Sharing

Policymakers inundated with self-serving arguments for specific spectrum allocation need ways to evaluate which actually advance the public interest. By focusing on the goal of productive spectrum use, one can differentiate between reasoning that would enhance productivity and that which would only advance private interests.

Spectrum is vital to our most sensitive and important Federal missions, including military radar operations for homeland security, the training of our war fighters before they deploy overseas, and our ability to develop new and advanced military capabilities. Within this context, the Department of Defense has completed and submitted to the Department of Commerce the Emerging Mid-Band Radar Spectrum Sharing (EMBRSS) Feasibility Assessment as directed by the Infrastructure Investment and Jobs Act.

As new spectrum based services come online, the demand for spectrum has increased significantly. At the same time, greenfield spectrum to meet these needs is becoming more scarce, and clearing government and other incumbent users from currently-allocated spectrum has become more challenging.

Faster fixed wireless came a step closer because the Federal Communications Commission has approved testing of automated frequency coordination (AFC) systems for the 6 GHz band.

In 2022, a study commissioned by CTIA basically called Citizens Broadband Radio Service (CBRS) a failure, in part due to its low power levels and limited use cases. Some saw it as a smear campaign against CBRS because CTIA would prefer the 3.1-3.45 GHz band to be licensed rather than end up looking more like CBRS, which involves a three-tiered sharing system to protect Department of Defense (DoD) incumbents. Federated Wireless 

For decades, the Department of Defense (DoD) has had relatively unquestioned access to a large portion of the electromagnetic spectrum — a critical resource that enables capabilities like radars, satellite communications, and navigation systems. However, a number of leaders at the Pentagon are concerned that access may soon be taken away. There has been a years-long battle between the DoD and the commercial telecommunications industry over access to the 3.1-3.45 GHz S-band. That portion of spectrum has been solely designated to the DoD for decades.

The Federal Communications Commission circulated draft rules to govern the lower 42 GHz spectrum (between 42 – 42.5 GHz). This is within the range of spectrum referred to as millimeter wave spectrum. This is one of the more unusual FCC spectrum deliberations because this spectrum is totally empty – there is nobody currently authorized by the FCC to use the spectrum band.

One of the hardest things that the Federal Communications Commission does is to decide spectrum policy. The agency has full authority to determine the details of how we use each slice of available spectrum. Most importantly, the agency can determine who can use spectrum – and that’s why the task is challenging. In the last decade, it’s hard to think of any spectrum deliberation and decision that didn’t have to weigh the interests of multiple spectrum users. There is almost always somebody using spectrum that must be considered.

The Federal Communications Commission launched a proceeding to consider innovative sharing models in 500 megahertz of spectrum in the 42 GHz band. This examination of sharing models in high-band spectrum could not only inform how this band might best be used—particularly by smaller wireless service providers—but also inform future uses of sharing models in spectrum management. With ever-increasing demand for wireless services and a finite supply of airwaves, it is more important than ever to focus on finding ways to share spectrum, a valuable resource.

The US Department of State, on behalf of the US Government, has submitted a proposal to the May 2023 Inter-American Telecommunications Commission (CITEL), which calls for opening the 3300-3400 MHz band for 5G mobile services within the Americas Region. If accepted as a regional proposal, CITEL would submit to the November 2023 World Radiocommunications Conference (WRC-23). If adopted by the WRC-23, the international Radio Regulations would be updated to identify this band as possible for 5G use in the Americas by countries that choose to do so.
