The most crucial aspect in the wireless industry is the frequency band resources of wireless technology. To help us have a clearer understanding of wireless frequency bands, we have compiled the wireless frequency allocation table from the internet as follows: (Please consider saving it)

1. 5G frequency band allocation

2. LTE/LTE-Advanced/LTE-Advanced Pro

3. WCDMA/HSPA/HSPA

4. TD-SCDMA

5. GSM/GPRS/EDGE/ EDGE Evolution/VAMOS

Remark:

• P-GSM，Reference GSM-900 frequency band

• E-GSM，Expand the GSM-900 frequency band (including the base GSM-900 frequency band)

• R-GSM，The railway GSM-900 frequency band (including the base and extended GSM-900 frequency bands)

• T-GSM，Cluster wireless system - GSM

• ER-GSM900，It is called Extended Railway GSM 900. It expands the frequency range of the original railway communication system (TX: 873-915, RX: 918-960).

8. The field of public safety

9. Low-power Wide Area Network (LPWAN)

10. Other wireless connections

Frequency allocation of the three major telecommunications operators

Annotation: 

• Yellow protection band: The original mobile used 1880-1900 (20M), and the electrician used 1860-1875 (15M). Due to interference between TD and FDD, 5M from 1875-1880 needs to be reserved as an isolation band. After the telecommunications cleared the small cellular frequency band (1900-1920) and returned it to the mobile, the mobile then had a complete 40M frequency band from 1880-1920. However, the isolation band was provided by the mobile side from 1880-1885. Thus, the telecommunications could use 1860-1880 for a complete 20M carrier. The mobile used 1885-1920 for 35M.

• According to the "Relevant Approval from the Ministry of Industry and Information Technology on China Telecom's Use of 800M and 2100M Frequency Bands for LTE Networking" issued in June this year, China Telecom can re-allocate LTE FDD on the CDMA 1X/DO frequency bands at 825-835/870-880, 1920-1940/2110-2130.

• According to the recent "Relevant Approval from the Ministry of Industry and Information Technology on the Adjustment of Some Frequencies by China Unicom for LTE Networking", China Unicom can reassign the frequencies originally used for 2G and WCDMA (909-915/954-960, 1735-1750/1830-1845, 1940-1965/2130-2155) for LTE FDD use.
