Traffic cameras ‘will need 500Mbps’ per crossroads, says Huawei executive

Smart road-traffic monitoring is going to put a huge burden on carrier networks over the next few years, a senior Huawei executive warned this morning.

Ryan Ding, CEO of the Chinese company’s carrier business group, told a conference in Geneva that smart traffic video cameras in urban transport will need considerably faster uplink bandwidths that used today.

Cameras across three lanes require about 100Mbps upstream, and the full monitoring of a crossroads needs around 500Mbps,” Ding told Huawei’s Ultra Broadband Forum.

Carriers will also need to take account of latency demands from popular video games, Ding told the conference.

“Video games are very hot now. Player Unknown’s Battlegrounds hits 400 million players in June this year,” he said. “Interactive gaming is very sensitive to latency.”

A human in the game moves at about 4 metres a second, “and 90 milliseconds of latency means a 36 centimeters movement escape”, he said. “That decides your survival or death in the game.” Huawei is already working with China Mobile to monetise low latency for gaming, said Ding.

Virtual reality (VR) headsets will put new demands on networks, he said. “VR rendering requires a very high-performance computer, so it is much better to do it in the cloud, which can also reduce the cost of the headset.” He said cloud VR headsets are already available at $300.

“Cloud VR has very high requirement for network. An 8K [picture quality] cloud VR needs 260Mbps bandwidth; 12K cloud VR needs 1Gbps; and latency need be less than 20 milliseconds.”

Huawei has built several video cloud service centres – including the Netherlands, Hong Kong and Latin America – to help telcos aggregate and innovate in video content, and quickly develop new services,” he added.

“Huawei has already worked with more than 50 partners in cloud VR. In the future, we will integrate edge computing capabilities into network, to make VR headset simpler and reduce the cost up to 70%. China Mobile has launched first commercial Cloud VR service in July this year.”
