HD1080PTA Soldier Duplex Voice HD Video System

Overview

The HD1080PTA Soldier Duplex Voice HD Video System is a broadcast-grade, soldier-borne transmission platform that combines full HD 1080P video relay with full-duplex voice intercom and bidirectional data communication in a single integrated package. Built around COFDM modulation with configurable 2/2.5/4/8MHz channel bandwidth, it delivers stable, high-quality video transmission under non-line-of-sight (NLOS) conditions and during high-speed motion.

Unlike conventional one-way video transmitters, the HD1080PTA adds simultaneous two-way voice and RS232/RS485 data channels, enabling field operators to communicate and share telemetry while transmitting live HD footage. The transmitter mounts to a standard backpack frame for all-day carry and delivers 1-5W of adjustable RF output across a wide 300-4400 MHz frequency range, making it suitable for diverse operational theaters.

Key Features

• Full-duplex digital voice intercom for simultaneous two-way communication during video transmission
• Dual data channels -- RS232 and RS485 at 115200 bps for telemetry and peripheral integration
• 1-5W adjustable COFDM transmit power across 300-4400 MHz with LCD control
• SDI + HDMI + CVBS video inputs for compatibility with virtually any camera source
• 128-bit dynamic AES encryption for secure tactical links
• Spatial diversity dual-antenna receiver for robust multipath rejection
• Standard backpack frame with SONY V-lock battery plate for field-swappable power
• 300 ms system latency for near-real-time command and control

Technical Highlights

The HD1080PTA employs COFDM modulation to split the video stream across hundreds of orthogonal subcarriers, delivering exceptional resistance to multipath fading and frequency-selective interference. Its full-duplex FDD architecture keeps the voice and data channels independent from the video link, enabling uninterrupted communication even during active transmission.

The system includes a 1U 19-inch rack-mount receiver with built-in LCD display, signal strength indicator, and dual-antenna spatial diversity. The receiver's cavity filtering technology further enhances selectivity in congested RF environments. With sensitivity of -99dBm at 4MHz bandwidth, the link maintains lock at extended ranges through urban, forested, and mountainous terrain.

Applications

The HD1080PTA is designed for soldier-to-vehicle and soldier-to-command-center operations where high mobility and two-way communication are essential. It is deployed in broadcast field production, public security operations, firefighting command, civil air defense, maritime patrol, customs border patrol, and military reconnaissance.

At higher power levels, the system supports large-area mobile coverage for major events, search-and-rescue missions, and emergency response. The overall transmission chain typically runs from the soldier-borne transmitter to a communication vehicle, then via relay to a local or remote command center over IP networks.

Why Choose This System

The HD1080PTA is the only soldier-grade system in its class that integrates full-duplex voice, bidirectional data, and broadcast-quality HD video in a single backpack-mounted unit. Its FDD voice channel means operators never have to choose between talking and transmitting -- a critical advantage for teams that need to coordinate in real time while maintaining visual awareness of the incident scene.
