Radiocrafts Launches World’s First OMS Compliant Wireless M-Bus RF Module for Smart Meters
Norway, 2009-09-28 -- Radiocrafts AS, a leading provider of compact RF modules, now expand their product
line with a new firmware feature set (MBUS3) complying with the OMS (Open Metering System) specification. The new
firmware runs on the industry leading Wireless M-Bus module (RC1180-MBUS) for use in Automatic Metering Reading
(AMR) applications. This is the first all-embedded module solution compliant with the new OMS specification
available in the market, and comes in addition to the well established NTA 8130 compliant feature set (MBUS2).
OMS primary communication interface is based on the Wireless M-Bus standard (EN 13757-4:2005) and specifies the
communication between a Multi Utility Communication (MUC) controller or gateway, and electricity, gas, water and
heat meters. The specification is becoming widely accepted in Europe as a basis for new Advanced Metering
Infrastructure (AMI) installations. Radiocrafts has participated in the development of the new specification
together with leading meter manufacturers and other communication technology providers in Europe.
MBUS3 module can be configured for use as a master (in the MUC), a slave (in the meter or an actuator), or as a
repeater. The module supports S1, S2, T1 and T2 modes, handles encryption (AES-128), and all time-critical
communication between the MUC and the meter. The power saving features gives battery lifetimes in excess of 14
A master module can support up to 64 slaves, all with unique encryption keys. The master has a unique auto-message
generation feature and message mailboxes supporting individual communication with several slaves in parallel.
The repeater functionality makes up a complete and autonomous repeater that will store and retransmit slave
messages in order to increase the coverage area of one master (MUC). The new RC1180-MBUS3 is a surface-mounted
high performance transceiver module measuring only 12.7 x 25.4 x 3.3 mm, and can easily be integrated into any
meter. A UART interface is used for serial communication and configuration. An antenna is connected directly to
the RF pin. The new module supports two-way communication, enabling not only meter reading but also valve control
and data acknowledgement.
The RC1180-MBUS module is certified for operation under the European radio
regulations for license-free use. When used with quarter-wave antennas a line-of-sight range of 800 meter can be
achieved. “By launching the first OMS compliant module in the market, we have again demonstrated our
technological leadership in embedded wireless solutions for Smart Meters. The emerging AMI market and the new OMS
specification have created a huge demand for this product. Short time-to-market is now vital for meter
manufactures to position themselves in the rapidly growing Smart Metering market. The MBUS3 module is then the
perfect solution, and we are already supplying large pilot customers”, says Peder Martin Evjen, Managing Director.
“Meter manufacturers, system integrators and AMI providers can now get a complete Wireless M-Bus solution
compliant with the OMS specification in a small compact module form-factor that is easy to integrate into meters
and gateways. The industry leading Wireless M-Bus stack makes it easy to add a fully compliant OMS solution to
space limited and battery operated meters, and significantly reduce time-to-market, development and compliance
testing cost”, says Tom Sjølie, Sales and Marketing Director.
The module and Demo Kits are available now.
