What Is OcuSync 2.0 – DJI Drone Technology

What Is OcuSync 2.0 - DJI Drone Front View

You may be wondering what is OcuSync 2.0. When the DJI Mavic Pro first came out, DJI wanted more robust and stable connectivity from the drone to the controller.

So they use radio frequencies that get transmitted between the controller and the drone, which is called OcuSync. It’s a step-up of an upgrade from DJI’s previous wifi signal and the LightBridge transmitters.

Previous Version of the OcuSync

The previous OcuSync 1.0 was incorporated within the Mavic Pro and the Mavic Pro Platinum drone models.

In addition, the advantage of OcuSync 1.0 was it provided better connectivity and can transmit 1080p resolutions from short distances and transmits 720p for longer distances.

Overall, it’s easier to transfer data between the drone and the controller, which makes sharing video easier, with a 40 mb/s speed when downloading.

How OcuSync works are that it searches by using three channels such as 20MHz, 10Mhz, and 1.4MHz. While the drone is in the air, OcuSync scans all three channels automatically, and the drone can detect any interference between signals.


What’s very impressive is that OcuSync can work up to 7km in the distance, meaning data transferring and responsiveness remains excellent between the drone and controller.

What is the Difference between OcuSync 1.0 and OcuSync 2.0?

Further upgrades were made once the DJI Mavic 2 models first appeared back in 2018, and a significant upgrade was made, which was OcuSync 2.0.

In addition, the most significant advantage that the OcuSync 2.0 possessed was able to transmit 1080p for both short to very long ranges.

Another considerable benefit of OcuSync 2.0 is that transmission speeds were significantly different. However, downloading remains the same as the OcuSync 1.0.

Transmission in OcuSync 2.0 uses both 2.4GHz and 5.8GHz, which provides the drone with more options when there are multiple signal interferences. Also, latency didn’t improve but shouldn’t be a significant issue.

What’s the Difference Between Wifi and OcuSync?

When using Wifi signals between the drone and the controller, there’s a great chance you’ll experience signal disruption if there are other nearby wifi signals within your surrounding area. And using wifi, the transmission ranges are shorter, making wifi less reliable than OcuSync or LightBridge.

What’s the Difference Between LightBridge and OcuSync?

Lightbridge will provide you at least 7km of signal. Additionally, the LightBridge technology was first implemented within the DJI Phantom 4 drone models. The new technology was a step-up of an upgrade in video and image transmission and the direct connectivity to the drone.

Thoughts and Conclusion

The OcuSync technology is top-notch, and DJI is at the top when it boils down to signal transmission. So hopefully now you know what is OcuSync 2.0.
