Wireless M-Bus module

10 November 2010 Telecoms, Datacoms, Wireless, IoT

Telit Wireless Solutions is launching a new module featuring wireless M-Bus transfer technology. The ME50-868 supports uni- and bi-directional RF connections at 868 MHz between meters for gas, water, heating or electricity and concentrators. This exchange of data forms the basis for the use of smart meters which increase the accuracy and transparency of bills, offer better customer service and help improve energy efficiency.

The device’s 122 dB budget link provides a range of up to 2000 m. The modules with LGA (land grid array) mounting technology operate with ultra-low power (<1 μA in standby), resulting in long battery life and low maintenance requirements. Equipped with an RS232 interface and digital as well as analog inputs and outputs, the modules can be integrated into a variety of systems. The ME50-868 is pin-to-pin compatible with the Telit modules in the ZE (ZigBee 2007 and PRO stack), NE (mesh low power) and LE (basic point-to-point, broadcast stack) families. It is also compliant with EN 13757 part 4 and part 5.

M-Bus is a standardised transfer technology for the remote reading of meters inside buildings. When the transfer is made by radio, the technology is referred to as wireless M-bus. The frequency range used, from 868 MHz to 870 MHz, offers the widest range inside buildings. The data from the individual meters is transferred to a concentrator on site, which collates and transfers it via the Internet or a telephone network to the supply companies. Telit also provides a gateway solution (GG863-SR) that integrates short range and GSM/GPRS capabilities.

Smart metering is already being successfully used in Italy, Scandinavia, the Netherlands, North America and Australia. In Germany, from 2010 onwards, new buildings are required to be equipped with smart meters, and from 2018 this will apply to all buildings. The aim is to encourage consumers to be more energy-conscious by giving them detailed and real-time information about their energy usage.
