Abstract
In this article, an analysis of system loss and depolarization in body area networks (BANs) for body-toinfrastructure (B2I) communications based on a measurement campaign in the 5.8 GHz band in an indoor environment is performed. Measurements were performed with an off-body antenna transmitting linearly polarized signals and dual-polarized receiving antennas carried by the user on the body. A normal distribution with a mean of 2.0 dB and a standard deviation of 4.3 dB is found to be the best fit for modeling cross-polarization (XP) discrimination. The average correlation between the signals received by the orthogonally polarized antennas is below 0.5, showing that polarization diversity can be used. A model for the average value of the standard deviation of the XP discrimination ratio as a function of the transmitted polarization, the mobility of users, and the link dynamics is presented, together with a detailed description of the methodology being used.
