Description

High speed internet communication line wireless access device and connection method {A connecting apparatus for an ADSL telecommunication line and the method

The present invention relates to an ADSL communication line connection method and a connection device, and more particularly, to a method and a connection device capable of wirelessly connecting a plurality of terminals to one subscriber line.

In offices, banks, and public offices, office automation has increased the use of telecommunications equipment. Accordingly, the user has increased the number of lines of subscriber lines (aka telephone lines) used for smooth use of equipment. Several communication devices had to be connected to the track and each device had to be used at different times. However, because increasing the number of lines on a line introduces high costs and complexity, users have generally preferred to connect multiple communication devices on a single line, which is inefficient because each device must be used at a different time. It was. Thus, so far, there have been many studies to utilize one subscriber line.

In order to effectively utilize subscriber lines, telephone lines, fax machines, and computer communication terminals must be connected together in a single line so that they can be used appropriately without collisions, and they can move with each other and do not cause interference to each other.

xDSL (x Digital Subscriber Line) is a generic name for transmission technology that provides high-speed data transmission service while guaranteeing the use of existing Plain Old Telephone Service (POTS) by using higher frequency bands not used among the frequency bands of general telephone network. will be. In other words, the use of POTS by the existing copper cable is limited to the frequency band of 3.4 KHz or less within 1 MHz, which is a part of the transmission capacity. Therefore, the high speed data communication service is used by using the unused band of the existing copper telephone network. The technology that makes this possible is xDSL.

xDSL has been developed in various ways such as ADSL (Asymmetric DSL), SDSL (Symmetric DSL), HDSL (High bit rate DSL), VDSL (Very high data rate DSL) according to transmission method, speed and distance. It is used to provide high speed multimedia services such as distance education and video phone.

There is a growing interest in ADSL service among xDSL. The reason why ADSL is attracting attention is because it can easily provide high-speed communication service such as multimedia to general users. In other words, ADSL provides a maximum speed of 56kbps and PSTN service provides a maximum speed of 128kbps. Because of its ability to provide a maximum downstream speed of 7Mbps or more and an upstream speed of 640kbps or more, users who are dissatisfied with the previous communication speed and seek high-speed communication services have attracted much attention.

In addition, SDSL and HDSL do not support data communication service and voice call service at the same time, and VDSL has a disadvantage in that the transmission distance for providing a service is very short. Although it is difficult to extend the distance by using, the ADSL is able to provide voice call service and ADSL data communication service at the same time, considering the effect of investment and the effectiveness of the service. It is emerging as a technology that can easily provide high-speed services through investment.

However, simultaneous use of a plurality of terminals requires as many subscriber lines as there is a problem of increasing the complexity and cost of the facility. As shown in FIG. 1, the multi-subscriber line method by wire has a problem in that it is particularly expensive because the number of subscriber lines must be increased in proportion to the number of voice and data terminals used.

A method of jointly using several terminals in one subscriber line has been proposed, but it has a problem such as speed degradation and poor call quality due to voltage drop through a wired connection. In addition, this technology has a problem that the voice terminal or the data terminal cannot be moved to another place because the xDSL modem and the data terminal interconnect data cable must always be in the same position.

An object of the present invention is to provide a method and an access device that allows a plurality of terminal users to use high-speed Internet by using one subscriber line.

Features of the access method according to the present invention for achieving this object are the process of separating the voice signal and the data signal in one subscriber line, the process of frequency conversion of the separated data, the process of wireless transmission using an antenna and And receiving the frequency signal at a plurality of terminals such as a PC located in a predetermined region, and converting the frequency into a data signal to access the high-speed Internet.

A detailed feature of the connection method according to the present invention is that the radio signal transmitted over a certain distance through the antenna is a short wave.

Another detailed feature of the access method according to the present invention is that the bandwidth of the radio signal is adjusted to increase the number of available terminals in the corresponding frequency band.

The configuration features of the Internet access device according to the present invention is a splitter for separating voice and data signals in one subscriber line, a first frequency converter for converting data provided by the splitter into a frequency, and the first frequency converter A mother computer system having an antenna for transmitting a signal provided therethrough within a predetermined area;

A plurality of computer systems are provided with an interface including a frequency receiver for receiving a frequency signal provided through the antenna, and a second frequency converter for converting the received frequency into a data format.
