Keysight, MediaTek Set 5G Connectivity to 3GPP Rel-16 Specs

April 7, 2021
Chipset maker uses Keysight’s 5G test platform to deliver modem solutions for smartphones, PCs, and mobile hotspots.

MediaTek, a leading Taiwanese chipset maker, has used Keysight Technologies' 5G test platform to establish 5G connectivity based on 3GPP release 16 (Rel-16) specifications. MediaTek also used the Keysight platform to verify 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.

MediaTek used Keysight's integrated 5G test solutions to validate the chipset maker's latest M80 5G modem, which combines mmWave and sub-6-GHz 5G technologies into a single chip to support ultra-fast data speeds.

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. By leveraging unlicensed spectrum, satellite communications, downlink-based positioning, and integrated access, as well as backhaul (IAB), 3GPP Rel-16 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 (see the figure) to validate the protocol-signaling performance of the company's M80 5G modem. The toolset offers 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.
