Two-Channel Method for OTA Performance Measurements of MIMO-enabled Devices

Modern wireless communication technologies such as LTE, HSPA+ and WiMAX include the MIMO technology to achieve increased speed for data transmission. Existing Over-the-air (OTA) test systems need to be upgraded to support MIMO as well. This white paper summarizes a straightforward and cost-effective approach to verify the OTA performance of MIMO-enabled devices. Measurements of receiver sensitivity and throughput are evaluated with statistical metrics.
