The 80,000-seater venue, nicknamed the "Big Lotus", is set to stage the Opening and Closing Ceremony as well as host the athletics events.

China Mobile, the official partner for communication support at the Hangzhou 2022 Asian Games, selected Huawei's products and solutions and agreed to use 2.6 GHz and 4.9 GHz bands to provide 5G coverage in enclosed ultra-dense areas.

More than 400 5G devices were used during the verification tests at the venue to perform stress tests with multiple networking solutions involving intra-frequency, staggered-frequency, inter-frequency, and distributed massive multiple-input and multiple-output, or MIMO.

Huawei said the cells were "under extreme capacity levels" and 5G user behaviour was also simulated to assess the performance of capacity increase, interference mitigation, and network redundancy.

"The test results showed that the uplink capacity was 50 per cent greater than that obtained with cell splitting and the downlink and uplink interference is efficiently curbed," a statement from Huawei read.

"This level of performance suffices to fulfil the tremendous service requirements for messaging, internet access, video transfer, and broadcasting with good user experience.

"This will be essential for network assurance in the smart stadiums for the 2022 Asian Games."

The 2022 Asian Games are due to run from September 10 to 25, with 40 sports on the programme and more than 10,000 athletes expected to compete.

China Mobile's provincial branch of Zhejiang established a work team with Huawei to explore new bands, products, solutions, features, and approaches to increase capacity and resolve strong interference in ultra-dense indoor areas.

"There will be a large number of 5G users and diverse services occurring during the Games," Huawei said.  

"With this in mind, the work team serves to work out solutions that can increase network capacity while minimising the rate loss arising from interference between cells.

"A balance between 5G capacity and service experience is essential to enable dedicated smart services by improving both user-perceived rate and network capacity.

"It will also prove helpful when building 5G networks in other dense scenarios as an experience in delivering superior user experience."

Huawei said China Mobile Zhejiang was striving to build "high-quality" 5G networks to provide users with premium services and help Hangzhou host the Games while "supercharging it with smart services".

"Indoor distributed Massive MIMO will be the ideal option for large venues with a large number of 5G mobile users who are looking for a smarter spectating experience," Huawei added.

"It will play a crucial role in making the Hangzhou Olympic Sports Center stand out as a benchmark for smart stadiums across China and beyond."
