2 years on and we have ocusync in mavic mini 2
I know it’s incredible.
Finally a very good explanation! I was already looking for something like this since months now! It was very difficult to get any information about the transmission system in detail. What I've learned is first, that WiFi isn't a good choice for flying drones. I experienced that with my Parrot Bebop1. Not I got the P4 with its Lightbridge and a Mavic Pro 1 with Ocusync. And Ocusync - from my point of view - works A LOT better than Lightbridge. No freezes, just more stable
Very informative! Also great to see in a scope graphics how the spread spectrum frequency hopping looks. Thanks!
Great video! I was looking for something like this. I'm just amazed at this Occusync technology where they can send large data on a long range...
Amazing! Occusync is amazing and I think occusync is better than lightbridge in range and quality occusync 2.0 has such a high bandwidth I bet any benefits will be “ported” over to occusync.
Can you explain the “enhanced” WiFi based system in the Mavic Air as well like this? I been amazed at how good the WiFi is on that little thing (in FCC mode). I’m getting over 2 miles on WiFi.
I live in a rural area and on my Mpp I still get 1080p live view at 7+km out. So the "short" range is not always so short😁
when i try to go a bit outside the city i have unstable connection with my spark after 500m! i might get a mavic next time ;)

Hi there, I live in the (pheonix, Arizona) population 3+million and I get 2.5 to 3+ miles. I usually stop and have to turn around do you the battery RTH. Check out my friend. Have more

Hello New subscriber I was hoping to find more data on the Ocusync before purchasing Mavic Pro or go directly to Mavic Pro 2 or Zoom. I’m glad I came across this in-depth excellent video.
Great post. Thanks for ALL the information and effort expended to keep us informed. I'm a new subscriber and will support you with purchases when the time comes. Thank you, again.
Excellent video, very informative. Thank you for your time to put this video together.
Thanks for the explanation of the two systems...… I found it very helpful to understand the current limitations and the direction for the future.
cant wait for the fw update for my white goggles so I can use them with my new mavic2 pro
Wow what a great and comprehensive video on the transmission systems of these drones thanks for the info...
Very informative, thank for for the detail and easy to understand diagrams!
Thanks
A smart solution, I bought one for my Inspire1
I'd like to point out that even the first version of ocusync used in Mavic Pro performs much better than latest Lightbridge used in Phantom 4 Pro and Inspire 2.
Exactly...i get 2x plus the video transmission range on my 6 year old mavic pro
Well, that went over my head. I wish there was a class I could take regarding drones.
A good comment
Thank you so much for so thorough and clear information. Best Regards from Spain!
Very well explained. Well done and thank you.

Absolutely Great! Thanks!
WOW, Thanks for the comprehensive and technical explanation. I also really appreciate the accessories compatibility chart.
Sadly I lost my original Mavic PRO, by flying around a Ferry in high winds. The RTH kicked in, but the Mavic PRO, struggled returning against the strong head winds. It entered auto land once the battery got to about 10% and descended into Port Phillip Bay near Melbourne, about 200m off the shore. 😭
DJI care refresh said don't fly once you have strong wind warnings on the DJI GO4 APP.
So I have waited about 7 months to find out weather my batteries, controler, White DJI Goggles, etc will work with the Mavic 2 Zoom and Pro?
Your video is much appreciated, answering some of my questions and explaining how they are limited to 2.4Ghz.
Did you try sports mode to return home?
@@bobbrown8661 Yes, I tried switching into Sports mode, once I realised I was in real trouble. I was using my Sony Android Mobile phone and experiencing bad Lag on the DJI GO4 APP.
The RTH kicked in at 30% battery displayed on the mobile phone. The Mavic climbed to 70m from memory and probably into stronger gusty head winds than I was experiencing on the beach. Unfortunately I didn't confirm that % on the controller screen, which with Hindsight was probably was more accurate than the mobile display? Suddenly the battery level dropped to 13% and I realised my Mavic Pro was in real danger. The Mavic didn't seem to change into Sports mode and once it dropped below 10% the Auto Land worked perfectly, into the Bay.
Excellent video and explanation - thank you.
Fascinating video. Have you done a similar one showing the differences between WiFi (for drones) vs Ocusync? I'd be especially interested in the spectrum graphs, power outputs and any other features that make Ocusync more reliable than standard Wifi. Thanks!
Excellent Video. I have Subscribed.
WOW!! How do you know all that??????
Another great post, thank you very much.
congratulations, happy to have subscribed to your channel
ty ty! I'm very relieved to find out the white edition DJI goggles I bought will work (eventually) with my MP2.
Bbooj Smooya Yes the Firmware has now been release simply connect them to DJI Assistant 2 and update them and you will be able to use with the Mavic 2.
Thanks for the heads-up, @Mad RC! I just updated my goggles to .500 firmware and they now work! A "Mavic II" option appears in the link menu. Of course, luck would have it that today the wind here is over 25mph (40kph) so I couldn't test it outside, but I was able to test fly it in my basement (It's large and empty) and it worked fantastic. Thanks again!
