B/G Protection
Mode Default: Auto. You can select the other options including On and Off. The B/G
protection technology is CTS-To-Self. It will try to reserve the throughput for
11g clients from 11b clients connecting to the device as AP mode.
Beacon Interval Beacons are the packets sending by Access point to synchronize the wireless
network. The beacon interval is the time interval between beacons sending by
this unit in AP or AP+WDS operation. The default and recommended beacon
interval is 100 milliseconds.
Data Beacon
Rate(DTM) This is the Delivery Traffic Indication Map. It is used to alert the clients that
multicast and broadcast packets buffered at the AP will be transmitted
immediately after the transmission of this beacon frame. You can change the
value from 1 to 255. The AP will check the buffered data according to this value.
For example, selecting “1” means to check the buffered data at every beacon.
Fragment
Threshold The fragmentation threshold determines the size at which packets are
fragmented (sent as several pieces instead of as one block). Use a low setting in
areas where communication is poor or where there is a great deal of radio
interference. This function will help you to improve the network performance.
RTS Threshold The RTS threshold determines the packet size at which the radio issues a request
to send (RTS) before sending the packet. A low RTS Threshold setting can be
useful in areas where many client devices are associating with the device, or in
areas where the clients are far apart and can detect only the device and not each
other. You can enter a setting ranging from 0 to 2347 bytes.
TX Power The default TX power is 100%. In case of shortening the distance and the coverage
of the wireless network, input a smaller value to reduce the radio transmission
power. For example, input 80 to apply 80% Tx power.
Short Preamble Default: Disable. It is a performance parameter for 802.11 b/g mode and not
supported by some of very early stage of 802.11b station cards. If there is no such
kind of stations associated to this AP, you can enable this function.
Short Slot It is used to shorten the communication time between this AP and station.
TX Burst The device will try to send a serial of packages with single ACK reply from the
clients. Enable this function to apply it.

5. FREQUENTLY ASKED QUESTIONS (FAQ)
Enter topic text here.
5.1 What and how to find my PC’s IP and MAC address?
IP address is the identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP
protocol route messages based on the IP address of the destination. The format of an IP address is a
32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255.
For example, 191.168.1.254 could be an IP address
The MAC (Media Access Control) address is your computer's unique hardware number. (On an
Ethernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet from your
computer (or host as the Internet protocol thinks of it), a correspondence table relates your IP address to
your computer's physical (MAC) address on the LAN.
To find your PC’s IP and MAC address,
9 Open the Command program in the Microsoft Windows.
9 Type in “ipconfig /all”, then press the Enter button.
9 Your PC’s IP address is the one entitled IP Address and your PC’s MAC address is the one
entitled Physical Address.
5.2 What is Wireless LAN?
A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wired
connections to the user’s machine.
5.3 What are ISM bands?
ISM stands for Industrial, Scientific and Medical; radio frequency bands that the Federal
Communications Commission (FCC) authorized for wireless LANs. The ISM bands are located at 915
+/-13 MHz, 2450 +/-50 MHz and 5800 +/-75 MHz.
5.4 How does wireless networking work?
The 802.11 standard define two modes: infrastructure mode and ad hoc mode. In infrastructure mode,
the wireless network consists of at least one access point connected to the wired network infrastructure
and a set of wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended
Service Set (ESS) is a set of two or more BSSs forming a single sub-network. Since most corporate
WLANs require access to the wired LAN for services (file servers, printers, Internet links) they will
operate in infrastructure mode.
Example 1: wireless Infrastructure Mode
- 59 -
2.4G Outdoor Router
User Manual
Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) is simply a
set of 802.11 wireless stations that communicate directly with one another without using an access
point or any connection to a wired network. This mode is useful for quickly and easily setting up a
wireless network anywhere that a wireless infrastructure does not exist or is not required for services,
such as a hotel room, convention center, or airport, or where access to the wired network is barred
(such as for consultants at a client site).
Example 2: wireless Ad Hoc Mode
5.5 What is BSSID?
A six-byte address is that distinguish a particular a particular access point from others. Also know as
just SSID. Serve as a network ID or name.
5.6 What is ESSID?
The Extended Service Set ID (ESSID) is the name of the network you want to access. It is used to
identify different wireless networks.
5.7 What are potential factors that may causes interference?
Factors of interference:
2 Obstacles: walls, ceilings, furniture… etc.
2 Building Materials: metal door, aluminum studs.
2 Electrical devices: microwaves, monitors and electrical motors.
Solutions to overcome the interferences:
9 Minimizing the number of walls and ceilings.
9 Position the WLAN antenna for best reception.
9 Keep WLAN devices away from other electrical devices, eg: microwaves, monitors, electric
motors…etc.
9 Add additional WLAN Access Points if necessary.
5.8 What are the Open System and Shared Key authentications?
IEEE 802.11 supports two subtypes of network authentication services: open system and shared key.
Under open system authentication, any wireless station can request authentication. The station that
needs to authenticate with another wireless station sends an authentication management frame that
contains the identity of the sending station. The receiving station then returns a frame that indicates
whether it recognizes the sending station. Under shared key authentication, each wireless station is
assumed to have received a secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel.
5.9 What is WEP?
An option of IEEE 802.11 function is that offers frame transmission privacy similar to a wired network.
The Wired Equivalent Privacy generates secret shared encryption keys that both source and destination
stations can use to alert frame bits to avoid disclosure to eavesdroppers.
WEP relies on a secret key that is shared between a mobile station (e.g. a laptop with a wireless
Ethernet card) and an access point (i.e. a base station). The secret key is used to encrypt packets before
they are transmitted, and an integrity check is used to ensure that packets are not modified in transit.

