摘要
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.
