An RFID site survey is a physical survey of the premises where the use of RFID equipment is will be installed and implemented.
The survey identifies optimal locations for the physical installation of RFID readers and antennae. When considering the use of RFID equipment, it can be difficult to predict the propagation of radio waves while detecting the presence of interfering signals without conducting a site survey.
Regardless of the antennae technology, radio waves do not travel the same distance in all directions. Walls, doors, infrastructure (metal, shafts, etc.), people, and other obstacles offer varying degrees of attenuation, which cause the radio frequency (RF) radiation pattern to be irregular and somewhat unpredictable. As a result, an RFID site survey should be performed to understand fully the behavior of radio waves within a facility.
The goal of an RFID site survey is to gather enough information to determine both the quantity and placement of RFID portals (readers and antennae) that will provide optimal coverage, as well as to identify any necessary power and network connectivity points. During the site survey, decisions can be made regarding mounting of fixed readers as well as optimum placement of antennae at controlled capture points.
The need and complexity of an RFID site survey will vary depending on the size of the facility and the work that is to be accomplished. When the necessary data is gathered from the site survey, the RFID equipment is tested under similar conditions. A detailed report is generated and submitted for approval prior to ordering and installing the hardware.
