Refraction In Radio Communication

REFRACTION IN WIRELESS COMMUNICATION

Refraction is bending of signals as it passes from one medium to another . Refraction causes degradation in signal strength and sometimes loss of communication in Point to Point links.

Loss of communication in P2P link occurs in long distance links when there in change in atmospheric refractive index which causes signals to divert from original path and communication does not take place.

Refraction also occurs when some non reflective medium comes as obstruction the signals refract into the medium but in this case when the signals comes out after penetrating the medium the signal follows the path parallel to original but with signal power degraded.

Not to be confused with reflection , In reflection the signal after striking the surface of another medium return back to the same medium and in refraction the signal penetrates into another medium with diversion from original path of signals.
