Extension Channel
When the channel bandwidth is set to 20/40 MHz, the
extension channel provides a channel that is adjacent to
the primary channel but is not overlapped. The wireless
network acquires diploid bandwidth by this extension
channel, that is, 20MHz bandwidth.
Note:
IEEE 802.11n can bind two adjacent 20 MHz bandwidths
together to form a 40MHz bandwidth. Actually, the
40MHz bandwidth can act as two 20 MHz bandwidths.
One is the primary bandwidth and the other is the
