  • Patent number: 8295483
    Abstract: A mobile terminal device, a wireless communication unit, a wireless communication system, and a wireless communication method by which 1:N communication can be realized at low power consumption and a CH occupation time can be shortened. After each terminal transmits an authorization request, it performs a carrier sense with the pattern corresponding to the transmission timing and waits for authorization response from a key unit (200). The key unit (200) transmits the authorization response at the timing when the carrier sense timings of a plurality of terminals which are authenticated in response to the authorization request from the terminal are coincident with each other. Accordingly, the key unit (200) performs transmission only to the authenticated terminals at one time, and 1:N communication can be realized at low power consumption.

  • Publication number: 20090179738
    Abstract: A tag reading device can effectively read a plurality of tags. The tag reading device includes a power control unit (109) for controlling an output power of a transmission unit (101) by a control signal so as to transmit transmission data with an output power set by an output power setting unit (108). When a plenty of tags exist in a readable area and identifiers of the gags frequently make collisions, firstly, the output power of the transmission unit (101) is reduced so as to narrow the readable area and suppress generation of collisions. When the number of tags existing in the readable area of a reader (100) and not yet read has become small, the output power of the transmission unit (101) during retransmission is increased and the readable area of the reader (100) is increased and the remaining tags are effectively read.
