Abstract:
1. A ultra wideband (UWB) wireless network comprising: a plurality of UWB wireless devices communicating over a plurality of UWB frequency bins extending over a UWB frequency range; at least one of said UWB wireless devices for determining a respective actual signal level associated with each UWB frequency bin, generating a do-not-use UWB frequency bin list by comparing each actual signal level with at least one interference threshold, The at least one interference threshold comprising a first interference threshold for when a frequency bin is not in use, and a second interference threshold higher than the first interference threshold for when a frequency bin is in use, and communicating the do-not-use UWB frequency bin list to at least one other UWB wireless device; said at least one UWB wireless device comprising a Fourier transform module for determining the actual signal levels.
