Problems solved by technology

However, traditional lasers also have some weaknesses, such as: limited line of sight, communication interruption caused by occlusion or bad weather; difficult to aim, and the laser beam has extremely high directionality, so it is necessary for the transmitter and receiver to aim More accurate instruments, and the operation is also very complicated; the laser emission power needs to be limited within the safe range, if you need to emit high-power laser, you must have other safety protection measures

Abstract

The invention relates to a wireless communication device based on a distributed optical resonant cavity. The device comprises a master and a slave. The master comprises a master optical antenna, a master main control module and a master modulation module. The slave comprises a slave optical antenna, a slave main control module, a slave optical detection module and a slave demodulation module. Themaster optical antenna and the slave optical antenna form an optical resonant cavity. A resonant beam is formed in the optical resonant cavity. The master main control module selects the optical pathof the master optical antenna, and at the same time the master main control module sends the information to the master modulation module. The master modulation module controls the master optical antenna to modulate the resonant beam. The slave optical detection module detects transmission light led out from the slave optical antenna and sends the detection information to the slave demodulation module for demodulation. The slave demodulation module sends the demodulation information to the slave main control module. Communication from the master and the slave is completed. Compared with the prior art, the wireless communication device provided by the invention has the advantages of no alignment, high communication capacity and minimal interference.

Description

Technical field [0001] The invention relates to a wireless communication device, in particular to a wireless communication device based on a distributed optical resonant cavity. Background technique [0002] According to the Cisco Visual Networking Index (VNI) report, wireless business traffic will increase by nearly 100% every year in the future. In the next ten years, wireless data traffic will increase by 1,000 times. Especially in the future, AR / VR and other applications will generally increase. The demand for will increase significantly. Therefore, mobile devices urgently need to increase the transmission capacity of communication devices. Traditional communication methods include 3G / 4G cellular mobile network, WIFI, Bluetooth, etc. Generally, the downlink bandwidth of the 4G standard can reach 100Mbps, and the downlink bandwidth of different standards for WIFI is different. Generally, 802.11g can reach 54Mbps. The Bluetooth transmission rate is generally 1Mbps. In addit...
