Channel Width Select the channel width of this device. 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). According to IEEE
802.11n standard, using a channel width of 40 MHz can increase wireless
throughput. However, you may need 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/ Select appropriate channel used by this device to improve wireless
Frequency
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.
CPE210/CPE220/WBS210 is a device with a frequency of 2.4GHz and
CPE510/CPE610/WBS510 has a frequency of 5GHz. 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.
