It is true that 5G will change everything?
"It is true that 5G will change everything... kind of. Samsung gave some examples: download a 15GB movie in six seconds on mobile broadband, 1.7Gbps broadband on a train travelling at 100kmph, 1ms latency enabling a self-driving car to stop in time to avoid a collision."
No, those are PR. Outside of a femtocell cell in an open plan office, cafe or hotel lobby (WiFi replacement rather than most regular Mobile) it's fantasy unless every other lamp post is a basestation.
