You’re clearly a person in search of using a tired overused expression.
5G
does solve problems we all have: available data bandwidth, speed and battery efficiency.
With the huge increase in bandwidth availability, 5G has the potential to replace WiFi. We’ll be able to use mobile data exclusively and it’ll show up built into everything from cars to laptops, from dog collars to TVs. It’s so much faster than LTE which is speed we’ll need for future applications like augmented reality. It’s designed to use very little power because 5G cell broadcasters will be everywhere, not just large far away towers.
So yes, it solves problems that we
do have.
