Military Backpack Portable COFDM Transmitter Two Way Voice Intercome 256 - bit AES Encryption
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.
Portable COFDM Transmitter System Application:
This military backpack system is special for man-portable transmitter enter into the area of the incident to gather information and signal transmission when in the condition of heavy obstacles, such as many building barriers, severe electromagnetic interference, remote mountain town or other harsh environments, which cause command vehicle can’t directly reach the site and forced to parked in vicinity.
LinkAV C322 TX+ LinkAV C331R RX Application:
The transmission path is: Manpack Video Transmitter C322 TX-1U vehicle mounted COFDM Wireless receiver C331R RX(Military police mobile vehicle with two way voice intercom,datas transmission,NLOS mobile video/datas transmission).
Communication vehicle - local command center - end command center. The local command center directly through the MAN or WAN transmission to the end command center, The command center can monitor the video signal through the monitor in real time,at the same time can use the network monitoring, access PC to browse video and video and other operations.
LinkAV C322 TX Portable COFDM Transmitter Specification:
The C322 transmitter is a body-worn dual audio COFDM video transmitter from Wireless LinkAV, it supports two way voice intercom, designed specifically for government surveillance, law enforcement, military command, emergency rescue, border control, internal security, critical infrastructure protection, maritime surveillance video transmission applications.
With the leading COFDM technology and H.264 encoder technology, the C322 transmitter enables viewers high definition images ideal for establishing rugged wireless video links in all complex environments including mobile and urban/ mountain /sea environments.
The C322 transmitter is ideal for applications requiring long term battery power deployments and Voice intercom, it employs low latency High Profile H.264 (MPEG-4 ) 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 images in a non-line of sight environment up to 2-5km, depending on mode and frequency.
