2.4 GHZ / 5.8 GHz / Dual-band

[Max Headroom]

My Mini 2 SE has finally arrived and i am going through the settings to to make sure my first flight isn't a disaster could someone explain what setting is best under Frequency i have the following options 2.4 GHZ / 5.8 GHz / Dual-band could someone also give a brief explanation of what they are, thanks.

Most of the time you want the default, dual-band, which swaps between whichever signal is strongest wherever you are now.

2.4GHz has longer range, better penetration, and is less affected by obstacle occlusion, but is more susceptible to wifi interference in built-up areas. It is more directionally forgiving as well.

Whereas 5.8 GHz has a shorter range, but is much better in commercial or residential areas where there is a lot of nearby WiFi signals present, because so much fewer of them will be in the 5.8 GHz range. But this is more directional, so suffers if your aerials are not aimed at the craft, and is particularly bad if there are walls or trees between you and the craft.

Not sure it's the same on the M2SE, but on my M4P that page is quite useful in that it allows you to actually see the interference and signal levels for each band, so in new locations it is a good idea to sit there for a couple of minutes and watch each channel to see how stable each signal is. Really the only time you would want to select one over the other is if you notice consistently bad signal in one range. OR if you are (for example) miles out in the country / middle of nowhere and you KNOW there won't be any other wifi around then you might set it to 2.4GHz only. Probably not worth the effort tho - Dual band is very good at doing the right thing.

Spot on explanation! I would stick to dual band. I thought of the 2.4 band only thing for a second too BUT as you say its gonna stay there unless it gets a lot of interference- so best just to leave it in Dual.

Thanks for the explanation Aero very useful for othrr noobs like myself who will no doubt wonder.

Yes, walls and trees are bad but especially troublesome is meat. Avoid passing your signal through large quantities of meat.












Like large crowds of people.

So stay away from fields full of cows.

Yeah, them too

Does anybody know the amount of penetration of 2.4 compared with 5.8? The former frequency is roughly half the former frequency, but I presume we don't have a linear relation here, so the penetration of 2.4 would not be simply twice that of 5.8.

The numbers are just that and nothing more 5.8 is not newer or better it is simply a frequency . Basically - 2.4 provides better coverage while 5.8 provides better and faster transmission feeds.

The real issue is water, not meat. It is the water in the meat. Water in leaves and plants interferes with most radio frequencies, reducing their strength between the transmitter and drone.

Listen. Let's just get this down to brass tacks.

You can't have any pudding 'till you eat ya meat.

How can you have any pudding if you don't eat your meat?

There.
