Pursuant to a legislative requirement, GAO reviewed the Federal Communications Commission's (FCC) new rule on the geographic partitioning and spectrum disaggregation for the 220-222 megahertz (MHz) service. GAO noted that: (1) the rule would amend the FCC's rules to allow the holders of licenses in the 220-222 MHz band to partition their licensed geographic area and disaggregate their licensed spectrum; and (2) the FCC complied with the applicable requirements in promulgating the rule.
