(such as finding the right mix of programmable hardware to support high-performance signal processing in radios) undermined by almost complete
neglect (such as how to describe radio
behavior independent of platform
and how best to share spectrum). The
research, funding, and public-policy
communities have hard work to do if
they are to realize the promise of wireless data communications.
Here, I sketch the technology path
wireless data communications is on,
as well as the opportunities the future

will be radio applets by about 2020.
if an application needs more bandwidth,
it can ask its radio to find capacity in
an important problem is how to
ensure radios do not use spectrum
inappropriately (such as to interfere
with public-safety channels).
