Testing mobile devices Over the Air (OTA) in its actual form factor allows device performance to be assessed with much greater accuracy than through conducted testing.  Spirent’s MIMO OTA Test solution is designed to test the MIMO performance of mobile devices under very realistic OTA conditions.

The Spirent solution addresses both important test areas of Reverberation and Anechoic Chamber configurations that are rapidly gaining prominence. Backed by Spirent’s world-class expertise in channel propagation modeling and simulation expertise, the solution offers flexibility and scalability to  support your MIMO test needs.

MIMO OTA Anechoic Chamber

Spirent’s MIMO OTA Anechoic Chamber solution supports the fully automated test capability for the latest CTIA MIMO OTA test plan. Allowing easy control over the number of paths, elevation spread and polarization, it can easily simulate key characteristics such as power delay profiles, base antenna polarization and Doppler effects. Read more about the importance of MIMO OTA testing and some key elements of CTIA’s test plan in Spirent’s Ensuring MIMO Device Performance with Over-the-Air Testing White Paper.

MIMO OTA Reverberation Chamber

Spirent’s MIMO OTA Reverberation Chamber solution creates realistic test environments by providing higher Dopplers as in vehicular and train fading environments, eNodeB antenna effects, imbalance,  high correlation cases, better control over delay spread, and AWGN to test interference-limited scenarios. It provides full support for operator and CTIA-mandated test plans for MIMO OTA mobile device performance that require Reverberation Chamber testing.
