## Abstract

The Commission concludes that licensing the 39 GHz band by Economic Areas (EAs), rather than Basic Trading Areas (BTAs), will provide ample population coverage and allow licensees the flexibility to provide many different types of services. This action was taken upon the Commission's own motion after consideration of Rand McNally's copyright interest in BTAs and the possible delays that this might cause to the 39 GHz licensing process. The Commission also concludes that it is in the public interest to allow licensees to partition along any licensee-defined service area. This action was taken in response to a petition for reconsideration of the Commission's earlier action in this proceeding allowing partitioning according to county boundaries or geo-political subdivisions. Finally, the Commission decides to exempt 39 GHz licensees from a build-out requirement of mandatory operation with 18 months from the initial date of grant. This action was taken because there is a new performance requirement of a substantial service showing for 39 GHz licensees. These amended rules will provide 39 GHz licensees with more flexibility in the use of their licenses.
