1. A method of communication in a wireless network using ultra-wideband (UWB) spectrum, the wireless network comprising one or more simultaneously operating pico networks, the method comprising:

  • dividing the UWB spectrum into a plurality of frequency bands;

    forming at least four band groups each including at least three frequency bands, and at least one band group including at least two frequency bands;

    assigning at least one band group to each one of the pico networks;

    assigning at least one time frequency code to symbols associated with each one of the pico networks, 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;

    communicating data within each one of the pico networks using the assigned band groups according to the time frequency code, wherein each one of the band groups including at least three frequency bands further includes at least seven time frequency codes and the band group including at least two frequency bands further includes at least two time frequency codes.
