Four channels, not three, for Wi-Fi networks!
Forget what you've been told, says the maker of PocketWINC
Over the last few years, it has been generally accepted that, although there are 11 channels for 802.11b or 802.11g networks, only three (1, 6 and 11) can be used if there is overlap between cells, because the signals interfere.
This White Paper describes how four non-overlapping channels, instead of the traditional three channels, can be used in an 802.11 network. This technology provides greater bandwidth in high density environments.
