Wireless gateway for smart metering

26 November 2008 Telecoms, Datacoms, Wireless, IoT

Radiocrafts and Wavecom have teamed up for the launch of a new GSM/GPRS/EDGE gateway for smart metering which embeds Wireless M-Bus and ZigBee, all in a compact form factor.

The Wireless M-Bus standard (EN 13757-4:2005) specifies the communication between water, gas, heat and electricity meters and concentrators, whereas ZigBee is a standard for monitoring and control applications using low-power radio networking.

The new solution is based on Wavecom’s Fastrack Supreme, a programmable application processor with GSM/GPRS/EDGE modem capabilities. The Fastrack Supreme comes with an open-standard interface which allows developers to add supplementary I/O connectivity and features in the form of expansion cards. Radiocrafts has developed a unique expansion card for smart metering which adds Wireless M-Bus or ZigBee to the GSM/GPRS/EDGE communications function.

The expansion card embeds Wireless M-Bus (868 MHz) or ZigBee (2,4 GHz, including high power) on interchangeable PCBs. Both versions of the card connect via a UART serial interface to the RTOS driven host controller in the Fastrack Supreme. The gateway enables manufacturers of smart metering solutions to develop devices operating on various RF networks with little design effort.

Customers can either purchase a ready-to-use expansion card from Radiocrafts, or buy only the Wireless M-Bus or ZigBee module and create their own card.
