Wireless communication is a communication system that uses electromagnetic waves or air energy to exchange information about the characteristics of signals propagating in free space. The wireless communication system is limited and is susceptible to other electromagnetic waves and environmental conditions.
Carrier communication is a communication technology for transmitting messages by using high-frequency oscillation signals, and the basic principle is that an information signal is superimposed with an alternating current signal (called a carrier wave) with a fixed frequency, so that the frequency of the information signal is expanded into the range of the carrier frequency, and then the information signal is propagated through a transmission medium, and a receiving end obtains an original information signal through demodulation. Carrier communication is also susceptible to electromagnetic waves and its own frequency, and the distance of energy transmission of the communication is limited, if long-distance transmission is required, the medium of the signal needs to be enhanced independently.
