Abstract

The invention belongs to the field of communication technology, and discloses a long-distance wireless laser WIFI communication system and method. The system comprises a first digital optical transceiver, a first optical amplifier, a first wavelength division multiplexer, a first optical antenna, a second optical antenna, a second wavelength division multiplexer, a second optical amplifier, a second digital optical transceiver and a wireless router. The method comprises: transmitting information by using a wireless laser channel to replace a radio channel. The long-distance wireless laser WIFIcommunication system solves the problems that the WIFI signal coverage is small, the bandwidth is insufficient, the transmission security is poor, and the communication signal is susceptible to interference, resulting in signal instability in the prior art, the long-distance WIFI signal coverage is achieved, the wireless WIFI communication bandwidth is improved, and the communication signal is more stable, safer and less delayed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a long-distance wireless laser WIFI communication system and method. Background technique [0002] WIFI is an Internet technology that helps users access email, Web and streaming media, and it provides users with wireless broadband Internet access. At the same time, it is also a fast and convenient way to surf the Internet at home, in the office or on the go, and it is a communication method that is almost inseparable in people's daily life. WIFI hotspot signal radiation power is low and has no effect on human health, but the coverage is generally within 100 meters. [0003] At present, the method of relaying and extending the coverage of WIFI signals is realized through WIFI repeater or wireless bridge technology. Wireless bridge technology is a wireless connection technology for local area networks. It is the product of the combination of wireless radio frequency techn...
