Embodiment Construction

[0020] The basic idea of ​​the present invention is: the present invention integrates the application of traditional satellite communication and WIFI base station. Compared with the expensive satellite terminal for each user of traditional satellite communication, the system saves the purchase and installation costs of the terminal and improves the traditional satellite communication. The use efficiency and broadband utilization rate reduce operating costs and provide new market impetus for satellite communications. The system can achieve several kilometers of long-distance links through MESH long-distance hopping technology to form another long-end coverage, and the system coverage can be expanded without the need for new satellite links.

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 As shown, a WIFI application system based on satellite communication includes a gateway station, a communicat...

Abstract

The invention discloses a WIFI (wireless fidelity) application system based on satellite communication. The system mainly comprises a gateway station, a communication satellite transponder, a satellite terminal and a WIFI base station, wherein the gateway station is used for realizing functions of receiving and transmitting data of a satellite feed link, managing network resources, managing an operating system and the like; the communication satellite transponder is used for realizing a function of transponding data of a satellite user link and the data of the satellite feed link; the satellite terminal is used for realizing a function of receiving and transmitting the data of the satellite user link; the WIFI base station is used for realizing a wireless receiving and transmitting function for data of a user link; the satellite feed link is a communication link between a satellite and the gateway station; the satellite user link is a communication link between the satellite and the satellite terminal; the user link is a communication link between the WIFI base station.

Description

technical field [0001] The invention relates to a WIFI application system based on satellite communication, which belongs to the field of satellite communication. Background technique [0002] Today's society has entered the information age, and people's demand for information exchange has become increasingly strong, to the point where it is indispensable. In my country's large and medium-sized cities and economically developed areas, the coverage of terrestrial broadband networks can reach almost 100%. However, in economically underdeveloped areas, especially in remote mountainous areas, villages, or some specific emergency sites, the network is often not covered or the network is damaged, resulting in poor or interrupted communication. Satellite communication has become an effective way to solve this problem, but the disadvantages of traditional VSAT satellite communication, such as high operating cost, difficult installation and maintenance, and low frequency band utiliz...
