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...
This paper introduces a new statistical method for combining vision and robot dynamics to generate trajectories to intercept a moving object. Previous methods only use information from the kinematics without considering the forces needed to move along the trajectory. Using robot dynamics allows extra measures, such as energy efficiency, to be optimised alongside maximising the likelihood of intercepting...
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...
In this paper the on-body radio channel is statistically analysed at 2.45 GHz and analytically and numerically modelled at the same frequency applying different techniques. The channel exhibits great variability due to body movements with path loss data behaving in different manors depending mainly on the freedom of the communication link between transmitting and receiving antenna. Simple and accurate...
