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.
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.
Spirent Vertex Channel Emulator is a versatile platform that offers unprecedented scalability while supporting emulation of a large number of channel models. The chassis’ simple plug-and-play design is built to support a broad range of applications that require varying channel densities, from basic applications like two-channel SISO to complex, high channel density applications like MIMO OTA, carrier aggregation, and antenna array systems.
Allows scaling from 16 to 32 probes depending on test requirements.
Test both reverb and anechoic chamber configurations with minimal changes from a channel emulator setup perspective.
