With the in-depth construction of 5G, high-capacity scenarios such as large stadiums and concerts face challenges in coverage and uplink and downlink capacity. recently,Zhejiang Telecom and Huawei completed innovative commercial testing of FDD Massive MIMO in Ningbo, demonstrating its powerful network capabilities.
The test results show thatCompared with traditional 4T4R technology, the coverage capability is enhanced by 8dB, the downlink capacity is increased to 4.7 times, and the uplink capacity is increased to 4.3 times.
This achievement means that the current problems of deep coverage in dense urban residential areas, ultra-long-distance coverage at sea, and limited uplink and downlink capacity in large stadiums and concerts can be effectively solved.
In addition, major upward demands such as Internet celebrity live broadcasts, RedCap video networking and car networking will also receive strong support.
Huawei said that FDMassiveMIMO strengthens multi-antenna technology, which is not only simpler and greener, but also significantly improves system capacity.
Especially in the uplink, large-scale intelligent receiver technology has effectively enhanced uplink coverage and improved uplink MU-MIMO pairing efficiency, fully meeting the demand for large uplink capacity in the mobile AI era.
