Radio communications: components, systems and networks [guest editorial]

Radio communications and networks continue to be one of the most exciting areas of science, technology, and business. Innovations continue to provide society with capabilities we could not have dreamed possible just a decade or two ago. The news is replete with examples of the application of new wireless technology, from entertainment (e.g., video clips and games) to unexpected uses such as messages to supporters from political candidates on the campaign trail. Novel technology, enlightened wireless and telecommunication policies, and exciting (and profitable) applications can be expected to continue in a cycle that is highly beneficial to society. In this issue we offer some further ideas that we hope will continue to support this cycle.
