Datang Telecom Group sells equipment to Chinese mobile network operators[2] and also provides military communications infrastructure to the People's Liberation Army.

In 1998 a limited company Datang Telecom Technology was also incorporated and floated in the Shanghai Stock Exchange on 21 October 1998.

[citation needed] In April 2007, Datang secured a 36.6% share of China Mobile's first large-scale TD-SCDMA network construction contracts.

[7] Datang's business areas include high-capacity digital switching, optical networking, data communication, and digital microwave communication equipment and software and system integration services.

However, revenue from these sectors is far outweighed by the company's spending on TD-SCDMA research and product development, and in recent years the company has taken out a series of heavy loans from state-owned Chinese banks to fund this development.
