New system facilitates 5G mmWave UE rollout

Anritsu Company has created the new CATR Anechoic Chamber 2 MA8172B configuration for its New Radio RF Conformance Test System ME7873NR to support 5G mmWave 2 AoA RRM tests.

Evaluating UE communications quality and connection stability at handover between base stations is a tough technical challenge for mmWave mobile communications. Consequently, the company has created its upgrade model for the OTA CATR based on its earlier CATR Anechoic Chamber MA8172A. The new model replicates the radio-wave propagation characteristics at communications between the UE, and two base stations complied 3GPP.

Also, any angle can be set between two base stations in the MA8172B, enabling various applications comprising conformance tests and R&D. Furthermore, the cost-effective upgrade path from the previous device helps optimise customers’ capital spending.

The rollout of 5G mmWave FR2 services is increasing, particularly in advanced economies, such as North America, Japan, etc., which are expected to facilitate future mmWave UE R&D and conformance testing. In particular, extending service areas in the North American market will push demand for performance tests of mmWave UE utilising FR2 RRM conformance tests, including 2 AoA. Currently, mmWave UE must receive FR2 RRM conformance test certification, and the ME7873NR acquired GCF FR2 RRM certification.

The company is playing a pivotal role in the future commercial rollout of 5G services for a world enjoying the benefits of 5G. The device is an automated system for 3GPP TS 38.521/TS 38.533 5G NR RF and RRM tests.

As well as 3GPP FR1 (sub-6GHz band), combined with either the CATR Anechoic Chamber MA8172A or MA8172B, covers tests for all 5G frequency bands, including mmWave FR2.
