WMBus

WHAT IS W-MBUS ?

W-MBus, for Wireless-MBus, is an evolution of the European Mbus standard, in a radio frequency adaptation.

It is widely used by professionals in the energy and utilities sector. The protocol has been created for metering applications in industry as well as in the domestic sector.

Using unlicensed ISM frequencies (169MHz or 868MHz) in Europe, this connectivity is dedicated to metering and metering applications: water, gas, electricity and thermal energy meters are the typical uses provided by this protocol.
