GPS range :
GPS (last place where your smartphone was next to yout wistiki) range is unlimited !
Bluetooth range :
Optimizing Wistiki's Bluetooth performances has therefore been the main focus of our Research & Development months, in order to make Wistiki one of the most reliable Bluetooth accessories in terms of range.
Bluetooth range can go up to 50 meters when there are no obstacles between Wistiki and Smartphone.
If your Smartphone and your Wistiki are separated by physical obstacles (walls, buildings..), the range will be lowered, since Bluetooth waves are abated by matter.
