Martin Cooper

So the technology is becoming real, and at some point, those problems are going to get solved.

Is Cooper's Law named after you?

No, I didn't name it Cooper's Law.

I called it the law of spectrum capacity.

The amount of

bits of data that you can put at a given amount of radio spectrum.

People were nice enough to call that Cooper's Law, but it's not a law, it's an observation.

But that's been happening since radio was invented, since Marconi did the first commercialization of radio around 1900.

The capacity of the spectrum, the number of conversations that you could hold in all of the radio spectrum has doubled every 30 months.

And if you work the arithmetic, we have a trillion times the capacity today than Marconi had back in 1900.

And that capacity is going to keep increasing.

Well, it's kind of interesting, but much as I was not crazy about Steve Jobs as a person, Steve Jobs figured out the issue of the interface.

How do you connect advanced technology to a human being?

And he did work out this thing about the interface that we experience today with cell phones, using icons, using things that are intuitive.

And that was a game changer.

People had had...

cell phones before that that did have screens on them.

They never got it right.

I think that was a breakthrough.

The other breakthrough was in batteries.
