Anhui Telecom, in collaboration with Huawei, has achieved a groundbreaking milestone by optimizing and launching the nation's first 2.1GHz + 3.5GHz 3CC 5G-Advanced network along the Beijing-Shanghai High-Speed Rail. This initiative significantly expands 5G coverage to 98% of the route and propels downstream peak speeds beyond 700Mbps. The Anhui segment of the Beijing-Shanghai High-Speed Rail, stretching approximately 270 kilometers through diverse and challenging terrains, presented numerous obstacles due to the wide spacing between existing wireless stations.

Building upon the existing 3.5GHz 2CC network, Anhui Telecom introduced an innovative dual-band 8T8R solution at 1.8GHz + 2.1GHz, fortifying both 5G and 4G network infrastructures. Through proactive network optimization, precise planning, collaborative problem-solving, fine-tuning, and the deployment of 3CC technology, the 5G network experience for passengers on high-speed trains has been dramatically enhanced.

Looking ahead, Anhui Telecom remains committed to pioneering the advancement of 5G networks, laying a robust foundation to support the thriving digital economy of Anhui province.
