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.

Predictive modeling software can predict the ideal access point location 100% of the time,
whereas the results from manual surveying are less reliable.

Predictive modeling software makes it simple to assess multiple different AP locations and then
adjust and display the AP’s expected coverage pattern in almost real-time.

Predictive modeling software provides more reliable data than manual surveys when fine-tuning
and validating access point placement after the installation.

The exact impact of interference sources from external networks can be more accurately
measured when using predictive modeling software than with manual surveys.

It takes less time to create an initial site survey for a large facility when using predictive
modeling software than when performing a manual survey.

The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime
consideration.

The omni-directional antennas of the access points should be oriented parallel to the floor to
maximize the coverage pattern across as many floors as possible.

The channel reuse pattern should be three dimensional with the RF cell extending coverage of
each access point to other floors.

The Fresnel Zone is completely blocked between floors so each floor is considered a separate
site survey.

VoIP phones and 802.11 access points should not be powered by the same edge switch due to
distortion.

he edge Ethernet switches should support Ether-channel to get the best results out of the
network.

If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal
locations for 802.11 APs.

The power budget in the edge switches must be carefully planned and monitored based on the
number of supported PoE devices.
