Abstract :
A ray-tracing algorithm is used to simulate broadband radio propagation at 3.5 GHz for a FWA network in a high-rise city environment. Both coverage and uplink interference are investigated, with linear antenna polarisation. It is shown that some rooftop locations are unsuitable positions for SU´s, due to the existence of single or multiple-bounce reflected rays causing uplink interference. It is usually possible to find a SU position just a few metres away on the same rooftop which gives much lower uplink interference.
