Exclusive licensing with an underlay is an appropriate paradigm for TV and other broadcast applications. Although further research is required on the viability of the more sophisticated forms of opportunistic access to insure the protection of TV signals, there are ways that a secondary device could safely use a broadcast band today. Thus, the FCC could move incrementally forward, allowing the underlay with sharing techniques that are known to be safe. This submission also suggests that the FCC consider certifying radio traffic signals as a viable approach. Underlay applications should also be reconsidered. We are more likely to see wireless last-mile connections than Wifi-like applications emerge in a broadcast underlay.
