COFDM Wireless Downlink Transmitter

Our COFDM wireless digital video transmitter is a superior miniature wireless video transmitter designed to capture real-time, high-quality video from Point View Cameras, UAV/UGV/Body Cams/Concealments, and sports cameras. The transmitter has HDMI, SDI, or AV inputs with COFDM modulation technology and H.264/H.265 encoding for high-speed motion and NLOS (non-line of sight) video audio transmission with low latency. Our COFDM wireless transmitter provides up to 27dBm/30dBm/34dBm (depending on the model) of power in a small metal case weighing less than 150 grams, allowing for long-range, dependable HD video transmission.

• H.264/H.265 video compression and COFDM modulation

• Full HD resolution, 1080i/P @60fps; AES encryption for maximum security;

• Design that is modular and highly integrated;

• Signal transfer stability in NLOS and high-speed moving.

• Working frequency, bandwidth, bitstream rates, RF power, and other parameters are all adjustable.

We now have several COFDM transmitter models ready to ship (in various RF power and video input interface configurations with the same technology solution, as listed below). We can also quickly customize wireless COFDM transmitters based on your specifications using our modules.

Our COFDM wireless transmitters are made up of three modules: an H264/H.265 video encoder module, a COFDM modulation module, and a power amplifier.

Our COFDM transmitters all use the same modulation module (Our RCB Module), as well as the same H264 video encoder solution in different board models.

All of the transmitters can be configured via control UART with the Sihid Config Panel or a Windows PC.

Performance

Video latency: When our COFDM transmitter is paired with the receiver, the video(1080p60) latency from the transmitter's input to the receiver's HDMI screen display is approximately 0.2-0.25 seconds.

Wireless transmission range: This is relative to many conditions; the data below is provided solely for your convenience.

The NLOS (non-line of sight) transmission range is approximately 1km to 2km when our COFDM transmitter with 1W (RF power) is paired with the receiver, 6MHz bandwidth, center frequency 590MHz, 5 dBi Omni antenna with 2 meters to the ground on both sides.

When a 1W (RF power) Our COFDM transmitter is paired with a receiver, the LOS (line of sight) transmission range is approximately 10km to 20km with a 6MHz bandwidth, a center frequency of 590MHz, a 1.5 dBi Omni antenna on the UAV (flying height 100 meters), and two 7 dBi Omni antennas about 2 meters to the ground.
