Vint Cerf, a ‘father of the internet’, still isn’t completely sold on 5G

A Q&A with Vint Cerf. 

First question, 5G as a broadband alternative for homes and businesses. You sounded a little down on that.

It’s only because I’m worried about 6 gigahertz versus 28 gigahertz. The studies that have been done from the DoD show the 28 gigahertz is very costly, still requires a great deal of fiber interconnect, and might put us in a poor competitive position with regard to serving the rest of the world.
