When DJI released the Mavic Pro they decided to change the transmission system that communicates between the remote control and the drone.
The new system is called OcuSync and it has some impressive capabilities worth looking at.
Of course, it also has some differences and downsides to the other transmission technology in the DJI Lightbridge family.
DJI had some cool ideas when they were designing OcuSync, because they had plans for the DJI Goggles.
OcuSync was developed with the capability of supporting multiple outputs easily.

Let's go a little deeper and have a look at what the specs are of the Ocusync system.
Ocusync can transmit video at either 720p or 1080p.
It depends on the situation, but in general OcuSync will use 1080p for close range transmission and 720p for long-range transmission. Which makes sense, as it is harder to transmit so much data at longer distances.
When things are running well, at a shorter distance and low interference, you can get photo and video downloads at 40Mb/s.
THE DJI Mavic Pro using OcuSync starts by scanning for any local interference and then makes a decision between three transmission channels: 20MHz mode, the 10MHz mode, and the lowest priority 1.4MHz mode.
During flight it will then automatically switch between channels (within the chosen mode) if it notices any interference.
So, the system is very robust.
A big issue with any transmission system is the latency. Which is the amount of delay you experience.
The DJI team have done a great job with the new OcuSync and achieved these values:
Note: 160ms-170ms from the Mavic’s camera to your device screen under ideal conditions.
OcuSync has a great transmission distance and I have seen a lot of videos on Youtube where people have flown these distances.
OcuSync has a range of up to 4.3 miles (7 km).
