Channel Width
Select the channel width of this device. To check what channel width your
device supports, refer to the actual web interface.
For certain devices, options include 5 MHz, 10 MHz, 20 MHz, 40 MHz and
20/40 MHz (the device automatically selects 40 MHz, and 20 MHz will be
used if 40 MHz is not available).
For certain devices, options include 20 MHz, 40 MHz, 80 MHz and 20/40/80
MHz (the device automatically selects 80 MHz, and 40 MHz will be used if 80
MHz is not available, and so on).
According to IEEE 802.11n standard, using a wider channel can increase
wireless throughput. However, you may need to choose lower bandwidth
due to the following reasons:
• To increase the available number of channels within the limited total
bandwidth.
• To avoid interference from overlapping channels occupied by other
devices in the environment.
• Lower bandwidth can concentrate higher transmit power, increasing
stability of wireless links over long distances.
• In Client / AP Client Router / Repeater / Bridge Mode, the device should
have the same channel width as the root AP.
• In Access Point / AP Router / Repeater / Bridge Mode, select the channel
width which your clients support.
Max TX Rate
Set the maximum transmit data rate.
Channel/
Frequency
Select appropriate channel used by this device to improve wireless
performance. 1/2412 MHz refers to Channel 1 and the frequency is 2412
MHz. This setting is only available in Access Point Mode and AP Router
Mode. We highly recommend that you use the Spectrum Analysis tool to
select a proper channel.
Antenna
Select your antenna from the list.
Antenna Gain
Antenna Gain is only available in WBS products. Enter the antenna gain
value according to the antennas and the value ranges from 0 to 30dBi. It
can work together with the transmit power to improve the transmit signal
quality.
EIRP Limit
This option should remain enabled. With EIRP Limit enabled, the transmit
power is restricted so that the EIRP (Effecitive Isotropic Radiated Power) of
the device is kept below the amount which is allowed in the selected region.
