4. Introduction HD COFDM transmitter
HDMI or HD SDI COFDM transmitter and receiver is one set of NLOS or
LOS HD video audio wireless transmitter and receiver.
COFDM transmitter transmits mobile data, including audio, video or images
over long range
COFDM HD video wireless transmitter and receiver is with the core
technology 4th generation mobile communication COFDM module and low
delay full HD 1080P technique, COFDM wireless video transmitter can transmit
high quality and stable image under the condition of fast moving or many
buildings as obstacles (NLOS) with carrier velocity greater than 450kph
Wireless transmitter and receiver are widely used in public security, armed
police, fire, field armies, other military departments and broadcasting, urban
management, civil defense, transportation, customs, oil, mining, water,
electricity, geology, finance and other relevant state departments
