Datang Telecom Technology

Datang Telecom Technology Co., Ltd., known as Datang Telecom or DTT, is a Chinese state-owned listed company based in Beijing. Established in 1998 as the listed subsidiary of the China Academy of Telecommunications Technology (CATT, trading as Datang Telecom Group), it was the first Chinese state research institute to be restructured into a publicly listed company. Once a telecommunications equipment maker grouped with Huawei, ZTE and Julong Telecom as one of China's "big four" domestic telecom vendors (the so-called "Ju Da Zhong Hua"), the company suffered prolonged losses following the commercial failure of the TD-SCDMA 3G standard developed by its parent, and repeatedly faced delisting from the Shanghai Stock Exchange. After a series of divestments and restructurings, its business now centres on security chips and special-purpose communications. Since 2018 its ultimate parent has been the China Information and Communication Technologies Group (CICT), a central state-owned enterprise supervised by SASAC.
