okay so this isnt really a question more just sharing what ive noticed because i see people arguing about this constantly and most of them havent actually flown both systems in real conditions. i fly a lot around an industrial park near me, theres a ton of machinery, some kind of radio equipment on the buildings, general RF mess. used to run a phantom 4 pro with Lightbridge for years and it was rock solid in there, occasional latency spike but never a full disconnect.

switched to a mavic 3 classic about 8 months ago with O3 and honestly the first month i thought i'd made a mistake. was getting these weird micro-dropouts, like the video would artifact and then clear up, happened maybe every couple minutes. not dangerous really but annoying and made me nervous. what i eventually figured out after a lot of testing is that O3 seems to recover faster when it does drop but it drops more often in heavy interference. Lightbridge felt more like it would degrade gracefully ? you'd see the quality go down before anything bad happened. O3 is more binary almost, fine fine fine then blip then fine again.

after the firmware updates over the past few months its gotten better, like noticeably. but i still think in genuinely nasty RF environments the older Lightbridge implementation had something going for it that people kind of dismiss now because O3 has better range in clean conditions. anyway just my two cents from actual flying not spec sheets.

this matches what a buddy of mine was saying about flying near a power substation. he had a inspire 1 for years and swore lightbridge was untouchable in bad conditions. got an inspire 3 and had to completely rethink where he positions himself relative to interference sources. i think dji optimized O3 heavily for the typical consumer use case which is open sky suburban flying and the edge cases in industrial or high-RF areas just werent the priority. not a criticism really just how product development works.

idk man i fly my mavic 3 near a marina with a ton of VHF marine radios going and its been totally fine. different kind of interference i guess but O3 hasn't given me any real trouble. maybe the industrial stuff you're dealing with is hitting specific frequencies harder. have you tried logging the signal data and looking at which band its preferring when it drops? might tell you something about whats actually causing it
