Nokia and China Mobile trial centralised RAN over 4G inside sports stadium

Trial featuring 6,000 people in Beilun Stadium improved upload speeds by 62% compared with normal 4G and devices were receiving data at speeds of 12Mbps

Nokia and China Mobile trial centralised RAN over 4G inside sports stadium

Nokia and China Mobile have conducted a trial of centralised RAN technology over 4G in a sports stadium to demonstrate how the combination can meet the high-speed, high-bandwidth demands generated by big sporting and entertainment events.

Nokia reported that some 6,000 spectators inside the stadium were provided with ‘an exceptional high-quality, high-speed mobile experience’, with upload speeds improved by 62% when compared with existing TD-LTE networks in high-traffic locations.

The two companies deployed centralised RAN technology in a TD-LTE network running over Nokia Flexi Multiradio 10 base stations at the Beilun Stadium in Ningbo, China. The technology monitored the signals of up to six radio cells, combining those of the best four to communicate with subscribers' devices and turn interference into useful traffic.

During peak usage times, devices were receiving data at speeds of 12 megabits per second (Mbps) or more, allowing users to use webchat applications and upload pictures without service degradation. The power efficiency of their devices was also improved by up to 33%.

Nokia's centralised RAN technology can be deployed via software upgrade to an existing Flexi Multiradio 10 Base station network. For mobile operators, centralised RAN is a key step in their Cloud RAN network evolution.

Wang Yong, assistant to the general manager at Ningbo Mobile said: "Nokia is China Mobile's important strategic partner in TD-LTE. Technology innovation and improvement has always been Ningbo Mobile's focus.

“With this successful trial, we have shown that centralised RAN technology can eliminate the 4G network strain typically caused at large events. As mobile data use continues to rise, innovations like this from Nokia will help us meet the demands for high-quality service from our subscribers in densely populated stadiums and other areas.

Yu Xiaohan, head of CBT CMCC at Nokia Great China, said: "Our innovative technology offers a compact, high performance and cost-optimised solution to meet operators' high traffic needs. We are the first to demonstrate this technology on TD-LTE at an event attended by the customers of an operator in China, demonstrating how we can offer mobile operators new efficiencies as their networks continue to evolve to satisfy ever-growing data and quality demands.

“As a new technology incubator, Ningbo Mobile has helped with the trialling and go-to-market of Nokia's TD-LTE new technologies and new versions, and this time we successfully demonstrated together how to solve consumers' problem of a bad surfing experience in densely populated area."
