Simulation aids the development of WiMedia based radio’s as well as optimization and integration with other radios and follow on applications. The up to 1.6 GHz of BW needed to capture and analyze WiMedia based MB-OFDM requires an Oscilloscope for capture. Powerful Signal Analysis SW, can aid radio optimization, analysis and verification of operation to WiMedia spec. Receiver performance can be benchmarked and optimized through the use of a “golden radio”. Summary
