Transmission optimisation

[Kerrowman]

I have come to understand how the mini will select the best comms channel on Auto and that channels 1-13 use 2.4GHz and those above 5.8GHz.
My question is does the mini on Auto prioritise the channel and frequency for maximum range (and hence signal strength) or for minimum interference?

Also would setting a manual 2.4GHz channel before flight remain good for the whole flight or could that channel become less ideal during flight and so limit range?

Thank you

Range and interference are related. It is not either or. The drone attempts to use what is best at that particular time and location, and will switch if it can find an improved situation. Generally, these solutions are time dependent, so locking to a single frequency will not give the best results over time.

Ok thanks. From what you say keeping it on Auto and hoping that the channel used is operating on 2.4GHz will ensure the best range.

Can it switch channels/bands mid flight if in auto mode? In manual mode it requires a WiFi transmission system reset, and hence you can't do this mid-flight. I'd always understood that you commit to a specific channel for the entire flight, either manually selected or letting auto mode pick for you.

I have sometimes used manual mode and selected a 2.4ghz channel with minimal interference to get better range where Auto mode had previously selected a 5.8ghz band.

It's not a clear cut answer on what is best, as that really depends on the circumstances at the time, as Dave has said.

I don't think that always using 2.4 ghz is going to be the most optimal choice in the real world. 2.4 is far more congested in the big east coast cities. As far as I can tell, the drone picks the best solution available at that point in time or location whether or not it is 2.5 or 5. I have done a lot of tests in Cambridge, Ma, with a rf signal meter and various drones, and the auto feature does a great job finding relatively clear frequency ranges to use.

I have not tested with Occusync based drones, so it may be different with them.

Does the drone changes from 2.4 GHz to 5.8 GHz even during flight, or it pick one before the flight and remain on that during flight?

So does that mean the Auto mode with the Mini can switch channels mid flight?

Thankfully I’m in a very rural area with minimal interference.

During my tests it switches to whatever seems most free in real time in flight, whether or not it is 2.4 or 5

it doesn’t change frequency during the flight, that’s occusync
