The RC11x0 M-Bus RF Transceiver Module is a compact surface-mounted high performance module with embedded Wireless M-Bus (Meter-Bus) protocol for wireless AMR | AMI. Versions of the Wireless M-Bus module works on different frequencies including 433, 868, and 902-928 frequency bands, but using the link and application layer of EN 13757-4. The module has a UART interface for serial communication and configuration and a one-pin antenna connection. Further features offered by the RC11x0 M-Bus are AES-128 encryption/decryption and auto-acknowledge with a patented message mailbox feature

The module measures only 12.7 x 25.4 x 3.3 mm with shielding. When used with quarter-wave antennas, a line-of-sight range of over 800 meters can be achieved. The module supports S, T and R2 modes, and operates in 12 channels in the frequency bands.  EN 13757-4 is an open standard which aims for equipment interoperation and has dedicated modes optimized for battery operated devices. The network topology is point-to-multipoint or peer-to-peer.

The RC11x0 M-Bus RF Transceiver Module also complies with the OMS standard (Open Metering Standard) in use in Europe.
