NEC and Japanese telecoms NTT Docomo and Nippon Telegraph and Telephone Corporation have successfully transmitted 5G data to a car travelling faster than 300 kilometers per hour.
The aim isn’t to help improve download speeds for people who are driving like maniacs, but rather to simulate 5G data transmission for a high-speed train. After all, much of the promise of 5G connectivity is that it will allow downloads and uploads for consumers in all kinds of environments, including trips on high-speed railways.
Delving into the details, Docomo, NEC, and NTT say the trial saw the wireless transmission of 28 GHz data between a 5G base station and a 5G mobile station using a car travelling at 305 km/h, and that it also entailed “1.1 Gbps ultra-high-speed data transmission via downlink to a 5G mobile station moving at 293 km/h and a fast handover during communication between 5G base stations and a 5G mobile station moving at 290 km/h,” according to a statement from the firms. Additionally, they say it featured a live relay of 4K video from a 5G mobile station moving at a speed of 200 km/h.
The field trial represents only the latest example of the telecoms’ interest in 5G technology, with Docomo having previously worked with Ericsson, Toyota, and Intel on a 5G trial involving data transmissions to a much slower-moving vehicle last autumn. Clearly, the pace of 5G development has shifted gears in recent months, and Docomo, NTT, and NEC are far from the only ones in the race.
