3D Link provides robust video and control channels for drones and robotics in Non Line-of-Sight (NLOS) conditions.
3D Link is based on enhanced OFDM technology able to generate not only a high spectral efficiency waveforms but also a direct sequence spread spectrum (DSSS) waveforms. This unique feature gives 3D Link an ability to support high throughput up to 64 Mbps in video channel and superior robustness in control channel.
Video channel can be easily connected through Ethernet interface. Ethernet, RS232 or CAN interfaces can be used for control channel.
3D Link supports point-to-point, point-to-multipont and relay net topologies. For high robustness it is equipped with algorithms for suppression of narrowband and pulse interference. 3D Link supports also such interesting features as an adaptive transmission power control, TX-RX range estimation and IPv4 frames routing.
Onboard unit of 3D Link weights only 89 grams (3.14 ounces).
3D Link was designed for maximum possible range in mind. For drone flight over flat terrain at 50 m altitude and with standard antennas set 3D Link can communicate up to 20 km in video channel and up to 28 km in control channel. For flight at 500 m altitude range achieves 62 km and 70 km respectively.
3D Link supports relay mode for a range extension and also for bypassing of the shadowed zones in urban and industrial areas. In this mode you can get video not only from distant drone but from relay drone too.
You need not more separate modems for video and control channels. For video channel 3D Link uses a high spectral efficiency waveform able to reach 64 Mbps rate in a 20 MHz bandwidth channel.
A maximal robust DSSS waveform is used for control channel where −122 dBm RX sensitivity is achieved and interference is suppressed.
3D Link supports communication to several drones from one ground station. You can get video from several drones and control them simultaneously. Opposite configuration is also possible when one drone is controlled from several ground stations and send video to them.
3D Link uses technologies that supports robust communications in NLOS conditions between drone and ground station. Many algorithms in 3D Link collect components of dispersed signal and correct errors for robust control and crystal clear video.
Even for 800 km/h drone velocity you can be sure for reliable communication.
