China Unicom ensures high-speed connections at World Humanoid Robot Games

At the 2025 World Humanoid Robot Games, connectivity is paramount. Beyond the typical communications required at a large-scale sports event, high-speed connections are a must if the robots are to compete effectively.

The provision of those connections fell to China Unicom Beijing, the event's exclusive global communications partner. China Unicom committed to ensuring millisecond-level network response and zero downtime with its  5G-Advanced (5G-A), AI, and all-optical network expertise through collaboration with partners. 

The company set up full 5G-A network coverage both inside and outside the event venue - the Beijing National Speed Skating Oval. The network, characterised by a high uplink capacity, reliability, and security, enhanced the spectator experience and enabled over 500 robots from nearly 280 teams worldwide to do their best across athletic, performance, industrial, and healthcare contests. 

According to China Unicom Beijing, robots need a specialised network that allows them to perceive their surroundings, make instant decisions, pinpoint their location precisely, and coordinate with other robots.

Inside the Oval, Huawei's LampSite indoor mobile broadband solution delivered 300 MHz bandwidth, achieving a peak network speed of 2.4 Gbps.

A 5G-A digital indoor system leveraged the 300 MHz ultra-high-bandwidth spectrum to support uplink speeds of above 100 Mbps, allowing multiple 4K machine vision streams to be uploaded without frame loss. It also ensured air interface latency speeds of below 20 ms, so robots could respond to commands instantly. 

Outside the Oval, a 5G-A 3D network boosted peak uplink and downlink user-perceived rates to 4 Gbps and 11.2 Gbps, respectively. The connectivity enabled 8K panoramic cameras to merge footage live, and media like CCTV to upload ultra-high definition (UHD) shallow-compressed signals in seconds. The people on-site could also livestream and share videos without lag. 

"Our 5G-A networks currently serve users, and we're upgrading them to support embodied AI as well," said Qin Yang, Deputy GM of China Unicom Beijing, during the event. 

"Our 5G-A network for this event reflects this progress. It dedicates a channel for spectators and a dynamically scalable one for robots, realising seamless connectivity for both spectators and robots even during peak usage. In the robot sector, 5G-A will also be key to enabling low-latency remote control."

Samuel Chen, VP of Marketing for Huawei's Wireless Network Product Line said: “At the Humanoid Robot Games, the network must support many robots, spectators, and live media streams. It needs to provide high uplink capacity, low latency, high reliability, and wide coverage.”
