A few more tests made yesterday, as I have seen some video in urban area at 1000+ meters...
FACT for CE only (I cannot test FCC in Europe):
1. You can get 1000+ meters in high density urban area ! Only that you need to climb on roof or in a tree, in order to have the RC higher than buildings.
2. As long as you stay with your RC above buildings and with drone another 30-50 m higher, the signal is clear in 1000+ meters.
3. You are not a pigeon and neither a monkey, so in 99% of cases you cannot go to a roof or climb a tree for point 1 and 2.
4. At the moment you are on ground, even if you have direct sight with drone, but signal is traversing noise areas from routers, you cannot get more than 400m. (same area where I was on top of building).
So the issue seems to be that the drone is very sensitive to signal received and/or is not always changing to a free channel. I did not tried manual change of 2.4 ghz channels, don't know if still works to pick manually a channel ( i think is just letting you choose the band and that is it)....But from what I observed, any interference in direct sight will kill signal fast with too much noise.
Not the same at other DJI products, in same area I was filming with Mini 2, Air 2 and Air2S for a time, no issues like this observed. (perhaps antenna location have some to do with it?)
All time the new RC was aligned directly to drone, last firmware, and so on...
This is why we see tests with different ranges, the ones that get a lot of range usually try to cheat (intentionally or unintended) by climbing a high area, a roof, or goes in areas where in direct sight don't have any noise (as 2.4 Ghz routers have a lot less power at 30-50 m away from building where it works). |
