Over-The-Air (OTA) measurement.

An enhanced partnership with Bluetest AB of Sweden has been announced by Anritsu Corporation. This offers a new unified test solution for Over-The-Air (OTA) measurement of 5G mobile terminals.

Anritsu and Bluetest have long been working closely for LTE/5G FR1 (Sub-6 GHz band) and FR2 (mmWave) CATR OTA measurements with Bluetest's RTS65 OTA Reverberation Test System, but this enhanced partnership provides further advantages by supporting the new MT8000A Single Instrument NSA solution with Anritsu's MT8000A RF measurement test platform for 5G mobile terminals to implement new LTE & 5G (FR1, FR2) OTA measurements. Generally, a separate call box MT8821C was required for LTE OTA measurements, but this unified solution facilitates LTE, 5G FR1 and 5G FR2 measurements using just one OTA chamber and one single instrument, Anritsu MT8000A, resulting in lower costs for LTE/5G terminal developers as well as for operator specific Carrier Acceptance Tests (CAT) in an LTE/5G OTA test environment. In addition, the unified smaller system also saves valuable laboratory space.

Outline of Unified Test Solution
This solution is composed of the Anritsu MT8000A and MT8821C (now optional), as well as the Bluetest RTS65.

The Radio Communication Test Station MT8000A is an all-in-one 5G test platform supporting RF parametric and protocol tests, functional, and application tests, validation of beam characteristics, and more. It supports Non-Standalone (NSA) and Standalone (SA) mode base-station emulation functions for the development of LTE/5G chipsets and devices supporting both FR1 and FR2. The MT8000A is widely used for conducted and OTA tests to evaluate the performance of LTE/5G devices.

Bluetest's RTS65 OTA Reverberation Test System optimizes the time required for OTA measurements to improve R&D productivity. It supports 5G MIMO measurements on FR1 and FR2, including the 28 and 39-GHz mmWave bands. Its unique design, with both RIMP (Rich Isotropic MultiPath) and CATR (Compact Antenna Test Range) environments, allows for multicarrier MIMO measurements as well as directional measurements on FR2. Additionally, the built-in measurement computer with easy-to-use touch-screen interface helps simplify measurement-results control and monitoring. Using the MT8000A and RTS65 to configure an efficient development environment with RF TRx tests, simulated base-station, and measurement-result monitoring functions, facilitates cost-effective OTA measurements of LTE and 5G FR1/FR2 mobiles.
