Abstract

No matter how hard we try, the tower of Babel will not go away. We continue to have multiple air link technologies, and dissimilar discontinuous spectrum. The only elegant near-term solution is the SDR approach, which promises to offer flexibility not achievable with hardware approaches.

The potential to reconfigure radio attributes offers great hope and promise in the commercial sector. Not only would it allow opportunities for ease of spectrum access through multi-mode/multi-band operation, but it can possibly enhance the user experience through variable preference selection.
