Description

Technical Field [0001] The present invention relates to an emergency communication system using a smart device based on a satellite network and an emergency communication method using the same,

The present invention relates to an emergency communication system using a smart device based on a satellite network and an emergency communication method using the same. More particularly, the present invention relates to a portable satellite communication device, an antenna for wireless data communication connected thereto, The present invention relates to an emergency communication system and an emergency communication method that enable a smooth communication service when a ground communication network and a wired / wireless communication network can not be used due to an emergency such as a disaster, a disaster, a war or an accident.

The terminal of the VSAT device which transmits and receives the satellite communication signal which is generally used is a dedicated terminal for transmitting / receiving the satellite signal and mainly uses the frequency of 12 to 4 GHz. GlobalStar (Globalstar) and Inmarsat (global satellite service) are available, and local satellite service is provided to provide global satellite communication service through interworking with conventional global satellite network. The development of mobile communication devices and the investment of terrestrial broadcasting equipment have caused the roaming service among the countries and the demand for the satellite communication service has not been so much and it is used only for the special purpose limited to the service in the marine communication or the remote area Is being recognized. In comparison with terrestrial mobile communication, public awareness is low and the burden on users' usage costs and the development of devices such as recently popularized smart devices are lacking. And uses only the exclusive equipment of the company providing the satellite communication service. Therefore, in order to use the satellite communication service, the satellite communication terminal is purchased or rented so that the price or function But the competitiveness is falling. Such a satellite communication terminal has a high frequency band different from an authorized frequency band used by existing terrestrial terminals and is generally used in the range of 12 to 14 GHz and has a large difference from the 900 MHz to 2 GHz frequency band for terrestrial mobile communication, Satellite radio waves can not be used as a mobile terminal for mobile communication with a receiving antenna of a frequency band. In addition, in the saturation phase, the satellite frequency bands, which are currently in use, have entered a competition for technology development and frequency securing to utilize the higher frequency band of 20 to 30 GHz. In order to use the signal of the high frequency band, a satellite antenna of about 1 m in size or a large antenna of 18 to 20 m in size of the transmitting and receiving antenna should be mounted on the satellite itself, and a dedicated satellite receiving chip and a high- An antenna that can be utilized should be embedded in a terrestrial mobile communication terminal or the like. In addition to having a satellite reception chip and a high-frequency antenna installed in the mobile communication terminal, a satellite communication service provider or a user using the satellite communication service provider needs additional investment costs because it is necessary to install a large satellite for smooth transmission and reception. And it is difficult to see it as a realistic method because it takes long time to invest in technology development. Currently, satellite broadcasting is received through satellite-based outdoor fixed-satellite antenna, SET-TOP BOX and display output device. However, if it is necessary to evacuate in case of emergency, Broadcasting and communications use expensive satellite transit vehicles, but this is mainly due to the broadcast-based broadcasting equipment installed in private vehicles such as broadcasters, which is a limit to move vehicles in the event of an emergency in the event of a disaster or a disaster . If road facilities are damaged or destroyed, it may not be possible to move to isolated areas.
