Latta, Matsui Press Biden Administration on Lower 3 GHz Study Plans

House Communications Subcommittee Chairman Bob Latta, R-Ohio, and ranking member Doris Matsui, D-Calif., asked DOD and NTIA Wednesday for an explanation of how they will conduct new studies of the 3.1-3.45 GHz band, which the Biden administration's national spectrum strategy requires (see 2311130048). Both lawmakers strongly supported the House Commerce Committee-cleared Spectrum Auction Reauthorization Act (HR-3565), which proposes selling part of the lower 3 GHz band (see 2305240069). Lawmakers are grappling with reshaping a spectrum legislative package amid stalled talks and the DOD's negative findings last year about the effect that potential 5G use of the lower 3 GHz band would have on incumbent military systems (see 2312280044). The DOD “assessment found that non-federal operations are feasible if certain advanced interference mitigation features and a coordination framework are put in place,” Latta and Matsui said in a letter to NTIA Administrator Alan Davidson and DOD Chief Information Officer John Sherman. The national spectrum strategy's lower 3 GHz mandate provides an “opportunity to build upon” DOD's earlier findings by “studying additional private-sector access” on the band. “Clearly articulating the processes your agencies will use to study this band will help provide certainty for both federal and non-federal users,” the lawmakers said. They emphasized that NTIA developed the strategy “consistent with its statutory role as the sole agency responsible for authorizing Federal spectrum use.” They want insight from Davidson and Sherman about how DOD and NTIA will “co-lead” work on the new studies and “ensure a consistent and evidence-based process is used to establish methodology, assumptions, and parameters.” The legislators also want details about steps the agencies will “take to ensure all opportunities for commercial use in the Lower 3 GHz are fully considered and all relevant stakeholders have the ability to participate.”
