Wireless meter reading requires communication protocols with little overhead for small amounts of data. The Wireless M-Bus standard (EN 13757-4) specifies the wireless communication between meters for water, gas, heat and electricity, and the data concentrators. As the Wireless M-Bus protocol according to EN 13757-4 has proven in many field tests in different countries, it is a major standard for smart metering not only in Europe, but also in many other regions of the world. For the data transfer defined as primary communication between the actual meters and the data concentrator (e.g. MUC), the currently applicable norm EN 13757-x was identified. It describes the M bus as a physical interface, both hard-wired and wireless, as well as the data protocol. Both the OMS specification and the KNX standard use the norm EN 13757-4 for wireless communication. Both measurement data and data from the building automation sector can be transferred via the same system.
