Abstract
A dynamic RF matrix emulator uses digital switching to emulate the switching behavior of hundreds of wireless terminals. The emulator includes a switching matrix with channels formed between terminal pairs, digital front ends for coupling terminals digitally to the switching matrix, and a channel database having entries representing attenuation values which can be changed in time, the attenuation values correlated with movement of vehicles provided by a traffic simulator. Channel behavior is defined by temporal attenuation values obtained from the database. The digital switching is controlled through a digital communication protocol.
