Licensing Requirements vs. License-Free Options for Security Radio
An analysis of when a security company needs an FCC license and when license-free (FRS/MURS) radios are sufficient for a security radio setup.
When planning a communication system for security teams, one of the most important decisions is whether to use FCC-licensed radio systems or license-free options. Both approaches have advantages and limitations — and understanding the regulatory requirements ensures compliance, optimal coverage, and reliable communication in daily operations and emergency situations.
Below we break down key regulatory differences and help you determine which option is right for your security operation.
📡 License-Free Radio Options — Easy Start, Lower Cost
License-free radios are attractive because they don’t require a formal FCC license and can be deployed quickly with minimal administrative overhead. In the United States, the most common license-free services include:
• Family Radio Service (FRS)
- Operates around 462–467 MHz in the UHF band.
- No FCC license required.
- Radios must be FCC-certified for FRS use.
- Low power limits and fixed antennas reduce range and interference risk.
- Ideal for short-range communication on small sites or indoor environments.
• Multi-Use Radio Service (MURS)
- Uses specific VHF frequencies around 151–154 MHz.
- Like FRS, no individual FCC license is needed.
- Offers slightly better propagation through obstacles (e.g., buildings) and allows external antennas for modest range gains.
- Limited channel selection and power (max ~2 W) still constrain coverage
Good Use Cases for License-Free Radios
✔ Small-to-medium facilities such as retail stores, schools, offices
✔ Indoor coordination tasks (security checkpoints, receptions)
✔ Temporary events where simplicity and quick setup are priorities
Limitations
⚠ Restricted power = shorter range
⚠ Shared frequencies = potential interference from other users
⚠ No private frequency assignment = less control in crowded RF environments
License-free radios are best for basic operational communication where coverage demands are limited and compliance simplicity is valued.
📡 When You Need an FCC License
For many professional security deployments, license-free options may not provide the range, interference protection, or frequency control required — especially in larger facilities or across multi-site operations.
• Business / Industrial Radio Licenses (Part 90)
Licensed radio systems — governed under FCC Part 90 — allow for:
- Assigned frequencies dedicated to your organization
- Higher power and broader coverage (indoors and outdoors)
- Custom frequency planning to avoid interference
- Options to use repeaters for extended range
An FCC license ensures that your communication channels are legally protected and privately coordinated, which is particularly important when radio reliability impacts safety and operational effectiveness.
Typical Scenarios Requiring Licensing:
✔ Enterprise-wide security networks spanning buildings or campuses
✔ Operations needing large outdoor range or repeater networks
✔ Environments with significant RF congestion (urban, stadiums, malls)
🧭 GMRS — An Intermediate Licensed Service (Not Ideal for Most Security)
While not typically used by security companies, the General Mobile Radio Service (GMRS) exists in the UHF band and does require an FCC license, usually obtained by individuals or families.
- GMRS allows significantly higher power and repeaters than license-free services.
- However, GMRS licenses are tied to individuals and family members — not organizations — making it impractical for business security use.
Because of these constraints, GMRS is generally not recommended for commercial security operations.
📌 Choosing Between License-Free and Licensed Radios
Here’s a practical framework for decision-making:
Use License-Free Radios When:
✔ Your security team operates on a single floor or small property
✔ You need quick deployment with no administrative hurdles
✔ Range requirements are modest and interference risk is low
License-free solutions like FRS and MURS are cost-effective first steps but may fall short in larger or complex security environments.
Get an FCC License When:
✔ You need dedicated, interference-protected channels
✔ Coverage must span multiple structures, parking lots, or campuses
✔ You plan to use repeaters or higher-power radios
✔ Reliable, mission-critical communication matters (e.g., emergency response)
A Part 90 business license gives your security team a legal and performance advantage — vital when radio communication cannot fail.
⚖️ Compliance & Best Practices
Regardless of the path you choose:
- Always use FCC-certified equipment designed for the service (FRS, MURS, Part 90, etc.).
- Avoid modifying radios to operate outside their designated service — this can violate FCC rules.
- When in doubt, consult a communications specialist or licensing agent to ensure your setup meets FCC regulations and performance goals.
Understanding licensing requirements versus license-free options helps security professionals balance compliance, performance, and cost:
- FRS and MURS: Great for simple, short-range, license-free use.
- Licensed Part 90 systems: Ideal for enterprise security with wider coverage, repeaters, and protected frequencies.
- GMRS: Licensed but not well-suited for business security due to usage restrictions.
Choosing the right spectrum and licensing strategy ensures that your security radio network remains legal, reliable, and effective — even in challenging environments.
