SkyLift is an experimental Wi-Fi/BT geolocation spoofing device that uses the ESP8266 or ESP32 boards to broadcast Wi-Fi beacon frames or BT advertisements that emulate the wireless infrastructure from a remote/target location. The above example shows a successful georelocation to Peter Thiel's vacation house in Hawaii from the DataPools project (2018).

Mobile devices (i.e. iOS and Android) rely on this information for core geolocation services when space-based GPS signals are weak, which often occurs in urban areas or basement-like spaces.

The project has been most successful when using multiple SkyLift devices in outdoor settings positioned similar to the real (target) routers, overwhelming the existing Wi-Fi infrastructure and confusing most mobile devices. It also worked well in crowded indoor environments where bodies (which are 2/3 water) absorb Wi-Fi energy because 2.4GHz is the resonant frequency of water molecules.

However, it's still unclear what the best settings are for the Wi-Fi packet structure, what other factors affect ability to override core geolocation services, and if mobile operating systems have integrated anti-spoofing technologies. Most likely success with this code will be limited in general settings, though the low cost of prototyping hardware and potentially significant results make it a worthwhile project to explore further.
