Abstract:
1. A wireless communication system that includes first and second information communication terminals with built-in IC chips engaged in alternating wireless communication with each other through noncontact communication, wherein: said first information communication terminal includes: a reception unit that receives a packet originating from the second information communication terminal; a transmission unit that wirelessly transmits a plurality of packets to the second information communication terminal by transmitting in succession all packets that can be transmitted to the second information communication terminal continuously in a batch if a specific condition is satisfied; an interval calculation unit that calculates a transmission interval with which the plurality of packets are to be transmitted, based upon communication-related information corresponding to the first information communication terminal and communication-related information corresponding to the second information communication terminal; wherein the transmission unit transmits the plurality of packets continuously in the batch based upon the calculated transmission interval; and an identifier appending unit that appends a last packet identifier to a packet to be transmitted last from said transmission unit among all the packets that can be transmitted to the second information communication terminal continuously, wherein upon receiving a last packet identifier from a transmission unit of the second information communication terminal, the first information communication terminal judges that the last packet from the second information communication terminal signals a timing with which the plurality of packets should be sent to the second information communication terminal without sending an acknowledgement of receipt of packets to the second information communication terminal.
