It is a social organization formed voluntarily by enterprises who actively commit themselves to the development of TDD mobile communication technology and engage in the R&D, production and service of TDD standard and products. The primary objective of TDIA is to develop and promote the TDD technology. By integrating and coordinating industry resource, TDIA hope to stimulate the development progress of TD-SCDMA ，TD-LTE and its evolution technology to enable its global deployment and operation.
By Nov 2011, TDIA has 90 members, including mobile operators, equipment manufactures, software vendors and distributors. The research fields of TDIA members cover end to end industrial chain, including RAN,CN,RF devices, antenna, UEs, chipsets, testing instruments, software, service and applications.

Secretariat conducts routine operation. Secretariat has five management sections: Industry Department, Marketing Department, Business Development Department, IPR Department and Market Research Department.
To stimulate the development of TD-SCDMA and TD-LTE，TDIA setups specialist working group to address emerging and vital technical aspects in the course of TDD industrialization development. Presently, TDIA Technical Working Groups include LTE WG，network optimization WG, standardization WG, mobile system WG ( radio resources management team and frequency resource management team), chipset and end-user device WG, UE COT WG, service and applications promotion WG， testing instrument WG. |
