Abstract

To provide a wireless communication system and a wireless communication method including: a first terminal apparatus comprising a computer main body and a second terminal apparatus comprising a displaying section, wherein the two terminal apparatuses perform wireless communication with each other without communication crossing. A management center obtains the positional information of a first terminal apparatus, and then records the positional information. The management center determines a communication channel free from communication crossing, depending on the positional information. The communication channel determined by the management center is transmitted to the first terminal apparatus. The first terminal apparatus and a second terminal apparatus perform wireless communication with each other through the received communication channel.

Claims

1. A wireless communication system comprising a first terminal apparatus and a second terminal apparatus, wherein

said first terminal apparatus comprises:

a position detecting section for detecting the positional information of said first terminal apparatus;

a computer for generating image information; and

a first wireless communication section for transmitting said image information to a third wireless communication section of said second terminal apparatus through a first communication channel defined depending on said positional information; and

wherein

said second terminal apparatus comprises;

said third wireless communication section for receiving said image information; and

a displaying section for displaying said image information.

2. A method for controlling a wireless communication system comprising a first terminal apparatus and a second terminal apparatus, said method comprising:

position detecting step in which said first terminal apparatus detects the positional information of said first terminal apparatus;

image information generating step in which said first terminal apparatus generates image information;

wireless communication step in which said first terminal apparatus transmits said image information to said second terminal apparatus through a first communication channel defined depending on said positional information;

wireless communication step in which said second terminal apparatus receives said image information; and

displaying step in which said second terminal apparatus displays said image information.
