10KM 100KM Small Size Portable Mini COFDM Transmitter
Product Description:
HMMIT05UP only weights 80g that can transmit 10- 15km from air to ground. This model uses modulation technology that encodes orthogonal frequency division multiplexing to support applications that break the line of sight limitation, this modulation is a fully utilized technology in radio spectrum resources.
The core of COFDM technology is that it can have very good immunity against noise and interference, diffractive and penetrating obstructions, with narrow transmission band and strong anti-multipath interference capability
and anti-multipath fading capability, enabling non-line-of-sight (NLOS), high-speed transmission of real-time images in high-speed motion
image.
Key Feature:
1. Light weight 80g for 10-15km long range transmission
2.1080P 60fps HDMI transmssion
3.40ms low delay real time transmission
4. Long transmit distance from 10km up to 100km
5.Strong ability to avoid obstacles, no need to rely on the network
6.Easy maintenance, saving time and effort
