Abstract: Provided are devices, computer-program products, and methods for calibration of a signal strength map for purposes of providing wireless positioning services through fingerprinting. Fingerprinting involves generating a map of the signal strengths in an area covered by a Wi-Fi network. In some implementations, a wireless probe request may be received. In these implementations, the wireless probe request may be associated with location information. In some implementations, the signal strength of the wireless probe request may be detected. In these implementations, the signal strength may indicate a signal characteristic between an origination and a destination for the wireless probe request. In some implementations, the wireless probe request may be responded to with a response message. In these implementations, the response message may include the signal strength of the wireless probe request. In these implementations, the response message and the location information may further facilitate generating an entry in a fingerprinting database.

Abstract: The present disclosure discloses a system and a method for displaying mobile trails for mobile client devices. Specifically, a network device obtains a plurality of performance measurements and a corresponding plurality of physical locations for a client device over a period of time. Then the network device generates a plurality of visual representations for the client device over the period of time, each visual representation representing a respective performance measurement and a respective physical location at a respective time during the period of time. Moreover, the network device can display, store, and/or transmit a map of a physical environment with the plurality of visual representations.
