RF [Radio Frequency] waves travel in a straight line - what is called LOS [Line-Of-Sight]. This means the user must be in a straight line from the antenna for optimum performance. In addition, obstacles such as other AP [Access Points], buildings, and other objects absorb radio waves. Users may often receive radio waves which are reflected from other objects called multi-path. Multi-path radio signals are generally not as strong or as reliable as direct LOS [Line-Of-Sight].
