Recently, Hunan Telecom, working hand - in - hand with Huawei, has accomplished a comprehensive network upgrade for the Hunan section of the Beijing - Guangzhou High - Speed Railway. Through the deployment of wide - angle MetaAAU technology, a “2.1G + 3.5G” dual - layer network has been set up. This has led to an increase in 5G coverage, jumping from 95.1% to 97.7%, and has roughly doubled the average download speed.

Previously, the single - layer network along this railway route faced difficulties in keeping up with the ever - growing demands and had issues with coverage. The newly introduced 3.5G wide - angle MetaAAU represents a breakthrough from traditional models. It allows for a cost - efficient two - sector network construction, striking a perfect balance between performance and cost.

This upgrade has substantially enhanced network coverage and greatly improved the user experience, paving the way for the development of 5G - A networks. At present, Hunan Telecom has launched a Phase II optimization plan, with the goal of transforming this railway route into the country's first 5G - A high - speed railway demonstration line.
