Огляд продукту

The COFDM Transmitter Wireless Video Modulator is a professional-grade digital video and audio transmission solution designed to meet the demands of modern broadcasting, UAV reconnaissance, моніторинг безпеки, and mobile communications. By adopting advanced COFDM (Кодовано мультиплексування з ортогональним частотним поділом) модуляція і MPEG-2/H.264 video compression, this system delivers стабільний, в реальному часі, і високоякісну передачу відео over long distances — even in поза межами прямої видимості (NLOS) environments or under complex interference conditions.

Unlike conventional analog wireless systems or narrowband digital transmitters, this COFDM wireless solution maintains consistent performance in environments affected by multipath reflections, urban obstacles, або високошвидкісний рух. Він підтримує обидва HDMI і HD-SDI video inputs, making it versatile enough for professional cameras, Корисне навантаження БПЛА, or mobile broadcast setups. On the receiving side, multiple output interfaces such as HDMI, USB, and Wi-Fi ensure compatibility with Android/iOS devices, recording equipment, or live monitoring stations.

The system is available in ultra-compact PCB module versions for OEM integration into UAVs, handheld devices, or embedded platforms. With transmitter modules weighing less than 20g and receiver modules under 25g, the COFDM transmitter is ideally suited for applications where weight and space are critical factors. Despite its size, це забезпечує >2 km transmission distance (standard ISM 900 Діапазон МГц), latency as low as 30 РС, and outstanding resistance to interference.

This product line offers a full spectrum of deployment options — from lightweight UAV micro-modules to rugged housings for ground-based broadcasting. Whether for aerial video downlink, негласне спостереження, mobile news gathering, or wireless event broadcasting, the COFDM Wireless Video Modulator provides the ideal balance of performance, надійність, and mobility.
