Patent ID: 7272358

Claim:
A wireless network operating in the ISM frequency band between 2400 MHz and 2483.5 MHz, comprising: a plurality of access points to which wireless devices communicate; each access point programmable to a first channelization scheme and a second channelization scheme, wherein the first channelization scheme comprises a three channel channelization scheme in which no more than three access points operate within range of each other; and wherein for the second channelization scheme, each access point can be set to a carrier frequency selected from a group of four frequencies consisting of a first frequency, a second frequency, a third frequency and a fourth frequency, wherein, for the second channelization scheme, the first frequency is between 2406.938 MHz and 2407.062 MHz, inclusive, the second frequency is between 2426.938 MHz and 2427.062 MHz, inclusive, the third frequency is between 2446.938 MHz and 2447.062 MHz, inclusive, and the fourth frequency is between 2466.938 MHz and 2467.062 MHz, inclusive; wherein the wireless network is IEEE 802.11 based network; wherein, for the second channelization scheme, four access points can operate within range of each other.
