What is a military cofdm wireless signal transmitter?
A military COFDM wireless signal transmitter is a device that can send and receive audio and data signals using the COFDM (Msimbo Orthogonal Frequency Division Multiplexing) digital modulation technique. COFDM is a similar technology to DVB-T Europe digital tv standard, which can highly effectively compress the video and audio in TS stream by encoder and modulator, and at the receiver with decoder and demodulator chipset, it can perfectly get the real living video, audio, and data from the transmitter to the receiver.
This approach makes the signal more resistant to interference, kelele, and fading, making it appropriate for military applications.
Military cofdm wireless signal transmitter transmission distance
COFDM is the same as terrestrial digital TV stations. As long as the transmitter is placed high enough and within the line of sight, and there are no obstacles to the transmitter and receiver, it can support distances from 1 km to 200 km.

Military cofdm wireless signal transmitter Types
Gharama nafuu: For the cheapest model, we consider that some transmitters are installed on drones, and they may hit trees or other obstacles at any time and cause them to fall. Because they are cheap, they can be purchased in large quantities and used as consumables. If lost, they can be replaced. The receiver can be repaired with other transmitters for continued use. COFDM-912T, Ask for details on this model. 
HDMI 1080p: The cheaper model above only supports 720P resolution and CVBS composite camera input. If you have higher requirements for video resolution, you are recommended the COFDM-908T with HDMI input and output to support 1080P. COFDM-908T, Ask for details on this model.
Lowest Latency: For some medium-sized and large UAVs, the manufacturing cost of the aircraft is relatively high, and the transmitter needs to be made with ultra-low latency. The delay of ordinary wireless video transmission systems will reach 200~400 milliseconds, but the ultra-low delay wireless video transmission system can reach an astonishing 30~40 milliseconds, which is very suitable for high-speed and high-cost drones to ensure It can detect obstacles in time and make corresponding adjustments. Vcan1729, Ask for details on this model.
HDMI + CVBS both video cameras: In some drones or other security situations, two cameras are installed, which requires our transmitter to have the ability to transmit two videos at the same time. For customers with this need, you can choose our Vcan1726., Ask for details on this model.
Ethernet RTSP output to computer: Some customers also require that the receiver can not only output images to a regular monitor but also output images to a computer in real-time. Kwa kesi hii, the receiver is required to have a network port output that supports ONVIF and RTSP protocols. You can even play the launcher’s live video using a VLC player. Vcan1726, Ask for details on this model.
Signal Relay / Rudia / Extender: In some special applications, such as when there are buildings, mountains, or trees blocking the signal, we can place relays in the middle of the obstacles to extend the transmission distance and increase the signal strength of the transmission. Vcan1870, Ask for details on this model.
Solution for two-way transceiver demand: Everyone knows that CFODM is a one-way transmission system that can transmit video, audio, and data from the transmitter to the receiver, but it cannot provide signal interruption or packet feedback. Hata hivyo, in order to solve customer needs for two-way transmission, engineers can also make two sets of COFDM transceiver systems into one, so that the transmitter also has the function of a receiver, and the receiver also has the function of the transmitter. This is the COFDM transceiver. Mnamo 1886, Ask for details on this model.
UDP broadcast function: Vcan1816, Ask for details on this model.
