dedicated short-range communication



  • A technology in which RF signals are emitted by an object in response to an interrogator, for purposes of identification, collection of information, or the like. A typical arrangement involves a reader which emits signals which a transponder, or tag, in the object responds to. The reader, which processes the obtained information, and tag need not be in nearly direct contact, as is required, for instance, in a bar-code system.
  • A system using dedicated short-range communication (1). Such a system may be utilized, for example, to identify store items being purchased or placed into inventory, to drive through a toll station having the appropriate amount automatically deducted from a smart card attached to the windshield, for the location, complete with proper placement instructions, of parts within a robotic assembly line, or for tracking the movements of people being spied on by attaching such devices on clothing, objects being carried, or via the surgical insertion or embedding of such transceivers. Higher-frequencies, greater transmission power, and enhanced antenna designs, for instance, may be utilized to extend the range of such systems.
