1Introduction
The Raven CDMA Airlink Cellular Modem is a full-duplex, 1xRTT
cellular modem that communicates with a base station PC via Code
Division Multiple Access (CDMA) network and Public Switched
Telephone Network (PSTN). The Raven CDMA modem is for use on
Bell, Alliant, ManitobaTel, and SaskTel networks only.
The Raven CDMA is a rugged, intelligent wireless data platform
designed to enable real-time, two-way communications with remote
assets. The AirLink Embedded Operating System (ALEOS) is the
power inside the Raven. ALEOS has its own embedded TCP/IP stack
which enables transmission of serial data from non-IP devices. ALEOS
enables several functions including remote configuration and
diagnostics, packet assembly and disassembly (PAD) for UDP or TCP,
and telemetry protocol spoofing and conversion.
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 service such as IP Manager
(Section 5.4) to translate a dynamic IP address to a domain name,
so that the Raven can be contacted by name as if it had a static IP.
A Service Provider account can be set up for a Static or Dynamic IP
address; a Static IP is preferred.
