HD Body Worn COFDM Video Transmitter UHF Digital Microwave Low Latency 150ms


Wireless 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.


Wireless 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.


Wireless COFDM Video Transmitter Specification:


The C321 transmitter is a body-worn COFDM video transmitter from wireless LinkAV, designed specifically for government video surveillance, Police law enforcement, border control, internal security, critical infrastructure protection, military command video transmission applications.


With the leading COFDM technology and H.264 encoder technology, enables viewers high definition images ideal for establishing rugged wireless video links in all environments including mobile and urban environments.


The integrate design makes the C321 transmitter ideal for applications requiring long term battery power deployments, it employs low latency High Profile H.264 encoding for excellent image quality retention over the wireless link. it is very well suited to all mission types. Security is ensured with AES256 Encryption. C321 transmitter can transmit video data in a non-line of sight environment up to 2-5km, depending on mode and frequency.


Using the leading COFDM modulation technology to overcome the analog technology and conventional modulation technology's limit of multipath reflection and occlusion, it can be achieved in the non-line of sight (NLOS), high-speed moving and real-time Transmission with high-quality images, especially suitable for complex environments.


The transmitter is with clear and stable image,intergrated design,double battery,perfect for NLOS transmission and mobile applications.

SD & HD compatible.
C321 with H.264 video compression.
