5G- Please give your views/ideas/advice or any comment on the below post.

Will it be possible ? And what problems will come?

As 5G is gonna use millimeter waves, it gonna require many small towers for emission, it can be connected to the light poles on the streets and can be even shared and transmitted via mobile hotspot/Bluetooth.

I actually dont have too much idea...i have to give a presentation for a ideation in my college and gatering ideas and information....and thank you
