This proceeding was initiated to revise some of the Commission's general part 1 rules governing competitive bidding for spectrum licenses to reflect changes in the marketplace, including the challenges faced by new entrants, as well as to advance the statutory directive to ensure that small businesses, rural telephone companies, and businesses owned by members of minority groups and women are given the opportunity to participate in the provision of spectrum-based services. In July 2015, the Commission revised its competitive bidding rules, specifically adopting revised requirements for eligibility for bidding credits, a new rural service provider bidding credit, a prohibition on joint bidding agreements and other changes.
