Test and Simulation of Radio Propagation Loss in Complex Environments

The determinative method of radio propagation characteristics forecast provides an effective and accurate way for propagation loss computation which is needed for in-door test of communication equipment.Out-door field test method and simulation method are both adopted to compute the propagation loss of a certain communication link.The results of field test and in-door simulation as well as error analysis are presented to show that the determinative method of radio propagation characteristics forecast based on ray-tracing algorithm is feasible for communication link propagation loss computation in complex environments.
