This paper presents the characterization of the path loss in ultrawide band body area networks. A Measurement campaign was performed in the anechoic chamber and in an indoor environment for comparison. The propagation along the front part of the body was analyzed, and the effect of the body movements on the signal strength was investigated. The results demonstrated that the normal distribution provides...
This letter reports the statistical characterization and modeling of the indoor radio channel for a mobile wireless personal area network operating at 868 MHz. Line of sight (LOS) and non-LOS conditions were considered for three environments: anechoic chamber, open office area, and hallway. Overall, the Nakagami-m cdf beast described fading for bodyworn operation in 60% of all measured channels in...
