Re: [BAWUG] beacon frames and channels

[William Arbaugh]

Actually, we've noticed that at least one vendor transmits beacons on 
adjacent channels to reduce the probe times. The idea is that the STA 
probes or listens to channel N and sees a beacon for channel N+1. No 
need to probe or listen on channel N+1 now.

One other possibility is that the receiver is near to a very high
powered AP and there is enough energy in the signal to recover it far
from its transmitted channel.  This can be easily demonstrated with a
Cisco 1200 AP, transmitting at full power (100mW) on channel 6.  Within
about 20 feet, the Beacons from this AP can be correctly received on 
all
11 802.11b channels.

Nope... Perhaps you have setup your AP to 'Search for best channel' and
it
is moving itself around the the lower utilization channel on a regular
basis?

Should an AP be broadcasting beacon frames on a channel other than the
one it's radio has been configured to use? For example, if my radio is
set to use channel 1, should I see beacon frames from that radio on
channel 11?
