Chunghwa Telecom Co. Ltd. is Taiwan's largest integrated telecom service provider. It was established on June 15, 1996, following the Taiwanese government's push for privatisation. Before its establishment as a company, Chunghwa Telecom was a business unit of the Directorate General of Telecommunications for over a century. The company offers a broad spectrum of services including PSTN, mobile, and broadband services. The company's shares have been publicly traded on the Taiwan Stock Exchange under the ticker "2412" since October 2000, and on the New York Stock Exchange under the symbol "CHT" since July 2003. In August 2005, the company underwent privatisation as the Taiwan government's ownership was reduced to less than 50%. Chunghwa Telecom's corporate history is marked by its transition from a government monopoly to a privatised entity, reflecting the wider liberalisation of Taiwan's telecommunications industry from the late 1980s.

Chunghwa 4G Network

Chunghwa launched 4G LTE in May 2014, becoming the first operator in Taiwan to do so. The network implemented B3 (1800 MHz) and B8 (900 MHz). LTE-Advanced was activated in December 2014, using 2C carrier aggregation of B3+B8 with 15 MHz and 10 MHz channels respectively. Following the acquisition of 2600 MHz spectrum, Chunghwa Telecom expanded its LTE-A network in March 2016 to include a B7 (2600 MHz) carrier, with 3CC CA, achieving peak data rates of 340 Mbps.

In July 2017 following the switch-off of legacy GSM services, the company implemented 4CC CA, refarming and using a second B3 (1800 MHz) carrier, taking peak data rates to 500 Mbps.

By Mid 2018 the company had implemented a raft of LTE-A Pro features, including 5CC CA, 4X4 MIMO, 256QAM, and LTE-U LAA, taking peak data rates to nearly 1 Gbps.

The company contracted Ericsson to construct an end-to-end NB-IoT system in mid 2017. After almost a year, Chunghwa had completed a number of soft launches of its NB-IoT network which is understood to be using the company's existing B3 and B8 carriers.
