Huh? If you mean over the air, as in radio/televison, I think the
gigabit capability is going to be a hard thing to do.

Little problem called the Shannon Capacity of a channel. To get a
gigabit over a real channel, one will need quite a bit of bandwidth
(as in hundreds of megahertz in a real system).

Now, if you deliver this by fiber optics, you could perhaps claim
it is wireless, but it is not wireless in the sense most people think
of it.


Wireless broadcasting like the IPTV that Qualcomm and Crown Castle will
introduce this year to cell phones will be ubiquitous at much higher
bandwidth in a few years and not limited to cell phones.

The Shannon Capacity of channels won't change.

See http://en.wikipedia.org/wiki/Shannon_capacity for more discussion.
