At the same time, the speed-up of home broadband users above 4M will also be launched in the near future, and the overall rate will be gradually increased to 4M and above.

In the second phase, users with a speed of 4M or higher will soon speed up.

Since the second half of last year, China s broadband is considered to have widened the gap with European and American levels, and broadband has become the focus of attention of users and the industry. To this end, the Ministry of Industry and Information Technology also proposed to promote the implementation of the "Broadband China" strategy, and strive to reach the end of the "Twelfth Five-Year Plan" period, with urban households reaching more than 20 Mbps, rural households reaching more than 4 Mbps, and capital cities in the eastern developed regions reaching 100 Mbps.
