GPS & AGPS
GPS & AGPS Your mobile device can use Global Positioning System (GPS) signals for location-based
applications. GPS uses satellites controlled by the U.S. government that are subject to
changes implemented in accordance with the Department of Defense policy and the
Federal Radio Navigation Plan. These changes may affect the performance of location
technology on your mobile device.
Your mobile device can also use Assisted Global Positioning System (AGPS), which
obtains information from the cellular network to improve GPS performance. AGPS uses
your wireless service provider's network and therefore airtime, data charges, and/or
additional charges may apply in accordance with your service plan. Contact your wireless
service provider for details.
Your Location
Location-based information includes information that can be used to determine the
approximate location of a mobile device. Mobile phones which are connected to a
wireless network transmit location-based information. Devices enabled with GPS or
AGPS technology also transmit location-based information. Additionally, if you use
applications that require location-based information (e.g. driving directions), such
applications transmit location-based information. This location-based information may be
shared with third parties, including your wireless service provider, applications providers,
Motorola, and other third parties providing services.
Emergency Calls
When you make an emergency call, the cellular network may activate the AGPS technology
in your mobile device to tell the emergency responders your approximate location.
AGPS has limitations and might not work in your area. Therefore:
• Always tell the emergency responder your location to the best of your ability; and
• Remain on the phone for as long as the emergency responder instructs you.
Performance Tips
• Go outside and away from underground locations, covered vehicles, structures
with metal or concrete roofs, tall buildings, and foliage. Indoor performance might
improve if you move closer to windows, but some window sun shielding films can
block satellite signals.
