Vestberg of Verizon: "2G to 3G, probably 10x better to handle data and 3G to 4G 10x at least. And minimum, I would say, 4G to 5G is the same."
"Will we be able to keep up with wireless growth?" I asked Hans Vestberg back when D.C. was screaming spectrum crisis. "Yes we will. I'm confident human ingenuity will deliver what we need," he replied. "That's always been true in wireless."
Years later, wireless speeds worldwide are much higher; congestion in the developed world remains an exception. Telcos continue spending $billions on advertising to find enough customers to fill their nets.
Without much more spectrum or many more cells, improved technology alone will cover likely demand until 2024 or 2026. (My calculation.) Putting to use currently fallow spectrum and modestly more density, wireless networks are good until 2030 or later.
