The dual-band USB wifi adapter has just dropped through my letterbox but, as I suspected, it certainly isn't a "plug & play" connection to Android - so unfortunately it fell at the first hurdle! For information, under the hood its a Realtek RTL8811AU 802.11ac USB 2.0 network adapter. The description on Amazon says it can be used with Android, and one user comment says he plugged it into an Android set-top box and it worked stratight away. However, I suspect he was getting confused between Linux and Android .....
But no matter - it was cheap, and it now adds 2.4 and 5GHz wi-fi connectivity to my desktop PC so I can at least do some experimentation and check what frequencies and channels the AC and RC are using. I rooted my Moto G3 phone the other day, so I'm going to see if there's a way to delve into the operating system to get it to see the adapter - but without an Android driver I suspect that's unlikely! I'm a Windows and .net/C# man, so Android is a big challenge for me!
Another idea occurred to me though having come across the Netgear 750AC EX6100 wifi extender, which supports "Fastlane" technology. To quote from the user manual - " with FastLane technology, the extender connects to your router using one band and connects to your devices using another band". So basically it will connect a 2.4GHz device to a 5GHz router ......
The first problem is that it's a mains powered device, designed to plug directly into a mains socket. So it would require mofification to use a powerbank to make it portable. Then I suspect there might be configuration issues with the Spark RC. But again, it's worth doing some ongoing research - starting with trying to find an alternative dual band extender with Fastlane support that can be powered via a 5v USB adapter.
It would all be so much easier if we knew for sure that DJI have definite plans to support OTG for connection to an Android phone. I've had my Spark for about a month, and haven't flown it yet. I'm therefore in no hurry, and am happy to wait several months if this is on DJI's development schedule - if only they'd let us all know one way or the other!
