Wireless M-Bus

Designed for meter reading in Europe, the Wireless Mbus protocol is an adaptation of the wired Mbus standard. This protocol is widely used in the energy sector for Machine to Machine (M2M) data transmissions. The Wireless Mbus protocol is particularly known for the quality of its radio coverage, the easy association between other technologies and the simplicity of deployment and installation of the equipment.


On the two product ranges developped by Enless Wireless on the Wireless Mbus protocol, the communication is made from point to point (non-operated). The Wireless Mbus protocol allows to build your private network. The transmitters periodically send data frames that are received by a Modbus receiver generally connected to a PLC or a gateway. The Modbus receiver stocks the transmitters’ data frames in its table, then the PLC reads the values that are stocked in the Modbus Table. Free choice is given regarding the way to process data.



Enless Wireless proposes two complete product ranges on the Wireless Mbus protocol. One product range that works with 868MHz frequency band and another on the 169MHz frequency band. These radio frequencies are licensed-free and their use is harmonized to the entire European Union.


868MHz and 169MHz Wireless Mbus technologies are energy consumption efficient. The battery life of the transmitters can exceed 15 years.


The 868MHz and 169MHz product ranges differ in terms of performances.
