Abstract
A wireless communication apparatus automatically disconnects a communication channel between a master device and a slave device when a received electric field intensity becomes lower than a predetermined level, thereby preventing unnecessarily prolonged communication when the field intensity is excessively low. The received field intensity is detected and if in the course of communication, the reception field intensity becomes lower than a reference level a request for confirmation of the communication status is transmitted to the slave device. In accordance with the response from the slave device to the request for confirmation, the wireless channel may be disconnected.
