Re: I dont really understand why i need 5g at all
Typical LTE struggles with dense crowds. Adding high-frequency 5G would allow for offloading some data transfers to very small and fast cells that don't saturate or interfere with each other. That said, there are only a few spots on Earth where LTE fails - pretty much just stadiums and big outdoor events. The transmitter upgrades will be cheap and effective because so few areas will need them. Selling premium phones with 5G is going the be the hard part.
I don't think the telcos are looking at eliminating LTE yet. It's hard to find good tech articles but it looks like 5G requires a 4x4 MIMO antenna - perhaps one that actually works in a hand. If so, that would be a manufacturing complexity that never goes away as the technology matures.
