Abstract

The invention discloses a broadband carrier relay, a message transmission method and a message transmission device. The message transmission method comprises the steps of receiving a first message, wherein the first message is a broadband power line carrier message or a wireless message; converting the first message into a second message, wherein the second message is the broadband power line carrier message or the wireless message; determining a sending manner corresponding to the second message; and sending the second message in the corresponding sending manner. According to the relay, the method and the device provided by the invention, the technical problem that in related technologies, the problem of instability of a carrier signal link cannot be effectively solved in an area with large signal attenuation is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a broadband carrier repeater and a message transmission method and device. Background technique [0002] Power line carrier (PLC) technology has developed from narrowband power line carrier to broadband power line carrier. At present, the domestic mainstream still adopts narrowband power line carrier technology. Compared with domestic mainstream narrowband power line carrier, broadband power line carrier has great advantages: [0003] a. Broadband power line carrier adopts OFDM technology. The subcarriers support BPSK, QPSK, 8QAM, 16QAM, 64QAM and other modulation methods and functions such as FEC and CRC. Robust frame structure; [0004] b. Broadband power line carrier can realize stable and reliable two-way and real-time transmission of huge data. Even if a communication fails, it can be resent quickly to ensure data reliability; [0005] c. Broadband power line carrier can ...
