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

802.11[b] is spread spectrum.]]> http://www.dslreports.com/forum/remark,21625431 Tue, 23 Dec 2008 08:15:48 EDT http://www.dslreports.com/forum/remark,21622928 funchords : 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.]]> http://www.dslreports.com/forum/remark,21622928 Mon, 22 Dec 2008 18:29:57 EDT http://www.dslreports.com/forum/remark,21622913 DavePR : How do you figure these frequencies are "the dregs"? Sirius and XM seem happy enough living in the neighborhood.]]> http://www.dslreports.com/forum/remark,21622913 Mon, 22 Dec 2008 18:26:54 EDT http://www.dslreports.com/forum/remark,21621164 funchords : This is a plan that tests me --

I don't like the idea of a plan that offers 100% nationwide coverage or it gets pulled in 10 years. You know what's going to happen -- what we in technology call the "ninety-ninety" rule. And then what? (Oh yeah, and I hate the filters and I have doubts that what we'll get will be "broadband" even in current sense, let alone 10-years-from-now sense.)

That said, I like the out-of-the-box thinking here. These frequencies are dregs. If not auctioned, they won't be used. This is like the 3M R&D experiment that led to post-it notes. It won't hurt anything to try it, and even if we end up with something completely different than expected, it'll be interesting to see what we get.

I think the Commissioners have enough info -- if they can shut the corporate lobbyists off and put their jurist hats on, I won't decry a decision either way too much.
