WLAN deployments because they provide the most details upon which to base a design.
There are two main methods used in active surveys:
Basic Service Set Identifier (BSSID) Method: This method locks a client into an AP's radio MAC
address and prevents the client from roaming.
address and prevents the client from roaming.

Service Set Identifier (SSID) Method: This is more commonly used for post−deployment scenarios
and used to survey multiple APs. It enables the survey client to associate to an SSID where the client
roams between multiple APs.

Predictive Surveys
Predictive surveys are performed with a software program. The program uses the information about the
coverage area to perform AP placements based on RF algorithms. These surveys are typically void of any type
of field measurements.
coverage area to perform AP placements based on RF algorithms. These surveys are typically void of any type
of field measurements.
The best times to incorporate a predictive survey include:
When the deployment environment has not yet been built.
•
In order to obtain a budgetary environment for WLAN−related hardware.
•
When roaming requirements are less stringent.
•
