RADIO DEVICES AND METHODS FOR CONTROLLING RADIO DEVICES

摘要

PURPOSE: A wireless device and wireless communication device are provided to secure the interference of a restricted level and to minimize an interference level. CONSTITUTION: A signal projector(602) transmits a signal of the predetermined intensity. A response receiver(604) receives a response message about a signal that is transmitted from a wireless communication device. The response message is a message to identify the received message. A testing circuit(606) evaluates the reachability of the wireless communication device based on the intensity of the signal.