13:02 Dual is spelled D U A L
Liked the video though
hahaha
4:20 Weak was spelled week.
Interesting info....good job!!
Great information. I learned something.
Great in depth information, would really like to hear your thoughts on the new dji fpv system and how they have achieved such low latency.
Very shortly overview to come.
very helpfull video, thanks a lot, question, can I use a normal WIFI repeater to repeat video signal to the radio? I intent to fix the WIFI repeater on one specific position, it will catch my signal and send and receive data signal blocked by a obstacle, thanks again.
Sadly no due to the way it works, it will not be able to cope with the FHSS and OFDM. Most Wi-fi repeater actually are just received and access points in one so they actually connect to the network and the resend it. This will not work with Ocusync.
Informative video!
Very comprehensive
Great video. I am still a little confused at how it gets extended ranges despite the FCC restriction of 26dbm max eirp? Does it have to do with the compensation from the FHSS gain due the hopping bandwidth being much larger than the singe carrier bandwidth?
Hello. Your information is good. Please guide me to an external antenna, which means to install on the roof of the house for this ocusync 2.0 router for its use of the Dron mini 2. Thank you.Because I want to control it from inside the living room
Hmm...noob question here, but is Ocusync radio transmissions? Or is it some kind of microwave transmission like wifi? And should one be concerned with transmission radiation from the controller, with either the ocusync or the traditional wifi signal with cheaper drones? Does ocusynk mean more radiation because of the longer range of the tecnology or does it work at a similar effect as the wifi variants? Sorry, but I am a control freak when it comes to these things. :-P
The Phantom 4 Pro V2 Now supports Occusync 2.0 via a firmware upgrade
Yes correct this is something DJI ha e just done, at the time of making it was the hybrid version but now it’s been fully updated to 2.0 and it just shows the benefits of Ocusync over LB that it’s able to be upgraded.
Thanks mate good vid
I like it!
Good explanation - One question.
From my decades of flying RC and FHSS radios, it was always considered good practice to fire up the RC first so that the TX could hop around and look at how noisy/busy the band was before firing up the aircraft/Rx.
With Occusync 2.0 is there any advantage in powering up the Remote first or the aircraft first to allow the system to 'look' for interference and settle on the video carrier in the least noisy part of the band?
I would always recommend having the RC on first however from a radio point of view it really does not make a difference , when the craft losses RC signal is jumps to a failsafe mode where it constantly hops between one channel on 2.4 and one on 5.8ghz, its hopping between bans back and forth every second or so until the signal is re-established with the remote. One it does then with in 2-5s it then will look at the band and then jump to a free section of the band.
Great explanation, thanks for posting, something else I have always wondered is why there are 2 antennas on my MP controller and what the purpose is of each one?
One is TX and one is receive generally, it is diversity I believe but it duality defaults to a tx and rx config, usually LH as you hold it is transmitting.
Nice one Ian interesting as aways
Hi, thanks for a nice explanation ... :)
I live in Norway and have limited reach on my Mavic2, ce mode in Europe. Do you know the possibility and switch to FCC mode so I get more range? Mvh Jan ...
Best yet 👍
Thanks
Thank you! A very technical approach, I appreciated it. I am guessing that you have a good knowledge of telecommunication modulation and hopping methods. Can I ask you to make a video, about how drone jammers work on DJI products? Like, hijacking home location and force a drone to land somewhere else.
This is a very interesting subject. The jammers for the most part do nothing special apart from disrupting the aircrafts signal from and RC and the GPS, this means when the signal is lost the craft has to resort to landing on the spot as it’s basically in Atti.
While you will see some videos showing them controlling it down to ground this is mostly nonsense, they are simply overloading the receivers in the control and GPS and then relying on the crafts default behaviour in that scenario to land on the spot. However if a user has set it to hover then it will behave differently.
There is a huge amount of smoke and mirrors around this side of things and while hacking the control like is possible very few have that ability in reality outside of government.
There are some custom made jammers in the Middle East region, and I would be glad to send you a couple of photos of these systems. You mind if I have your email? or I can share mine with you and would be thankful to have a replay email from you, then I can send you back the photos. Not sure if you are interested to know or discuss the issues.
Great video , thanks
'Dual' as in 'two' or 'twin' is spelt with an 'A'. 'Duel' as in 'fight with weapons' has an 'E'
Yes a old mistake I can’t correct now sadly
Excellent!
Where does the M200 fit into the picture? It was interesting to see your patch antenna test a short time ago.
Jeff Street lightbridge 2.5 basically on the M200 series like the I2.
Excellent video.
There are so many bullshit videos out there that claim Occusync is just regular Wifi technology with automatic jumping of channels if there is too much interference.
Which is utter bollocks!
Your video shows what i have been expecting, occusync uses multiple frequencies across the band simultaneously.
How does it achieve that range though? I was sitting in my back yard under a bunch of trees sitting next to my house and flew 2 miles with no signal problems on mavic 2? Weird question but I noticed obstacle avoidance attracts birds, can anybody explain this
Nani
Oh I just replied to a comment from a year ago
Wowwww.hats off
"Can you use the CrystalSky monitor with Occusync?
