1. An emulator for emulating a wireless network comprised of a plurality of wireless nodes, said emulator comprising: a controller for providing channel characteristic information; and a field programmable gate array (FPGA) for receiving said channel characteristic information and for receiving a plurality of signals from at least five wireless nodes, said FPGA for processing said signals according to said channel characteristic information from said controller to emulate signal propagation within each channel of a physical transmission medium resulting from all pairings of all wireless nodes.
