Product Introduction
With a maximum transmission range of up to 48 kilometers, the VDC-48 ensures stable, high-quality connectivity even in complex environments. It integrates a suite of intelligent features including real-time interference detection, automatic retransmission, adaptive frequency selection (with 12 selectable frequency points), and adaptive bitrate control, which dynamically adjust to changing signal conditions.
These capabilities significantly improve anti-interference performance and multipath resistance, maintaining high reliability and transmission stability in challenging field operations.
Product features
The system also incorporates automatic power control, optimizing output based on transmission conditions to reduce energy consumption and mitigate RF noise in shared spectrum environments. With a working temperature range of -40°C to +75°C, the VDC-48 is built to perform in extreme climates, making it suitable for both harsh industrial deployments and mobile outdoor missions.
Compact yet powerful, the VDC-48 is compatible with a range of airborne or ground-based platforms and supports various network configurations through its flexible interface design. Whether deployed for live video backhaul, telemetry exchange, or command/control data streams, it provides a robust, bi-directional communication backbone that ensures mission success across multiple domains.
