Qingdao urban area launches the country's first 100-station three-carrier aggregation contiguous deployment, ushering in the official start of the 5G-A era

Huawei and Shandong Mobile jointly successfully opened 500 three-carrier aggregation sites in Qingdao, making Shandong Mobile the first operator in the country to continuously deploy three-carrier aggregation at 100 sites. This initiative will provide Shandong Mobile users with faster and more stable network connections.

This batch of three-carrier aggregation sites mainly covers multiple hot spots in Qingdao, including May Fourth Square, Badaguan Scenic Area, Qingdao North Railway Station and Ocean University of China. By combining the 2.6G 160M and 4.9G 100M frequency bands, the deployment of three-carrier aggregation in urban hotspots is achieved, providing users with an extremely fast experience of more than 4Gbps in 5G-A premium areas. In addition, Qingdao’s urban area, as the location for 100-station three-carrier aggregation, has further expanded its coverage, including universities, medical institutions, pedestrian streets and important transportation hubs. In this way, the practicality and performance of 5G-A three-carrier aggregation have been fully verified in various scenarios.

According to the editor’s understanding, Shandong has taken the lead in completing the construction of the province’s first batch of 5G-A three-carrier aggregation sites in Qingdao and Weihai at the end of 2023. The successful pilots in these two places not only achieved the milestone of 5G-A downlink peak rate exceeding 4Gbps, but also fully proved Shandong Mobile's deep strength in the field of 5G-A technology. Huawei further revealed that it plans to promote 5G-A three-carrier aggregation terminals for large-scale commercial use this year. This move is expected to provide strong network support for the rapid development of cutting-edge industries such as VR, AI, and naked-eye 3D. 5G-A, full name 5G-Advanced, also known as 5.5G, represents the latest evolution direction of 5G technology. Its most significant features include larger bandwidth, wider connections, and more deterministic latency. As one of the core technologies of 5G-A, three-carrier aggregation (3CC) is the key to building a 5G-A basic experience network. It can provide users with efficient three-carrier networking solutions combined with advanced deterministic experience assurance technology. to achieve unprecedented improvements in network quality and experience.
