An object is to provide a communication system in which there are no restrictions on a communicable area and it is not necessary to install communication software on a wireless device. A communication system according to the present invention is configured so that the functions of a wireless access point are separated into a front-end unit on a wireless terminal side and a back-end side on the Internet side, radio signal processing functions supporting a wireless scheme of the wireless terminal are deployed only on the back end, and only relatively simple processing functions such as E/O conversion are deployed on the front end near the wireless terminal

Communication system

The present disclosure aims to make it possible to simultaneously establish communication between many freely-selected radio terminals without using a complex relay network or a plurality of radio relays. The present disclosure is a communication network system including: a plurality of optical-radio converters-to-that convert a radio signal and an optical fiber radio signal into each other; and a path controller that is connected to the plurality of optical-radio converters-to-through optical fiber transmission lines-to-, receives input of an optical fiber radio signal transmitted from any optical-radio converter of the plurality of optical-radio converters-to-from the optical fiber transmission line connected to the optical-radio converter, and outputs the optical fiber radio signal to the optical fiber transmission line connected to a set optical-radio converter of the plurality of optical-radio converters-to-
