ZTE and China Telecom launch the world’s first commercial 5G magnetic levitation

ZTE and China Telecom launch the world’s first commercial 5G magnetic levitation high-speed network test

The test achieved extremely high data rates in ultra-high mobility

29 November 2019, Shenzhen, China: ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, today announced that ZTE and China Telecom have jointly launched the world's first commercial 5G maglev (magnetic levitation) high-speed network test in Shanghai, China. The test measured communications within a train travelling at a maximum speed of 500KM/h. During the test, the 5G commercial terminal was stable and easy to support various high performance mobile broadband services, demonstrating that the 5G network can provide high-speed maglev trains with ideal broadband communications.

Shanghai Maglev is the world's first maglev line for commercial operation and at present it is also the fastest commercial high-speed train. It has been a business card for Shanghai and even for China since its operation. Built by China Telecom and ZTE together, the 5G network uses a full set of ZTE 5G system equipment, perfectly enabling passengers to get high-speed data access on a quick journey and enjoy services like mobile working, video conferencing, HD/UHD video or interactive games, ensuring a brand-new communication experience.

Due to special scenario restrictions, providing high-quality network coverage for high-speed trains has always been a challenge for both operators and equipment vendors. When a 5G network is deployed in a higher frequency than 2G, 3G and 4G networks, the situation will be even less ideal. To solve these problems, ZTE and China Telecom have made breakthroughs in multiple aspects by constantly challenging the technical limits through technological discussions and tests. With proprietary doppler frequency shift channel compensation technology, wireless channel deterioration caused by high-speed movement is eliminated. The solution can support a moving speed of over 500 KM/h, meeting the speed requirements of various high-speed trains. Besides, Multi-RRU (Remote Radio Unit) combination can realize single cell 6-12km belt shape coverage, reduce 90 percent of inter-cell handover and ensure continuous and stable access. Compared with the traditional 2T2R solution, ZTE is the first to introduce 8T8R RRU for high-speed railway coverage in the 5G industry. Multi-channel equipment, combined with 5G featured channels and beam scanning technology, can enhance the coverage significantly. It is also worth mentioning that the solution is implemented through technical innovation at the base station network side and has no special requirements for terminals.

The 5G network solution used for the Shanghai Maglev line can provide a complete set of network equipment for HSR (High Speed Rail) broadband communication. The radio units can support global mainstream 5G bands like N41 and N78. The top speed of Shanghai Maglev train is the highest among commercial trains in the world, which implies that this 5G network solution can be applied to various high-speed railways and maglev lines worldwide and has great market potential.

Over the years, ZTE and China Telecom have jointly provided broadband information channels for high-speed rail transit. LTE coverage has been deployed for multiple high-speed railway lines, which was highly appraised by users. Going forward, the two parties will continue to optimize the commercial performance of the 5G networks and steadily promote tests and verification according to specific service characteristics to facilitate ubiquitous high-speed broadband access.
