On January 17, 2025, the Federal Communications Commission (FCC) introduced a Notice of Proposed Rulemaking (NPRM) aimed at modernizing spectrum regulations to support advanced air mobility (AAM) systems and other uncrewed aircraft systems (UAS). These updates seek to enhance safety, innovation, and connectivity in the evolving aviation sector by optimizing spectrum use for command and control, drone detection, and in-flight broadband.
Key Proposals for Spectrum Allocation and Regulation
The FCC’s NPRM outlines several major spectrum policy updates:
- 450 MHz Band for Aeronautical Command and Control
- The FCC proposes opening the 450 MHz band for aeronautical command and control operations, enabling more reliable communications for crewed and uncrewed aircraft.
- A nationwide license model is suggested to simplify access and encourage efficient use.
- The proposal includes flexible licensing and operational rules to support varied altitude operations while minimizing interference with adjacent services.
- Enhanced Drone Detection in the 24.45-24.65 GHz Band
- The FCC aims to expand radiolocation operations within this frequency range to improve drone tracking and airspace safety.
- These measures are crucial for protecting critical infrastructure, airports, and other sensitive areas from unauthorized drone activity.
- Modernizing In-Flight Connectivity in the 849-851 MHz and 894-896 MHz Bands
- The NPRM suggests revising existing rules for Commercial Aviation Air-Ground Systems to enhance onboard broadband services.
- Updates will allow for improved passenger connectivity and more efficient spectrum management in support of next-generation in-flight communication technologies.
Advancing Air Mobility and Public Safety
FCC Chairwoman Jessica Rosenworcel emphasized the potential benefits of these regulatory changes, noting that advanced air mobility technologies could transform transportation by making regional air mobility, cargo delivery, and urban air shuttle services more accessible and efficient.
In addition to commercial applications, these technologies have critical public safety uses, such as:
- Assisting first responders in search-and-rescue operations.
- Delivering medical supplies and emergency aid to hard-to-reach locations.
- Supporting disaster response efforts, such as infrastructure inspections following natural disasters.
Next Steps and Public Consultation
The public consultation period for this NPRM is open until February 16, 2025. The FCC encourages stakeholders, including aviation companies, telecom operators, and public safety organizations, to submit comments on the proposed regulations.
