7. Radio Path Planning Although the wireless bridge uses IEEE 802 11a radio technology which is capable of reducing the effect of multipath signals due to obstructions the wireless bridge link requires a radio line of sight between the two antennas for optimum performance The concept of radio line of sight involves the area along a radio link path through which the bulk of the radio signal power travels 3 1 Bridge Link Planning 3 2 This area is known as the first Fresnel Zone of the radio link For a radio link not to be affected by obstacles along its path no object including the ground must intrude within 60 of the first Fresnel Zone The following figure illustrates the concept of a good radio line of sight Visual Line of Sight Radio Line of Sight If there are obstacles in the radio path there may still be a radio link but the quality and strength of the signal will be affected Calculating the maximum clearance from objects on a path is important as it directly affects the decision on antenna placement and height It is especially critical for long distance links where the radio signal could easily be lost When planning the radio path for a wireless bridge link consider these factors e Avoid any partial line of sight between the antennas e Becautious of trees or other foliage that may be near the path or may grow and obstruct the path Radio Path Planning e Be sure there is enough clear
