Therefore, temporary access points or signal sources can be used to gather information on propagation in the environment. It is essential that the correct information on the environment is entered into the RF modeling tool, including location and RF characteristics of barriers like walls or large objects. Active surveys are used to troubleshoot wifi networks or to verify performance post-deployment.ĭuring a predictive survey, a model of the RF environment is created using simulation tools. This used to be the most common method of pre-deployment wifi survey.ĭuring an active survey, the wireless adapter is associated with one or several access points to measure round-trip time, throughput rates, packet loss, and retransmissions. 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. ĭuring a passive survey, a site survey application passively listens to WLAN traffic to detect active access points, measure signal strength and noise level. There are three main types of wireless site surveys: passive, active, and predictive.

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.

Wireless site survey can also mean the walk-testing, auditing, analysis or diagnosis of an existing wireless network, particularly one which is not providing the level of service required. This involves determining the minimum signal to noise ratio (SNR) needed to support performance requirements. Interviews with IT management and the end users of the wireless network are also important to determine the design parameters for the wireless network.Īs part of the wireless site survey, the effective range boundary is set, which defines the area over which signal levels needed support the intended application. This requires analysis of building floor plans, inspection of the facility, and use of site survey tools. The survey usually involves a site visit to test for RF interference, and to identify optimum installation locations for access points.

Planning and designing a wireless networkĪ wireless site survey, sometimes called an RF (Radio Frequency) site survey or wireless survey, is the process of planning and designing a wireless network, to provide a wireless solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and quality of service (QoS).
