You know all those conspiracy theories about 5G? Well - looking at it from another perspective it seems to be the case that (1) the vast majority of the facebook-scrolling population will never see any difference in speed because 4G is already much faster than what they can consume, (2) it seems to be rammed down our throats even though nobody asked for it (3) industry keeps saying it's going to be super important for business.... without ever presenting even a single actual business case, certainly not one that would somehow ROI 100s of billions of dollars investment - compared to 4G.
I have heard 5G might make VR over wireless possible - but the applications of that are just dreams of startups, nothing that's either a given or proven to make money. It'll be cool but is it going to be a $100Bn business?? Probably not.
I've heard games will be awesome due to low lag. Sure they'll be - except you have WiFi which is just as good or better and the use cases for super low lag gaming on phones are edge cases.
And the list goes on. Fast internet is epic but it does not change the fact that 4G speeds are good enough for 99% of use cases ...the business metrics give credence to conspiracy theories. Namely, whatever the reasons are to put these antennas everywhere, they're not the reasons we've been told, because the reasons we've been told make no sense....
