Narrow-Band Telemetry Systems

At a glance

Systems for wireless data communication are becoming increasingly widespread in industrial and home automation. They typically take the form of narrow-band telemetry systems and are used to transmit sensor data and control information across simple networks. Fraunhofer IIS's RF and Communications Departments have worked closely to develop this technology for narrow-band, long-range wireless data transfer.

 

Technical description

The 868 MHz band permits particularly efficient channel coding and so enables operating ranges up to ten times those of standard wireless systems. The transmitters used, which are based on inexpensive commercial radio chips from manufacturers like Chipcon or Silabs, are small and ensure long battery life. The receivers are equipped with digital signal processors and, thanks to their flexible design, can be adapted to customer requirements. They are suitable for both stationary and mobile use and can be optimized for either.

 

Application

Uses range from transmitting switch status information, for instance for lighting control, to machine-to-machine (M2M) communication to wireless remote meter reading and consumption control in smart metering applications. Further possible applications include monitoring of large-scale installations or facilities, collection of data from environment sensors in hard-to-reach places, and transmission of vital signs data acquired from athletes or emergency responders.
