The Institute of Telecommunications Research reports that the 5G indoor coverage rate is only 60%.

In the third and fourth quarters of 2021, the China Telecom Research Institute selected 9 major scenes in 38 cities to conduct large sample size tests on 5G network coverage, 5G users' use of VoLTE voice and Internet access, and mainstream Internet applications, with a total sample size of over 150 million. The report evaluates the perceived quality of 5G network coverage and the combined network perception of 5G users' VoLTE voice and Internet access services based on the above-mentioned sampling data and weighted by the user shares of the three basic operators. The report said that the current 5G user perception quality composite score is 89.3, of which the 5G network coverage score is 80.4, the basic business (including VoLTE voice and web page opening) score is 97.2, and the online applications (WeChat, Jitterbit video and live streaming, Tencent video, HD video, games, etc.) score is 93.2. From the perspective of 5G network coverage, the main roads, users' high-frequency use scenes outdoor The 5G coverage rate is around 90%, but the indoor coverage rate is only around 60%, and the 5G coverage rate in enclosed areas such as underground parking lots, elevators and staircases is less than 50%; the 5G coverage rate of the ring highway, airport highway and subway lines is around 50%, and the average level of 5G coverage along the high-speed railway is only around 10%. Except for the high-speed railway, the connection rate of voice services in various scenes in each city is greater than 99%, the dropped call rate is less than 0.5%, and the online application experience is excellent; the connection rate of the high-speed railway scenes is about 98.2%, the dropped call rate is about 1.3%, the call quality is less than 80%, and the online experience is yet to be improved, and the web page opening time delay is less than 80%. The average 5G uplink rate is 60.23Mbps and the average downlink rate is 442.84Mbps in all scenarios, both higher than the 4G rate. The report concluded that the current 5G network has met the basic needs of users' network experience, but there is still a gap between the 5G experience and the intergenerational scalability. The report also made several recommendations for 5G network construction and optimization based on the situation reflected in the test: First, in the core urban areas, 5G network construction should be developed in depth, and deeper indoor and outdoor 5G network coverage and room division optimization should be enhanced for high-frequency usage scenarios of users. Secondly, operators can accelerate the scale development of innovative 5G products and applications through both independent research and development and ecological cooperation, so that content operation products and services such as UHD/AR/VR can become the gas pedal of 5G value operation and perception enhancement. Thirdly, users' perception of 5G network usage is directly reflected in the network experience of the head Internet application, and the location of the local downstream server of the Internet application, especially the head application, is also extremely important, so operators can strengthen cooperation and collaboration with Internet application service providers to improve the 5G users' network experience end-to-end.
