What is BS EN 13757-4 - Wireless M-Bus communication for meters about?
BS EN 13757-4 is the fourth part of the EN 13757 multi-series, which covers communication systems for meters. This European standard promotes the use of wireless meter communication systems in utility services so the user can charge their clients accurately.
BS EN 13757-4 specifies the requirements of parameters for the physical and the link-layer for systems using radio to remotely read meters. The primary focus is to use the Short-Range Device (SRD) unlicensed telemetry bands. BS EN 13757-4 encompasses systems for walk-by, drive-by and fixed installations. As a broad definition, BS EN 13757-4 can be applied to various application layers.
Who is BS EN 13757-4 - Wireless M-Bus communication for meters for?
BS EN 13757-4 on wireless M-Bus communication for meters is useful for:
- Power supplying organizations
- Organizations that provide gas
- Water supply department
Why should you use BS EN 13757-4 - Wireless M-Bus communication for meters?
The meter communicates with one (or occasionally several) fixed or mobile communication partners which again might be part of a private or public network. These further communication systems might use the same or other application layer protocols, security, privacy, authentication, and management methods.
BS EN 13757-4 concentrates on meter communication. BS EN 13757-4 provides you guidance on the necessary requirements to implement a wireless meter communication system. BS EN 13757-4 informs you about the channels and their frequencies that can be used by these metering devices to remotely transmit consumption data.
Overall, the guidance of BS EN 13757-4 enables you to implement an efficient wireless meter communication system that provides real-time data so you can execute the billing process remotely and accurately.
