Market-based Search offers all the functionality of ULS Advanced Search but conveniently narrows your search to just market-based licenses. Also, the new market-based search allows you to search for Cellular licenses and cellular market areas (CMAs).

The Buildout Deadline Search identifies wireless licenses that have a construction or coverage requirement, at the license, location, or frequency level, within the specified time frame. For all buildout deadline searches, the user must select an option under the Buildout Deadline Date as presented under the Date Information section. The search can be further refined by selecting an option under Deadline Information, also in the Date Information section, or by using fields found in other ULS searches such as FRN, Licensee Name, Radio Service Group, Radio Service Code, and Auction ID.
