Understanding GPS Signal Strength and
Optimizing Wherifone Performance
The ability of the GPS satellite signal to get to the Wherifone will vary
depending on the environment in which the device is located. The
optimum condition to obtain accurate GPS performance is when there
is no obstruction between the open sky and your device. The signal
strength may be affected adversely in certain conditions such as under
metal or concrete structures, in the middle of an office building, or near
a powerful radio or other electronic devices. Also, try to minimize items
that could potentially cover the front side of the Wherifone. Hang the
device on the outer side of a child’s backpack using the lanyard,
carabiner, or belt clip case. If your child places the device inside their
shirt, pants, or backpack pocket, place it with the front side of the
device facing outward. When you are in the car, position the device
facing up and towards a window to get the best access to the sky. The
device will not work in an area where there is no mobile phone
coverage.
