Method for transmitting 3G wireless signal based on cable TV network

Abstract

The invention discloses a method for transmitting a 3G wireless signal based on a cable TV network, which comprises the following steps that: a 3G signal is transmitted to a signal combiner through a cable; the signal combiner combines a cable TV signal and the 3G wireless signal into one path of signal to send the signal to a cable TV network cable, wherein the 3G signal is subjected to impedance matching before signal combination or the transmission of the combined signal to the cable TV network cable to adapt the 3G signal to cable TV network cable transmission so as to transmit the 3G signal through the cable TV network cable; and before the combined signal arrives at terminal equipment of the cable TV network, a signal separator is used for separating the 3G wireless signal and the cable TV signal and transmitting the 3G wireless signal and the cable TV signal respectively to realize the cable TV signal and the coverage of the 3G wireless signal to use functions and services provided by the 3G in a room. The method has the advantages of realizing the large-scale coverage of the 3G wireless signal, along with simple structure, reliable signal reception, and great reduction in the installation number of 3G equipment and the installation construction difficulty.

Description

technical field [0001] The invention relates to a method for transmitting wireless signals of the third generation public mobile communication system (abbreviated as 3G) through a cable television network. Background technique [0002] With the development of 3G services, it is a difficult problem to provide stable 3G wireless signals in buildings, especially in rooms for people to live in. The current solution is mostly to install 3G antennas in these buildings, so that the wireless signal can pass through the obstacles in the middle to reach the relevant location. In doing so, a larger number of antennas must be installed than in the GSM communication system of the second generation, and the signal quality cannot be guaranteed at the same time. Since more antennas are installed, it not only affects the aesthetics of the decoration, but also needs to lay more cables, which also increases the difficulty of construction. Contents of the invention [0003] In view of the a...
