China Mobile and Huawei Achieve 3 Gbps Peak Data Rate on a 4.9 GHz 5G Indoor Network


China Mobile Shanghai and Huawei collaborated to deploy the world’s first 4.9 GHz commercial LampSite network in Shanghai, China. This is the first time that an aggregate bandwidth of 200 MHz on the 2.6 and 4.9 GHz bands and distributed Massive MIMO have been simultaneously implemented in digital indoor networks. With the peak rate exceeding 3 Gbps, the performance is comparable to that of an active antenna unit (AAU), satisfying the network requirements to provide premium service experience at large stadiums where the traffic demand and user density are high.

This deployment was completed at the Shanghai New International Expo Center (SNIEC) where Mobile World Congress (MWC) Shanghai, an annual telecom industry event, is hosted. In 2019, nearly 60,000 people attended this event. The latest 4.9 GHz LampSite units supporting a bandwidth of 100 MHz were adopted to work together with the incumbent 2.6 GHz band to ensure a bandwidth of 200 MHz through carrier aggregation. This enhances the coverage of indoor networks at capacity-demanding indoor hotspots, including stadiums, airports, and railway stations, to deliver premium experience to mobile users.

China Mobile Shanghai has been a leading telecom carrier in developing 5G networks. To date, it has constructed more than 13,000 5G sites, basically achieving continuous coverage in the city. This telecom carrier boasts leading networks and evident technological advantages. It has been working with Huawei to explore innovative solutions to guarantee mobile excellent user experience in various scenarios. 4.9 GHz is an ideal option for telecom carriers to enhance coverage in indoor hotspots, ensuring premium indoor experience for toC services. This band is also important to ensure 5G coverage in high-quality toB applications.

China Mobile Shanghai will continue to work with Huawei to accelerate the deployment of 5G sites to deliver the continuous coverage required to ensure premium service experience across the city. It will also continue to promote the collaboration of the telecom industry with other industries, such as finance, shipping, and trade to cement Shanghai’s leadership in applying 5G to vertical industries by leveraging their respective leading advantages.
