1, 4G network downlink peak rate of up to 100Mbps (100 megabits per second), describing the transmission rate, usually also known as the "bandwidth.

2, for example: assuming 100M speed, such as mobile 600M 4G package traffic can be used how long? Some professionals say that 100Mbps in theory can achieve the fastest download speed is 12.5MB per second, in fact, taking into account the process of network transmission also need to pack the information, etc., so you need to discount, that is to say, 600M of data in the high-speed network environment to download, although not up to 6 seconds to use, but the fastest a few minutes will be used up.

4G is short for fourth-generation mobile communications technology. China Mobile's 4G uses TD-LTE, one of the 4GLTE standards. the TD-LTE demo network can reach a theoretical peak transmission rate of 100Mbps downstream and 50Mbps upstream. TD-LTE is a China-led standard for 4G networks, with mature technology and conditions for large-scale rollout, and has been formally commercialized.

By the end of 2014, China Mobile will have completed the construction of 700,000 base stations, the number of which accounts for 40 percent of the global 4G base stations and 80 percent of the TD-LTE base stations. Xi said in 2015 China Mobile's 4G base stations will reach 1 million.

In terms of 4G users, Xi said China Mobile's 4G users are expected to exceed 80 million by the end of the year, and will grow to 250 million in the future in 2015.In May 2018, China Mobile released its April operating data. The data showed that China Mobile had its first negative growth in 4G users, losing as many as 2.427 million users in a single month.
