Chamber for 5G Antenna Testing

Anechoic chamber facilitates conformance testing for 5G mmWave products

Anritsu is supplying a compact Antenna Test Range (CATR) Anechoic Chamber in MA8172B configuration for its New Radio RF Conformance Test System

Evaluating UE communications quality and connection stability at handover between base stations is a difficult technical challenge for mmWave mobile communications.

As a result, Anritsu has developed its MA8172B upgrade model for the OTA CATR based on its earlier CATR Anechoic Chamber, the MA8172A. The MA8172B reproduces the radio-wave propagation characteristics of communication between the UE and two base stations compliant with 3GPP.

Additionally, any angle can be set between two base stations in the MA8172B, facilitating a wide range of applications, including both conformance tests and R&D. Moreover, the cost-effective upgrade path from the previous MA8172A helps optimise capital spending.

Rollout of 5G mmWave Frequency Range 2 (FR2) services is going to increase, centred especially on advanced economies, such as North America, Japan, etc., which are expected to promote future mmWave UE R&D and conformance testing. In particular, expanding service areas in the north American market will drive demand for performance tests of mmWave UE using FR2 RRM conformance tests including 2 AoA. Currently, mmWave UE must obtain FR2 RRM conformance test certification, and the ME7873NR acquired Global Certification Forum (GCF) FR2 RRM certification.

The ME7873NR is an automated system for 3GPP TS 38.521/TS 38.533 5G NR RF and RRM tests.

In addition to 3GPP FR1 (Sub-6 GHz band), combination with either the CATR Anechoic Chambers (MA8172A or MA8172B) covers tests for all 5G frequency bands, including mmWave Frequency Range 2 (FR2).
