Controller Based WLANs

How do I perform a site survey using software?

Aruba Employee

Product and Software: This article applies to all Aruba controllers and ArubaOS versions.

 

The typical wireless passive survey methodology uses professional survey software utilities from companies such as AirMagnet and Ekahau to measure existing signal propagation within the designated coverage areas. The many varieties of building structures, designs, and materials can impact the RF signal. So, the survey tool effectively captures the "actual" RF signals that originate from the access points (APs). Aruba recommends that you perform passive surveys to confirm coverage after each facility is complete.

 

This example uses Ekahau Site Survey Pro:

To perform a passive survey:

 

1) Obtain the current electronic floor plan of the facility.

2) Use the site survey software application, walk through the coverage area, and sample the RF path every few feet.

3) Analyze the data to produce heat maps of the existing coverage and to look for sources of external interference.

4) Ensure that coverage exceeds the minimum targeted needs for the facility.

5) Ask an experienced WLAN engineer to assess the passive survey data to validate the choice of AP locations.
