HD Body Worn COFDM Video Transmitter UHF Digital Microwave Low
Wireless COFDM Video Transmitter Anti-electromagnetic
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
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
The transmitter is with clear and stable image,intergrated
design,double battery,perfect for NLOS transmission and mobile
SD & HD compatible.
C321 with H.264 video compression.
