Explanation
GPS enables geofencing - the practice of defining a virtual geographic perimeter around a physical location such as a corporate building. With GPS-based contextual authentication, the authentication system can verify that a device is physically located within the defined corporate premises before granting access to enterprise resources. If a device is outside the geofenced area, access is denied regardless of valid credentials. Port security (A) controls access based on MAC addresses at physical switch ports, not geographic location. Rogue device detection (B) identifies unauthorized devices on the network but doesn't enforce location-based access control. Bluetooth (C) has very limited range (typically under 10 meters) and is not suitable for building-scale location verification.
