Icon Meaning
Depending on
your AirCard
configuration,
you may have
two signal
strength
indicators. If you
have two, the
indicator on the
right shows the
WiFi signal
strength (the
hotspot with the
strongest signal).
Signal strength and service status. The
number of bars beside the antenna
increases as signal strength increases, to a
maximum of five bars. The ToolTip that
displays when you position the mouse
pointer over this indicator, shows the
numeric value of the RSSI (Received
Signal Strength Indication in dBm).
Blank bars in the signal strength indicator
mean that you are outside of the coverage
area or have insufficient signal strength to
maintain a GSM data connection.
A red thermometer icon indicates
overheating. In the unlikely event that this
occurs, the AirCard suspends data
transmission until the temperature drops,
then normal operation is resumed. (This
usually takes no more than 10 seconds.)
A red flashing antenna icon indicates an
antenna problem. If this occurs, try
reorienting the antenna and ensure that
there is nothing on or near the antenna that
could be blocking the signal.
Depending on
your AirCard
configuration,
you may not have
this indicator.
Coverage. The icon shows the best
service available where the:
• gprs icon—indicates that GPRS is
the fastest service available
• edge icon—indicates that EDGE is
the fastest service available
• 3G—indicates that UMTS is the
fastest service available
• HS—indicates that HSDPA is the
fastest service available.
When only the letters are displayed, you
are within coverage but have not yet
acquired the service.
When the indicator has an outline, you
have acquired service and are able to
establish a connection.
When the indicator is filled, you have a
connection on the service.
