Abstract:
1. A method of managing operation of a first Ultra Wideband (UWB) wireless device belonging to a wireless UWB communication system and adapted to exchange information within at least a first band of frequencies, the method comprising: detecting a presence of at least one potential victim device operating within the first band of frequencies and reducing the interference with the at least one potential victim device; providing the first UWB wireless device with an antenna array; providing the first UWB wireless device with a plurality of transceiving chains coupled to the antenna array, with each transceiving chain being able to individually control the antenna array for steering its own signals toward a direction; the detecting comprising analyzing on the first UWB wireless device an environment of the first UWB wireless device using the antenna array; and if the at least one potential victim device is detected, the interference reducing comprising controlling the antenna array for steering an antenna beam toward an area located outside a vicinity of the at least one potential victim device for exchanging information within the first band of frequencies with at least one second UWB wireless device located in the area, and with the antenna array being controlled through at least two of the plurality of transceiver chains for simultaneously transmitting two signals having two different bands of frequencies in two respectively selected directions.
