Spirent Communications has supplied its SR5500 Wireless Channel Emulator for testing beamforming capabilities of Time Domain-Long Term Evolution (TD-LTE) base stations to a major network equipment supplier for use at its laboratories in Shanghai, China.
TD-LTE uses a single shared frequency band for both uplink and downlink. Beamforming is an adaptive antenna technique used to maximize the performance of wireless systems. It typically makes use of eight antennas on the base station and two on the mobile device (8×2).
“Between ongoing work in China and probable deployment in India’s Broadband Wireless Access bands, TD-LTE may well be the wireless technology of choice for hundreds of millions of subscribers,” said Rob VanBrunt, vice president of Spirent’s Wireless business. “While the complexities of advanced antenna techniques require careful design and testing, the reward is very high data throughput capability. We look forward to seeing the results of the industry’s hard work, and are delighted to be a part of enabling it.”http://www.spirent.com/Solutions-Directory/SR5500.aspx
