Gigabit internet not good enough for 8 devices running 4K? Better check your connections. Thatís if you got 2 Netflix accounts(4 max simultaneously on one account). Netflix recommends 25mbs for 4K. Even if you doubled that and had 8 devices running 4K you still wouldnít come close to tapping out gigabit.
The space race for faster wireless service isnít needed on phones unless itís your primary source of internet. New technology usually rolls out in big cities where if isnít needed as much. They should roll it out in rural areas first.
