This study explores the capabilities and performance of Device-to-Device (D2D) communication within the 5G network framework, focusing on the DECT NR+ standard. Developed by the European Telecommunications Standards Institute (ETSI), DECT NR+ aims to meet the stringent requirements of 5G technology. The hypothesis assumes that DECT NR+ can significantly enhance communication efficiency and reliability in D2D scenarios. To test this hypothesis, hardware and software tools from Nordic Semiconductor was utilized, including the nRF9161 Development Kit, nRF Connect for Desktop and nRF Connect SDK. These tools facilitated the setup and evaluation of seamless communication between devices using the DECT NR+ standard. Key performance metrics were systematically evaluated, including latency, coverage, Packet Success Rate (PSR), data rate, and power consumption.
