![]() For system design purposes, one or more temporary access points are deployed to identify and qualify access point locations. However, the wireless adapter being used for a survey is not associated to any WLANs. There are three main types of wireless site surveys: passive, active, and predictive.ĭuring a passive survey, a site survey application passively listens to WLAN traffic to detect active access points, measure signal strength and noise level. ![]() In the past, however, these tasks required manual data recording and processing. After a survey, data analysis is performed and survey results are documented in site survey reports generated by the application.Īll these data collection, analysis, and visualization tasks are highly automated in modern software. The surveyor either marks the current position on the floor plan manually, by clicking on the floor plan, or uses a GPS receiver that automatically marks the current position if the survey is conducted outdoors. During a survey, a surveyor walks the facility with a portable computer that continuously records the data. Before a survey, a floor plan or site map is imported into a site survey application and calibrated to set scale. Wireless site surveys are typically conducted using computer software that collects and analyses WLAN metrics and/or RF spectrum characteristics.
