July 30, 2020 Perry Cohen

Keysight Technologies announced it was first to gain validation of 5G universal subscriber identity module (USIM) protocol conformance test cases at the conformance agreement group (CAG) #63 meeting led by the Global Certification Forum (GCF) on July 10, 2020.

USIM is included within 5G devices to assure secure authentication of users, network access, and subscription models. The GCF-validated 5G USIM protocol conformance test cases allow device and module makers to verify the USIM complies to the standards that are set by the 3rd Generation Partnership Project (3GPP).

"Early access to validated 5G USIM protocol conformance test cases enable a connected 5G ecosystem to speed delivery of 5G services that rely on advanced security, reliability and subscription models," said senior director of Keysight's wireless test group Muthu Kumaran, in a press release. "Integrating USIM and USIM application toolkit (USAT) capabilities within Keysight's device test solution eliminates the need for a separate SIM simulator, leading to quick and easy testing of a device's performance across various technologies."

During the meeting, it was stated that the company’s 5G conformance toolset offers the industry’s largest number of GCF validated 5G new radio (NR) radio frequency (RF) and protocol test cases.
