A seismic shift in radio design could break the spectrum-availability
bottleneck, proponents say, and open up a new frontier of opportunities for
radio designers and wireless application developers. Cognitive radio one
that can sense its environment and location and then alter its power,
frequency, modulation and other parameters so as to dynamically reuse
available spectrum is emerging, but some are already calling it the holy
grail of wireless design....
High bands or low?

Though cognitive radio opens up possibilities for spectrum reuse, from 300
MHz at the low end right up to 100 GHz at the high end, opinions vary as to
the optimum path. Intel, Microsoft and others are excited about the lower
bands, where they could take advantage of TV spectrum to reuse "white"
space for data services while also creating an interactive TV experience
for mobile users. But broadcasters are loath to share their spectrum, and
at least one researcher points to the higher bands as a way around their
objections....
