FCC Consultation on 42 GHz Spectrum Sharing
The Federal Communications Commission (FCC) in the United States has initiated a consultation process to explore the possibility of sharing 500 MHz of spectrum in the 42 GHz band. The primary objective of this effort is to optimize the use of this spectrum, with a particular focus on enabling small wireless service providers to leverage this resource.
For nearly a decade, the FCC has been studying frequency bands above 24 GHz for the provision of mobile services. The current interest is centered around the range between 42 GHz and 42.5 GHz, which is largely underutilized. The proposed idea is to encourage experimentation and collaboration with innovative initiatives in this spectrum. The intention is to make this spectrum usage non-exclusive, as it is relatively unclaimed, particularly in the United States, making it ideal for experimentation purposes.
The Notice of Proposed Rulemaking (NPRM) suggests licensing the 42 GHz band as five channels, each with a width of 100 MHz. The FCC is seeking feedback on various aspects of the shared license, including coordination mechanisms, development requirements, technical rules, and potential synergies with other sharing approaches. Similar approaches are already being considered for the lower 37 GHz band. Furthermore, the NPRM acknowledges the need to protect the 42.5-33.5 GHz band, dedicated to radio astronomy services, to avoid interference.
This initiative by the FCC demonstrates a proactive approach to optimizing spectrum usage and promoting innovation in the telecommunications industry. By opening up the 42 GHz band for experimentation and sharing, it provides opportunities for small providers and promotes collaboration among stakeholders. The consultation process will help shape the rules and regulations governing the shared use of this spectrum, ensuring its efficient and effective utilization while protecting important services in adjacent bands.
