CTIA Approved 5G mmWave Take a look at System with Multi-AoA Capabilities in FR2


Rohde & Schwarz has cooperated with the US-based CTIA group to authorize the primary a number of angles of arrival (multi-AoA) check system for CTIA OTA efficiency certification. The answer relies on the profitable conformance check system R&S TS8980 whereas additionally leveraging the R&S CMX500 5G tester along with the R&S ATS1800M mmWave (FR2) chamber from the superior chamber portfolio from Rohde & Schwarz.

5G NR mmWave know-how will witness the adoption of latest, complicated applied sciences similar to beamforming, refined antenna array programs and a brand new usable communications spectrum. For FR2, each machine must be examined over the air (OTA), with none cable connections. Many superior 5G NR functions additionally depend on ultra-high knowledge charges and ultra-low latencies. Each are solely accessible in FR2. The check answer from Rohde & Schwarz is tailor-made to deal with these necessities and options. Certification by CTIA is the door-opener for validating 5G gadgets together with FR2 frequencies for machine producers and community operators within the US, and a acknowledged stamp of approval worldwide.

The certification of cell gadgets towards widespread requirements is without doubt one of the most essential cornerstones of guaranteeing their interoperability. Rohde & Schwarz is the primary check and measurement provider approved by the CTIA to produce these certification checks in a 5G FR2 check system that additionally affords full multi-AoA capabilities. Multi-AoA is crucial for verifying the efficiency of cell gadgets within the mmWave area, as radio waves at these excessive frequencies (e.g. 28 GHz) endure from excessive path loss and due to this fact must be centered in slender beams which might be difficult to seek out, observe and hand over whereas transferring.

The brand new check system is similar superior check platform that just lately achieved the trade’s first Take a look at Platform Approval Standards (TPAC) for RRM 5G NR FR2. Scalable from 30 to 40 cm quiet zone, from Single AoA to Multi-AoA and from in-band to out-of-band – the check system is already ready for superior testing challenges. These embrace phantom testing with the two-hand panorama, single-hand portrait and head testing, for which specification work is ongoing at CTIA. Moreover, help for the upcoming check necessities from 3GPP releases 16, 17 and 18, is being deliberate, giving clients the boldness to spend money on a future-proof platform.

Dr. Thomas Eyring, Director of Cellular Gadget Certification at Rohde & Schwarz, says, “We’re proud to help CTIA’s endeavours to speed up the roll-out of wi-fi connectivity broadband throughout the US and past. With our appreciable expertise in over-the-air testing with the newest 5G mmWave merchandise, we have been in a position to create a number one check system to cowl the complete certification wants for RF and RRM. This provides clients the distinctive alternative to totally automate the RF and RRM certification testing course of on a single check system, protecting OTA efficiency checks from CTIA in addition to checks outlined by 3GPP and GCF.”
