An access point can be either a main, relay or remote base station. A main base station is typically connected to a
wired network via the Ethernet port. A relay base station relays data between main base stations and relay stations or
remote base stations with clients. A remote base station is the end point to accept connections from wireless clients
and pass data upwards to a network wirelessly.

Installation Considerations
There are a number of factors that can impact the range of wireless devices.
1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an ang le. The more
material the signal has to pass through the more signal you will lose.
2. Keep the number of obstructions to a minimum. Ea
Position the wireless devices in a manner that will minimize the amount of obstructions between them.
3. Building materials can have a large impact on your wireless signal. In an indoor environment, try to position the
wireless devices so that the signal passes through less dense material such as dry wall. Dense materials like metal,
solid wood, g
lass or even furniture may block or degrade the signal.
ch obstruction can reduce the range of a wireless device.
4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless adapter’s site survey tool
to determine the best antenna orientation for your wireless devices.
5. Interference from devices that produce RF (radio frequency) noise can also impact your signal. Position your wireless
devices away from anything th
6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz cordless phones or
other wireless remotes operating on the 2.4GHz frequency can potentially drop the wireless signal. Although the
phone may not be in use, the base can still transmit wireless signal. Move the phone’s base station as far away
possible from your wireless devices.
If you are still experiencing low or no signal consider repositioning the wireless devices or installing additional access
points. The use of higher gain antennas may also provide the necessary coverage depending on the environment.

