No need to worry about 5G for a couple of years. The ch8nese company that makes most of the 5G equipment is meeting resistance on getting it imported. The industry should find another manufacturer.
So instead of Wi-Fi???
instead of getting internet from cable or fiber optic, 5G promise to deliver speeds 100x faster, over the air. will still take 5-10 years to become mainstream, but that's where the industry is heading.
yes, it will be nice over mobile, but the true benefit will be in home's and office's.
and that's why the wireless companies are jumping all over this.