2.4G Outdoor Router
User Manual
5.10 What is Fragment Threshold?
The proposed protocol uses the frame fragmentation mechanism defined in IEEE 802.11 to achieve
parallel transmissions. A large data frame is fragmented into several fragments each of size equal to
fragment threshold. By tuning the fragment threshold value, we can get varying fragment sizes. The
determination of an efficient fragment threshold is an important issue in this scheme. If the fragment
threshold is small, the overlap part of the master and parallel transmissions is large. This means the
spatial reuse ratio of parallel transmissions is high. In contrast, with a large fragment threshold, the
overlap is small and the spatial reuse ratio is low. However high fragment threshold leads to low
fragment overhead. Hence there is a trade-off between spatial re-use and fragment overhead.
Fragment threshold is the maximum packet size used for fragmentation. Packets larger than the size
programmed in this field will be fragmented.
If you find that your corrupted packets or asymmetric packet reception (all send packets, for example).
You may want to try lowering your fragmentation threshold. This will cause packets to be broken into
smaller fragments. These small fragments, if corrupted, can be resent faster than a larger fragment.
Fragmentation increases overhead, so you'll want to keep this value as close to the maximum value as
possible.
5.11 What is RTS (Request to Send) Threshold?
The RTS threshold is the packet size at which packet transmission is governed by the RTS/CTS
transaction. The IEEE 802.11-1997 standard allows for short packets to be transmitted without RTS/
CTS transactions. Each station can have a different RTS threshold. RTS/CTS is used when the data
packet size exceeds the defined RTS threshold. With the CSMA/CA transmission mechanism, the
transmitting station sends out an RTS packet to the receiving station, and waits for the receiving station
to send back a CTS (Clear to Send) packet before sending the actual packet data.
This setting is useful for networks with many clients. With many clients, and a high network load, there
will be many more collisions. By lowering the RTS threshold, there may be fewer collisions, and
performance should improve. Basically, with a faster RTS threshold, the system can recover from
problems faster. RTS packets consume valuable bandwidth, however, so setting this value too low will
limit performance.
5.12 What is Beacon Interval?
In addition to data frames that carry information from higher layers, 802.11 include management and
control frames that support data transfer. The beacon frame, which is a type of management frame,
provides the "heartbeat" of a wireless LAN, enabling stations to establish and maintain
communications in an orderly fashion.
Beacon Interval represents the amount of time between beacon transmissions. Before a station enters
power save mode, the station needs the beacon interval to know when to wake up to receive the beacon
(and learn whether there are buffered frames at the access point).
5.13 What is Preamble Type?
There are two preamble types defined in IEEE 802.11 specification. A long preamble basically gives
the decoder more time to process the preamble. All 802.11 devices support a long preamble. The short
preamble is designed to improve efficiency (for example, for VoIP systems). The difference between
the two is in the Synchronization field. The long preamble is 128 bits, and the short is 56 bits.
5.14 What is SSID Broadcast?
Broadcast of SSID is done in access points by the beacon. This announces your access point (including
various bits of information about it) to the wireless world around it. By disabling that feature, the SSID
configured in the client must match the SSID of the access point.
Some wireless devices don't work properly if SSID isn't broadcast (for example the D-link DWL-120
USB 802.11b adapter). Generally if your client hardware supports operation with SSID disabled, it's

