Abstract

This paper evaluates the interference impacts of an Ultra Wideband (UWB) device which is WiMedia compliant and has been deployed outdoor near a typical C-band satellite TV receiving antenna. The results of field measurements are compared with those derived by theoretical calculations. It is found that they are in good agreement with each other. When the UWB device was transmitting inside the main lobe of the dish antenna at a distance of less than 5m, the TV signal was seriously distorted and the picture and sound qualities were unacceptable. When it was moved away from the main lobe to side-by-side, the interference became negligible and the picture resumed normal. The aggregate effects of multiple UWB devices were also evaluated and noticeable. A UWB exclusion zone of 10m around a satellite dish antenna is proposed in this paper to allow the coexistence of both systems.
