Agreed. 5G is already in teh rearview mirror and since these types of technologies don't seem to be easily forward compatible, time to think about 6G. You probably won't have your best implementation unless you work with the mobile phone carriers (the article mentioned T-Mobile) but they don't seem to be taking this seriously. It's not possible to put a lot of time, effort, and money into this when you can't be sure it will ever become viable. FAA has plans for some sort of BVLOS implementation but it likely won't be available to many. And who know where this will land or how long it will be available. Too much risk. Until then, no one can take this seriously and development wouldn't go any further than beyond acknowledging the basics. There are so many things to do with a drone I wouldn't spend any extra developing the 6G capabilities. None of the US carriers will openly work with DJI at this point so my guess is, maybe 7G?
