Modern wireless devices utilize multiple antenna technologies including MIMO to improve the overall performance and available communication bandwidth in the same wireless spectrum. Traditional techniques for evaluating over-the-air radiated performance of wireless devices are not suitable for testing these technologies or evaluating the performance gain offered by the additional antennas. Instead, emerging techniques for testing these technologies rely on generating simulated multi-path environments that can replicate the interaction that the device under test would typically see in a real world environment. However, there are a range of different techniques vying for a standardized approach for industry certification of MIMO devices, each with its own pros and cons. This presentation will demonstrate the differences in a number of these concepts and provide a range of measured results showing the variation between good and bad wireless devices.
