Abstract
A wireless communication system includes code transmitters (20a, 20b) each configured to transmit a time-varying code; code receivers (30a, 30b) each configured to receive the time-varying codes transmitted from the code transmitters (20a, 20b) and generate a fingerprint based on the received time-varying codes, the fingerprint being unique to a space where the time-varying codes are receivable; and terminal devices (40a, 40b) configured to establish wireless communication connection therebetween with authentication. The terminal devices (40a, 40b) are connected to the code receivers (30a, 30b), respectively. Each terminal device (40a, 40b) includes a fingerprint acquiring unit configured to acquire the fingerprint from the code receiver (30a, 30b), a wireless communication unit configured to transmit and receive the fingerprint via wireless communication, and an authentication unit configured to authenticate another terminal device if the fingerprint received from the another terminal device matches the fingerprint acquired from the code receiver connected thereto.
