| Short Description | Wireless M‑Bus is a European standard (EN 13757‑4) designed for low‑power, short‑range wireless communication between utility meters and data collectors. It operates in several license‑free sub‑GHz bands and supports multiple communication modes optimized for different ranges, data rates, and energy requirements. It is widely used in smart metering for water, gas, heat, and electricity, enabling automated consumption reading and reliable long‑distance transmission through buildings. |

Wireless M‑Bus is a European standard (EN 13757‑4) designed for low‑power, short‑range wireless communication between utility meters and data collectors. It operates in several license‑free sub‑GHzGigaHertz (GHz) 10^9 Hz bands and supports multiple communication modes optimized for different ranges, data rates, and energy requirements. It is widely used in smart metering for water, gas, heat, and electricity, enabling automated consumption reading and reliable long‑distance transmission through buildings.
Purpose: remote meter reading and data collection in smart metering systems. Frequencies: mainly 868 MHzMegaHertz (MHz) 10^6 Hz, 433 MHzMegaHertz (MHz) 10^6 Hz, and 169 MHzMegaHertz (MHz) 10^6 Hz, depending on the mode and region. Network type: typically a low‑power star network with up to thousands of nodes per collector. Modes: S, T, C, N, F, each offering different trade‑offs in range, data rate, and power consumption.
Wireless M‑Bus has become the most common wireless metering technology in Europe thanks to its combination of efficiency, reliability, and flexibility.
