Abstract: A system and a method for obfuscating a mobile device's location are provided. For privacy or security reasons, the user of a mobile device may desire to prevent the mobile device from reporting the mobile device's true location. To prevent a mobile device from determining its location accurately, an RF enclosure encapsulates the mobile device and prevents the mobile device from receiving RF signals from sources outside of the enclosure. Within the enclosure, antenna modules broadcast RF signals, such as cellular-network signals, Wi-Fi signals, Bluetooth signals, or GPS signals, that contain information associated with a user-selected target location. The mobile device receives the RF signals from the antenna modules and determines that it is located at the target location rather than the true location.
