Introduction to Raven GPRS
4 Cingular GPRS Raven User Guide Version 2.01
If you need to contact the Raven, a device connected to the modem, or a host sys-
tem using the modem, you need to have a known IP (such as one which is static) or
domain name (an IP address which is converted by a DNS server into a word based
name).
Most ISPs (cellular included) use dynamic IP addresses rather than static IP
addresses. A dynamic IP address is suitable for many common Internet uses, such
as web browsing, looking up data on another computer system, or other client func-
tion (such as data only being sent out or only being received after an initial request).
If you have a dynamic IP address for your Raven, you can use a service (such as IP
Manager, covered later in this User Guide) to translate a dynamic IP address to a
fully qualified domain name so you can contact the Raven as if it had a static IP.
Common Uses for the Raven
The Raven’s rugged construction and cellular connection make it ideal for use in
remote and/or industrial locations. The Raven can be used for telemetry and for
more advanced communication to the device or devices behind it.
