C) Regulatory Domain/Channels
.
Channels
– selecting the channel that the access point will use to transmit and receive information. If
one channel is defined, it acts as the default channel. Channels list will vary depending on selected
regulatory domain and selected band. Multiple frequency channels are used to avoid interference
between two radios of this AP, and between nearby access points. If you wish to operate more than
one access point in the overlapping coverage areas, we recommend a distance of at least four
channels between the chosen channels. For example, for three Access Points in close proximity
choose channels 1, 6 and 11 for 11b/g or channels 36, 40 and 64 for 11a.
Band
– working band on the working radio.
Five bands are supplied: 5GHz (11a), 2.4GHz (Mixed 11g), 2.4GHz (11g only), 2.4GHz (Mixed
11g WiFi) and 2.4GHz (11g only WiFi).
If 2.4GHz (Mixed 11g) or 2.4GHz (11g only) is selected, the radio will work on 2.4GHz for the
better performance. 2.4GHz (11g only) mode only allows 11g client access. 2.4GHz (Mixed 11g)
mode allows 11b/11g client access.
2.4GHz (Mixed 11g WiFi) or 2.4GHz (11g only WiFi) can make sure to be compatible with Wi-Fi.
If 5GHz (11a) is selected, the radio will work on 5GHz 11a mode.
Output Power
- indicating output power of the RF card in dBm, antenna gain is not included.
Total Output Power (EIRP) = Antenna Gain + RF card output power
The range of the EIRP varies with channel and regulatory domain.
Antenna
– showing the type of Antenna.
RTS Threshold
– when set, this settings specifies the maximum packet size beyond the RTS/CTS
mechanism invoked. The value range of this is [0 …2347]. The default is 2347, which means that RTS
is disabled.
Enable DCA
– Enabling or Disabling DCA service. DCA can help choosing the best working channel
automatically. And static channel selection will be forbidden if DCA is enabled.
DCA(Dynamic Channel Allocation) solution automatically selects the optimal operational frequency
channel during power up and periodically monitors the environment and adjusts for the best
operational frequency channel.
DCA service is available only under 2.4GHz band.
DCA threshold
– specifying the value (in minutes) of DCA threshold. This threshold is used to judge
if there is no wireless user connected during this time. And if yes, BW1251 will monitor the
environment and adjust channel for the best operational one.
