Antenna Descriptions

The MicroCell has one antenna for cellular signals and another for GPS signals. If GPS signal
strength is too low, a port for connecting an optional GPS antenna extension is also available.
All three are described below:

Cellular Antenna

The cellular antenna is mounted inside the MicroCell enclosure and is for transceiving cellular
traffic with registered 3G devices. The maximum range of the AT&T 3G MicroCell™ is approximately
5000 square feet. Actual range will be limited by the density of obstructions.
GPS Antenna
The GPS (Global Positioning System) antenna is mounted inside the MicroCell enclosure and is
for receiving GPS signals. It cannot be adjusted, but has enough gain in most instances to detect
signals in any room with a window.
If the GPS link is unreliable (indicated by a flashing GPS status LED), try the following procedure:
• Move the MicroCell closer to a window.
• Recycle power on the MicroCell to restart authentication.
• You'll know if the effort was successful if the GPS status LED turns to steady green.
If this procedure fails, try installing the optional GPS antenna extension.

Then...
Traffic across the MicroCell has risen to a critical level.
• Check for unusually heavy data requests (video downloads are
likely suspects) and limit them, if possible.
• If the decline is chronic, consider upgrading service.
The device may not be registered (see Activate Your Account on
page 12 and follow the instructions on how to access your account
and register 3G devices).
The MicroCell may be serving a full load of calls.
The MicroCell can support up to four simultaneous calls.
