How does GPS Tracking Work On Smartphones?

What does Vismo do?

  • Smartphones and tablets have an internal GPS chip that allows them to accurately determine their position when outdoors. When indoors, other methods such as AGPS, Wi-Fi Access Points and Cell Tower triangulation are used to provide good quality location estimates.
  • Locations are sent to the Vismo Secure Portal over the internet.
