FCC License

Why FCC licensing matters for businesses

Licensing is about two things. First, it assigns your operation specific frequencies so you are not fighting constant interference. Second, it sets technical parameters that make you a good neighbor in the spectrum. The benefits are tangible.
  • Better audio quality because fewer outsiders are sharing your channel.
  • Predictable coverage because your equipment and antenna plan match licensed parameters.
  • Legal protection that allows you to report harmful interference on your assigned channels.
  • Lower risk. Unlicensed misuse can lead to fines, forced shutdowns, or equipment confiscation.

The main radio services businesses consider

The FCC defines several radio services. As a business owner, you will usually fall into one of the paths below. The point here is not to memorize rule parts, but to understand which path aligns with your use case.

Business and Industrial Pool – private, professional, licensed

  • Typical choice for hotels, warehouses, hospitals, campuses, construction, utilities, and field services.
  • Often called “Part 90” business or industrial licenses.
  • Lets you run higher power, outdoor and indoor repeaters, and external antennas for reliable site-wide or campus coverage.
  • Frequency coordination by a certified coordinator is usually required before filing. This helps select channels that fit your location and reduce conflicts.

License-free options – simple, short range, device-limited

  • Services like MURS and FRS use fixed technical limits and do not require a user license. They can be useful for very small teams, pop-up events, and short-range operations.
  • You give up dedicated channels, elevated antennas, and higher power. Coverage is limited and interference is more likely.
  • These services are best viewed as entry level or backup, not a replacement for a business license when reliability is mission critical.

Specialized wide-area services. Pay for footprint. Skip your own license.

  • Some vendors operate shared repeaters or “SMR” systems that provide wide-area coverage by subscription.
  • This can make sense if you need regional mobility without owning infrastructure. You operate under the provider’s license on their system.
  • You trade control for convenience. If you need private channels on your own property, a Part 90 license is still the gold standard.

A simple decision path you can follow

Use this sequence to quickly narrow your path.
  1. Define the work. Indoors only, mixed indoor and outdoor, or vehicles in the field.
  2. Decide if you need a repeater. If your site has dead zones or multiple buildings, plan for one.
  3. Choose band preference. UHF for buildings and campuses. VHF for wide open outdoor areas. If unsure, test both.
  4. Pick your service. For business-critical reliability and control, select the Business and Industrial Pool with coordination and a site license. For pop-up or very small footprint work where interference is acceptable, consider license-free options.
  5. Plan the timeline. Coordination and licensing add lead time. Build this into your project calendar.

What the license actually covers

When you apply for a business license, you specify a set of details. This is what defines your lawful operation.
  • The legal entity that holds the license. Use your correct business name and address.
  • Exact transmitter locations. For a building, this is the coordinates of the rooftop or mast. For a mobile-only fleet, you can license an area of operation.
  • Frequencies and bandwidth. These come from the coordinator’s recommendation and your equipment capabilities.
  • Emission designators. These define analog voice or digital voice and the channel spacing you will use.
  • Antenna details. Height above ground, gain, and pattern if applicable.
  • Power levels and service area. This helps define the interference footprint and keeps the system neighbor-friendly.
What a frequency coordinator does
For business and industrial pool channels, the FCC expects you to work with a certified coordinator before filing. Coordinators check who else is operating near your site, run contour studies, and recommend channels and power that deliver coverage without causing harmful interference. They also help select itinerant or on-site channels if mobility is important. Paying a coordinator up front saves headaches later because you start on the right channels.

Step-by-step: how to license your business radios

Follow these steps in order. They work for most business and industrial users.
FCC Part 90 Business Radio Licensing
FCC Part 90 Business Radio Licensing

Step 1. Capture your operational requirements

Write down who will talk to whom, where, and how often. Identify noisy areas that require headsets, stairwells and basements that challenge coverage, and any safety requirements like lone worker or man-down. Decide if you need encryption for incident traffic. This informs band choice and whether you need a repeater.

Step 2. Select equipment that fits your plan

Choose UHF or VHF models that support your intended technology. Analog remains common. Digital such as DMR adds talkgroups and capacity. Confirm that your chosen radios and repeaters meet current narrowband requirements and support your preferred accessories.

Step 3. Engage a frequency coordinator

Provide your site address, antenna height, building description, county or parish, and a short narrative of your use case. Ask for on-site channels optimized for your footprint and for any itinerant channels if you sometimes work off property. The coordinator will return a recommendation for frequencies and parameters tailored to your location.

Step 4. Create or update your FCC CORES account

You will file your application under your business’s FCC Registration Number. If you already have one, confirm that contact information is current. The FCC sends renewal and correspondence notices to the email and address on file.

