Oslo, Norway — (METERING.COM) — April 29, 2011 – A new module using the 169 MHz band for long range automatic meter reading (AMR) has been announced by Radiocrafts AS, as an expansion to their Wireless M-Bus product line.
The module is compliant with the new prEN 13757-4:2011, operating in the new harmonized frequency band for meter reading in Europe.
The combination of VHF frequency, true narrowband operation and high output power, gives superior communication range and coverage even in urban environments. The typical range is 1.5 km in urban areas and 20-40 km in open terrain with quarter-wave antennas.
As the first compact RF module in the market compliant with the new standard, it offers true narrowband performance in a 12.5 kHz channel, and up to 500 mW output power, achieving a link budget of 150 dB. The module support two-way communication at 2.4 and 4.8 kbps in six narrowband channels, and 38.4 kbps in a 50 kHz channel.
The module contains the Wireless M-Bus protocol stack, supporting battery operated meter devices, concentrators and repeaters.
The new RC1700HP-MBUS is a surface-mounted module measuring only 12.7 x 25.4 x 3.3 mm, and is pin compatible with other Wireless M-Bus modules (868 MHz and other frequencies) from Radiocrafts. It only requires two pins for data, two pins for power supply and one pin to the antenna. A UART interface is used for serial communication and configuration. The antenna is connected directly to the 50 ï— RF pin. The RC1700HP-MBUS module is certified for operation under the European radio regulations for license-free use and is CE marked.
“By launching the new compact 169 MHz Wireless M-Bus module in the market, we have again demonstrated our technological leadership in embedded wireless solutions for AMR,” says Peder Martin Evjen, Radiocrafts managing director. “Through our active participation in the standardisation work in CEN we have shown our commitment and contribution to the development of international standards for meter reading, meeting the target of the M/441 mandate.”
