Problems solved by technology
At present, various operators have already carried out the installation of wireless base stations outdoors, and the main solution to solve the problem of no signal or weak signal for mobile devices indoors is to deploy feeder networks and new equipment such as BBU (BBU full name Building Baseband Unit, Indoor baseband processing unit), RRU (RRU stands for Remote Radio Unit, remote radio frequency module) and other indoor distribution systems, but the transformation involved requires a lot of manpower and material resources
In addition, due to controversial issues such as the limitations of cable laying and the inability to enter the venues that have been handed over, domestic indoor 5G wireless signals have not been fully covered for a long time. At present, indoor 5G signal coverage has become a signal blind area.

The invention provides a 5G signal transmission system based on a coaxial cable. The 5G signal transmission system comprises a signal preprocessing module, a coupler, a distributor and a plurality ofterminal devices. The signal preprocessing module is used for carrying out level adjustment and impedance conversion on the original 5G signal; the coupler is used for carrying out signal coupling onthe processed 5G signal and an original HFC radio frequency signal to form a combined transmission signal; the distributor is used for distributing the combined transmission signal to each terminal device; the terminal device comprises a first output unit and a second output unit. The first output unit is used for filtering out the original HFC radio frequency signal and transferring the originalHFC radio frequency signal to the feeder line; and the second output unit is used for carrying out impedance conversion on the filtered 5G signal and then transferring the 5G signal to the antenna. Byperforming level adjustment and impedance conversion on the original 5G signal, indoor 5G wireless signal transmission can be realized on the basis of a broadcast and television traditional HFC pipeline network, so that the construction cost of an indoor 5G signal transmission system is greatly reduced.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a 5G signal transmission system based on coaxial cables. Background technique [0002] With the popularity of mobile terminals, high-quality wireless access signals are increasingly sought after by users. At present, various operators have already carried out the installation of wireless base stations outdoors, and the main solution to solve the problem of no signal or weak signal for mobile devices indoors is to deploy feeder networks and new equipment such as BBU (BBU full name Building Baseband Unit, Indoor baseband processing unit), RRU (RRU stands for Remote Radio Unit, remote radio frequency module) and other indoor distribution systems, but the transformation involved requires a lot of manpower and material resources. In addition, due to controversial issues such as the limitations of cable laying and the inability to enter the venues that have been handed ...
