With a spectrum analyzer, identify the type, amplitude, and location of RF interference sources, if any are present.

Evaluate the building materials at ABC’s facility and confirm that the floor plan documents are consistent with the actual building.

Test several antenna types connected to the intended APs for use in the eventual deployment.

Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers.

Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls.

Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.

The Fade Margin of a long-distance radio link should be equivalent to the receiver’s antenna gain.

A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnel zone is clear of obstructions.

The Fade Margin is a measurement of signal loss through free space, and is a function of frequency and distance.
