Is achieved through the location and radio frequency triangulation determines the expansion of the defense of the RF- tag. The beacon placement is determined from the orientation of the beacon node designed spatially. RF- tag location detection is carried out by such a measurement from the beacon nodes arranged in a plurality of spatially. Beacon nodes having a plurality of antennas, and transmits the frame by the respective symbol periodically switch to a different antenna. Other symbols moving distance to cause a phase shift in the received frame by the RF- tag. From a known arrangement of a phase shift and an RF- antenna angle that the RF tag is possible from a particular node, the beacon can be estimated.
