25 Years Young

摘要

When I was a young man, the moment seemed like all there was, all there needed to be. Why plan? Why reflect? The days were just packed. Once I turned 25 - or somewhere around there - intimations dawning of my own mortality, I began to look both forward and back. It seemed like a good idea, perhaps even an important one, to draw from my own history, good and bad, and use that perspective to start building a more informed, more mapped-out future. That's what the Special Section accompanying this issue is all about. So much goes on at all times - the days are just packed - and we are so busy formulating solutions to the challenge of the moment, whether that be spoofing or indoor positioning or adjacent-band use, that we have little opportunity to reflect on how far we have come. To take the long view on just where we want to go in the next 25 years.
