Oslo, Norway — (METERING.COM) — May 12, 2008 – Radiocrafts AS has now expanded its product line with a compact wireless M-Bus RF module for use in automatic metering reading (AMR) applications – the first compact all-embedded module compliant with the new Wireless M-Bus standard available in the market.

The Wireless M-Bus standard (EN 13757-4:2005) specifies the communication between water, gas, heat and electricity meters or concentrators. It is becoming widely accepted in Europe as a basis for new advanced metering infrastructure (AMI) installations.

The RC1180-MBUS RF transceiver module is a compact surface-mounted high performance module measuring only 12.7 x 25.4 x 3.3 mm including shielding, replacing tens of components compared to a discrete design. The module is delivered on tape and reel for volume production.

It is easy to use, having a UART interface for serial communication and configuration, and a one-pin antenna connection. The new module supports two-way communication, enabling not only meter reading but also valve control and data acknowledgement. It meets the Wireless M-Bus specification for all S1/2, T1/2 and R2 modes, and operates at 12 channels in the 868 MHz frequency band.

The RC1180-MBUS module is pre-certified for operation under the European radio regulations for license-free use. When used with quarter-wave antennas a line-of-sight range of 500-600 meter can be achieved. It is designed for use in battery operated systems with up to 20 years of battery lifetime.

"By launching the first wireless M-Bus module we have again demonstrated our technological leadership in embedded wireless solutions," says Peder Martin Evjen, Managing Director. “The emerging AMI market and the new standard has created a huge demand for this product, and we are already working with large pilot customers.”
