DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an amateur radio apparatus for the Internet and an amateur radio system for the Internet using amateur radio as a communication medium for connecting the Internet to a computer.

[0002]

2. Description of the Related Art Conventionally, a computer network (hereinafter simply referred to as a "network") in which a plurality of computers are connected by a communication line or the like to store and exchange data and programs among the plurality of computers and to share data and the like. Say) is built.

[0003] As a method of such a network,
An open network system that allows computers to be freely connected as a general rule if it conforms to a predetermined communication protocol, etc., and the network is managed by a host computer, etc., and certain restrictions such as security are imposed on terminal devices such as connected computers. There is a closed network system in which an unmanaged computer node is not connected to the network.

The Internet is a typical example of the above-mentioned open network system. In this Internet, the communication protocol is TCP (Transfer
Control Protocol) / IP (Internet Protocol) is adopted. In principle, any computer that complies with this communication protocol can be connected to a network.

[0005] In recent years, with the background of a free network environment such as the Internet, WWW (World Wide W
eb) and other multimedia environments have been developed. In particular, recently, many Internet businesses (e-businesses) that provide specific services using the Internet have been proposed and operated.

As a method for personally using the Internet, a user individually contracts with an Internet service provider (ISP), which is an Internet connection provider, and uses a telephone line or the like to access points provided by the ISP. It is common to use the Internet by connecting.

[0007] Recently, the connection fee for the ISP and the telephone line usage fee have also been set to a non-quantitative fixed-rate system, so that the cost of the connection fee (Internet usage fee) can be suppressed to some extent.

[0008]

However, in the use of the Internet as described above, the fixed amount system of the ISP connection fee and the telephone line usage fee has become widespread in an area where the communication infrastructure has been sufficiently developed. However, there is a problem that these systems cannot be used if there is no ISP access point in an area where the user can use the telephone line usage fee in an unlimited amount.

For this reason, there is a problem that the cost of using the Internet for a user who does not have an ISP access point in a non-quantitative fixed-rate area is still high, and the Internet cannot be sufficiently used.

[0010] Accordingly, an object of the present invention is to provide an amateur radio apparatus for the Internet and an amateur radio system for the Internet that can use the Internet at low cost without considering the communication fee to the access point.

[0011]

In order to solve the above-mentioned problems, an amateur radio apparatus for the Internet according to the present invention comprises:
An amateur radio apparatus for the Internet for connecting a computer to the Internet using amateur radio as a communication medium, a radio transmitting / receiving means for transmitting / receiving amateur radio data, a computer interface means for transmitting / receiving data to / from a computer, and a computer interface Data conversion means for converting the digital data received from the means into an amateur radio signal and outputting it to the radio transmission / reception means, converting the amateur radio signal received from the radio transmission / reception means into digital data and outputting it to the computer interface means, It is characterized by having.

According to another aspect of the present invention, there is provided an amateur radio system for the Internet according to a first aspect of the present invention, wherein a computer is connected to the Internet, and data communication between the computer and the Internet is performed by an amateur radio. Perform.

According to a second aspect of the present invention, there is provided an amateur radio system for the Internet, wherein the computer is connected to the Internet using the amateur radio as a communication medium. An amateur radio access point that is connected to a computer and converts an amateur radio signal into digital data that can be communicated on the Internet, and converts digital data that can be communicated on the Internet into an amateur radio signal, and is connected to a computer and processed by a computer An amateur radio device for converting possible digital data into an amateur radio signal and converting the amateur radio signal into digital data which can be processed by a computer. In between scan points and Internet for amateur radio device transmits and receives data to amateur radio signals, characterized in that.

By using amateur radio as a communication medium between the computer and the Internet, it is possible to keep the Internet usage fee low without increasing the communication cost.
