Anritsu and Bluetest partner on 5G FR1/FR2 OTA measurements
Anritsu Corporation and Bluetest AB of Sweden are offering a new unified test system for Over The Air (OTA) measurement of 5G mobile terminals.

Anritsu and Bluetest have cooperated previously on LTE/5G FR1 (sub-6 GHz band) OTA measurements, but this enhanced partnership combines the RTS65 OTA Reverberation Test System from Bluetest equipped with the new Compact Antenna Test Range (CATR) option and the MT8000A RF measurement test platform from Anritsu for 5G mobile terminals to implement new 5G FR2 (mmWave) OTA measurements.

Generally, a separate OTA chamber was required for each LTE/5G FR1 and 5G FR2 OTA measurement, but this unified system facilitates both measurements using just one chamber, resulting in lower costs for LTE/5G terminal developers as well as for operator Communication Acceptance Tests (CAT) in a LTE/5G OTA test environment; the unified smaller system also saves valuable laboratory space.

This system comprises the Anritsu MT8000A and MT8821C as well as the Bluetest RTS65. The MT8000A is a new test platform supporting 5G technologies including wideband signal processing and beamforming required by the enhanced Mobile Broad Band (eMBB) feature of 5G NR. In addition to protocol tests, it supports signalling RF measurements for each 5G NR band, covering the sub-6 GHz bands, such as the 2.5, 3.5, and 4.5-GHz bands, as well as the 28 and 39-GHz mmWave bands.

The MT8821C facilitates RF TRx and maximum throughput measurements of 2G, 3G, and LTE mobile terminals using one instrument.

Bluetest has created a unique OTA Reverberation Test System in the RTS65 by combining the reverberation chamber and a CATR into the same chamber. The CATR system is enabled by a carefully designed dual-reflector system combined with a patented frequency selective absorber system.
