Anritsu and Bluetest partner on 5G FR1/FR2 OTA measurements
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.
The wide range of measurement antennas support 5G measurements, including the 28 and 39-GHz mmWave bands, combined with multiple LTE, or 5G, carriers in the sub-6 GHz bands. Additionally, the built-in measurement computer improves R&D productivity with its easy-to-use touch-screen interface for measurement control and monitoring.
According to Bluetest Product Manager Klas Arvidsson, the Anritsu LTE system based on MT8821C has shown stable performance for many years and currently supports 4×4 MIMO and all available LTE carrier combinations up to 6 carriers. The original Bluetest and Anritsu FR1 5G system was presented in October 2018.
Anritsu Marketing Director Hiroyuki Kato adds; “Using the MT8000A, MT8821C, 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.”
