What is the difference between GPS, Wi-Fi and cell-site location?¶

GPS calculates position from satellites, Wi-Fi positioning compares nearby access points with a location database, and cell-site evidence derives from mobile-network connections.

Precision depends on method and environment¶

GPS can be precise outdoors but degrades indoors or among obstructions. Wi-Fi can work indoors but relies on accurate, current access-point mapping. Cell sites usually indicate broader areas affected by network conditions.

Combined estimates need source detail¶

Operating systems often blend satellite, Wi-Fi, cellular and sensors into one estimate. Preserve method, accuracy, timestamp and motion context rather than treating decimal precision as guaranteed accuracy.
