Power up and the
connection to the
Internet
After power is applied, the Hughes 9450 IDU and Hughes
Tracking Antenna will begin their start-up sequence. The
tracking antenna will begin its search for the BGAN
satellite and the antenna motors may be heard during this
time. Note that the tracking antenna must have line of sight
to the BGAN satellite. Once the antenna has locked onto
the BGAN satellite, it will continue to make minor
adjustments to acquire optimum signal strength. The
antenna may be heard ‘twitching’ during this time.
Eventually the antenna will sit at an optimum position
while the vehicle is stationary.
Once the vehicle starts moving, the Hughes Tracking
Antenna will automatically track the satellite signal and
keep the antenna pointed towards the satellite. During
short outages (e.g. while driving under a bridge, etc.) the
antenna will remain in the same position and will pick up
the satellite signal immediately. For longer outages the
antenna may need to repeat the search pattern to reacquire
the satellite signal.
Circuit switched and packet switched connections will
typically recover from signal outages of less than 60
seconds. User intervention
will
be required to reactivate
circuit switched connections for outages longer than 60
seconds and
may
be required for packet switched
connections depending upon the actual length of outage.
Packet switched connections like FTP are more robust
than circuit switched connections in the network.
Connecting the
terminal to the
computer
You can connect your computer to the 9450 IDU with one
or more of the following interfaces
•
Ethernet
•
WLAN (not 9450E or 9450L)
