Although the basic approach appears to be simple, devel- oping a comprehensive solution in which devices rely on the geo-location service to determine white spaces availability is non-trivial. This is because our design introduces some unique challenges that must be overcome. A key issue in a network such as SenseLess is that it must continue to afford the same protection to incumbents as spectrum sensing would. This challenge coupled with all WSDs having to rely on a database to discover white spaces is a significant departure from conventional network designs. Hence, architecting such a network raises the following chal- lenges: TV detection: Relying solely on a geo-location service to detect TVs may result.
