One-Way COFDM Wireless Video Transmitter and Network Port Transmission Module

Plik One-Way COFDM Wireless Video Transmitter is a high-performance transmission solution designed for professional applications requiring stable, dalekiego zasięgu, and high-quality wireless data and video delivery. This module combines a Nadajnik i odbiornik COFDM system, wspierający one-way network port wireless transparent transmission, making it ideal for CCTV, monitoring przemysłowy, live video streaming, and other applications where reliable data transfer is critical.

The module operates in a one-way transmission mode, meaning that it sends data from the transmitter to the receiver without requiring a return signal or feedback from the receiver. This type of system is efficient, cost-effective, and ideal for scenarios where two-way communication is not necessary, such as security camera deployments, point-to-point video links, or fixed wireless networks. The transmitter converts the incoming network data into a COFDM-modulated RF signal and sends it over the air, while the receiver captures and converts the signal back to network data for seamless integration into IP networks.

Kluczowe cechy i funkcjonalność

Technologia modulacji COFDM:
The transmitter uses Kodowane multipleksowanie z ortogonalnym podziałem częstotliwości (COFDM), which provides excellent resistance to multipath interference, zblakły, and environmental noise.
