How do you guys get such long ranges? I've done two flights thus far with my Zino, and I get connection losses already at 40m altitude! I just ascended upwards from me, the video stream starts stuttering and eventually I get connection lost and the drone switches to RTH.

Note that I've never bound my phone's WiFi to Zino, so that shouldn't be an issue. I'm in a scarcely populated area so not that many Wi-Fi networks around (and certainly not running at 5.8GHz). During 15 mins of total flight time I've lost connection at least 4 times. The last flight I did with the Phone Wi-Fi turned off completely.
Because you are flying outside the WiFi signal envelope and we fly within it :) . If you fly straight up you end up in the hole. Always have the flats of the antennas 90 degrees to the Zino i.e. on the B axis for maximum range.

Hello,

Thank peterkng kindly suggestion.

If get the disconnection issue ,the Zino will switch to RTH.

Personally, I have already made more than 10 flights to 980m distance before loss of signal, when at the height I am 150m to watch the French law. I climbed test at 300m over a distance of 880m also. No problem. I am on iphone 8 more for info. And whatever the phone, do not bind the ZINO WIFI phone, it is useless and it disturbs more.
The 2 antennas must be parallel to each other and then oriented perpendicular to the direction of the drone.

I was flying yesterday and there was a much better range. It was 750 m.😁 But then my camera was turned off.
When I flew 250 m. I had 4k camera turned on.
Maybe my memory card isn't good enough?
( I have San Disc 32GB, write speed 10MB per sec.)
What memory card you have in your Zino?

Ya think :D
That is a class 10, u1 or V10 suitable for Standard and HD not 4k.

You need as a minimum a u3 (V30) preferably a V60 SD Card for 4k.

64 Go V30 U3 A2 minimum !!!
V60 A3 if possible

I think what 'me_3ce942yJox' was getting at is different.

He said he got a good range of 750 m when the camera was turned off (meaning not recording video, I suppose) and he got only 250 m range before the Zino disconnected when he was recording at 4K.

Now he is wondering if this may be due to his memory card not being good enough.

Well, unless there something exceptionally weird going on within the Zino's electronics, the SD card should have no effect on the maximum WiFi transmission range that can be achieved.

Is that "write speed 10MB per sec." something you measured yourself or do you just mean your Sandisk card carries the Class 10 logo (C-like circle around a "10")?

My experience is that Sandisk microSD cards usually perform much better than their classifications suggest.

If you have a computer running a newer Windows OS version, then an easy test would be to copy a large file (e.g. a video file) from the computer's HDD/SDD to your Sandisk microSD card and it should show you the achieved write speed in MB/s while the copy is in progress.

I've been thinking about the max range specified by Hubsan for the Zino, and the tests that people have done. What is surprising is that (the ones I've seen) the range seems to be as quoted at 1000m. Some even speculated this was geofenced.
Anyway as I had a few minutes to spare, I thought I'd check out the specsheet for the Atheros AR1021x used in both the Controller and quad. The receive sensitivity is quoted (at 5.8Ghz/6Mhz rate) as typically -90dBm.
We also know that the power output has been measured at typically 12dBm, and the antenna provide 2.9dBi gain.
Throw all those together, and knowing the free space path loss at 5.8Ghz (107.72dB/Km), we can calculate the typical range.
And guess what we get?
1100m :-)
No coincidence there then.

and would there be any way to extend this distance?
