ZKMANET1303R 20-30km Transmission COFDM HD Video Wireless Communication Receiver
ZKMANET1303R 20-30km Transmission COFDM HD Video Wireless Communication Receiver
The ZKManet1303R is a mini COFDM wireless receiver with dual antenna diversity reception. This system can transmit HDMI/AV videos with low-latency. It can work under all environments including high-speed mobile (NLOS), with a durable, compact and lightweight housing.
The system utilizes omnidirectional antennas, allowing for the rapid establishment of wireless transmission links. Both the capture and receiving ends can be moved freely without directional restrictions, making the system simple, reliable, and flexible in application. In complex electromagnetic environments, it demonstrates excellent anti-interference capabilities against frequency-selective fading or narrowband interference, as well as superior performance in mitigating interference between signal waveforms. Through joint coding of various subcarriers, it possesses strong resistance to fading.
