Document Type and Number:
WIPO Patent Application WO/2006/064651
Kind Code:
A1
Abstract:
There are provided a radio tag communication device and a radio tag communication system capable of obtaining effective linkage without generating communication superposition. The radio tag communication system includes: a position relationship judgment unit (74) for judging a relative position relationship of a plurality of radio tag communication devices (12); and a transmission control unit (76) for controlling transmission of a transmission signal from each of the radio tag communication devices (12) according to the judgment result by the position relationship judgment unit (74). Accordingly, it is possible to obtain a sufficient time interval required for transmitting a transmission signal by adjacent radio tag communication devices (12). That is, it is possible to provide the radio tag communication system (10) capable of preferably performing effective linkage without causing communication superposition.
