Introduction
DECT NR+ represents a new generation of wireless technology designed to address the growing connectivity requirements of industrial, infrastructure, building automation, and professional audio applications. Built on modern wireless principles and operating in the globally harmonised 1.9 GHz DECT spectrum, DECT NR+ combines reliable communication, low latency, scalable network architectures, and open-standard interoperability.
Unlike many existing wireless technologies that were designed for a specific market segment, DECT NR+ aims to provide a common wireless foundation capable of supporting diverse applications ranging from smart meters and industrial sensors to intelligent buildings and professional audio systems.
The Drivers Behind DECT NR+
Several major trends are creating new requirements for wireless communications:
- Electrification and renewable energy integration
- Industrial digitalisation
- Smart buildings and infrastructure automation
- Growth in connected devices
- Increasing demand for low-latency wireless control
- Need for long-term, standards-based deployments
Many existing wireless solutions struggle to simultaneously provide:
- Scalability
- Reliability
- Low operational cost
- Global deployment capability
- Long product lifecycles
- Open interoperability
DECT NR+ was developed to address these challenges.
The Evolution of Energy Networks
Electricity networks are undergoing a fundamental transformation.
Traditional power systems were largely centralised, with electricity flowing from large power stations to consumers. Modern energy systems are becoming increasingly decentralised, with renewable generation, battery storage, electric vehicles, and local energy production all contributing to the grid.
This transition creates a growing need for:
- Real-time monitoring
- Remote control
- Distributed sensing
- Reliable communications
- Large-scale device connectivity
Smart meters and advanced metering infrastructure form a critical part of this digital energy ecosystem.
Why DECT NR+ Fits Smart Metering

Utility Control and Governance
Utilities maintain direct ownership of the communications infrastructure rather than relying on external network operators.
This provides:
- Greater operational control
- Easier integration with utility systems
- Long-term deployment flexibility
- Improved business sovereignty
Lower Total Cost of Ownership
Because devices share a common communications architecture:
- Product development is simplified
- Certification can be streamlined
- Network maintenance is reduced
- Long-term operational costs remain lower
Buildings Are Becoming Intelligent Systems
Modern commercial buildings increasingly rely on connected systems to improve:
- Energy efficiency
- Occupant comfort
