GPS Settings
GPS (Global Positioning System) is a system that uses
a series of geosynchronous satellites to provide
location data. GPS satellites transmit signals to
equipment on the ground. GPS receivers passively
receive satellite signals, but do not transmit. GPS works
wherever you have line-of-sight access to the GPS
satellites.
To configure the GPS settings:
1. From the Web management page, click the
Settings tab.
2. Select WAN > GPS Settings.
Note: To access GPS services, GPS receivers must be locked
onto the global positioning satellites to accurately
determine positions. Therefore, GPS services are
typically unavailable indoors due to indoor obstacles
and may return inaccurate position data. Moreover, the
device may not get a clear view of the satellites due to
weather conditions.
