ZTE takes Pre5G 3D-MIMO technology closer to commercial deployment

ZTE has moved its proprietary Pre5G three dimensional multiple input multiple output (3D-MIMO) solution a step closer to commercial deployment after a successful test on China Mobile’s commercial network.

The 3D-MIMO technology helped increase average data throughput by two to four times, with data rates at the cell edge going up as much as five to seven times, according to results from a test in a metropolitan area of Guangzhou.

The pre-commercial test, conducted jointly with China Mobile’s Guangdong provincial subsidiary, and the China Mobile Research Institute, showed the ability of the 3D-MIMO solution to improve network throughput and coverage even in an area with a high concentration of tall buildings.

3D-MIMO technology achieves this by providing more precise beamforming and more effective spatial multiplexing to strengthen a network's resistance to interference, therby improving the performance of cells and the overall network.

The 3D-MIMO base stations feature 128 built-in antenna elements and advanced baseband vector processing chipsets and are fully compatible with existing 4G long term evolution (LTE) infrastructure and user terminals, making them easy for operators to deploy, ZTE said.

In June 2014, ZTE was the first vendor to propose the concept of Pre5G, and the company launched its Pre5G base station integrating base band unit (BBU) and remote radio unit (RRU) technology at Mobile World Congress in Barcelona in March 2015, enabling carriers to emulate the behaviour of future 5G networks on existing 4G LTE network infrastructure.
