Compatible communication equipment

Abstract

The invention discloses compatible communication equipment, comprising an analog front end, a base band communication unit, a wireless radio frequency module, a power line communication front end and a control unit. The analog front end is connected with the base band communication unit, the wireless radio frequency module and power line communication front end. The base band communication unit is used for transmitting a base band signal. The analog front end performs conversion to the signal between a numeric field and a simulation field. The control unit selects one of the power line communication front end or the wireless radio frequency module according to channel quality of signal transmission or simultaneously uses two modes to communicate, and receives or transmits the signal via a power line while using the power line communication front end to communicate, and receives or transmits the signal via a wireless channel while using the wireless radio frequency module to communicate. The compatible communication equipment of the invention could select appropriate channel to communicate according to different signal transmission conditions or different channel qualities, thereby improving communication reliability.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a compatible communication device. Background technique [0002] Power line communication (PLC) is a general term for all technologies that use power lines as communication channels. A system of PLC communication equipment transmits data by modulating communication signals over existing power lines, which are also used to supply power to homes, buildings, and other locations. This enables communicating devices to be networked without adding any new wires or cables. This feature is highly desirable in a wide variety of applications to take advantage of higher efficiencies across the network. Typically, PLC technology is used in utility meters, home area networks, home appliances, and lighting controls. [0003] Power lines have always been designed with unidirectional output power and the transmission environment is harsh during the communication signal propagation process....

AI Technical Summary

Problems solved by technology

However, for wireless communication technology, even if the physical distance is very close, there are still some communication equipment areas where wireless communication cannot be used normally. For example, there may be some obstacles in the basement of a building that block or weaken radio waves, making it difficult to guarantee the quality of wireless communication.
