Abstract
A wireless communication system is provided for establishing wireless communication between a wireless communication apparatus and a battery-driven communication terminal apparatus in which system the power consumption rate of the communication terminal apparatus can be reduced. The wireless communication system includes a trigger signal transmission line for transmitting a trigger signal from the wireless communication apparatus to the communication terminal apparatus, and a data communication line for establishing data communication between the wireless communication apparatus and the communication terminal apparatus. The data communication between the wireless communication apparatus and the communication terminal apparatus is established in response to the trigger signal that is transmitted by the trigger signal transmission line.
