Pre-deployment surveys: At this stage, a site survey is necessary in order to verify that the network plan works well in a real-world environment. Placement of temporary access points (APs) and a quick survey of the resulting WLAN characteristics allow an engineer to fine-tune AP and antennae placement, determine the optimal number and types of APs and antennae, and avoid poor coverage zones.
Post-deployment surveys: Once a WLAN has been deployed, a complete verification site survey is necessary to ensure that the WLAN performance and coverage meet the design requirements. At this stage, the Wi-Fi equipment placement is finalized, and a site survey report should be generated so that the historical records can be accessed at any time in the future.
Regular, ongoing surveys: Maintaining high performance and coverage requires regular “check-up” surveys. New users, new equipment, site expansion, neighboring WLANs, and other factors can adversely affect your WLAN. It should be monitored on a regular basis.
