Raven X - Telus EV-DO Airlink Cellular Modem
1
Introduction
The Raven X - Telus Airlink Cellular Modem is a full-duplex
cellular modem that communicates with a base station PC via the
Evolution Data Optimized (EV-DO) network, with fallback to 1X
Code Division Multiple Access (CDMA) and Public Switched
Telephone Network (PSTN). The Raven X - Telus modem is for
use on the Telus network only.
The Raven X - Telus 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.
