The invention discloses an indoor communication system based on a coaxial cable, the indoor communication system comprises a coaxial cable modulation and demodulation device and user equipment, and the coaxial cable modulation and demodulation device is in communication connection with the user equipment; the coaxial cable modulation and demodulation device is arranged in the wall body and is connected with a home-entry coaxial cable; the home-entry coaxial cable is used for supplying power to the coaxial cable modulation and demodulation device and providing a first radio frequency signal forthe coaxial cable modulation and demodulation device. The invention innovatively provides the indoor communication system with the coaxial cable modulation and demodulation device placed in the wallbody, so the problem of large occupied space of an existing indoor communication system can be solved, and the risk of electric shock of a user can be greatly reduced; moreover, the modulation and demodulation device is innovatively powered through a coaxial cable network, so that the problems of electric shock danger and accidental power failure possibly caused by an external power supply of equipment are effectively avoided. Therefore, the method has the outstanding advantages of high safety, high reliability and the like.
Description
technical field [0001] The present invention relates to the technical field of communication, and more specifically, the present invention is an indoor communication system based on coaxial cables. Background technique [0002] With the development of science and technology and the improvement of people's living standards, radio and television and broadband networks have become inseparable from people's lives, and with the emergence of new services such as ultra-high-definition video, AR / VR, and self-media live broadcast, people's demand for networks Higher and higher. Cable broadcasting and television systems generally transmit video and audio programs to the outside world through coaxial cables. At present, coaxial cable network broadband access systems mainly use HFC (Hybrid Fiber-Coaxial, hybrid fiber-coaxial network) network system, which uses optical fibers as the backbone network, Coax is a high-bandwidth network for branch networks. [0003] The equipment used in t...
