Gemini G3-UHF™
Mobile Data Modem for Private Networks
EXPERIENCE THE
ADVANTAGE
• Parallel Decode provides
added sensitivity in
multi-path environments
• HyperCode FEC maintains
connectivity and throughput
while in motion
• Integrated GPS for AVL and
for local mapping
MISSION CRITICAL CONNECTIVITY FOR MOBILE APPLICATIONS
The Gemini G3-UHF operates in the private licensed UHF spectrum. Designed
specifically for government, public safety agencies and public utilites, this model
integrates the necessary functionality for data-only vehicular installations.
The Gemini G3-UHF model combines dual IF filters for 12.5 and 25 kHz in a single
unit that offers seamless roaming across any combination of these channel bandwidths. If you plan to migrate to 12.5 kHz channel of whether your network is
optimized with both 12.5 and 25 kHz, the Gemini G3 product will ease your planning
by simply roaming automatically from one bandwidth to another, without manual
intervention.
• Dual IP filters support a mix
of channel bandwidth
Our patented Parallel-Decode technology, featuring dual receivers, and the use of
HyperCode forward error correction (FEC), allow for greatest sensitivity especially in
multi-path and fading environments. Equipped with a 12-channel GPS receiver, the
Gemini G3 can determine the position, speed and direction of the vehicle. This can
then be reported on-board the vehicle and/or to a remote dispatcher.
• On-line and off-line
diagnostics deliver real-time
performance statistics
Embedded web server provides browser access for status and configuration of
network parameters. Since the unit firmware and reconfigurations can be reprogrammed over-the-air, maintenance and upgrades are greatly facilitated.
• AES 128-bit data encryption
for data and network security
