Description

Computer Communication System for Telephone Network Wireless Access

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer communication system for wireless connection of a telephone network, and more particularly, to a computer communication system for wireless connection of a telephone network for connecting a modem to a handset of a wireless telephone or for wirelessly transmitting and receiving a modem signal to a telephone.

Modem is a device that can communicate by using a general telephone terminal, and a function that modulates, demodulates, and transmits an analog signal and is widely used in a personal computer.

Conventional communication using a computer is performed by signal transmission in both directions through a modem, and the modem is installed in a computer or internally and is configured to be connected to a telephone terminal by wire.

As such, communication was possible in an environment in which a modem and a telephone terminal were connected by wire, and when a computer was to be moved, there was an inconvenience of installing a telephone terminal separately.

Therefore, conventionally, when installing a computer to use communication through a modem, there is a problem that the installation position is limited depending on the position of the telephone terminal.

SUMMARY OF THE INVENTION An object of the present invention is to provide a computer communication system for wireless connection of a telephone network in which signal transmission between a telephone terminal and a modem is made wirelessly to enable computer communication.

A computer communication system for a telephone network wireless connection according to the present invention for achieving the above object is, a radio unit for performing radio transmission and reception of a signal for communication with the main body of the telephone and a signal for performing signal conversion for connection between the radio unit and the modem A conversion unit is provided in the portable device of the radiotelephone.

In addition, a computer communication system for wireless communication of a telephone network according to the present invention includes a first radio unit connected to a modem to wirelessly transmit and receive a communication signal, and a second radio unit to wirelessly transmit and receive a communication signal to and from the first radio unit. 2 is provided with a signal conversion unit for performing a signal conversion to be transmitted and received by the radio unit and a switching unit for selecting any one of the communication signal and the general call signal input and output to the signal conversion unit and connected to the telephone network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the use of a wireless telephone as a first embodiment according to the present invention, and FIG. 2 is a detailed block diagram of FIG.

As shown in Fig. 1, a modem 12 is connected to a computer 10, a portable device 14 of a wireless telephone is connected to the modem 12, and the portable device 14 of the wireless telephone is a wireless telephone. It will be transmitted and received wirelessly with the main body 16 of. Hereinafter, the configuration of the first embodiment will be described in more detail with reference to FIG. 2.

The wireless telephone portable device 14 includes a signal processor 24 for recognizing and processing respective signals by a key matrix 18 for dialing, a transmitter 20 for receiving a voice, and a receiver 22 for receiving a voice signal. The signal processor 24 is connected to a wireless unit 26 that transmits and receives wirelessly to the main body 16 of the wireless telephone.

The modem 12 for modulating and demodulating the signal is connected to the computer 10, and the output signal of the modem 12 is input to the signal conversion unit 28 and converted into a signal for recognition by the radio unit 26. The signal conversion unit 28 of the radio telephone portable device 14 is configured to be connected to the radio unit 26.

In the first embodiment according to the present invention configured as described above, the wireless unit 26 constituting the portable device 14 of the radiotelephone can be recognized by the signal conversion unit 28 to which the signal of the modem 12 is input. This is done by converting to a signal with an appropriate frequency. The signal wirelessly transmitted from the radio unit 26 is received by the main body 16 of the radiotelephone and transmitted through a telephone terminal (not shown) connected to the main body.

It is also natural that reception operates in the reverse order of the series of transmission processes.

Figure 3 is a block diagram showing a wired telephone using a second embodiment according to the present invention, Figure 4 is a detailed block diagram of FIG.

As shown in the configuration of FIG. 3, a modem 32 is connected to the computer 30, and a first wireless unit 34 is connected to the modem 32 to wirelessly transmit signals of the modem to the wired telephone 36.
