As policymakers work to promote a vibrant wireless marketplace for all Americans and small businesses, it will be increasingly important for our country to adopt policies ‘promoting economic opportunity and competition’ and ‘avoiding excessive concentration of licenses…’ as the Communications Act instructs.”
