MIMO Over-the-Air Testing

Traditional conducted-signal testing of mobile devices provides a more repeatable testing environment than testing with a radiated signal. However, the planned evolution of Fourth-Generation (4G) wireless technologies is critically dependent on Multiple-Input Multiple-Output (MIMO) antenna configurations, which promise significant data-rate increases based on moderate increases in complexity. Therefore, an over-the-air (OTA) testing methodology is needed to account for antenna behavior within the device evaluation.