Step 5. File the license application

Using the coordinator’s data, complete the license application in the FCC system. Double check legal name, responsible party, and contact information. Attach any letters from the coordinator as required. Save a copy of your application and confirmation for your records.

Step 6. Wait for grant and document the result

You will receive a call sign and an authority to operate once granted. Save the grant document in your compliance folder. Many businesses also print a copy for the communications binder alongside programming files and a quick reference channel map.

Step 7. Build and test your system

Once the license is granted, install the antenna, cabling, and repeater if used. Program radios to match the licensed parameters. Perform a coverage walk test that includes basements, stairwells, and far corners. Record any weak spots and address them by adjusting antenna height, moving the repeater location, or adding a distributed antenna solution if necessary.

Operating Responsibly

Licenses have a fixed term. Put the expiration date on your calendar with a renewal reminder well ahead of the deadline. Keep contact data current in CORES so renewal notices reach you. Review your system annually. If you relocate antennas or add repeaters, coordinate updates and file modifications so your paperwork matches reality.

1) Common pitfalls and how to avoid them

Buying radios first and discovering they do not fit your licensed channels. Always plan the license and channels first.
Assuming license-free radios will cover a large building. In practice, the fixed antennas and power limits make coverage unpredictable.
Letting programming drift. If your radios do not match the license parameters, you are out of compliance and may cause interference.
Ignoring the antenna plan. Antenna height and placement matter more than raw power for coverage and clean operation.
Missing the renewal window. Put two reminders on different calendars and verify your business email address in the FCC system.

2) Coverage, interference, and your responsibilities

A license grants you the right to operate under defined conditions, but it does not guarantee silence on the air. You are responsible for engineering a system that is both effective and neighbor-friendly.
Use the lowest power that achieves reliable coverage on your property.
Keep your occupied bandwidth tight by aligning deviation and using quality equipment.
Weatherproof and maintain connectors and feedline so they do not create intermod noise.
If you experience harmful interference on your licensed channel, document dates, times, and locations, then consult your coordinator or vendor for mitigation steps.

3) Security and privacy considerations

Analog voice is easy to receive with off-the-shelf scanners. If your traffic includes sensitive operations or patient or guest incidents, consider digital with encryption and manage keys with a written process. Licensing defines your frequencies and technical parameters. It does not secure your content. Security is a separate decision about technology and policy.

4) Multi-site, mobile, and itinerant operations

Many businesses split time between a primary property and temporary job sites.
Consider licensing both fixed on-site channels for your property and itinerant channels for pop-up work. Program them into your fleet with clear names so users switch correctly.
If you move around a metro area every week, a managed wide-area provider may be more efficient than multiple site licenses. You pay monthly and operate under the provider’s authority.
If your vehicles roam beyond your county, note this in the license application. The coordinator will account for your travel radius in frequency recommendations.

5) Budgeting time and cost

Expect time for coordination, filing, and grant. Plan your deployment date accordingly. Coordination and filing have fees. Equipment installation has labor costs. The license term is long enough that the investment spreads out well over time. Most businesses recover the cost quickly through fewer delays, fewer missed calls, and higher safety.

6) How licensing ties into your SOPs and training

Licensing is not simply paperwork. It defines how your radios must be programmed and used. Reflect the license details in your standard operating procedures.
Post a one-page channel plan with plain names and the intended use for each channel.
Train PTT technique, battery care, and when to use the site-wide or emergency channel.
Assign responsibility for the communications binder that includes the license grant, programming files, antenna drawings, and contact numbers for your vendor and coordinator.

7) Renewal, modifications, and ownership changes

Businesses evolve. When something material changes, update your records.
Moving to a new building. File a modification for the new site and work with the coordinator to re-evaluate channels and antenna height.
Changing legal name or ownership. Update CORES and the license contact info so future notices and renewal emails go to the right place.
Adding a second repeater or a new talk-in coverage area. Coordinate and file the modification before you go live.

FCC Licensing Timeline and Conditional Operation, Sources:

Licensing Timeline and Conditional Operation

Normal Timeline: Applications appear on FCC public notice; most uncontested filings are granted in 1–2 weeks.
Conditional Authority (10-Day Rule): Under 47 CFR § 90.159 you may begin operating 10 business days after submitting a fully coordinated application and may continue up to 180 days if:
  • The site is outside Canadian or Mexican border coordination zones.
  • No rule waivers are requested.
  • The antenna complies with FAA and environmental rules (law.cornell.edu
If the FCC dismisses or denies the filing, conditional authority ends immediately. For urgent deployments, an STA (Special Temporary Authority) can be requested

License Duration and Renewal

Part 90 licenses are valid for 10 years. Renewal may be filed up to 90 days prior to expiration. A 30-day grace period allows late filing, but transmit authority lapses until renewal is issued. New site-based systems must be constructed and on-air within 12 months, or the license cancels automatically

Legal Obligations and Penalties for Unlicensed Operation

FCC rule § 90.403(a) requires a valid license for any Part 90 transmission.
Fines start at $10 000 per day of unlicensed operation and can include equipment seizure (https://docs.fcc.gov/).

