@Pebbleheed I am certainly not insulted by your actual experiences with the Spark, or the quite reasonable inferences you're making for the Mavic Air.
Having had direct, quite different experience with the Air, similar to my experiences with the Spark I'll add, it seemed some balance was appropriate regarding your assertions.
I didn't, and still don't question what you actually experienced, in the city and out in the countryside. I simply pointed out that where you were becomes irrelevant when there is actual data -- i.e. the connection performance in flight -- available.
Your actual data, such as it is, says only one thing: You were stationed with the RC in either a noisy environment, or a shielded one (were you among trees?). There's no alternative (well, other than a defect, but I'm not including that for the purposes of this discussion).
For some reason, pointing this out has riled you.
Does Occusync perform better than Mavic Air wifi? Yes. Substantially so.
Is the Mavic Air capable of meeting or exceeding the manufacturer's specified range? Yes, easily, as I've personally proven.
So, the issue isn't wifi, per se, but the environment one will be flying in that matters most. An urban environment? Not a good choice. Beachside community? Awesome.
