EMITE has launched the very first OTA (over the air) test system capable of simultaneously testing 5G FR1 sub-6 GHz frequencies (from 3 to 6 GHz) with FR2 mmWave frequencies (24 to 110 GHz).
The new 5G SA/NSA FR1+FR2 OTA test bed is based on the 3GPP-permitted Compact Antenna Test Range (CATR) OTA test method, achieving unheard-of capabilities for OTA testing of 5G NR Standalone (SA) or Non-Standalone (NSA) carrier aggregation (CA) or dual-connectivity (EN-DC). The new 5G SA/NSA FR1+FR2 OTA test bed has been developed at the EMITE 5G Lab in Cartagena, Spain.
Key Highlights of the Test System:
- The new test bed makes use of EMITE OTA CATR small-size test systems.
- With excellent 15 um peak-to-peak manufacturing accuracies, the modified-design serrated-edges reflector and feed-source for the H285 Compact Antenna Test Range is now capable of providing uniform wavefronts for frequencies from 3 to 110 GHz.
- With 30 and 60 cm Quiet Zones, the new test bed achieves < 0.5 dB and /±2 degrees amplitude/phase ripples.
- Customers can now benefit from fast, effective and realistic 5G OTA laboratory tests for 5G combinations of sub-6 GHz and mmWave frequencies.
The use of FR1 frequencies are limited to 3 to 6 GHz at the tested design for now, and EMITE is already manufacturing a patented design capable of testing the full 5G frequency range. With just about 3 x 2 x 2 m, the small-size compact antenna test range outperforms any existing model in the market, providing excellent both amplitude and phase uniformity for a relatively large quiet zone.
They showcased this product at Mobile World Congress America 2018 last week.
