Abstract

본 발명은 컴퓨터와 컴퓨터간의 원거리 데이타 통신을 가능하게 하는 모뎀에 관한 것으로, 특히 컴퓨터와 모뎀을 무선으로 연결하여 위치 이동에 제약이 없도록 한 외장형 모뎀의 무선 연결 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modem for enabling remote data communication between a computer and a computer, and more particularly, to a wireless connection system of an external modem for connecting a computer and a modem wirelessly,

즉, 본 발명은 무선 전화기의 고정 장치와 휴대 장치를 각각 컴퓨터와 모뎀에 연결하여 모뎀과 컴퓨터 간의 데이타 통신이 무선으로 가능하도록 하는 시스템을 제공함을 목적으로 한다.That is, it is an object of the present invention to provide a system in which data communication between a modem and a computer is enabled wirelessly by connecting a fixed device and a portable device of a wireless telephone to a computer and a modem, respectively.

이로 인해, 모뎀과 컴퓨터 사이의 데이타 통신이 무선으로 이루어지게 됨으로써 컴퓨터 이동이 편리해지고 또한 전화선의 길이가 짧아지게 되어 큰 사무실에서 매우 효율적이 되며, 무선 전화기 기능이 확대됨으로써 실용성이 향상된다.As a result, the data communication between the modem and the computer is performed wirelessly, so that the computer can be easily moved and the length of the telephone line is shortened, which is very efficient in a large office.