Frequency Sharing and Geographic Considerations

Part 90 channels are shared spectrum. Coordinators apply distance-separation or contour-overlap rules (docs.fcc.gov (https://docs.fcc.gov/)). Most Industrial/Business Pool frequencies are shared, and itinerant channels carry no interference protection (govinfo.gov (https://www.govinfo.gov/)). Terrain, urban density, and international borders (north of Line A) further influence channel reuse.

Preventing Interference: PSI’s On-the-Ground Spectrum Analysis

Database coordination is not fool-proof; Part 90 licensees must monitor channels to avoid harmful interference.
PSI performs field surveys and spectrum scans before ordering frequencies. These scans detect hidden interferers—e.g., a 100-watt transmitter one mile away on a “clear” channel—allowing PSI to choose alternate channels or adjust system parameters and ensure reliable communications from day one.

GMRS Considerations

Many small businesses buy GMRS radios without realizing they require an individual FCC license (Part 95), separate from Part 90. The article's "license-free" section implies FRS/MURS are the only options but GMRS is a common source of confusion and violations.

FCC Two-Way Radio License FAQ for Businesses

Top FCC licensing questions answered for business owners. Costs, timelines, GMRS vs Part 90, penalties, and more.

THE BASICS: DO YOU NEED A LICENSE?
Q01. Do I need an FCC license to use two-way radios for my business?
Answer - Most likely yes. Almost all UHF (400–512 MHz) and VHF (136–174 MHz) professional business radios require an FCC Part 90 Industrial/Business Pool license to operate legally in the United States.
The exceptions are license-free radio services: FRS (Family Radio Service, 2W max, fixed antenna), MURS (Multi-Use Radio Service, 5 VHF channels, 2W max), CB (Citizens Band, 40 channels, 4W), and 900 MHz ISM band radios like the Motorola DTR series. These are genuinely license-free but offer limited coverage, no dedicated frequencies, and no interference protection.
Industry estimates suggest that 80–90% of businesses using professional radios do not have an FCC license — which means they are operating illegally and are exposed to significant fines.

Source note: 47 CFR Part 90 · FCC Industrial/Business Pool Rules

Q02. What radios do NOT require an FCC license?
Answer - The following radio services do not require a user license to operate:
FRS (Family Radio Service) — 2W max, fixed antenna, no repeaters. Best for: consumer use, events, small teams.
MURS (Multi-Use Radio Service) — 2W max, 5 VHF channels, no repeaters. Best for: retail, warehouses, small sites.
CB (Citizens Band) — 4W AM, 40 channels, no repeaters. Best for: trucking, short-range.
900 MHz ISM Band — power varies, no repeaters. Best for: digital business use (e.g., Motorola DTR series).
Note: GMRS (General Mobile Radio Service) does require a license ($35, Part 95E), though it is sometimes mistaken for license-free. None of these services provide dedicated frequency assignments or FCC interference protection.
FRS, MURS, CB, License-Free
Q03. What is the difference between Part 90 and GMRS for businesses?
Answer - Part 90 (Industrial/Business Pool) is the correct license for professional commercial operations. It allows higher power, repeaters, external antennas, and site-specific frequency assignments with interference protection.
GMRS (General Mobile Radio Service, Part 95E) is a personal radio service designed for family and short-range use. It is not designed for high-powered commercial operations and does not provide the same level of spectrum protection.
Comparison:
Part 90 vs. GMRS:
- Purpose: Commercial operations vs. Personal/family use
- Max Power: Up to 100W (site dependent) vs. 50W (mobile)
- License Cost: $300–$800+ vs. $35
- Repeaters: Yes, licensed vs. Yes, shared
- Dedicated Frequencies: Yes, site-specific vs. No, shared pool
- Interference Protection: Yes, FCC enforced vs. Limited
- Reselling Airtime: Allowed (with SMR) vs. Not allowed
- License Term: 10 years vs. 10 years
The bottom line: GMRS is a low-cost option for simple coordination needs, but it is not designed for commercial operations where frequency exclusivity and system reliability are mission-critical. Businesses that depend on radio communication should use Part 90.
GMRS, Part 90, Part 95

