Limitations of AGPS
Sometimes adequate signals from multiple satellites are
unavailable, usually because your AGPS phone’s antenna
cannot establish a view of a wide area of open sky. In
these cases, the AGPS feature
will not work . Such
situations include, but are not limited to, the following:
• in underground locations
• inside of buildings, trains, or other covered vehicles
• under any other metal or concrete roof or structure
• between tall buildings or under dense tree cover
• near a powerful radio or television tower
• when your AGPS antenna is covered (for example, by
your hand or other object) or facing the ground
• when there are temperature extremes outside the
operating limits of the phone
Even where location information can be calculated in such
situations, it may take more time than usual, and your
location estimate may not be as accurate.
Even where adequate signals from multiple satellites are
available, your AGPS feature will provide only an
approximate location, often within 150 feet (45 meters) but
sometimes much farther from your actual location.
