RF Laboratory

 1.  Brief Introduction
As one of the key projects of TA Beijing, RF laboratory was established in 2012. Currently we have five shielding rooms providing testing and debug services for our customers, and we also reserve enough space for further extension, to meet the fast increasing requirement on testing capability and capacity. Instruments are equipped from the worldwide famous equipment and solution providers, providing accurate and reliable test results to the customers.

TA Beijing RF lab has the testing capability of conducted and radiated RF performance for wireless mobile terminal devices. The mainly supported protocol includes: GSM, GPRS, EDGE, W-CDMA, CDMA2000, TD-SCDMA, Bluetooth, Wireless LAN, LTE-FDD, TD-LTE, etc.

Beside basic RF performance, we can also provide testing service on wireless mobile terminal devices mutual interference performance. This testing plays very key role during multi-function or multi-mode terminal devices’ R&D stage. It supports the manufacture to do better designation on the product interoperability performance
