Re: [Aironet] Search for less congested channels

[Peter K. L. <pk...@du...>]

a quick question, how do you detect rate shift change?

meaning, how does the ap tell the clients to slow down?  is it in
management frames?  if so, is it part of the capabilities header as
specified in 802.11b protocol where the element contains supported
rates?

Or is that field just listing hardware supported rates, not the current
working rate?

Thanks,
