China Telecommunications Technology Labs selects Spirent for TD-LTE testing

Spirent Communications has announced that China Telecommunications Technology Labs (CTTL), a leading wireless test and certification organisation under China Academy of Telecommunications Research (CATR), has selected the Spirent VR5 HD Spatial Channel Emulator to advance their TD-LTE device test environment.

TD-LTE is the time division duplex (TDD) flavour of LTE, which operates in a single frequency band as opposed to the paired bands required by the frequency division duplex (FDD) flavour of LTE, which has already seen wide commercial deployment. At a time of global pressure on spectrum, single-band operation makes TD-LTE an attractive option to many network operators, with much of the initial focus in Asia.

With TD-LTE trial deployments ongoing in cities across China, there is a strong push towards commercial TD-LTE readiness. CTTL is a national-level telecom research institution of the Ministry of Industry and Information Technology (MIIT). Since one of its core functions is testing and certification of telecom products, CTTL is a key player in the drive towards the commercial readiness of TD-LTE. Spirent’s VR5 will play a critical role in helping CTTL to ensure the targeted levels of TD-LTE performance will be achieved in a timely manner.

“We sincerely appreciate the recognition from such an influential organisation as CTTL,” said Spirent Vice President Rob VanBrunt. “Spirent is excited to be a part of the push towards commercial TD-LTE and is continually evolving our test solutions to advance wireless technologies on a global scale.”

The Spirent VR5 Channel Emulator is claimed to be the industry’s most advanced solution for emulating the complex RF channels needed in testing advanced wireless technologies such as TD-LTE. Its unique phase calibration capability is said to dramatically simplify MIMO/beamforming testing for TD-LTE and allows more test campaigns to be run in less time.
