Keysight Technologies, Inc. enabled Quectel to verify that its internet of things (IoT) wireless modules support the latest 5G reduced capability (RedCap) and non-terrestrial networks (NTN) features by establishing end-to-end data call connections using the Keysight S8711A UXM 5G Test Application. This achievement accelerates Quectel's development of 3GPP 5G Release 17 (Rel-17) compliant designs.
Based on the 5G Rel-17 specification, RedCap introduces support for a new class of 5G devices with reduced 5G capabilities. These devices are less complex, lower cost, and consume less power, allowing them to address new use cases such as industrial sensors and wearables. The successful end-to-end RedCap data connection to the Quectel module Rx255C was made by emulating a 5G Rel-17 network with enhancements supporting RedCap devices.
NTN, based on satellite-to-ground communication, brings secure and reliable connectivity to remote areas that do not have terrestrial network coverage. Use cases for NTN deployments include industrial IoT, mission-critical and emergency communications, and connected vehicles. The successful end-to-end NTN connection was made to the Quectel modules CC660D-LS and CC950U-LS by emulating a constellation of satellites in geostationary orbits (GEO), which worked in transparent mode delivering a satellite network.
