Spirent Communications said a major network equipment manufacturer has installed its Spirent SR5500 Wireless Channel Emulator for testing beamforming capabilities of TD-LTE base stations at its laboratories in Shanghai, China.
Unlike the Frequency-Domain implementation of LTE currently being deployed in North America and Europe, TD-LTE uses a single shared frequency band for both uplink and downlink.
Spirent’s SR5500 is used to simplify and accelerate the testing associated with complex beamforming implementations.
The SR5500 is a modular system which creates realistic synchronized radio paths by affecting a transmitted radio signal in the same way as a live environment.
