Description

System for connecting a desktop computer or notebook computer to internet by wireless technology}

The present invention relates to a system for converting and transmitting data in order to use the wireless Internet, and more particularly, to a wireless internet connection system for relaying a wireless internet to be used in a laptop or desktop computer that is currently widely used. .

With the development of computer communication technology, the Internet is becoming popular. Since the Internet is mainly using a wired line (telephone line or leased line), the behavior is limited, and even when using a high-speed leased line, there is a problem that the speed drops. In other words, when using the telephone line used at home, the communication speed is so slow that it is almost impossible to use it for business and it is not helpful for learning at all.

In addition, the use of high-speed leased line is gradually increasing, but problems such as poor connection and slowing down are occurring. In addition, as the data communication speed of communication companies that advertise to provide high-speed leased lines has been found to be very low, consumer complaints are increasing rapidly.

The wireless Internet is being developed to solve this problem. Since the wireless Internet does not use a telephone line or a dedicated line itself, the data transmission speed is stable and high speed can be used. In addition, since it can be used in any place regardless of time and place, its use is increasing in terms of business.

Hereinafter, the wireless Internet connection system of the present invention will be described in detail with reference to the accompanying drawings.

Wireless Internet connection system of the present invention can enjoy a wireless Internet service at home or a company at a low cost, more convenient to access and operate than the existing wired Internet, there is no need to purchase a conventional high-priced wireless Internet terminal, and the cost is low It is easy to connect, can use high speed internet, and it is easy to popularize because of low production method and cost.

2 is a schematic connection state diagram of a wireless Internet connection system according to the present invention.

As shown, it can be seen that the wireless Internet connection system 5 according to the present invention is connected to a general desktop PC 4 (or a notebook computer). The wireless Internet connection system 5 has a wireless data transmission / reception function with the base station 3 as in the related art, and has a built-in device for language conversion by itself.

Wireless Internet connection system 5 can be configured in the form of parabolic antenna as shown in the drawing has the advantage of easy installation. Furthermore, the necessary devices can be installed in the lower support structure of the antenna. The desktop PC 4 equipped with the wireless Internet connection system 5 of the present invention can easily connect the Internet as in the conventional wired Internet, and can enjoy data communication at a higher speed than wired.

3 is a connection state diagram including a schematic block diagram of a wireless Internet connection system 5 according to the present invention. The signal output from the conventional desktop PC 4 becomes a signal according to a communication protocol (TCP / IP, which is an Internet communication rule). The signal output from the desktop PC 4 is input to the language conversion server 53 embedded in the wireless Internet connection system 5. The language conversion server 53 converts the input data into a wireless markup language (WML), which is a grammar used in the wireless Internet in the conventional htm (l) syntax.

The web page data converted by the language conversion server 53 is wirelessly propagated through the antenna 51 after being modulated into a radio signal by the modulation and demodulation device 52. The antenna 51 may use an antenna used in a mobile phone, and may use a parabolic antenna, which is a directional antenna, in case of wireless communication using a satellite. Of course, it is also possible to use other types of antennas, and having a parabolic antenna form has the advantage of easy antenna installation. Modulation and demodulation device 52 serves as a conventional mobile phone.

The radio signal including the Internet data information propagated through the antenna 51 is received by the base station 3 as is conventionally transmitted to the Internet provider to process the necessary data. After the data is processed, a signal including Internet data information transmitted to the desktop PC 4 is also wirelessly propagated through the base station 3. The data processing in the base station 3 is the same as the wireless Internet connection using a conventional mobile phone. As described above, the data transmission process from the desktop PC 4 to the base station 3 is described in the flowchart of FIG. The base station 3 uses a wireless internet data processing scheme, commonly known as WAP.

The radio signal transmitted from the base station 3 is received via the antenna 51. The received data is demodulated in the demodulation device 52. The demodulated data may be demodulated in text form as data containing Internet information. The data demodulated by the modulation / demodulation device 52 as described above is input to the language conversion server 53. The input data is data created by WML syntax. WML syntax is a grammar system used in the case of the WAP method.

The language conversion server 53 converts the data based on the input WML grammar into htm (l) grammar that can be recognized by the desktop PC 4 and outputs it. The output web page data is input to the desktop PC 4, and is output on the screen after being analyzed by the web browser. In this way, the wireless Internet data created by the WML grammar can be output on the screen of the desktop PC 4. This process is described in the flowchart of FIG.

The language conversion server 53 is to convert one grammar to another grammar, and may be implemented by replacing specific characters or commands with characters or commands used in different grammar systems, or adding or deleting additional commands. It can be produced programmatically. However, it is desirable to use hardware to achieve high speed.

Figure 4 shows another embodiment of a wireless Internet connection system of the present invention.

It has a structure similar to that of FIG. 3, but there is a difference in the language conversion server 63. In other words, the language conversion server 53 in Fig. 4 converts the htm (l) syntax into c-htm (l) syntax, which is based on this, but is another grammar system. c-htm (l) is known as W3CCI mode. Reference numeral 62 is a modulation and demodulation device and functions the same as 52. 61 is also the same as 51 as an antenna.

In the above description, the htm (l) grammar is converted to WML, c-htm (l), etc., but it is obvious to those skilled in the art that the present invention can be converted to other wireless Internet writing languages. Or modifications also belong to the scope of the present invention. This is actually accomplished by making the conversion server adaptable for each grammar system.

The wireless Internet connection system according to the present invention can be used by connecting to a desktop PC or a notebook PC in a home. In addition, because it can be connected to a desktop PC or a laptop PC at work, it is excellent in mobility and can promote the spread of the Internet.

In addition, it is a new technology that can overcome the inconvenience of using the existing wired Internet because it can conveniently use the high-speed wireless Internet. In addition, since the connection system, which is a wireless transmitting and receiving device, can be installed outdoors or at a place far from a user, there is no need to worry about harmful electromagnetic waves.

As described above, according to the present invention, the price is low, so that the wireless Internet can be operated and utilized in a general home, and high-speed Internet connection is possible, the connection cost is low, and the connection is easy, without subscribing to a dedicated Internet line or a specific communication company. Can also use the phone and high-speed Internet at home at the same time, the production method or equipment is simple and has the advantage that can achieve the maximum effect at the minimum cost.
