Internet of Things (IoT) chip vendor Silicon Labs has introduced a Wireless M-Bus platform for smart meters in the European electricity, gas, water, and heat resources market.
The open Wireless M-Bus protocol is geared toward deploying wireless connectivity solutions for smart metering and smart grid applications. The wireless platform includes an M-Bus software stack and wireless starter kit to speed time-to-market and works with Silicon Labs’ ARM-based microcontrollers and sub-GHz wireless ICs. The platform is based on the EN13757-4/3 European standard to meet the communication needs between smart utility meters, data concentrators, mobile readout devices and heat cost allocators.
As more smart meters are requiring longer battery life, Silicon Labs says the M-Bus protocol requires little overhead for the small amounts of data used by meters, enabling battery life of up to 15 to 20 years.
Silicon Labs adds that the Wireless M-Bus platform covers all region-specific requirements throughout Europe and the software stack complies with the Wireless M-Bus specification, the Wireless M-Bus Application Layer and the Application Layer of the Open Metering System Group. It also supports modes at 868 MHz and 169 MHz from the physical layer to the application layer, according to the company.
