ZTE announced pre-commercial field testing of a next gen base station leveraging Massive MIMO (multiple input multiple output) that sets new records in single-carrier transmission capacity and spectral efficiency.

Based on ZTE’s self-developed baseband processor chipset, the Massive MIMO base station uses a frontal area similar to existing 8-antennas. Integrating antennas, base station units and RFs in one module, ZTE’s Massive MIMO base station uses only one-third of the installation space of traditional systems, lowering operating costs and total cost ownership of operators.
“Being a pre-5G technology, ZTE’s Massive MIMO solution is delivering exponential advances to 4G networks without modifying existing air interfaces, making it possible for carriers to provide a 5G-like user experience on existing 4G handsets in an accelerated timeframe,” said Dr. Xiang Jiying, Chief Scientist of ZTE. “ZTE successfully overcame the challenge of doing multi-user and multi-stream spatial multiplexing in a scattered-signal environment, clearing the main hurdle in the development of Massive MIMO technology.”
