Silicon Laboratories and IMST, a supplier of wireless communications technology, have unveiled a turnkey wireless M-Bus solution designed for the smart energy market.

The comprehensive hardware/software solution combines IMST’s technology with Silicon Labs’ Si10xx wireless microcontroller (MCU) technology to simplify the deployment of ultra-low-power, high-performance, pre-certified wireless M-Bus modules for smart meters.

IMST’s iM871A wireless M-Bus module offers a cost-effective RF solution for smart metering applications connecting water, heat, electricity and gas meters with data concentrators in the 868MHz frequency band.

Using Silicon Labs’ Si1002 wireless MCU, the iM871A module can achieve a link budget up to 120dB when operating in R2 mode, resulting in exceptional RF range and communications performance.

The iM871A module has an exceptionally small footprint, comes equipped with a serial interface as well as analog and digital inputs and outputs to accommodate interfaces with a customer’s system and is fully compliant with the EN 13757-4 standard.

The module supports all major unidirectional and bidirectional wireless M-Bus modes (S1, S2, T1, T2 and R2) in addition to all tolerance specifications, enabling the highest possible flexibility in metering environments.
