Radio frequency signal dynamic coverage system and method using wireless laser communication as carrier

Abstract

The invention discloses a radio frequency signal dynamic coverage system and method using wireless laser communication as a carrier, at least including a base station, a movable access point and a terminal user. The base station modulates the radio frequency signal on the wireless laser signal and sends it to one or more On the mobile access point, the mobile access point moves freely within a certain range; after the mobile access point receives the wireless laser signal, it converts it into a wireless radio frequency signal and sends it to the end user; the base station and the mobile access point All are equipped with positioning and tracking subsystems to realize two-way wireless laser communication; the movable access point dynamically adjusts its own position and the output radio frequency beam according to the number and position of end users to realize dynamic coverage of radio frequency signals; the present invention uses wireless laser Communication is the carrier, free from the constraints of traditional optical fiber communication, so that the RF coverage area can be dynamically adjusted. While maintaining the high speed and high bandwidth of the optical carrier RF system, the coverage of the system is expanded and the flexibility of the system is improved.

AI Technical Summary

Problems solved by technology

[0002] The traditional radio frequency over optical technology combines the advantages of large bandwidth of light and the flexibility of radio frequency wireless access. It has the advantages of small size, light weight, low loss, anti-electromagnetic interference and high transmission quality, and can solve the problems existing in traditional microwave transmission systems. Large loss, weak anti-interference ability and other problems

However, the traditional RF-on-fiber technology is based on optical fiber transmission signals, and its optical link position is relatively fixed and cannot be adjusted dynamically. Moreover, the coverage area of ​​RF signals must be based on the wiring design of optical fibers, which limits the coverage and freedom of RF.
