Principles and applications of wireless transmission technology

Wireless transmission technology refers to the transmission of electrical energy from one end to the other through electromagnetic waves. This technology is not limited by transmission lines, making energy transmission more flexible, efficient and convenient. This paper describes the radio energy transmission from several aspects and analyzes their transmission theory. Finally, the characteristics of various transmission methods and possible application scenarios are comprehensively compared, and combined with three indicators of transmission efficiency, transmission power and transmission distance for comprehensive analysis.
