Keysight Technologies and MediaTek have used Keysight’s 5G test platform to establish 5G connectivity based on 3GPP Release 16 (Rel-16) specifications and verified features of 3GPP technical enhancements and improvements including frequency range 1 and range 2 carrier aggregation, (FR1+FR2 NR-CA), new radio-new radio dual connectivity and others.
Shortly after the global standards organization 3GPP finalized the Rel-16 specifications, the two companies worked together to achieve physical player interoperability development testing (IODT). MediaTek used their latest M80 5G modem and Keysight's 5G Protocol R&D Toolset to establish the link based on Rel-16, which offers enhancements including increased coverage, capacity, mobility and reliability, as well as lower latency and improved power efficiency to 5G new radio (NR) deployments.
The latest M80 5G modem combines mmWave and sub-6GHz 5G technologies into a single chip to support ultra-fast data speeds.
“Joining forces with a global fabless semiconductor company with leading 5G technology, enables Keysight to support an expanding ecosystem with 5G test solutions for verifying compliance to specifications mandated by 3GPP and mobile operators," said Cao Peng, vice president and general manager for Keysight's wireless test group.
3GPP Rel-16 brings enhancements to existing Rel-15 features such as dynamic spectrum sharing (DSS), multiple input multiple output (MIMO) and carrier aggregation (CA), improving coverage, capacity, latency, power consumption, mobility and reliability. Rel-16 also leverages unlicensed spectrum, satellite communications, downlink-based positioning and integrated access, as well as backhaul (IAB), helps drive the industry towards realizing the vision of smart city, industrial internet of things (IIoT) and autonomous vehicles.
MediaTek also used Keysight's 5G Protocol Conformance Toolset to validate the protocol signaling performance of the company's M80 5G modem. The toolset offers the industry's most comprehensive support for 5G protocol test cases validated by either GCF or PTCRB, a certification forum led by representatives from leading U.S. mobile operators.
