The RavenXTG digital cellular modem is manufactured by Sierra Wireless for
use on the AT&T General Packet Radio Service (GPRS) network. The modem
is accessed through the Internet using TCP/IP communications protocol using a
Static or Dynamic IP address.
• A Static IP address is permanently assigned to a particular account and
will always be used whenever the Raven connects to the Internet.
• A Dynamic IP address is assigned on a “need to have” basis. A dynamic
IP address is used with a DDNS service (Section 5) to translate a dynamic
IP address to a domain name, so that the Raven can be contacted as if it
had a static IP.
An AT&T GPRS account can be setup for a Static or Dynamic IP address. A
data account with the I2gold APN as described in Section 2.1 will have a Static
IP address.
2. Establish Cellular Service
2.1 RavenXTG Cellular Coverage/Service Requirements
What you need:
AT&T GPRS coverage at the datalogger site (for a coverage map refer to:
http://wireless.att.com/coverageviewer
).
GPRS account established with AT&T.
To setup an account with AT&T:
Call (1-800-331-0500) and ask for an “unrestricted data account for a GPRS
modem”. After the account has been setup, mobile termination will need to be
configured onto the account, which is done by adding the “I2gold APN” to the
account. Mobile termination makes the modem accessible through the Internet.
The APN name must be programmed into the modem as described in Section
5.1. Contact AT&T for additional APN information.
