Parameter Description
Frequency Extension Configuration of this parameter is valid only if the
channel bandwidth is 40 MHz. If Upper Extension
Channel is selected, the radio automatically uses the
current channel (20MHz) as well as next upper
adjacent channel (20 MHz) for data transmission. If
Lower extension channel is selected, the radio
automatically uses the current channel (20MHz) as well
as lower adjacent channel (20 MHz) for data
transmission.
For example, if channel 36 is selected in 40 + mode,
the radio uses 36 as well as next upper adjacent
channel 40 also for data transmission, similarly if
channel 40 is used in 40- mode, the radio uses 40 as
well as the next lower adjacent channel 36 for data
transmission.
