Huawei and Anhui Telecom cooperate for the first time to achieve a new dual-band dual-mode 5G and 4G experience on high-speed rail

On December 25, Anhui Telecom cooperated with Huawei and achieved an important technological breakthrough in the Tongling section of the Hefu-Fuzhou High-speed Railway. They successfully completed the first commercial verification of the 1.8GHz 2.1GHz dual-band 8T8R RRU. This milestone means that 5G and 4G networks can be activated simultaneously on the same device, achieving wide coverage of dual-band dual-mode.

According to my understanding, by opening 4G in the 1.8GHz frequency band and 5G in the 2.1GHz frequency band, This technological breakthrough enables users on high-speed rail to get the best network experience on the same device. This technology uses advanced 8T8R technology, which includes innovative technologies such as high-gain array, precise beam scanning and high-resolution airspace pairing. Compared with traditional 4T4R base stations, through multi-antenna beam shaping and 3D beam technology, wider coverage, better network experience and lower energy consumption are achieved. In addition, this technology also uses the industry's unique true wideband power amplifier to achieve millisecond-level power sharing between the 1.8GHz and 2.1GHz frequency bands, avoiding waste of power allocation

According to the test results, using this technology Afterwards, 5G coverage increased by 5dB, the average downlink rate increased by 18%, and the average uplink rate increased by 43%, compared with traditional 4T. At the same time, 4G coverage has also been significantly improved, increasing by 2.6dB. Within the demonstration line, the total traffic volume increased by 42%. This means that no matter whether high-speed rail users access 5G or 4G, they can enjoy the best network experience

High-speed rail passengers can now easily enjoy smooth live video broadcasts, high-definition videos, new calls, etc. during their journeys Entertainment business, while also conveniently carrying out important work tasks such as remote phone calls and telecommuting. This technological breakthrough will further promote the application of 5G on high-speed railways and provide users with a better communication experience

The above is the detailed content of Huawei and Anhui Telecom cooperate for the first time to achieve a new dual-band dual-mode 5G and 4G experience on high-speed rail. For more information, please follow other related articles on the PHP Chinese website!
