Improvements in or relating to radio propagation modelling.

摘要

There is provided a system and a method for determining a performance metric of a wireless system in a virtual environment, the wireless system comprising two or more antennas (104, 108) that are adapted to transmit and/or receive signals there between, at least one of the two or more antennas being adapted to occupy two or more positions within the virtual environment. A plurality of routes through the virtual environment is generated, each route comprising a plurality of points in the virtual environment. A channel modelling module obtains both geographical topography data and Long-term Evolution (LTE) base station data relating to each of the plurality of points. At each of the plurality of points a characteristic of a signal produced by at least one of the antennas and received by another is emulated using data outputted from the channel modelling module. A plurality of performance parameters of the wireless system is determined in dependence on the emulated characteristics andan evaluation of each performance parameter is performed to determine the performance metric for the wireless system. The advantage of the invention is the saving of time and resources saved by not having to perform physical vehicle drive testing.
