Simulation of broadband FWA networks in high-rise cities with linear antenna polarisation

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'...

Description
Summary: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.
