High-tech cabins at the Beijing media center also give journalists the chance to catch up on some sleep. The 20 cabins were developed by China's Keeson Technology Corp, and with a simple scan of their phone media representatives can use them for power naps for up to an hour.

The spacious cabins are equipped with the same type of beds provided for the athletes. Users adjust the position of the beds, which have a massage setting, by using a remote control or their phone.

This month, United States luge athlete Summer Britcher said on a social media platform that the beds' "zero gravity" mode can produce the "phenomenal" feeling of being in outer space.

A reliable system for broadcasting Olympic events is also key to ensuring that more people enjoy the top-level competition, given that many spectators, especially foreigners, have been unable to attend the Games due to the COVID-19 pandemic.

Dong Quanwu, director of the research and development department at Beijing International Cloud Broadcasting Technology Co, said traditional broadcasting methods are mostly asset-heavy and require expensive trucks and a large number of production directors.

Many tasks can be accomplished much more easily by using 5G and cloud technologies. A powerful, cloud-based rebroadcasting system means much of the editing work can be done remotely by people in other locations－for example, without the need for a broadcasting vehicle or numerous workers at the scene, Dong said.

On-site reporters now use a small camera or smartphone equipped with a stabilizer to livestream a sports event, thanks to 5G and cloud technologies, Dong added.

Zhang Xiaoyang, a technical manager for the Beijing 2022 organizing committee, said the pandemic has posed many challenges for the Games, but has also produced new opportunities to develop technologies.
