WiFi gets another usable channel
The CTO of a company called Cirond has released a whitepaper arguing that WiFi access points that overlap coverage can use four channels, instead of the traditional three. This opens up a new world of possibilties for packing 802.11b points more densely, on channels 1, 4, 8 and 11. The insight relies on the idea that by arraying access points on multiple storeys of a building, adding a third dimension to the overlap, you can minimize interference, even on channels that nominally overlap.