User Manual
not a bad idea to run that way to enhance network security. However it's no replacement for WEP,
MAC filtering or other protections.
5.15 What is Wi-Fi Protected Access (WPA)?
Wi-Fi’s original security mechanism, Wired Equivalent Privacy (WEP), has been viewed as insufficient
for securing confidential business communications. A longer-term solution, the IEEE 802.11i standard,
is under development. However, since the IEEE 802.11i standard is not expected to be published until
the end of 2003, several members of the WI-Fi Alliance teamed up with members of the IEEE 802.11i
task group to develop a significant near-term enhancement to Wi-Fi security. Together, this team
developed Wi-Fi Protected Access.
To upgrade a WLAN network to support WPA, Access Points will require a WPA software upgrade.
Clients will require a software upgrade for the network interface card, and possibly a software update
for the operating system. For enterprise networks, an authentication server, typically one that supports
RADIUS and the selected EAP authentication protocol, will be added to the network.
5.16 What is WPA2?
It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11
standard.
5.17 What is 802.1x Authentication?
802.1x is a framework for authenticated MAC-level access control, defines Extensible Authentication
Protocol (EAP) over LANs (WAPOL). The standard encapsulates and leverages much of EAP, which
was defined for dial-up authentication with Point-to-Point Protocol in RFC 2284.
Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL messages that convey the
shared key information critical for wireless security.
5.18 What is Temporal Key Integrity Protocol (TKIP)?
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption
standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol,
which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a message
integrity check and a re-keying mechanism, thus fixing the flaws of WEP.
5.19 What is Advanced Encryption Standard (AES)?
Security issues are a major concern for wireless LANs, AES is the U.S. government’s next-generation
cryptography algorithm, which will replace DES and 3DES.
5.20 What is Inter-Access Point Protocol (IAPP)?
The IEEE 802.11f Inter-Access Point Protocol (IAPP) supports Access Point Vendor interoperability,
enabling roaming of 802.11 Stations within IP subnet.
IAPP defines messages and data to be exchanged between Access Points and between the IAPP and
high layer management entities to support roaming. The IAPP protocol uses TCP for inter-Access Point
communication and UDP for RADIUS request/response exchanges. It also uses Layer 2 frames to
update the forwarding tables of Layer 2 devices.
5.21 What is Wireless Distribution System (WDS)?
The Wireless Distribution System feature allows WLAN AP to talk directly to other APs via wireless
channel, like the wireless bridge or repeater service.
5.22 What is Universal Plug and Play (uPNP)?
UPnP is an open networking architecture that consists of services, devices, and control points. The

ultimate goal is to allow data communication among all UPnP devices regardless of media, operating
system, programming language, and wired/wireless connection.
5.23 What is Maximum Transmission Unit (MTU) Size?
Maximum Transmission Unit (MTU) indicates the network stack of any packet is larger than this value
will be fragmented before the transmission. During the PPP negotiation, the peer of the PPP connection
will indicate its MRU and will be accepted. The actual MTU of the PPP connection will be set to the
smaller one of MTU and the peer’s MRU.
5.24 What is Clone MAC Address?
Clone MAC address is designed for your special application that request the clients to register to a
server machine with one identified MAC address. Since that all the clients will communicate outside
world through the WLAN Broadband Router, so have the cloned MAC address set on the WLAN
Broadband Router will solve the issue.
5.25 What is DDNS?
DDNS is the abbreviation of Dynamic Domain Name Server. It is designed for user owned the DNS
server with dynamic WAN IP address.
5.26 What is NTP Client?
NTP client is designed for fetching the current timestamp from internet via Network Time protocol.
User can specify time zone, NTP server IP address.
5.27 What is VPN?
VPN is the abbreviation of Virtual Private Network. It is designed for creating point-to point private
link via shared or public network.
5.28 What is IPSEC?
IPSEC is the abbreviation of IP Security. It is used to transferring data securely under VPN.
5.29 What is WLAN Block Relay between Clients?
An Infrastructure Basic Service Set is a BSS with a component called an Access Point (AP). The access
point provides a local relay function for the BSS. All stations in the BSS communicate with the access
point and no longer communicate directly. All frames are relayed between stations by the access point.
This local relay function effectively doubles the range of the IBSS.
5.30 What is WMM?
WMM is based on a subset of the IEEE 802.11e WLAN QoS draft standard. WMM adds prioritized
capabilities to Wi-Fi networks and optimizes their performance when multiple concurring applications,
each with different latency and throughput requirements, compete for network resources. By using
WMM, end-user satisfaction is maintained in a wider variety of environments and traffic conditions.
WMM makes it possible for home network users and enterprise network managers to decide which
data streams are most important and assign them a higher traffic priority.
5.31 What is WLAN ACK TIMEOUT?
ACK frame has to receive ACK timeout frame. If remote does not receive in specified period, it will be
retransmitted.
5.32 What is Modulation Coding Scheme (MCS)?
MCS is Wireless link data rate for 802.11n. The throughput/range performance of an AP will depend on
its implementation of coding schemes. MCS includes variables such as the number of spatial streams,

modulation, and the data rate on each stream. Radios establishing and maintaining a link must
automatically negotiate the optimum MCS based on channel conditions and then continuously adjust
the selection of MCS as conditions change due to interference, motion, fading, and other events.
5.33 What is Frame Aggregation?
Every 802.11 packet, no matter how small, has a fixed amount of overhead associated with it. Frame
Aggregation combines multiple smaller packets together to form one larger packet. The larger packet
can be sent without the overhead of the individual packets. This technique helps improve the efficiency
of the 802.11n radio allowing more end user data to be sent in a given time.
5.34 What is Guard Intervals (GI)?
A GI is a period of time between symbol transmission that allows reflections (from multipath) from the
previous data transmission to settle before transmitting a new symbol. The 802.11n draft specifies two
guard intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is optional for transmit and
receive. The purpose of a guard interval is to introduce immunity to propagation delays, echoes, and
reflections to which digital data is normally very sensitive.
