Raven XE

If you want to connect remotely to your Raven XE using TCP/IP, the IP address
Caution:
given to your modem by your cellular provider cannot be a private or internal IP address
(such as a special private network) unless you are on the same network or inside that
network's firewall (such as with frame relay).
EV-DO
CDMA (Code Division Multiple Access) is the underlying digital radio network
technology used by many cellular providers across the globe and is prevalent in
North America. To provide backward compatibility and seamless connections in
a wider range of locations, Sierra Wireless EV-DO products your Raven XE will
fall back to 1x when EV-DO is not available.
Sierra Wireless is certified with your cellular provider, a prominent North
American 1x and EV-DO carrier.
EV-DO revision A is an enhancement on the original revision 0 adding expanded
upload capabilities and a more robust connection overall. In addition to increasing
the downlink speed, revision A also increases the uplink speed. In addition, it is
backwards compatible and automatically connects with existing and broadly
deployed EV-DO Rev. 0 and 1x networks ensuring reliable and pervasive
connectivity.
Security
1x data transmissions are highly secure. Originally developed based upon the
"spread spectrum" pioneered by the US Department of Defense, security in
CDMA technologies is obtained by spreading the digital information contained in
a particular signal of interest over multiple coded paths, over a much greater
bandwidth than the original signal.
Connection methods
You can connect the Raven XE to a USB or a Ethernet (RJ45) on a computer.
When connected to a USB or Ethernet port, the Raven XE behaves like a network
card.
USB
The Raven XE is equipped with a USB port which increases the methods by
which you can send and receive data. The USB port can be set to work as either
a virtual Ethernet port or a virtual serial port. A driver installation is required to
use the USB port in either mode.
It is recommended that you use a USB 2.0 cable with your Raven XE and connect
directly to your computer for best throughput.
