Low frequency bands are used for 4G, but China Telecom and China Unicom still have a disadvantage

On December 15, the Ministry of Industry and Information Technology pointed out in its reply that in the spirit of improving the efficiency of spectrum resource utilization, in order to improve the efficiency of frequency resource utilization, in accordance with the "Notice of the Ministry of Industry and Information Technology on Frequency Planning of International Mobile Communications Systems (IMT)", after research and approval, China Unicom agreed to adjust the 900MHz, 1800MHz and 2100MHz frequency bands for LTE networking.

This adjustment includes all of China Unicom's frequency resources, specifically:

• 909-915MHz (sent by terminal)/954-960MHz (sent by base station);
• 1735-1750MHz (sent by terminal)/1830-1845MHz (sent by base station);
• 1940-1965MHz (sent by terminal)/2130-2155MHz (sent by base station).

Specifically, all the 2G/3G frequency bands currently owned by China Unicom can be used for 4G.

Micro review:

1. I believe China Telecom and China Mobile also have similar policies. The mobile communication frequency bands of the three major operators can be adjusted freely.
2. In fact, with the decrease in 2G and 3G users and the lower utilization rate of 2G and 3G networks, the three major operators are actively using their frequency bands for 4G. For example, China Telecom has repeatedly made it clear that it will "recultivate 800M."
3. The use of low-frequency bands for 4G will help China Unicom and China Telecom, operators whose 4G network construction is lagging behind, to quickly improve the quality of network coverage at low cost.
4. Since there are still users using 2G\3G terminals, it is not yet mature to dedicate all 2G\3G networks to 4G.
5. Since China Mobile still has a clear advantage in user base and 4G network coverage, this adjustment is still not enough to narrow the gap between China Telecom, China Unicom and China Mobile in 4G users and revenue.
6. The terminals may become an obstacle to the use of low-frequency bands for 4G.
