To ensure that Access Points (APs) are installed in the exact locations specified in the design, it's essential to use visual aids and physical markers.Cameras can capture images of the intended installation sites, and marking tools can be used to indicate precise mounting locations on-site.This approach minimizes errors during installation and ensures adherence to the design plan.
The CWDP-305 Official Study and Reference Guide highlights the use of such tools:
"Use cameras and marking tools to document and indicate AP placement, ensuring accurate installation according to the design." Reference: CWDP-305 Official Study and Reference Guide, Chapter on Post-Design ValidationandTroubleshooting

When establishing a long-distance wireless bridge, such as one spanning 13 kilometers, it's crucial to consider the Fresnel Zone, which is the elliptical area around the line-of-sight path between two antennas. Obstructions within this zone can cause signal degradation due to diffraction.
One significant factor affecting the Fresnel Zone over long distances is the Earth's curvature, commonly referred to as the Earth bulge. As the distance between the two points increases, the Earth's surface curves away, potentially intruding into the Fresnel Zone and obstructing the signal path. Therefore, engineers must calculate the Earth's bulge and ensure that antenna heights are sufficient to maintain a clear Fresnel Zone.
While Free Space Path Loss (FSPL), antenna gain, and receiver sensitivity are essential parameters in link budget calculations, they do not directly address the physical clearance required in the Fresnel Zone.
