Ensuring MIMO Device Performance with Over-the-Air Testing
The complexity of mobile devices and networks continues to grow with the increasing application of technologies such as MIMO. Ideally, all facets of network performance and user experience that employ this innovation should be tested. Recognizing the importance, operators and manufacturers have worked with the industry to develop a test methodology that fully evaluates baseband modem performance and antenna design for MIMO operation. In view of this and similar development challenges, the CTIA developed a testing standard to determine the Over-the-Air (OTA) performance level of handsets that employ MIMO antennas.
