Re: It will have little effect on handset or modem sales.
Just you wait...
The Samsung Galaxy S8 already contains a modem capable of doing 1GB/sec transfers.
As far as we know at the moment, the iPhone 8 won't get more than 450MB/sec.
Guess who will plaster adverts extolling the higher speed all over the TV, Busses and media in general even though there are no networks outside of South Korea capable of using those speeds and won't be for at least 2-3 years.
People will buy into the S8/S9 because of the higher data rates but will be disappointed when they can't even get a decent 3G rate but Samsung(or whoever) won't care, they'll have the punters/suckers money.
Shiny-shiny-bling, my thing is bigger and better than your thing...
Naturally, no one here would fall into that trap now would they?....