Wireless Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per requirements properly, not
necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings for the system. Please click on
Wireless -> Advanced Setup and follow the below setting.
Short Slot : By default, it’s “Enable” for educing the slot time from the standard 20 microseconds to the 9
microsecond short slot time
Slot time is the amount of time a device waits after a collision before retransmitting a packet. Reducing the slot time
decreases the overall back-off, which increases throughput. Back-off, which is a multiple of the slot time, is the
random length of tim
channel the shorter slot time help manage shorter wait time to re-transmit f rom collision because of hidden wireless
clients or other causes. When collision sources can be removed sooner and other senders attempting to send are
listening the channel(CSMA/CA) the owner of the channel should continue ownership and finish their transmission
and release the channel. Then, follow
time. However, when long duration of existing collision sources and shorter slot time exist the owners might
experience subsequent collisions. When adj ustment to longer slot time can’t improve performance then RTS/CTS
could supplement and help improve performance.
Extra Slot Time : Slot time is in the range of 1~255 and set in unit of microsecond. The default value is 9
microsecond.
When you enable Short Slot and set Extra Slot time to “10”, the actual Slot Time=9+10 us.
When you disable Short Slot and set Extra Slot time to “10”, the actual Slot Time=20+10 us.
e a station waits before sending a packet on the LAN. For a sender and receiver own right of the
ing ownership of the channel will be sooner for the new pair due to shorter slot
㻝㻡
ACK Timeout : ACK timeout is in the range of 1~255 and set in unit of microsecond. The default value is 32
microsecond.
All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by receiving radio. The transmitter will
resend the original packet if correspondent ACK failed to arrive within specific time interval, also refer to as “ACK
Timeout”.
ACK Timeout is adjustable due to the fact tha
t distance between two radio links may vary in different deployment.
ACK Timeout makes significant influence in performance of long distance radio link. If ACK Timeout is set too short,
transmitter will start to “Resend” packet before ACK is received, and throughputs become low due to excessively high
re-transmission.
ACK Timeout is best determined by distance between the radios, data rate of average environment. The Timeout
value is calculated based on round-trip time of packet with a little tolerance, So, if experiencing re-transmissions or
poor performance the ACK Timeout could be made longer to accommodate.
Slot Time and ACK Timeout settings are for long distance links. It is important to tweak settings to achieve the
optimal result based on requirement.
Beacon Interval : Beacon Interval is in the range of 20~1024 and set in unit of millisecond. The default value is 100
msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame, called “Beacon”. Beacon is
broadcast to all the stations, provides the basic information of AP such as SSID, channel, encryption keys, signal
strength, time stamp, support data rate.
All the radio stations received bea
con recognizes the existence of such AP, and may proceed next actions if the
information from AP matches the requirement. Beacon is sent on a periodic basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated overhead, but that will
likely delay the association and roaming process beca use stations scanning for ava
ilable access points may miss the
beacons. You can decrease the beacon interval, which increases the rate of beacons. This will make the association
and roaming process very responsive; however, the network will incur additional overhead and throughput will go
down.
DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.
DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless stations, which support power
saving mode, when to wake up to receive multicast frame. DTIM is necessary and critical in wireless environment as
a mechanism to fulfill power-saving synchronization.
A DTIM interval is a count of the number of beacon
frames that must occur before the access point sends the
buffered multicast frames. For instance, if DTIM Interval is set to 3, then the Wi-Fi clients will expect to receive a
multicast frame after receiving three Beacon frame. The higher DTIM interval will help power saving and possibly
decrease wireless throughput in multicast applications.
㻝㻢
Fragment Threshold : The Fragment Threshold is in the range of 256~2346 byte. The default is 2346 byte.
Each Wi-Fi packet can be divided into smaller packets, marked with a sequential f ragment number and re-assemble
in the receiving ends. The purpose is to make a short frame, instead of long frame, transmitting by radio in a heavy
noisy environment. Because of sending smaller fr
obvious, the cons is the overhead for transmission. So, in a clean environment, higher fragment threshold can be an
option to increase throughput.
Fragmentation will be triggered by setting the Fragment Threshold, usually in Byte-length. Only when the frame size
is over the Threshold, fragmentation will take place automatically.
RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347 byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible collisions due to hidden wireless
clients. RTS in AP will be enabled automatically if the packet size is larger than the Threshold value. By default, RTS
is disabled in a normal environment supports non-jumbo frames.
Short Preamble : By default, it’s “Enable”. To Disable is to use Long 128-bit Preamble Synchronization field.
The preamble is used to signal "here is a train of data coming" to the receiver. The short preamble provides 72-bit
Synchronization field to improve WLAN transmission efficiency with less overhead.
Tx Burst : By default, it’s “Enable”. To Disable is to deactivate Tx Burst.
With TX burst enabled, AP will send many packets in a burst, without collision detection and RTS/CTS for each packet. TX
Burst have better throughput but cause interference with other APs in channel.
Pkt_Aggregate : By default, it's “Enable”
ames, corruptions are much less likely to occur. The pros is
Increase efficiency by aggregating multiple packets of application data into a single transmission frame. In this way,
802.11n networks can send multiple data packets with the fixed overhead cost of just a single frame.
IEEE802.11H (DFS) : By default, it's “Disable”. To Enable is to use IEEE802.11H(DFS)
With DFS(Dynamic Frequency Selection) enabled, radio is operating on one of the following channels, the wireless
device uses DFS to monitor the operating frequency and switch to another frequency or reduce power as necessary:
DFS Channels
The maximum legal transmit power is gre
randomly selects a 5 GHz channel on which power is restricted, the wireless device automatically reduces transmit
power to comply with power limits for that channel in that regulatory domain.
52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140

The Channel 52-140 is DFS channel. If tuen on IEEE802.11H, AP Will have 60 sec to do
channel available check, and will not send beacon and can not be connect. When
WCB1200H2PX detect radar(5GHz) signal, the AP will switch channel and stop beacon
trasmit between 15 sec.
㻝㻣
WMM : By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.
When you enable WMM, the “Tx Burst” will be Disabled automatically by system.

time is determined.
9 CWmax : Maximum Contention Window. The value specified here in the Maximum Contention Window is
the upper limit (in milliseconds) for the doubling of the random back-off value. This doubling continues until

“Checkbox” indicates “No ACK”
When the no acknowledgment (No ACK) policy is used, the recipient does not acknowledge received
packets during wireless packet exchange. This policy is suitable in the environment where communication
quality is fine and interference is weak. While the No ACK policy helps improve transmission efficiency, it
can cause increased packet loss when comm unication quality deterior
ates. This is because when this policy
is used, a sender does not retransmit packets that have not been received by the recipient.
When the Normal ACK policy is used, the recipient acknowledges each received unicast packet.
