Summary of RF Behavior

In your own words, summarize what you have learned concerning RF behavior from your calculations, readings, and research.

RF behavior is not clear cut as most people think. The concept of a singular signal being produced and connecting to the receiver in a straight line is incorrect. The signal can bounce off of any object or other signal within its path or near. There may be many signals that can reach the receiver at different times, with this process called multipath. There are different behaviors that the signal can take on during the transmission process. Those behaviors could be: absorption, diffraction, scattering, refraction and/or reflection.

Absorption occurs where the signal is absorbed into the material that it’s around. An example of that type of material is concrete or wood. Diffraction occurs when an object with rough edges is in the path of the signal and the signal has to bend to go by. Scattering occurs when small objects or object with rough surfaces are in the path of the signal. Objects such as rocks, foliage, or sand. Reflection occurs when large and smooth objects are in the path of the signal and the signal bounces off the object. This is the exact opposite of absorption.. Objects such as walls or buildings. Refraction occurs when a signal travels thru different atmospheric condition. The signal may start out in sunshine and pass thru cold damp air which causes the signal to bend instead of traveling in a straight line. The bending of the signal is called...
