Location and tracking technologies: Understanding the technology

In principle, the use of a Wi-Fi signal for location and tracking is simple. There's no need for the approach used in RADAR, generating and bouncing a signal off of the object to be located or tracked, because Wi-Fi-equipped devices are usually transmitting data, and with that unique information identifying a given station. Once a given environment is installed with sensors or access points, as required to meet the specifications of a given solution, and any calibration required to tell the infrastructure what to expect when signals are sent from a known location - a form of RF fingerprinting, if you will - you're good to go.
