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 shows channel models on path loss and power delay profile for wireless body area networks. These models were derived from measured channel transfer functions by using a vector network analyzer. The path loss models were obtained for the frequency bands of 430, 611, 953, 2450 MHz, and UWB band. A power delay profile model was given only for the UWB band because typical symbol duration of...
