1. PRODUCT OVERVIEW
This document provides the information required for the installation, operation, and verification of the
Dataradio® GeminiG3™ wireless radiomodem.
1.1 Intended Audience
This document is designed for use by engineering design, installation, and maintenance personnel.
1.2 General Description
GeminiG3 – 700MHz 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, (usually 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 responses.
3. Automatic Vehicle Location (AVL).
Using built-in GPS receiver1, determines position, speed and direction of fleet members.
The GeminiG3 radiomodem is made-up of:
• A main transceiver
• An auxiliary receiver for Parallel Decode™
• A 10 to 25-Watt adjustable power amplifier
• A Gemini Processor/Modem board with DSP modem
• An integrated OEM 12-channel GPS receiver. 1
