Introduction to Raven GPRS
When your Raven is powered on, it automatically searches for cellular service
using GPRS and establishes a PPP (Point to Point Protocol or “dial” up connection)
link to Cingular’s network. As soon as the Raven receives its IP, it’s ready to create
a TCP/IP network between your computer or device and Cingular’s network so you
can use Cingular to communicate on the Internet.
Using the Raven with a computer or network of computers behind a router using
NAT (Network Address Translation which allows several computers or devices use
a single IP address), you can access the Internet for web browsing, email, FTP, etc.

Note: Corporate network connections are unique for each configuration
and not covered as part of the standard installation.
Using GPRS to Communicate directly to your
Device
There are two types of addresses in TCP/IP, dynamic and static.
• Dynamic addresses are assigned on a “need to have” basis. Your Raven might
not always receive the same address each time it connects with Cingular.
• Static addresses are permanently assigned to a particular account and will
always be used whenever your Raven connects to Cingular. The address will
not be given to anyone else.
