In the long-distance transmission of wireless signals, the Fresnel Zone (Fresnel Zone) is an important concept.
Which of the following statements about the Fresnel zone is true
A. The wireless signal propagates in a straight line, but spreads out when it propagates, and the necessary clearance between the beams is called the Fresnel zone.
B. Any obstacle in the Fresnel zone may affect the communication of the network, it is best to give it clear, to ensure that 60% of the Fresnel zone is considered effective. Generally based on experience
C. The size of the Fresnel zone is a function of the length of the path, the longer the path, the wider the Fresnel zone.
D. The Fresnel zone is an elliptical area formed in the path of the line of sight. It varies with visibility distance and signal frequency, and the necessary Fresnel zone clearance is at the center of the path
