The smart metering platform includes the Wireless M-Bus software stack and wireless starter kits to speed time to market. The platform is portable across the company’s wide array of "energy-friendly" ARM-based microcontrollers (MCUs) and sub-GHz wireless ICs, and it supports all modes for smart metering in Europe including the 169 MHz N modes.
The open Wireless M-Bus protocol provides an established wireless connectivity system for smart metering and smart grid applications. Based on the EN13757-4/3 European standards, Wireless M-Bus specifies seamless sub-GHz RF communication between smart utility meters, data concentrators, mobile readout devices and heat cost allocators.
Wireless smart meter applications require long life for battery-powered meters such as water, gas and heat meters. To address this need, the Wireless M-Bus protocol requires very little overhead for the small amounts of data used by meters, enabling battery life of up to 15-20 years. Proven over the past several years in field tests and deployments in many countries, Wireless M-Bus has become a widely accepted standard for smart metering in Europe.
The Wireless M-Bus platform covers all region-specific requirements throughout Europe. The software stack complies with the Wireless M-Bus specification (EN13757-4), the Wireless M-Bus Application Layer (EN13757-3) and the Application Layer of the Open Metering System (OMS) Group. The stack supports a wide range of modes at 868 MHz and 169 MHz, from the physical layer to the application layer. Supported modes include T1, T2, S1, S1-M, S2, C1, C2, N1 and N2 (a-g), with ultra-fast preamble detection for the N modes without sacrificing RF performance.
