This letter presents an experimental methodology for bit-error-rate over-the-air testing to evaluate the communication quality of body area network (BAN) antennas. We proposed a dual-discrete control method to detect an instantaneous bit error rate (BER) using a fading emulator with a dynamic human phantom. Particular emphasis is placed on how to implement the proposed method while simultaneously...
This paper presents a measurement method on the Bit-Error-Rate (BER) Over-The-Air (OTA) Testing of FSK signals for BAN antennas. The human body shadowing effects when a human walks in a multiple radio wave propagation environment are performed by a developed fading emulator with a dynamic phantom. The results show that the shadowing effect caused by the arm in a Rayleigh fading propagation environment...
This paper presents a preliminary investigation on the body proximity cross-polarization properties considering human walking motion for the applications to BAN (Body Area Network) On-Body wireless communication systems. Firstly, a novel concept of the BP-XPR (Body Proximity Cross-Polarization Power Ratio) in on-body channel is defined, which has been quantified based on relative on-body antenna locations...
This paper presents a new methodology of an Over-the-Air (OTA) testing using an arm-swinging dynamic phantom applied to wireless Body Area Network (BAN) systems. The phantom has unique features, in that swinging of the right and left arms and the direction and speed of swing can be controlled independently, leading to excellent capability for replicating the variety of natural walking and running...
