Re: I like and dislike

Only because they're tiny and non-contiguous blocks. I seriously had to ask around as to whether they were big enough to be useful.

A single 802.11b channel uses more spectrum than we're talking about here.

If the spectrum is 25 MHz and it lies between 2155 and 2180 MHz, how can it be non-contiguous?

802.11[b] is spread spectrum.

Looks like you're right -- in June 2008 it became 2155-2180 MHz -- maybe it was AWS-2 that I was thinking of.

802.11b channel centers are 5 MHz apart but the signals are 20 MHz wide ... looks like this:
