Note: Optimal signal strength is
obtained when the antenna is
perpendicular to the AirCard. The Connection Status area uses these icons:
Table 4-1: Connection Status Area Icons
Icon Meaning
The Signal Strength indicator uses bars to
show the intensity of the radio signal. The
number of bars increases as signal
strength increases to a maximum of five
bars.
When the bars are dimmed and the
antenna icon is crossed out, no connection
is possible for one of these reasons:
• No antenna is attached
• You are outside the CDMA network
coverage area
• The signal strength is too weak
• A network or account problem is
preventing the AirCard 555 from
obtaining service
The 1x indicator shows whether 1xRTT is
available in this area.
Where 1xRTT packet service is available,
you can make high speed Express Network
data connections, if your billing plan allows
for it. (Depending on your billing plan, there
may be a surcharge for 1xRTT data
connections.)
Note that this indicator does not distinguish
between voice service and packet service.
If you are in an area where 1xRTT voice
service is available, this indicator may be
on although packet service is not available.
