Short range de­vices

Short range devices (SRDs) comprise a wide and varied range of technologies for voice and data transmission, including non-specific short range radio equipment, movement detectors, social alarms, inductive applications, active medical implants, animal implants, low power FM transmitters, wireless audio applications, radiodetermination applications, tank level probing radars, model control, radio frequency identification (RFID), and road transport telematics. All of these radio applications are used in many areas of daily life (garage door openers, weather stations, baby monitors, remote controls, etc). Such applications are very attractive in particular because they can be freely used by anyone without a special frequency assignment free of charge. However, this leads to a rapid growth in continually new applications for which mechanisms need to be standardised in order to be able to guarantee efficient use of the frequencies available for SRDs into the future.
