Patent ID: 8189454

Claim:
A method of communication in a wireless network comprising one or more simultaneously operating pico networks, the method comprising: dividing the Ultra Wide Band (UWB) spectrum into a plurality of frequency bands, wherein a center frequency of each frequency band is given by: FC(N)=3432+528*(N−1) MHz, wherein FC(N) is the center frequency of band N; expressing each center frequency of each frequency band as a sum of powers of two factors of the smallest generated frequency; forming one or more band groups including one or more frequency bands from the plurality of frequency bands; assigning at least one band group to each one of the pico networks; excluding transmission in the frequency band located at 5.15 GHz to 5.85 GHz and introducing an offset of 264 MHz to frequency bands above the frequency band located at 5.15 GHz to 5.85 GHz; assigning at least one time frequency code to symbols associated with each one of the pico networks on a transmission-by-transmission basis, wherein the time frequency code represents one of a single frequency band and a pre-defined sequencing across all the frequency bands within the assigned band group; and communicating data within each one of the pico networks using the assigned band groups according to the time frequency code.
