A good question. If Ocusync is better then why doesn't the P4P use it. Anyway this switching to 5.8Ghz is only good for people flying stock. For anybody using special antennas and amplifiers it is a complete waste. Also the 5.8Ghz frequency is worse when coming to penetration. More interesting would have been to use 900MHZ band or similar and introduce a long range/high penetration mode while still being in FCC limits.
What a luck. It seems that auto switching can be turned off.He Mavic uses 2.4GHZ and The manual wifi option, this is a low latency Link based on new LB tech, it does not use the auto switching to 5.8 in congested areas.
On the P4P DJI have come up with a Lb3 really, no wifi option but 2.4/5.8 auto switching depending on range and band congestion, interesting no where does it say the P4 is 1080P live feed either.
They are slightly different systems.
Right but extra antenna and amps are getting just too much of gear. Directional antennas do a good job in conjested areas. Also I wonder how stable this whole thing isThe ability to switch to 5.8 GHz could be extremely useful when the 2.4 GHz band is crowded, as it is quite likely to be in many urban settings. 5.8 GHz has about 8 dB higher path loss at 7 km but that could be made up with higher Tx power and/or higher Rx sensitivity on that band, or by additional antenna gain but those details are not available to us. Regardless it is very easy to imagine 5.8 GHz providing better range if the noise floor on 2.4 GHz is high.
I agree on most but external antennas and amps are not only to overcome noise. In EU with trees around you need external equipment or your connection is gone very soon. I tested 5.8ghz and it's not working well.I meant that additional power or antenna gain would be built into the controller by DJI to mitigate the additional path loss (additional power would be automatic, and the stock antennas could easily have higher gain on 5.8 GHz than 2.4), meaning you would not need anything external. Indeed, the whole point of moving to a band with less noise is to help eliminate the need for external antennas and amps (which are basically to overcome a high noise floor) in the first place. You can easily see this effect when comparing the 2 and 5 GHz WiFi bands in noisy environments. Also it's possible that RC devices operating in the 5.8 GHz range have higher bandwidth available, and that will further increase processing gain.
It will be interesting to see real-world test results once they start to appear and proof will be in the pudding, but with all the pollution on the 2 GHz band these days operation on 5.8 GHz has at least the potential for much better performance in urban environments.
No, but several other 5.8 systems. Dji surely got efficient handling in place but physics is physics. There are long range HD downlinks available today. Som with a range of more than 60.000ft 720p. However, dji does a good job for the money.You have a P4Pro already?
I have one but it's hard to make any real determination with a review unit and early software.You have a P4Pro already?
Only areas with a high noise level on 2.4 GHz will benefit from switching to 5.8 GHz, otherwise I wouldn't expect any improvement.. But where the noise floor is high on the lower band (fairly likely in dense urban areas, but impossible to test for sure unless you have a spectrum analyzer of some sort to know what is really going on) then 5.8 should perform better.At the same time, DJI doesn't add things for nothing - so maybe areas really crowded with 2.4 will benefit?