Q04. What is the difference between UHF and VHF — and which needs a license?
Answer - Both UHF and VHF business radio bands require a Part 90 license for professional operation. Here is how to choose:
UHF (Ultra High Frequency, 400–512 MHz): Better for indoor environments. Shorter wavelengths penetrate concrete, steel, and building materials more effectively. Best for: hotels, hospitals, warehouses, construction sites, and urban campuses.
VHF (Very High Frequency, 136–174 MHz): Better for wide open outdoor coverage. Longer wavelengths travel farther over flat terrain. Best for: farms, golf courses, marinas, open construction sites, and parks.
If unsure, your frequency coordinator will evaluate your site and recommend the right band. Many businesses program both bands into their fleet.

CATEGORY 02 — COSTS & FEES
Q05. How much does an FCC business radio license cost?
Answer - There is no single flat fee — costs vary by service type and how much help you use. Here is a realistic breakdown:
FCC filing fee (Part 90): approximately $65 per application
Frequency coordinator fee: $100–$400+
Professional filing assistance: $200–$500 (optional)
Total Part 90 license: approximately $300–$800+
GMRS individual license: $35 (no coordinator needed)
The license covers unlimited radios on your licensed frequencies — you are not charged per device. Spread over a 10-year license term, this is a very low annual cost relative to the protection it provides.

Source note: 47 CFR § 1.1102 · FCC CORES fee schedule

Q06. How long is an FCC license valid?
Answer - Part 90 Industrial/Business licenses are valid for 10 years. GMRS licenses are also valid for 10 years. The license is not issued per device — it covers all radios operating under your licensed frequencies during that 10-year period.
The FCC sends renewal reminder notices to the contact email on file in your CORES account. You can file for renewal up to 90 days before expiration. If your license lapses without renewal, you must reapply as a new application — which restarts the full coordination process.
License Term, Renewal

Q07. What are the penalties for operating without an FCC license?
Answer - ⚠ CALLOUT — FCC Enforcement:
FCC fines for unlicensed radio operation start at $10,000 per violation and can reach $25,000–$100,000 for willful or repeat violations. Hotel and hospitality operators have received fines in the $25,000–$50,000 range for commercial unlicensed use.
Beyond monetary fines, the FCC can order equipment confiscation and operational shutdowns. Unlicensed operators also have no legal right to report interference — if another business is disrupting your communications, you have no recourse without a license.
The cost of a license ($300–$800 over 10 years) is always less than a single FCC fine. Compliance is the practical choice, not just the legal one.

CATEGORY 03 — HOW TO APPLY
Q08. How do I apply for an FCC Part 90 business radio license?
Answer - The standard Part 90 licensing process follows these steps:
Step 1 — Define requirements. Determine your coverage area, band (UHF or VHF), whether you need a repeater, and if encryption is required for sensitive traffic.
Step 2 — Engage a frequency coordinator. Provide your site address, antenna height, building description, and use case. The coordinator recommends channels and power levels that will not conflict with nearby licensees.
Step 3 — Create an FCC Registration Number (FRN). Register at apps.fcc.gov/cores under your correct legal business entity name and address.
Step 4 — File FCC Form 601 through the Universal Licensing System (ULS) at wireless.fcc.gov, using the coordinator's frequency data.
Step 5 — Pay the filing fee (~$65) when prompted. The application is not accepted until payment clears.
Step 6 — Receive call sign and license grant. Most uncontested applications are processed within 1–2 weeks after coordination is complete. Store the grant document in your compliance binder.
Tags: Form 601, ULS, CORES, Application Process

Q09. What is a frequency coordinator and do I need one?
Answer - A frequency coordinator is an FCC-certified private organization that recommends the most appropriate frequencies for your location before you file your application. For Part 90 new licenses and most major modifications, frequency coordination is required — not optional.
Coordinators search the FCC database for nearby licensees, run distance-separation and contour studies, and recommend channels and power levels that will achieve your coverage without causing harmful interference to others. Some perform on-site spectrum scans to detect unlisted interferers.
Well-known coordinators include the Enterprise Wireless Alliance (EWA), APCO International, and various regional organizations. Your radio dealer or vendor can often recommend one appropriate for your band and geography.
Tags: Frequency Coordination, EWA, APCO
Source note: 47 CFR § 90.175 — Frequency coordination requirements

