Channel modelling and characterisation for wireless body area networks
Investigators: Simon Cotton & William Scanlon
The main aim of this project was to investigate the propagation aspects of wearable communications systems for a range of environments.
The work featured a narrowband wearable channel measurement system that can make synchronised RSSI measurements as a user moves naturally throughtout an indoor or outdoor environment.
The work involved both on-body and off-body links at 868 MHz and 2.45 GHz and considered single antenna and multiple
antenna systems. The results obtained have considered diversity gain and channel fading statistics.
