Digital COFDM Video Wireless Transmitter , Hdmi Wireless Audio Transmitter Government Military Police


COFDM Video transmitter Anti-electromagnetic interference performance:

It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each subcarrier joint coding. In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few subcarriers will be interfered What’s more, these sub-channel can adopt ECC to correct error, to guarantee the transmission low error rate.


COFDM Video transmitter Anti-multipath fading:

It can confront signal waveform interference effectively; suitable for multi-path environment and fading channel high-speed data transmission. When the frequency selective fading appear in the channel because of multi-path transmission, only the sub-carrier, which fell over the band depression, and the information carried will be affected. Other sub-carriers will not be affected. Thus, the system total error rate performance will be much better.


COFDM Video Wireless Transmitter Specification

The C328 transmitter is a mini COFDM video transmitter from Wireless LinkAV,designed specifically for covert video installation applications. With proven LinkAV COFDM technology at its core, the small size and low power consumption of the C328 Transmitter make it the product of choice for covert video hides, or applications requiring long term battery power deployments,small unmanned aerial vehicles, and body-worn use. The C328 Transmitter employs low latency High Profile H.264 (MPEG-4 ) encoding for excellent image quality retention over the wireless link. Equipped with integral COFDM modulation, it is ideal for establishing rugged wireless video links in numerous environments, including mobile and urban. Offering several user-selectable modes that trade off image quality against range, it is very well suited to all mission types. Security is ensured with optional AES128/256 Encryption.C328 transmitter will transmit images in a non-line of sight environment up to 1km,depending on mode and frequency.
