Abstract:
A system intended to eliminate erroneous operations of the vibrator, a drawback of mobile terminals of the conventional independent vibrator method. The system comprises communication mobile terminals capable of communicating with other terminals through radio communication while they are moving; and peripheral devices designed to perform predetermined operations through radio communication between the mobile terminals and the peripheral devices. For radio communication between the mobile terminals and the peripheral devices, the apparatus employs time division multiplexing that exchanges signals by carrying data in time slots. In the time division multiplex, the mobile terminals use time slots of time bands other than those that the mobile terminals use for sending radio signals to base stations to send radio signals to the peripheral devices. This allows the mobile terminals to send radio signals to the peripheral devices without being interfered with by the radio signals transmitted by the mobile terminals to the base stations.
