Experimental Analysis of 3.5 GHz WiMAX 802.16e Interference in WiMedia-defined UWB Radio Transmissions

The interference produced by WiMAX mobile wireless transmissions operating in the 3.5 GHz band on a WiMedia-defined ultra-wideband (UWB) wireless link is experimentally analyzed in this paper. The investigation includes standard IEEE 802.16e WiMAX, and ECMA-368 UWB equipment as defined by the WiMedia alliance. A conventional meeting room scenario has been considered for the measurements. The experimental results indicate that WiMAX transmitters must be located at distances larger than 5 m from the UWB receiver to guarantee successful UWB communication.
