Wireless communication system
First Claim
1. A wireless communication device for performing bi-directional communication with a remote communication device using a frequency hopping method, the device comprising:
- a frequency changing unit changing a frequency, at which communication is performed;
a communication unit performing communication at the changed frequency for a holding time;
a holding time length controlling unit controlling a length of the holding time and controlling the communication unit to perform communications at the changing frequency for the controlled holding time; and
a holding time inputting unit allowing a user to input the user'"'"'s desired value as the length of the holding time, the holding time length controlling unit changing the length of the holding time into the user'"'"'s inputted value.

Abstract
A wireless communication device for performing bi-directional communication using a frequency hopping method, in which the communication time at any one frequency can be varied. The user uses the dial to adjust the length of time during which a single frequency is used. Accordingly, if the volume of data is large, as in image data, the communication time can be increased. If the volume of data is small, as in voice data, the communication time can be decreased. If privacy is desirable, the communication time is decreased, whereas increasing the communication time will increase the transfer rate. Such settings can be made manually by the user to suit the user'"'"'s needs, or can be made automatically based on the type of data being transferred.
