Dominic Jainy stands at the intersection of emerging technology and critical infrastructure, bringing a wealth of experience from the worlds of artificial intelligence and blockchain to the complex arena of wireless spectrum policy. As an IT professional who has spent years observing how connectivity fuels industrial growth, he possesses a unique perspective on the delicate balance required to manage our nation’s airwaves. In our discussion today, we explore the intensifying debate over the 902–928 MHz band, a slice of spectrum that has quietly become the backbone of the American Internet of Things. We examine the tension between a new proposal for terrestrial navigation systems and the existing multi-billion dollar ecosystem that powers everything from smart utility grids to home security.
The 902–928 MHz band is often described as a workhorse of the American economy, yet many consumers may not realize how much they rely on it daily. Could you elaborate on the specific industries and infrastructure that would be most affected if this spectrum were significantly reconfigured?
This particular band is truly the unseen foundation for a massive portion of our modern digital life, acting as a shared space where hundreds of millions of devices coexist. When we talk about the 902–928 MHz range, we are looking at the lifeblood of smart utility meters that manage our energy consumption and the home security sensors that protect one in four American households through Z-Wave technology. It is not just about consumer gadgets, though; it is about the supply chain efficiency driven by RFID tags and the expansive LoRaWAN networks that connect our farms, factories, and even military installations. The scale is staggering when you consider that the LoRa Alliance alone anticipates their deployments to grow into the hundreds of millions by 2029. If we disrupt this ecosystem, we aren’t just losing a few signals—we are potentially jeopardizing the reliability of critical infrastructure that the U.S. economy depends on every single day.
There is a significant proposal on the table regarding a 15 MHz nationwide license for a terrestrial 5G-based Positioning, Navigation, and Timing network. How do you view the trade-off between achieving GPS resilience and maintaining the current unlicensed ecosystem?
Strengthening our national GPS resilience is undeniably a legitimate priority, as satellite-based systems are vulnerable and we need credible terrestrial backups for national security. However, the proposal to carve out a 15 MHz license in the lower 900 MHz band introduces a high-power 5G operation into a space specifically designed for low-power, cooperative coexistence. The risk here is that in the pursuit of a backup system, we might inadvertently dismantle a working environment that already delivers tens of billions of dollars in economic value. It is essential to ask whether we can achieve the goal of Positioning, Navigation, and Timing (PNT) without causing the stranded investment and operational chaos that a major reconfiguration would entail. We should be looking for a path that enhances our security without forcing a choice between a resilient GPS and the existing IoT innovation that has flourished under the current rules.
The financial implications for industries currently using this band appear quite severe, with some estimates reaching into the hundreds of billions. What does the economic data tell us about the potential cost of relocating or replacing these existing technologies?
The numbers provided by industry stakeholders are quite sobering and reflect the deep integration of these technologies into our society. For instance, the Edison Electric Institute has estimated that replacing the affected smart utility meters would cost ratepayers more than $100 billion, which is a massive burden to place on the general public. In the retail and logistics sectors, the RFID coalition suggests that replacing their infrastructure could result in an economic hit of $5.0 to $7.2 billion due to interference and equipment incompatibility. Beyond the direct costs, we have to consider the billions of dollars tied up in Z-Wave home security systems and industrial sensors that might become obsolete or unreliable. This isn’t just a theoretical loss; it represents real, deployed infrastructure that was built under stable spectrum rules that companies and consumers trusted.
Technical analysis has emerged suggesting that the coexistence between new 5G operations and existing Part 15 devices might not be as seamless as originally claimed. What are the specific technical red flags that have caught your attention in the engineering reports?
One of the most concerning aspects of the current proposal is the discrepancy in interference modeling, particularly the findings from a study commissioned by the RAIN Alliance. They pointed out that the original filing only examined two out of eight relevant interference scenarios, which suggests a significant gap in our understanding of how these signals will actually interact in the real world. Furthermore, independent analysts from groups like Public Knowledge have raised questions about spectrum efficiency, noting that the proposed PNT mission might only require 5% of the 15 MHz of spectrum being requested. This suggests a mismatch between the technical needs of a GPS backup and the sheer volume of spectrum that would be pulled away from the unlicensed community. When you have high-power 5G signals entering a band built for low-power harmony, the potential for “noise” to drown out critical data from utility sensors or medical devices is a risk we cannot ignore.
The level of opposition to this spectrum reconfiguration seems unusually high, involving thousands of parties and even bipartisan action in Congress. Why has this particular regulatory proceeding unified such a broad spectrum of stakeholders?
The pushback is extraordinary because the 900 MHz band is one of the few pieces of spectrum that has never been captured by a single interest, allowing a diverse range of innovators to thrive. When nearly 2,000 parties, including the U.S. Chamber of Commerce, healthcare providers, and public safety advocates, all file comments in opposition, it sends a clear signal to the FCC that the stakes are universal. We saw this concern reach a boiling point in April 2026 when the House Appropriations Committee moved to prohibit the use of funds for reconfiguring this band, followed by a House subcommittee hearing on June 4, 2026. This bipartisan alignment reflects a deep-seated worry that a hasty decision could compromise constituent safety and disrupt the utility networks that keep our cities running. It shows that Washington is listening to the technical and economic realities presented by the industries that actually use the airwaves.
What is your forecast for the future of the 900 MHz band and the quest for GPS alternatives?
I believe we will see a shift toward more surgical and less disruptive solutions for GPS resilience, such as utilizing the 800 MHz cellular band which already supports 3GPP-standardized technologies. By lifting outdated airborne or operational restrictions in those existing bands, we could actually accelerate the deployment of terrestrial PNT services much faster than we could by trying to re-engineer the 900 MHz band from scratch. The FCC’s broader Notice of Inquiry is the right move because it allows for a rigorous validation of all viable options, including various space-based and terrestrial solutions suggested by the NTIA. Ultimately, the 900 MHz band will likely remain a vibrant hub for unlicensed innovation, as the overwhelming evidence suggests that protecting this ecosystem is far more valuable to the nation’s long-term economic health than granting a restrictive license that threatens to strand billions in infrastructure.
