So assuming you live in a decent sized house/lot, should you really care about squatting all over the entire band? I mean sure I can see my neighbors wifi signals, but they are too weak for me to connect with them. So wouldn't mine be just as weak at their location, so why should I care about using the entire band? Aren't I really only using 2/3 of the band by going to 40Mhz, leaving an entire 20Mhz wide channel free for my neighbors AP to switch over to? I see substantial improvements in going from 20 to 40 Mhz from smartphone's that have 1X1 fixed antennas which is every smartphone. Going from 20 Mhz with a max theoretical of 72.2Mbps to 40 Mhz with a max theoretical of 150Mbps is a big difference. Especially when you typically only get half of the max theoretical speed.

This is why all of the pre-N performance enhancements for G were troublemakers if you had multiple wireless networks in the same area. You turn it on, and one of two things happen - you either wreck performance of everyone else on that band, or everyone else wrecks your performance. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
