Google Maps impedes GPS functionality in Android devices
In a groundbreaking development, Google Maps is now using Bluetooth beacon technology to revolutionise navigation in areas with poor GPS signal, such as tunnels and parking garages. This innovative feature, known as "Bluetooth Beacons for Tunnels," is currently exclusive to Android devices due to iOS restrictions on background Bluetooth usage.
The technology works by transmitting location data over short distances, allowing for independent location tracking without the need for a satellite signal. This means that even when GPS signals are lost, Google Maps can connect to Bluetooth beacons installed in tunnels and other underground locations like parking garages and train stations, maintaining accurate location tracking.
To enable the Bluetooth beacon feature, Android users need to open the Google Maps app, go to Settings, then tap Navigation followed by Driving options, and switch on the Tunnel Bluetooth Beacon feature. You will need to grant the requested Bluetooth permissions for it to work properly.
The use of smartphones for navigation is becoming increasingly common due to their convenience and versatility. Unlike traditional navigation devices, navigation apps like Google Maps can do much more. In addition to providing directions, they can offer real-time traffic updates, local business information, and even public transit options.
For better overall navigation accuracy, especially on foot, you can recalibrate your phone’s compass by moving the device in a figure-eight motion. Also, keeping Wi-Fi and mobile data on (even without an active connection) and disabling battery saver mode helps Google Maps maintain optimal performance.
The Bluetooth beacon technology for navigation is little known but is currently being used by Google for navigation services. The magazine "Computer Bild" reported on this technology in its current issue (18/2025).
As we move forward, it remains to be seen whether this technology will be extended to iOS devices. For now, Android users can enjoy the benefits of seamless navigation in tunnels, making their journeys smoother and more reliable.
- The Bluetooth beacon technology, utilized in Google Maps, also supports the location tracking of various gadgets, such as smartphones, within tunnels and other underground areas, when GPS signals are weak.
- As more people rely on smartphones for navigation, the integration of innovative technology like Bluetooth beacons can enhance user experience, offering features like real-time traffic updates and public transit options, making the journey more efficient.
