Technical Overview

This repository contains an experimental implementation of the DECT-2020 NR (DECT NR+) protocol stack based on the ETSI TS 103 636 Standard Version 2.1.1 targeted at Nordic Semiconductor's nRF9161, nRF9151 and nRF9131 System-in-Packages (SiPs) utilizing the Nordic modem PHY firmware (mfw-nr+_nrf91x1_1.1.0), This library covers Parts 4 & 5 of the specification.

Architecture

The implementation includes:

• DECT NR+ MAC Layer

  • MAC state machines (Fixed Part & Portable Part)
  • Physical layer control and interface
  • Data path management
  • Security framework
  • Timeline and synchronization utilities
  • Management entity handlers

• DECT NR+ Stack API

  • Unified interface for application integration
  • State management and callbacks
  • Configuration and control interfaces

• Network Driver

  • Zephyr RTOS integration
  • Nordic Connect SDK compatibility

Prerequisites

• Nordic Connect SDK v3.x
• Zephyr RTOS
