Shenzhen leads the country: Guangdong Telecom and Huawei completed the first 3.5GHz+2.1GHz 3CC thousand-cell contiguous deployment, opening a new chapter in 5G-A

Recently, Guangdong Telecom has worked closely with Huawei to successfully complete China’s first 3CC thousand-cell contiguous deployment in Shenzhen in the 3.5GHz and 2.1GHz frequency bands. This cooperation marks important progress in the large-scale application of 5G-A technology. This achievement laid a solid foundation for Guangdong Telecom’s 5G network construction and also provided useful experience for 5G development in other regions across the country.

The deployment adopted innovative FT three-carrier aggregation technology, which enabled the downlink rate to exceed 4Gbps in the test, bringing users an unprecedented network experience. As my country's technological pioneer city, Shenzhen has always been in a leading position in the development and application of network technology. As early as May 2023, Shenzhen announced the 5G-A Pioneer City Plan, committed to building Shenzhen into a leading city in 5G-A technology in the country and even the world.
