Abstract

The invention discloses a WiFi (Wireless Fidelity) optical fiber radio central control system which comprises a controller, n radio-frequency signal distribution units and n radio-frequency branches, wherein each radio-frequency branch comprises a second combiner / shunt, a circulator, an electro-optical conversion module and an optical-electro conversion module; each radio-frequency signal distribution unit comprises a first combiner / shunt, n radio-frequency switches and a radio-frequency interface connected with the first combiner / shunt, and one ends of the n radio-frequency switches are connected to the first combiner / shunt, while the other ends are respectively connected to the n second combiners / shunts; and all the radio-frequency switches are independently controlled by a controller. The invention combines a radio-frequency switching technology, an optical fiber subcarrier multiplexing (SCM) technology and an optical fiber radio technology, and realizes the distribution, the switching and the optical fiber distribution of WiFi radio-frequency signals.

Description

WiFi fiber optic radio central control system technical field The present invention relates to a WiFi fiber optic radio central control system, in particular to a controller, a radio frequency signal distribution unit, a combiner / splitter, a circulator, an electrical / optical conversion module (E / O), an optical / electrical conversion module (O / E ). The WiFi radio frequency signal distribution, routing and optical fiber distribution are realized through the WiFi fiber optic radio central control system, which is used for intelligent, large-scale and flexible distribution of WiFi signals. Background technique At present, WiFi wireless local area network is becoming more and more popular, and has become the first choice for establishing a wireless local area network. However, the signal coverage range of a common WiFi access point (AP) is: indoors, 50-100 meters; outdoors, 100-150 meters. In order to expand the coverage of WiFi signals, the main methods adopted are: increasi...
