1. A wireless communication system comprising:
a wireless base station apparatus; and
a wireless terminal apparatus that performs RF wireless communication with the wireless base station apparatus using continuous light from the wireless base station apparatus for authentication,
wherein the wireless base station apparatus comprises:
a light generation circuit that generates continuous light having a predetermined characteristic;
a beam controller that controls a beam shape of the continuous light from the light generation circuit, and sends out the continuous light into space;
a base station-side RF receiver that receives authentication information from the wireless terminal apparatus by RF wireless; and
an authentication control circuit that permits information communication between the wireless terminal apparatus and an upper network when authenticating the wireless terminal apparatus according to a predefined authentication protocol based on the authentication information from the base station-side RF receiver, and
the wireless terminal apparatus comprises:
a light receiver that receives the continuous light from the beam controller;
a continuous light determination circuit that determines the predetermined characteristic of the continuous light received by the light receiver;
an authentication information database circuit that selects authentication information according to the determination by the continuous light determination circuit;
an authentication execution circuit that executes the predefined authentication protocol based on the authentication information from the authentication information database circuit; and
a terminal-side RF transmitter that transmits the authentication information from the authentication execution circuit to the base station-side RF receiver by RF wireless.
