Anritsu Introduces Machine Learning Software To Optimize 5G UE mmWave 3D EIS Scan Test Times

New Option for Radio Communication Test Station MT8000A Improves Test Efficiency and Helps Speed UE Time-To-Market

Anritsu Company introduces the Equivalent Isotropic Sensitivity – Cumulative Distribution Function (EIS-CDF) Optimization Using Machine Learning MX800010A-026 software option for its Radio Communication Test Station MT8000A. This uses machine learning to optimize 5G millimeter wave (mmWave) 3D EIS Scan (EIS-CDF) test times. With the machine learning software installed, the MT8000A reduces tests times of two mmWave UE models by 35% to 60% compared to alternative methods to help speed time-to-market.

The MX800010A-026 software option supports 3D EIS Scan tests using Anritsu’s CATR Anechoic Chamber MA8172A by automatically learning the UE antenna properties to facilitate test efficiency. Multiple repetitions of the 3D EIS Scan with the same UE optimizes the test efficiency.

Development Background
Anritsu developed the MX800010A-026 software to address the rollout of ultrawideband 5G Frequency Range 2 (FR2) mmWave services that is gaining momentum in certain regions, including North America and Japan. As a result, R&D and conformance tests of mmWave UE are expected to become active markets in future.

The 3GPP standard specifies tests of mmWave UE antenna properties in 3D in an Over-the-Air (OTA) test environment. 3D testing inherently requires extended test times due to it requiring a large number of measurement points. Test time can be greatly shortened using machine learning. For this reason, it is expected to become the preferred method to optimize test efficiency for mmWave UE.

Product Outline
The all-in-one MT8000A platform supports RF, protocol, and application operation tests, as well as beam verification and evaluation of beam characteristics. In addition to having a function for simulating Non-Standalone (NSA) and Standalone (SA) base station operation required for developing 5G chipsets and UE, the MT8000A supports all 5G Frequency Range 1 (FR1) (600 MHz, 2.5 GHz, 3.5 GHz, 4.5 GHz, and 6 GHz unlicensed) and FR2 (24 GHz, 28 GHz, 39 GHz, and 43 GHz) frequency bands. The CATR Anechoic Chamber MA8172A uses the 3GPP-compliant Compact Antenna Test Range (CATR) method to implement 5G NR OTA tests in a small space. It can be used for mmWave development and conformance tests of 5G NR chipsets and UE.
