ANRITSU CORPORATION announced its New Radio RF Conformance Test System “ME7873NR” to have achieved PCS Type Certification Review Board (PTCRB) certification for the first time *A in test cases related to non-terrestrial networks (NR NTN) utilizing 5G technology, using Samsung’s NR NTN modem chipset.
The NTN is a communication system that integrates satellite communication and airborne technologies along with terrestrial infrastructure, leveraging satellites in low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary Earth orbit (GEO).
3GPP Release 17 introduces “NR NTN”, which includes Non-Terrestrial Networks into the 5G New Radio (NR) standards. With this advance, 5G devices can connect to satellites using the same protocols as terrestrial base stations, paving the way for global 5G coverage beyond traditional infrastructure.
The PTCRB definition of NR NTN testing signifies the formal commencement of the NTN device certification process. Going forward, NR NTN is expected to be actively adopted by network operators worldwide to enhance service quality and expand coverage. Anritsu will contribute to the proliferation of NTN devices by providing certification test systems.
Product Overview
The ME7873NR is a 3GPP-compliant 5G RF conformance test platform certified by both the Global Certification Forum (GCF) and PCS Type Certification Review Board (PTCRB). It supports Frequency Range 1 (FR1, Sub-6 GHz) out-of-the-box, and combining it with an OTA (CATR) chamber * adds support for Frequency Range 2 (FR2, mmWave).
