ZTE says that it has completed pre commercial field testing of the world’s first pre5G 3D Massive MIMO (Multiple Input Multiple Output) base stations in partnership with China Mobile.
Using ZTE’s latest 64-port/128 antenna 3D/Massive MIMO base station, with a much higher PDSCH beam forming gain, the test shows an coverage enhancement for tall building, with improvement for indoor reception. This further demonstrated the superiority of the new technology over existing intelligent antennas in complicated multi-path urban and indoor areas, as well as open rural areas.
The new ZTE solution is enabled by the company’s high-performance vector processor SOC chipset, and brings 3D/Massive MIMO, a key technology for 5G, closer to commercial reality.
The CTO of ZTE’s Wireless Division, Dr. Xiang Jiying, said that, “As the number of antennas is ten times more, 3D/Massive MIMO had appeared to be a distant pipe-dream. However, the test indicates that we are taking a big step forward to realize the new technology using 4G handsets. This is a result of a number of innovations, and is in line with the pre5G concept previously proposed by ZTE. We will continue to deliver Pre5G features to offer 5G-like experience before 5G standardization.”
3D/Massive MIMO, using the multi-antenna technology, improves wireless spectrum efficiency exponentially, increases network coverage and system capacity, and helps telecom operators maximize the use of existing site locations and spectrum resources. According to the simulation, the throughput can be 4-6 times higher. ZTE attaches high importance to the research and development of 5G products, and has achieved breakthrough developments in a series of key technologies.
In particular, ZTE has achieved backward compatibility with 4G, forward service of 5G, product commercial capability, antenna design, engineering convenience, and system performance. 3D/Massive MIMO not only supports China Mobile’s mainstream 4G frequency bands, but is also compatible with existing commercial terminals.
