ABSTRACT:
A four channel wireless network channelization scheme is described that is particularly usable in the ISM frequency band between 2400 MHz and 2483.5 MHz. The preferred channelization scheme permits access points to be set at one of four frequencies in the ISM band, not three as taught by the IEEE 802.11b standard. This channelization scheme takes advantage of the fact that only 20 MHz is typically needed between adjacent access point channels, not 25 MHz as is taught by the 802.11b standard. With four channels to choose from, a higher density of access points can be located thereby accommodating a higher density of users. The four channels preferably are 2407, 2427, 2447 and 2467 MHz. With this selection of channel frequencies and given the current FCC regulations, all four channels can be used to transmit an equal amount of power.
