(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 wireless environment will bring, then

key insights

Protocols (such as Wifi and Bluetooth) will be radio applets by about 2020.

if an application needs more bandwidth, it can ask its radio to find capacity in unused spectrum.

an important problem is how to ensure radios do not use spectrum inappropriately (such as to interfere with public-safety channels).