But now in 2020, accusyn 2.0 is now in a smaller drone (mavic mini 2) 😊☝️
Hi, nice video. Do you think that occusync 2.0 can provide higher video bitrate than 1.0? It seems to me that video in white Goggles is pixelating more than on phone in Mavic 2 RC controller. I am thinking that it is caused becuase goggles has older processor for decoding video... basically because they are only on occusync 1.0... What is your opinion? Thanks.
I do think the white goggles are maxed out with Ocusync 2 tbh.
How come there is no 'open' alternative to Ocusync? Something makers can use to achieve these incredible video transmission results that these drones manage to do?
It’s all very proprietary hardware and software.
@@MadRC Just in case others were wondering about that topic, I now found the OpenHD project on github, which is a kinda of "open Ocusync". It can even (ab)use COTS wifi adapters!
Will it work for the mini2
Dual.
If Ocusync 2.0 has encryption, can you disable it? Disabling it would allow a faster signal transmission.
No it’s always on.
Good video. Please can you confirm what the RIGHT hand antenna is for on the Mavic controller? I've been out 8km and completely covered up the antenna and still have full control and excellent video quality. I then covered the left one and lost all signals. Very confusing.
One is TX and one is receive generally, it is diversity I believe but it duality defaults to a tx and rx config, usually LH as you hold it is transmitting.
Mad RC I think its for Antenna diversity, if the craft is in front of you, the left hand antenna is in use, if the craft is behind you, it switches to the right antenna.
Hi, do you have info on the spectrum for ocusync etc, wifi connection eg 802.11 eg Mavic Air/spark conforms to that standard, so it uses standard wifi channels. I notice ocusync uses the same frequency 2.4/5ghz. I have heard people saying it kills your home wifi when you fire it up. Is it built on 802.11 at all? 2.4 is a very busy frequency.
It’s using the same licence free band of frequency’s as Wi-fi however it’s not using the Wi-fi protocol. It’s an OFDM video signal and as such its much stronger than the Wi-fi and will generally kill any Wi-fi around it in close quarters.
Hi, sorry to bother you on a different subject to what is being discussed but I wonder if you could advise me if the Mavic Pro or zoom is compatible with the Crystalsky monitor please? I’ve seen a couple of clips on YT were the guys are saying that they’re expecting an update to remedy the problem. From our previous conversations I know you have a Crystalsky monitor and find it strange that you haven’t mentioned any problems using it. Thanks. Peter
peter hughes it’s not officially compatible yet, new App should be coming very soon for it.
Great, thanks. Seems rather counterproductive to introduce a new product with all the razzmatazz and not make it compatible with one of their flagship products. Take care and catch you later. Peter
What are the small benefits lightbridge on the inspire has over ocusync?
Now they are little, originally a lot of the deciding for the live feed was handled onboard the RC but that was later moved to external, the one main one is that as its still very much hardware based having things like HDMI output and SDI is much simpler to implement than on Ocusync.
What type of encryption does it use?
AES on Ocusync 2.
The two image gives the impression that Lightbridge is better for Drone control and Ocusync is better for video, is that true or did I get completely wrong?
PoyaSweden they are from different scopes so they look slightly different. Realty is from a carrier point of view they are virtually the same.
@@MadRC
So chosing a drone with lightbridge is almost as reliable as Ocusync when it comes to drone control and live video?
Ty for helping
I am trying to use 2 sets of goggles with my Mavic Pro, 1 set for me and one set for a friend to enjoy the flight with me but I am struggling. Do I need a second remote controller also? Help appreciated.
robrow no you can use 2 sets with the Pro no problem see the manual on how to bind them.
So confused on this,my question is do you turn ocusync on,is it always running,?
No its the communication link on the Mavic 2,Mavic Air 2 and M210 V2
Occusync is a gift from God 🎁
That it is :)
is ocusync air fpv module is compatible with withe google?
Yes and no, it does not have the 5Ghz hardware and it was not playing nice last time I tried it. It should technically be but there were some issues so I’d would not advise it.
not clear I have the white one
can't they offer ocusync to mavic air since it was software based?
Yes it does not have the hardware, while it’s more an SDR it still needs dedicated hardware to do it that the air does not have.
How is an FPGA based radio ”not upgradable”? That makes no sense.
obviously the FPGA can be programmed to do what ever they want to a point but only early Lightbrige systems used it, later revisions used custom hardware so that all went out the window, there are versions of the Phantom 3 and Inspire 1 that have FPGA and custom hardware,they also don't have the necessary overhead to be able to decode 1080P like the later ones and like the original Ocusync it was not dual band.
Still don’t understand why ocusync wasn’t used in inspire 2. The video feed from the original mavic was so much better than the feed from the inspire 2
smoak888 DJI product teams tent to be separate from each other, ocusync was new and not fully proven so I suspect the I2 team went with what they know and did not want to risk the newer unknown technology on the I2 for pro users. While Mavic Pro did come first they were likely developed in parallel in the background totally separate.
Mad RC guess we have to wait for inspire 3! 😬
