A field trial to analysis coexistence performance between WiMedia-defined UWB and WiMAX 802.16e link in a short-range communications scenarios as in personal are networks is herein reported. The experimental analysis addresses the coexistence between OFDM-UWB and WiMAX 802.16e in both directions: WiMAX over UWB and viceversa. Relevant protection margins are derived from the experimental results. The measurements indicate that a WiMAX link with 10 and 20 MHz bandwidth achieves successful communication even if there is a UWB interferer at 2.5 m distance. In the case of 5 MHz BW WiMAX, successful communication can be guaranteed up to 5 m with a UWB interferer at 2.5 m vicinity. UWB devices operating in TFC 1 can perform a successful link up to 2 m with a WiMAX 10 MHz interferer located at 10 m close area. These experimental results indicate that UWB systems have to perform cognitive detect-and-avoid radio issues to guarantee a successful transmission in presence of WiMAX.
