Evaluation of the IMT-2020 Candidate Radio Interface Technology DECT-2020 NR

This paper provides an overview of DECT-2020 NR technology evaluation conducted by the Wireless World Research Forum (WWRF) in the context of IMT-2020 Evaluation Process solicited by the International Telecommunication Union (ITU). DECT-2020 NR, a Radio Interface Technology developed by ETSI TC DECT and DECT Forum, was submitted as an IMT-2020 candidate along with five other technologies. It is applicable in various use cases and markets, with focus on consumer and industrial IoT applications, such as industry and building automation and monitoring. In particular, it is targeting Ultra-Reliable Low Latency (URLLC) and massive Machine Type Communication (mMTC) scenarios, based on decentralized network deployments. The WWRF performed a complete assessment of the technology which included a high-level assessment of services and spectrum capabilities, along with a minimum technical performance requirements analysis for the URLLC and mMTC test environments, based on inspection, analysis and simulation. For assessing characteristics using simulation, i.e., reliability and connection density, an in-house simulation tool was developed. The evaluation study addressed mesh topologies supported by DECT-2020 and proposed several enhancements to the ITU's evaluation methodology, which is defined for cellular topologies only. The technology was found to fulfill all the requirements specified by ITU's evaluation process for IMT-2020.
