1 edit | I run a mixed N and G environment - I have 2 G routers, and a Dlink 655, all within 10 feet of each other.
The Gs are not degraded. At the same location, 25' and 2 drywalls from the AP, a G based card got 60%, "good" signal and 12-18Mb/sec throughput. Swapping it for an N card signal is 92-96%, "Excellent" - speed is 240-300 at the link layer, and throughput is 30-40Mb/sec (as measured by iperf) across the wireless link.
Range out to the farthest unit is only 50' and one exterior wall + 2 drywall... G is poor, 20-30%, N is Good to Very Good, 70-80%, speeds are 20-25Mbit for N, and 8-10Mbit for G. (Note G was there before, tested G before and after installing N, G performance identical - still use several G units in the house talking to a Linksys G router, without issues. N is used for higher speed HD Media streaming.)
I've done the site survey, there are 4 other G networks at 10-20% signal, and one at about 50% - I put my three networks such that they don't overlap each other (much)
My results in a residential single family home (but tightly packed homes!) have been pretty positive - more throughput (not 20X, but a solid 10-20Mbit more) and about the same signal boost as moving everything halfway closer to the AP.
This is all draft 2.0 stuff, perhaps thats better then the first wave of attempts?
