In June 2019, MIIT issued four licenses for the commercial deployment of 5G in China – a year ahead of the expected timetable. China Radio and Television was granted the “golden” 700 MHz band, and becomes a prospective new tenant on China’s ~2mn telecom towers. With the 5G licenses came a new commitment to China’s “co-build, co-share” philosophy, and a new set of guidelines set out in Document No. 123, which obligates local government in China to build databases of potential 5G sites, and to share their own sites to contribute to the common goal of the swift, efficient deployment of 5G in China.
