China Telecom 4G Network
To provide high speed data services 4G LTE TDD was launched over B40 (2300 MHz) and B41 (2500 MHz) in February 2014. In February 2015 China Telecom received additional 1800 MHz licences and permission to refarm existing 2100 MHz spectrum, subsequently launching B1 (2100 MHz) and B3 (1800 MHz) FDD LTE services.
In August 2015 the company launched its LTE-A "Tianyi 4G+" service providing up to 300 Mbps by 2C aggregating B1 with B3.
June 2016 saw China Telecom approved to deploy a B5 (850 MHz) FDD LTE network, and has subsequently enabled 3C aggregation allowing B5 to be attached to both B1 and B3 carriers. VoLTE was also enabled on the service, with a national deployment completed early 2017.
China Telecom claimed the world’s first FDD-TDD carrier aggregation demonstration with peak download speed of 260 Mbps achieved using 20 MHz of B3 (1800 MHz) and 20 MHz of B41 (2500 MHz). The company's B41 service was deactivated as part of China's 5G planning.
While the company began testing back in 2016, March 2017 saw the first commercial use of NB-IoT (LTE Cat-NB1), which China Telecom provides within its B5 (850 MHz) carrier. A full commercial launch and nationwide coverage was achieved mid 2018.

China Telecom 5G Network
Throughout late 2017 China Telecom conducted 5G pilot programs in six cities, including Shenzhen, Shanghai, Suzhou, Chengdu and Lanzhou, with six to eight stations in each city primarily operating over the 3.5 GHz band. In December 2018 China Telecom received 5G test frequencies totalling 100 MHz bandwidth from 3400 MHz to 3500 MHz.
China Unicom and China Telecom agreed to share the construction of base stations in 24 cities, as per an agreement signed on 9 September. China Telecom announced plans to build 40,000 5G base stations by the end of the year. China Telecom launched 5G services on the 1st November 2019 over the n78 (3500 MHz) band.
In August 2023 the company refarmed its legacy CDMA2000 spectrum to launch 800 MHz low band 5G.
