China Mobile and Huawei build high/low-band 5G trial field

China Mobile Research Institute, China Mobile Shanghai and Huawei have jointly established a 5G trial field to verify 5G high-band and low-band coordination technology at Huawei’s Shanghai R&D Center.

Huawei said the trial field will be able to verify 5G network performance and key technologies with a high degree of simulation of real networks. The trial field will also serve as a vehicle to showcase the user experience of future 5G services.

The 5G trial field includes seven 5G low-band (sub-6 GHz) sites with continuous coverage. Joint test results between Huawei, CMRI and China Mobile Shanghai already indicate that the average user data rate can reach 1.7 Gbps using 200 MHz of low-band spectrum. By combining low bands with millimeter-wave bands for hot-spot scenarios, a 5G dual connectivity network can provide 18 Gbps of single-user peak throughput, Huawei said.

Vendors targeting the 5G space are starting to emphasize 5G’s ability to work across frequencies as low as 700 MHz up into the millimeter-wave bands of 28 GHz and higher to support everything from dense urban environments and indoor coverage to wide-area rural deployments and IoT connectivity.

Earlier this week at 5G World, Nokia made a point of touting the ability of its AirScale radio portfolio to support both low and high bands for 5G deployments without the need for complicated network reconfigurations or junking legacy network gear.

“Enabling operators to leverage their existing assets allows them to accelerate the rollout of 5G into lower frequency bands as cost effectively as possible,” said Harold Graham, head of Nokia’s 5G business line.

Meanwhile, China Mobile’s Quanzhou branch has announced that they have completed commercial deployment of ZTE’s “pre5G” 3D-MIMO solution.

With 16 commercial massive MIMO terminals connected, China Mobile Quanzhou boosted its single-carrier downlink peak cell rate to 730 Mbps, while the single-carrier 16-stream downlink peak rate of 3D-MIMO reached 700 Mbps for the first time, with the three-carrier rate up to 2.1 Gbps. The three-carrier eight-stream downlink rate with 3D-MIMO reached 1 Gbps.
