Sharing

Future G networks will require more dynamic, agile support for the management of radio spectrum on a fine-grained basis. The radio access network (RAN) technologies necessary to enable Dynamic Spectrum Access (DSA) have progressed significantly over the past 20 years, but the challenges of realizing the potential for DSA requires the co-evolution of technologies, business models, and regulatory policy. This paper presents a multidisciplinary research effort to develop the building blocks needed to advance DSA.

Brendan Carr, newly minted chair of the Federal Communications Commission, has been plenty busy making his mark in the telecommunications regulatory landscape. Here's a look at the most notable events that have transpired during Carr's first 30 days—and what we can expect in the months to come:

It’s becoming clear that there is going to a never-ending battle over mid-band spectrum. In late 2024, AT&T asked the Federal Communications Commission to allow for full-power use of CBRS spectrum.

The Federal Communications Commission adopted new rules to expand very low power device operations across all 1,200 megahertz of the 6 GHz band alongside other unlicensed and Wi-Fi-enabled devices. This added flexibility in the 6 GHz band will bolster a growing eco-system of cutting-edge applications like wearable technologies and augmented and virtual reality, which will enhance learning opportunities, improve healthcare outcomes, and bring new entertainment experiences.

When AT&T first floated a proposal to move Citizens Broadband Radio Service (CBRS) from 3.5 GHz down to the lower 3 GHz band, it sounded like a joke to some of the folks who work with CBRS on a daily basis. Such a move would be highly disruptive to the CBRS industry, which includes users as diverse as airports running private networks, farmers using precision agriculture and broadband providers serving rural areas.

An evaluation of a co-equal sharing framework to allow Federal and non-Federal users to deploy systems in the 37.0-37.6 GHz (Lower 37 GHz) band. The scope of this report is limited to sharing between Federal and non-Federal operations. The report assumes that the Federal Communications Commission will establish site-based authorizations for non-Federal licensees, but the report does not attempt to address how the FCC will regulate sharing between and among non-Federal systems.

The Federal Communications Commission has voted to revise its satellite spectrum sharing rules to promote market entry, regulatory certainty, and spectrum efficiency. The Report and Order released on November 15th refines the FCC’s non-geostationary satellite orbit, fixed-satellite service (NGSO FSS) spectrum sharing regime that provides clarity regarding sharing between systems licensed in different processing rounds, granting primary spectrum access to systems approved earlier, while enabling new entrants to participate in an established, cooperative spectrum sharing structure.

In an increasingly congested wireless spectrum, conflict is both inevitable but often resolvable. Between commercial applications (e.g., terrestrial and non-terrestrial wireless communications, navigation, and telemetry), scientific activities (e.g., radio astronomy, polar research, earth observation), and other vital spectrum-dependent uses (e.g., air traffic control), competition for spectrum access will only increase with new and emerging applications and technologies.

When president-elect Trump is sworn in for his second term on January 20, 2025, his administration will take over wireless policy. What analysts say we should expect: 

The Federal Communications Commission (FCC) adopted new rules to bolster the Commission's coordinated nationwide approach to the 4.9 GHz spectrum band through a nationwide band manager framework. "To ensure that the 4.9 GHz band is put to more robust use nationwide in the near term—the 4.9 GHz Band Manager, once selected, will be eligible to apply for a nationwide overlay license and authorized to enter into a sharing agreement with the First Responder Network Authority (FirstNet).
