Title: WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, AND WIRELESS DEVICE
Abstract:
A wireless communication system (1) is provided with: a first wireless device (20), which is to be introduced into a living body, and which has an antenna; and a second wireless device (10) that communicates with the first wireless device (20) via the antenna. In the cases where the first wireless device (20) is positioned outside of the living body, the wireless communication system (1) uses a first frequency in communication between the first wireless device (20) and the second wireless device (10) via the antenna, and in the cases where the first wireless device (20) is positioned inside of the living body, the wireless communication system uses, in the communication, a second frequency that is lower than the first frequency.
