Abstract: A first wireless device (WAP1) belongs to a wireless communication system and is adapted to exchange information within at least a first band of frequencies. The method comprises detecting the eventual presence of at least one potential victim device (XDVC) operating within the first band of frequencies and reducing the interferences with said at least one potential victim device. Said first wireless device is provided with an antenna array (ANRR), and said detecting step comprises analyzing on said first wireless device the environment of the wireless device through said antenna array, and if said at least one potential victim device (XDVC) is detected, said interference reducing step comprises controlling the antenna array for steering the antenna beam towards an area located outside of the vicinity of said potential victim device for eventually exchanging information within said first band of frequencies with at least a second wireless device (WAP2) located in said area. The main embodiment uses Ultra Wide Band transmission known as UWB.
