Wireless M-Bus

European standard for RF communication link between flow meters, electric meters and the data collecting devices.

What is Wireless M-Bus?

Wireless M-Bus (wM-Bus) is a low-cost, low-power star network running on license-free industrial-scientific-medical bands. Based on Sub-1 GHz, wM-Bus can reach through concrete walls and long distances, with networks of as many as 1,000 nodes per collector. There are modes for the 868-MHz, 433-MHz and 169-MHz bands, enabling coverage over several kilometers. wM-Bus is the most common wireless metering standard for Europe.
