Ultra wideband (UWB) communication was evaluated within a closed space, with a view to partly replacing onboard data buses with wireless connections. Spatial distributions of UWB propagation in frequency (from 3.1 to 10.6 GHz), time domains and throughput with use of a radio absorber were derived from measured. It was also found that delay spreads can be suppressed by partially panelling a radio absorber...
Ultra wideband (UWB) propagation was measured and characterized within spacecrafts, with a view to partly replacing onboard data buses with wireless connections. Spatial distributions of UWB and narrowband propagation in frequency (from 3.1 to 10.6 GHz) and time domains were measured with a microwave vector network analyzer. While narrowband resulted in a number of dead spots (deep fading points)...
This paper reviews recent advances in ultra wideband (UWB) radio propagation measurements and modeling for wireless body area networks (WBAN) under a research project between Tokyo Denki University and National Institute of Information and Communications Technology of Japan. Several measurement campaigns and associated modeling have been carried out in either a radio anechoic chamber or a specific...
