Spirent Communications has announced that several companies has are now using its VR5 HD Spatial Channel emulator for advanced MIMO beamforming testing. VR5 emulates radio conditions of real-world networks and helps identify issues with antenna design before deployment. Here is the link for Spirent’s VR5. Radio test equipments such as VR5 play key role in LTE product development projects such as 4G LTE modules, where simulated networks are needed for both module and host level testing.
