Guard Interval (GI)
An interval of time between data packet transmissions. The guard interval time
for 802.11a/b/g systems is fixed at 800 microseconds. 802.11n devices can also
use a 400 microsecond guard interval, falling back to 800 microseconds if
excessive data corruption is detected.
H
Half-Duplex
A communications circuit or system designed to transmit and receive data, but
not both simultaneously. CB or walkie-talkie radios are an example of a half-
duplex communication system. Either parties on a radio conversation may talk or
listen; but both cannot talk at the same time without corrupting each other's
signal. If one operator is "talking", the other must be "listening" to have
successful communication.
Hz
Hertz. The international unit for measuring frequency equivalent to the older unit
of cycles per second. One megahertz (MHz) is one million hertz. One gigahertz
(GHz) is one billion hertz. The standard US electrical power frequency is 60 Hz.
802.11a devices operate in the 5 GHz band; 802.11b and g devices operate in
the 2.4 GHz band.
I
IEEE
Institute of Electrical and Electronics Engineers, Inc. IEEE is a professional
organization with members in over 175 countries and is an authority in technical
areas such as computer engineering and telecommunications. IEEE developed
the 802.11 specifications.
IP Address
A 32-bit identification number for each node on an Internet Protocol network.
These addresses are represented as four sets of 8-bit numbers (numbers from 0
to 255), separated by periods ("dots").
Networks using the TCP/IP Protocol route messages based on the IP address of
the destination. Each number can be 0 to 255. For example, 192.168.0.100 could
be an IP address. Each node on the network must have a unique IP address.

MIC
Message Integrity Check. One of the elements added to the TKIP standard. A
"signature" is added by each radio on each packet it transmits. The signature is
based on the data in the packet, a 64-bit value (key) and the MAC address of the
sender. The MIC allows the receiving radio to verify (check) that the data is not
forged.
MIMO
Multiple Input Multiple Output refers to using multiple antennas in a Wi-Fi device
to improve performance and throughput. MIMO technology takes advantage of a
characteristic called multipath, which occurs when a radio transmission starts out
at Point A and the reflects off or passes through surfaces or objects before
arriving, via multiple paths, at Point B. MIMO technology uses multiple antennas
to collect and organize signals arriving via these paths.
Modbus
The Modbus protocol provides the internal standard that the MODICON®
controllers use for parsing messages. During communications on a Modbus
network, the protocol determines how each controller will know its device
address, recognize a message addressed to it, determine the kind of action to be
taken, and extract any data or other information contained in the message. If a
reply is required, the controller will construct the reply message and send it using
Modbus protocol.
Modem
Stands for MODulator-DEModulator, a device that converts digital signals to
analog signals and vice-versa. Analog signals can be transmitted over
communications links such as telephone lines.
N
Network
A series of stations or nodes connected by some type of communication medium.
A network may consist of a single link or multiple links.
Node
An address or software location on the network.
Non-Occupancy Period
The time during which a radio cannot return to a frequency where radar was
detected. This time is typically 30 minutes. Typically a radio will not return to a
channel where radar was previously detected unless absolutely necessary.
Null Modem Cable
A specialty cross-communication cable with female connectors on each end used
for direct connection between devices when no modems are present. Commonly
used as a quick and inexpensive way to transfer files between two PCs without
installing a dedicated network card in each PC.

P
Panel Antenna
An antenna type that radiates in only a specific direction. Panel antennas are
commonly used for point-to-point situations. Sometimes called Patch antennas.
Parabolic Antenna
An antenna type that radiates a very narrow beam in a specific direction.
Parabolic antennas offer the highest gain for long-range point-to-point situations.
Peer-to-Peer Network
Each radio in a Peer-to-Peer network has the ability to receive data from - and
transmit data to - any other radio in the network.
Point-Multipoint (Broadcast) Network
A network type where a single master radio sends data to every remote radio in
the network. This is done repeatedly until every remote radio individually receives
and acknowledges the data. Each remote radio sends pending data to the
master radio that receives and acknowledges data sent from each remote. In this
configuration, there are multiple remote radios referenced to a single master
radio.
Point-Multipoint (Modbus) Network
A network with a single Master radio and multiple Remote radios. The devices
cabled to the radios communicate through the Modbus standard protocol. The
Master radio sends data to a Remote radio based on the Modbus address of the
Modbus device. The data is only sent to the single Remote device based on its
address. Each Remote radio sends its data only to the Master radio. The Master
and Remote radios acknowledge that data was received correctly.
Point-to-Multipoint
A wireless network in which one point (the access point) serves multiple other
points around it. Indoor wireless networks are all point-to-multipoint, and long-
range wireless networks that serve multiple clients usually employ either a single
omnidirectional antenna or multiple sector antennas.
Point-to-Point Network
A network consisting of a single Master radio and a single Remote radio. All data
from the Master is received and acknowledged by one Remote. All data from the
single Remote is received and acknowledged by the Master radio.

the signal from the TV station but cannot transmit back to the station.
Site Survey
A comprehensive facility study performed by network managers to ensure that
planned service levels will be met when a new wireless LAN, or additional WLAN
segments to an existing network are deployed. Site surveys are usually
performed by a radio frequency engineer and used by systems integrators to
identify the optimum placement of access points to ensure that planned levels of
service are met. Site surveys are sometimes conducted following the deployment
to ensure that the WLAN is achieving the necessary level of coverage. Site
surveys can also be used to detect rogue access points.
Spectrum
A range of electromagnetic frequencies.
Spread Spectrum
A form of wireless communication in which a signal’s frequency is deliberately
varied. This increases bandwidth and lessens the chances of interruption or
interception of the transmitted signal.
SSI

Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address
has two components: the network address, and the host (node or device)
address. For example, consider the IP address 150.215.017.009. Assuming this
is part of a Class B network (with a subnet mask of 255.255.0.0), the first two
numbers (150.215) represent the Class B network address, and the second two
numbers (017.009) identify a particular host on this network.
T
TKIP
Temporal Key Integrity Protocol. The wireless security encryption mechanism in
Wi-Fi Protected Access. TKIP uses a key hierarchy and key management
methodology that removes the predictability that intruders relied upon to exploit
the WEP key. In increases the size of the key from 40 to 128 bits and replaces
WEP’s single static key with keys that are dynamically generated and distributed
by an authentication server, providing some 500 trillion possible keys that can be
used on a given data packet. If also includes a Message Integrity Check (MIC),
designed to prevent the attacker from capturing data packets, altering them, and
resending them. By greatly expanding the size of keys, the number of keys in
use, and by creating an integrity checking mechanism, TKIP magnifies the
complexity and difficulty involved in decoding data on a Wi-Fi network. TKIP
greatly increases the strength and complexity of wireless encryption, making it far
more difficult (if not impossible) for a would-be intruder to break into a Wi-Fi
network.
U
UART
Universal Asynchronous Receiver/Transmitter
W
WAP
Wireless Application Protocol. A set of standards to enable wireless devices to
access internet services, such as the World Wide Web and email.
WDS
Wireless Distribution System. Enables access points to communicate with one
another in order to extend the range of a wireless networks. Used in 802.11g
based access points.
WEP
Wired-Equivalent Privacy protocol was specified in the IEEE 802.11 standard to
provide a WLAN with a minimal level of security and privacy comparable to a
typical wired LAN, using data encryption.
