Transmission channel between two body-worn terminals at 2.45 GHz and 5.8 GHz has been investigated. A series of data sets have been gathered in an office and anechoic environment for random realistic activities and several body orientations, and have been subjected to statistical analysis. The short-term and long-term fading components of the path gain envelope were separated and fitted to a number...
Interference between two wireless body area networks at 2.45GHz and 5.8GHz has been investigated. A series of data sets have been gathered in an indoor environment - standard office - for random realistic activities and body orientations, and have been subject to statistical analysis. It is clear that significant variations of the path gain can occur due to the changing positions and orientations...
This paper investigates the capacity of multiple-input multiple-output (MIMO) antenna arrays in different on-body area network channels. The two belt-head and belt-chest channels are compared, where, belt, refers to the transmitter's location, while the second part refers to the receiver location. The on-body channel model is constructed by using the Rice factor, the path loss, the shadowing deviation...
The topic of body centric communications can be divided into three domains: (1) Communications from the body surface to a nearby base station; (2) both antennas are on the body surface; and (3) at least one antenna may be in a medical implant within the body. These three domains have been called off-body, on-body and in-body, respectively. The classification serves to highlight some of the technical...
