1. PRODUCT OVERVIEW
This document provides the information re-
quired for the installation, operation and
verification of the
DATARADIO G3.
1.1 Intended Audience
This document is designed for use by engi-
neering design, installation, and mainte-
nance personnel.
1.2 General Description
G3 is a mobile radiomodem aimed at the
public safety and public utility markets to
meet demand for high speed and high
throughput. It integrates all the necessary
hardware for data-only vehicular installations
up to but not including the laptop PC and its
application software.
Example of applications are:
1. Database inquiry systems.
Small number of brief messages, (usu-
ally from the mobile station) with fairly
long responses.
2. Computer-aided dispatch (CAD).
Large number of messages, (usually
from the base station) with very brief re-
sponses.
3. Automatic Vehicle Location (AVL).
Using built-in GPS receiver, determines
position, speed and direction of fleet
members.
G3
is made-up of:
• A main transceiver
• An auxiliary receiver for Parallel Decode
(PD)
• A 30-Watt power amplifier A G3
Control Unit (GCU) with DSP driven
modem
• An integrated OEM GPS receiver.
1.2.1 Features
• One-piece integrated design in a rugged
die-cast aluminum chassis.
• Parallel Decode (PD) technology featur-
ing dual receivers for added decode sen-
sitivity in multi-path and fading envi-
ronments.
• Sophisticated DSP-based modem design
provides added system performance,
fewer retries and more effective
throughput.
• Automatic channel changing for im-
proved roaming capabilities.
• Built–in, up to 16-channel flash –
EEPROM programmable synthesized
radio transceiver with automatic channel
selection.
• Model with on-air 128kbps data speed
using RC16FSK modulation type.
• 4 available user ports using standard
USB, RS-232 or RJ45 (Ethernet)
interfaces via built-in multiplexer.
• Half-duplex operation.
• Out-of-band signaling enables transmis-
sion of GPS reports with no effect on
system performance.
1.2.2 Configuration
G3 is factory configured based on each cus-
tomer network system requirements, usually
