Confuddling range test results

[PyroProdigy]

Google doesn't provide answers and facts itself.

Search engines are a means of identifying multiple publications from multiple reliable experts and institutions. I'll trust the opinion of a group of experts (like the American Medical Association) over the opinion of a single supposed expert (such as a former heroin addict).

Which is why I attached a link to several articles and peer reviewed research from several experts.

And Who exactly is a former heroin addict?

You and I are on the same page with respect to Google answers and signal propagation. That comment about Google was referring to the post you quoted in post #9 about just trusting Google. I should have been clearer about that.

And Who exactly is a former heroin addict?

The expert running the Department of Health and Human Services.

Lol ok I was just confused because that seemed to come out of nowhere but I get it now. And that is something I did not know!

Wind, the sun and clouds also can effect signals. Many people don't know what the wind can be a big factor with signals of all kinds. Radio wave interface as well.

Chemtrails too.Deep state interference.

Sometimes I question the WHOLE 'acceptable' wisdom of Line of Sight by the FAA when droning.

I mean the drone has Crystal clear vision - at the Point its Located... some of the Best cameras in the World - couldnt do Better at range...
Id call that better than VLOS ....
Way Way better than You with Binoculars ... LOL

In fact - based on this - even Internet 5g/4g has more clout than the Human trying to save the drone - by straining to see in the distance

But, Ok- this is a debate for another day... (smiling)

But even a Die Hard "FPV ADDICT!" would concur ...

This thread is pretty derailed at this point but honestly ? I think anyone who claims to maintain VLOS 100% of the time is lying. I'll say there are probably exceptions to that statement but they would probably be the Part 107 guys out on a job and a small minority of recreational flyers. Even with my glasses on, I lose sight of these things after a few hundred feet.

As stated, my tests and routine flights are done over uninhabited areas ( woodlands and farm fields ), I wouldn't fly like that over a more populated area.

I'll also say that after seeing a local pilot flying below 500' AGL, I do have a new appreciation for the VLOS/BVLOS rules. I made a post about that pilot and got **** on pretty heavily here for it, but now I have video proof of this happening that I can share once I find a place to post it. Seeing a small engine plane flying directly overhead and basically having your house buzzed while you have drone in the air nearby is not a pleasant thing.

The VLOS issue is completely irrelevant to your post. Don't be deterred by it.
You weren't asking about FAA regulations. The most relevant factor to optimizing signal penetration and the number of the signal bars is clear LOS, meaning no physical obstructions between you and the drone. That does not require the visual acuity to actually be able to see the drone with your eyes or even binoculars. Obviously, if you can see the drone, there are no intervening obstructions to LOS. Flying from a 300 foot tall hilltop over lower ground can provide LOS out to the horizon some 20 miles away, but the Air 3S signal maxes at just over 12 miles away, far beyond the flight time of the battery to also return home. More details on improving your signal range in each direction can be found in Post #33 above.

=========

The DJI Air 3S has a maximum FCC signal range of 20 kilometers (12.4 miles)in an unobstructed environment, free of interference. However, this range is heavily dependent on interference levels, with the transmission distance decreasing to approximately 1.5-4 km in urban areas and 4-10 km in suburban areas.

Factors affecting range:

• Interference:
  Higher levels of wireless interference, common in urban and suburban environments, will significantly reduce the drone's signal range.
• Obstructions:
  Obstacles like buildings and trees can block the signal, further reducing the effective range.
• Environment:
  Open spaces with low interference, such as rural areas or coastal regions, will allow for the longest transmission distances

Chemtrails too.Deep state interference.

This article found a statistically significant effect of wind speed on data transmission losses, showing a measurable correlation

This is a notable study that found wind has a "marked effect on radio signal," especially when propagating in a similar or contrary path.

The articles are from peer-reviewed journals.

Indirect effect of wind, not a direct effect.

to the west, I can sort of understand losing signal quickly because there are some fairly thick stands of timber in that direction,

In all other directions except a northerly directions, the wooded areas are rather thick/more dense, I suppose thats the most likely explanation

The only way that forested areas will negatively affect signal strength is if you have forest blocking the signal.
Flying over forest won't have any effect if you have a clear, unobstructed line of sight between the drone and controller.

Wrong.

Correct, sort of. Wind, in and of itself does NOT have any effect on the strength of radio waves. However, wind does play a large part in the attitude of a drone in flight and changes in the attitude of the drone directly effects the position and direction of the antennas on the drone, which can make a HUGE difference in the useful strength of the radio signal to and from the drone while in flight.

You can read the scientific papers and I attached in previous posts. I said nothing about altitude and wind. That's obvious that the orientation of the drone itself will have an effect on the signal. That's not something that 'many people don't know' including you and others.
Did you read anything past that at all? Wind effects the atmospheric conditions that effect signal. Not even crazy wind either. A 5 mph wind can do it.
This was all explained to me in depth by a Cisco network engineer.

You are you on 365, 24/7, 1440 minutes a day. I highly doubt you actually have time to fly a drone. Anyone would be hard pressed to find a thread you have not commented on.
Get a life.
A network engineer has loads more experience than you do in this matter. Guaranteed. Cisco doesn't give out that certification lightly. There are only a few people with that title and cert in the entire country.
All you do is Google stuff. We can all do that ourselves now a days. No need for your 1¢


Btw....You would never act this way in real life. No one would put up with it.
But free to do as you wish on the Internet I guess.
