Prestigious discipline: MIMO All modern wireless communications standards utilize MIMO technology to increase the effective data through- put. A test generator must be able to simulate MIMO sce- narios exactly as they are present at the receive anten- nas of a receiver – even with complex MIMO receivers. This is where the multipath and fading capabilities of the R&S®SMW200A come into their own. The built-in base- band modules allow the simultaneous generation of up to eight signals. For MIMO scenarios, the signals from all transmit antennas – with antenna-specific coding – can be directly generated in a single instrument.
