Characterization On-Body Communication Dynamic Channel for Wireless Body Area Networks

The development and optimization of wireless system that detected for providing services for human require a comprehensive knowledge and accurate modeling for real and efficient using for radio channels. However, many core service applications for human are existing close to the human body which effected on nature of such wireless channels to be dynamic with its characteristics. Influences of the human body on the antennas and propagation channels have been deeply investigated in mobile communications, the wireless body area network (WBAN)for the mobile communication systems in operating frequency bands, communication ranges and environments and device size and on-body positions. These differences may change the channel characteristics and, hence, require new investigations of the WBAN channel. Therefore, this paper presents analyses forthe dynamic on-body area channelbased on real-time measurements of the time domain channel impulse response (CIR) at frequencies near the 800MHZ- and 3-GHz industrial, scientific, and medical (ISM) bands
