868MHz wireless M-bus for your METERING application

Supplier: Amber Wireless
Product: Wireless M-Bus Modul 868 MHz
Device: AMB8425-M
Package: SMD Module

The Wireless M-Bus standard (EN13757-4:2005) specifies the communication between water, gas, heat and electricity meters and concentrators. The standard comprises various operating modes (S, T and R) to meet the requirements of one-way and two-way data communication in stationary and mobile systems. The AMB8425-M is an all embedded low-cost wireless M-Bus radio module, which operates in 12 channels in the 868 MHz frequency band. The integrated protocol controls the entire data communication. Data packets are built and transmitted according to EN13757-4:2005 specification. Configuration of parameters is handled via the UART interface and a control pin. The module automatically adds the Manufacturer ID and the Address based on parameters configured in the radio module. Measured field strength (RSSI value) offers the option of enhancing quality of the radio link.

The customised application layer can be fully integrated in the radio module, thus eliminating the need for an external host microcontroller. The radio module supports the AES-128 encryption standard. A very low-power mode ensures long battery lifetime.

The module is pre-certified for operation under the European radio regulations for license-free use. Due to ist outstanding RF characteristics the module achieves a range of up to 700 metres line of sight. The AMB8425-M is a surface-mounted module and is available on Tape &Reel for volume production.
