Part 90 Signal Booster Authorization: What You Need to Know
A pivotal moment is upon us for public safety communications. The Federal Communications Commission (FCC) has issued a public notice, inviting comments on a petition from the Safer Buildings Coalition (SBC). This petition proposes significant updates to the rules governing Part 90 industrial signal boosters, which are essential for ensuring reliable in-building communications for first responders. MCA supports this initiative, recognizing its potential to create safer communities through stronger, more reliable networks.
This is a rare opportunity to influence the regulatory landscape for the next decade. The last major update to these rules was in 2013, and the changes made now will have a lasting impact. At MCA, we believe that when we collaborate to elevate standards, we are all better together. This proceeding is a chance for all stakeholders—from public safety agencies to building owners—to contribute to a framework that ensures the integrity of our critical communication systems.
The SBC Petition: A Call for a Clearer Framework
The SBC has formally requested that the FCC amend section 47 CFR § 90.219 to establish a structured authorization framework for Part 90 signal boosters. These devices are crucial for eliminating “wireless dead zones” inside buildings and tunnels, where public safety radio signals can be blocked.
The Problem: Gaps in the Current Rules
The SBC’s petition highlights that the current regulatory framework, established in 2013, has significant implementation gaps. While the rules require signal booster operators to obtain “express consent” from the frequency licensee, they offer no specific guidelines on how this consent should be requested, granted, or tracked.
This lack of a standardized process has led to several critical issues:
- Improper Deployments: Poorly designed or installed signal booster systems are causing harmful interference to public safety radio networks.
- Lack of Competency: The absence of clear standards means system installers and designers may not be following FCC rules or may lack the necessary RF design and installation skills.
- System Integrity Risks: These issues directly impact the safety of first responders and the public by compromising the reliability of critical communication networks.
The Proposed Solution: A Structured Approach
To address these challenges, the SBC proposes a series of rule changes designed to create a clear and consistent process for all stakeholders. The goal is to reinforce the authority of frequency licensees while reducing administrative burdens.
Key proposals include:
- Structured Authorization Framework: Establish clear procedures for requesting, evaluating, granting, and tracking rebroadcast consent. This would be modeled on proven frequency coordination precedents.
- Mandatory Registration: Require operators to register both Class A (narrowband) and Class B (broadband) signal boosters in a Commission-managed database. Currently, only Class B boosters require registration.
- Updated Labeling Requirements: Modify the manufacturer labeling requirements for Part 90 signal booster devices to ensure clarity and compliance.
By implementing these changes, the SBC believes the FCC can proactively address coordination failures, reduce the need for reactive enforcement, and leverage market-based solutions to improve public safety communications.
The FCC Seeks Your Input
In response to the SBC’s petition, the FCC has issued Public Notice DA 25-853, officially seeking public comment on the proposed rule changes. The Commission is looking for input from all interested parties to determine the best path forward. Your insights will directly shape the future of signal booster deployment across the nation.
The FCC is specifically asking for comments on three critical areas:
- Problem Validation: Do you agree that improperly deployed signal boosters cause interference with public safety communications? Is this problem as pervasive as the SBC claims?
- Solution Effectiveness: Do you believe the SBC’s proposed revisions to section 90.219 will effectively address the interference issues?
- Alternative Solutions: Are there other solutions the FCC should consider? For instance, should the rules mandate that Part 90 signal boosters include a self-monitoring capability to automatically shut down if installed improperly, similar to rules for consumer signal boosters?
The deadline for submitting initial comments is October 16, 2025, and reply comments are due by October 31, 2025.
MCA’s Support: Building a Better, Safer Future Together
MCA strongly supports the SBC’s petition for rulemaking. We believe that establishing a standardized, comprehensive framework for Part 90 signal boosters is a vital step toward enhancing the reliability of our nation’s critical communications infrastructure. This initiative aligns with our core mission to seamlessly integrate voice, data, and security, creating solutions that empower our customers and protect our communities.
Our experience working with public safety agencies and enterprise customers across the country has shown us the direct benefits of a well-defined process. A standardized approach not only improves safety but also creates efficiency for everyone involved.
Our Recommendations for a Stronger Framework
MCA recommends the FCC establish a standardized practice for obtaining consent that addresses four key points:
- Establish Minimum Qualifications: Requiring qualified personnel to design, install, and maintain these systems is paramount. Certifications like the NICET In-Building Public Safety credential ensure that individuals have the expertise to prevent issues like interference and oscillation. This focus on quality produces a more resilient network, better equipped to support first responders.
- Define a Standardized Process: A uniform process for authorization would eliminate confusion and delays. By standardizing the criteria, required information, and processing times, third-party ERCES integrators can move projects forward efficiently, increasing deployment speed and reducing deployment issues. The current environment, with varying requirements across jurisdictions, creates unnecessary complications.
- Establish a Recordable, Searchable Format: A central database for registering signal boosters is a powerful tool. It would allow frequency licensees and the FCC to quickly identify and contact responsible parties to mitigate any noise or interference. This visibility is critical for maintaining network health.
- Create a Standard for Reauthorization: The database could also streamline reauthorization and testing requirements. A historical record of these activities would offer valuable insights into long-term network performance and the impact of signal boosters on overall network health.
For a real-world example of a successful model, we point to the process used by South Carolina to manage its Palmetto 800 statewide system. Their open dashboard provides all stakeholders with access to critical signal booster information, streamlining deployments and minimizing the potential for incorrect installations. Adopting a similar national standard would safeguard critical communication networks and improve public safety for all.
The Time to Act is Now
This rulemaking proceeding is more than a regulatory update; it is a foundational moment for the future of public safety communications. The decisions made will affect the reliability of life-saving networks for years to come.
Your participation is crucial. Whether you are a public safety official, a building owner, a system integrator, or a manufacturer, your expertise and experience are invaluable to this process. By submitting comments, you can help the FCC craft a framework that balances innovation with safety, ensuring that our first responders have the reliable communications they need to protect our communities.
At MCA, we are committed to being better together. We encourage all stakeholders to join this conversation and help build a stronger, safer, and more connected future.
