A 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).
It is a comprehensive assessment of your wireless frequency to include issues such as channel interference, digital dead zones, and other obstructions to service.
The goal of the technicians that perform a WiFi site survey is to reconcile the initial WiFi engineering data with any changes that have occurred in the interim, to include installation of additional systems or new construction that may be affecting the signal.
