okay so ive been flying a relatively budget setup for about a year, using a mini 2 which runs ocusync 2.0 and honestly it's been pretty solid. but ive been looking at some of the newer wifi-based systems on mid range drones and reading really conflicting stuff. some people swear the newer enhanced wifi implementations are basically just as good now, others say as soon as you get around any kind of interference source its a disaster waiting to happen.

my use case is mostly urban and suburban stuff, not like downtown manhattan but definitely areas with a lot of wifi and bluetooth noise. i actually had a pretty sketchy moment last month where i was filming near a big outdoor event and the link got super choppy ? recovered fine but it rattled me a bit. im not sure if that was just bad luck or if it would've been worse on a wifi based system. would love to hear from people who have actually used both in those conditions rather than just spec sheet comparisons

genuine ocusync (the real dedicated RF link stuff) vs enhanced wifi is not even close in my experience when conditions get bad. i ran a skydio 2 for a while alongside my phantom 4 pro and the skydio's wifi link was noticeably more sensitive to interference in busy areas. not unusable, but you could feel it. the dedicated spread spectrum approach just handles congestion differently, it's not just marketing.

that said the newer stuff from DJI that they're calling o3 and o4 is doing some genuinely clever things with channel hopping and signal processing that closes the gap a lot. if you're talking about something running actual o3 then the comparison is different than if its a drone running basic enhanced wifi. what specific drone were you looking at because that actually matters a lot here

honestly i think people overstate this a bit? ive flown my mini 3 pro at outdoor festivals and farmers markets and stuff and never had a serious issue. choppy video sometimes sure but the control link stayed solid. maybe i've just been lucky but i feel like as long as you're not trying to fly through an actual server room the modern systems handle it okay. your event thing sounds like it mighta just been a bad spot with a bunch of people running hotspots all at once
