Full title and description

DIN EN 13757-4:2019-09 — Communication systems for meters — Part 4: Wireless M‑Bus communication. This DIN adoption reproduces EN 13757-4:2019 and specifies the radio (wireless) variant of the M‑Bus system used for remote reading of consumption meters (walk‑by, drive‑by and fixed installations).

Abstract

This part of EN 13757 defines the physical layer and the link (data‑link / MAC) layer parameters for wireless meter reading systems (Wireless M‑Bus). The standard targets operation in Short Range Device (SRD) unlicensed telemetry bands and sets requirements to support interoperable radio telegram formats, timing, addressing and medium access for walk‑by, drive‑by and fixed reading scenarios.

Scope

Specifies requirements and parameter values for the physical and link layers of radio‑based meter reading systems using the Wireless M‑Bus protocol. Primary focus is on use within SRD (Short Range Device) unlicensed telemetry bands and on enabling interoperability for walk‑by, drive‑by and fixed automatic meter reading (AMR) deployments. The document is intended to be used together with other parts of the EN 13757 series that specify wired M‑Bus lower layers and application layer protocols.

Key topics and requirements

• Radio physical layer parameters (frequency bands, channel spacing, modulation and symbol rates) tailored for SRD telemetry use.
• Link layer framing, addressing, sequence handling and telegram formats to ensure interoperability between devices and collectors.
• Medium access and timing rules for walk‑by, drive‑by and fixed installations (including duty cycles and retransmission behavior).
• Requirements to support relaying and network extension where applicable (complements EN 13757‑5 relaying provisions).
• Performance and coexistence considerations for operation in unlicensed bands (power limits, receiver sensitivity guidance, and interference mitigation best practices).

Typical use and users

Used by meter manufacturers, radio module and chipset vendors, utility communications engineers, system integrators, certification and test laboratories, and consultants designing or deploying automatic meter reading (AMR) and smart‑metering solutions that rely on Wireless M‑Bus for data collection. Also used by utilities planning walk‑by, drive‑by or fixed network rollouts and by procurement teams specifying compliance requirements.

FAQ

Q: What is this standard?

A: EN 13757‑4:2019 (published in Germany as DIN EN 13757‑4:2019‑09) is the European standard that defines the physical and link layer requirements for Wireless M‑Bus — the radio variant of the M‑Bus protocol used for remote meter reading.

Q: What does it cover?

A: It covers radio‑level parameters (frequency, modulation, data rates), link‑layer telegram and addressing formats, timing and medium access rules, and operational profiles for walk‑by, drive‑by and fixed AMR deployments operating in SRD unlicensed telemetry bands. It is intended to be used with other parts of EN 13757 that define application protocols and relaying.

Q: Who typically uses it?

A: Meter and module manufacturers, utilities, system integrators, test labs and consultants working on smart‑meter deployments that require a standardized wireless communication link for meter reading and telemetry.

Q: Is it current or superseded?

A: The DIN EN 13757‑4:2019‑09 edition documents the EN 13757‑4:2019 text; however, a newer German edition (DIN EN 13757‑4) was published in February 2026, which updates the national publication. Users should check the most recent national/EN catalogue or their national standards body for the currently designated valid edition before procuring or certifying equipment.

Q: Is it part of a series?

A: Yes — it is Part 4 of the EN 13757 series (Communication systems for meters). Other relevant parts include EN 13757‑2, EN 13757‑3 and EN 13757‑5, among others, which together define wired and wireless lower layers, application profiles and relaying.

Q: What are the key keywords?

A: Wireless M‑Bus, M‑Bus, SRD, AMR, telemetry, physical layer, link layer, EN 13757, DIN EN 13757‑4.