Q10. Can I start operating before my license is granted?
Answer - Yes — under Conditional Authority (47 CFR § 90.159). You may begin operating 10 business days after submitting a fully coordinated application and may continue for up to 180 days while your application is pending, provided that:
- Your site is outside Canadian or Mexican border coordination zones.
- You are not requesting any rule waivers.
- Your antenna complies with FAA notification and environmental rules.
If the FCC dismisses or denies your application, conditional authority ends immediately. For truly urgent deployments — emergencies, short-duration events — a Special Temporary Authority (STA) can be filed using Form 601 for up to 180 days with a written justification.
Tags: Conditional Authority, STA, § 90.159

Q11. What are itinerant frequencies and can my business use them?
Answer - Itinerant frequencies are pre-designated channels in the Industrial/Business Pool that businesses can use when operating away from their primary licensed site — at a temporary job site, event, or new location not yet on their license.
Itinerant operations do not require site-specific coordination or a modification to your existing license. However, they carry no interference protection — anyone else using the same itinerant channel has equal right to it. They are best used as a supplement to on-site licensed channels, not a replacement.
Many businesses program itinerant channels alongside their licensed site channels in their radio fleet, with clear labeling so users know which channel to use and when.
Tags: Itinerant, Temporary Sites, Mobile Operations

Q12. Do repeaters need their own FCC license?
Answer - Yes. A repeater is a fixed base station and must be explicitly licensed. When you apply for your Part 90 license, you specify the repeater's location coordinates, antenna height, effective radiated power (ERP), and operating frequencies as part of the application.
If you add a repeater after your initial license is granted, you must file a major modification and complete new frequency coordination before the repeater goes live. Operating an unlicensed repeater carries the same penalty exposure as any other unlicensed operation.
Tags: Repeater, Base Station, Infrastructure

CATEGORY 04 — OPERATIONS & COMPLIANCE

Q13. Does an FCC license cover all my radios, or is it per device?
Answer - An FCC Part 90 license covers your licensed frequencies, not individual devices. You can operate any number of radios programmed to your licensed channels under a single license. There is no per-radio fee, per-device registration, or limit on fleet size.
This makes Part 90 licensing extremely cost-effective for larger deployments. A single license can cover a fleet of 5 radios or 500 radios equally — the license cost does not scale with device count.
Fleet Size, Per-Device, License Scope
Q14. What is a Special Temporary Authority (STA) and when do I need one?
Answer - A Special Temporary Authority (STA) is an FCC authorization for urgent radio operations that cannot wait for a standard license or modification. STAs are valid for up to 180 days.
Common STA scenarios include: temporary construction projects at an unlicensed site, short-term events (festivals, conventions), emergency response deployments, and testing new equipment before a permanent license is issued.
STAs are filed electronically using FCC Form 601 and must include a detailed narrative explaining the circumstances that justify the STA. The FCC typically processes STA requests within a few business days for emergency situations.
Tags: STA, Temporary Authority, Events
Source note: 47 CFR § 90.151 — Special Temporary Authority

CATEGORY 05 — RENEWALS & CHANGES

Q15. What happens to my FCC license if my business changes name, ownership, or location?
Answer - Any material change to your business or radio system requires action on your license:
Business name or ownership change: Update your FCC CORES account and file an administrative update on the license to reflect the new legal entity. Licenses are not automatically transferred in business sales — this must be done deliberately to ensure renewal notices continue to reach the right party.
New location: File a major modification and work with your frequency coordinator to re-evaluate channels and antenna parameters for the new site. You cannot operate at the new location under your old site license until the modification is granted (or conditional authority applies).
Adding a repeater or new coverage area: Requires a major modification and new frequency coordination before the system changes go live.
Minor administrative updates (updating contact info, correcting typos) can be filed directly through the ULS without coordinator involvement.
Tags: Modification, Renewal, Ownership Transfer, ULS
RENEWAL REMINDER CALLOUT:
Set two calendar reminders: one 6 months before expiration and one 90 days before. Confirm your CORES email address is current. Log into ULS at wireless.fcc.gov to verify your expiration date and file your renewal early.

    Q04. What is the difference between UHF and VHF — and which needs a license?
    Answer - Both UHF and VHF business radio bands require a Part 90 license for professional operation. Here is how to choose:
    UHF (Ultra High Frequency, 400–512 MHz): Better for indoor environments. Shorter wavelengths penetrate concrete, steel, and building materials more effectively. Best for: hotels, hospitals, warehouses, construction sites, and urban campuses.
    VHF (Very High Frequency, 136–174 MHz): Better for wide open outdoor coverage. Longer wavelengths travel farther over flat terrain. Best for: farms, golf courses, marinas, open construction sites, and parks.
    If unsure, your frequency coordinator will evaluate your site and recommend the right band. Many businesses program both bands into their fleet.

    CATEGORY 02 — COSTS & FEES
    Q05. How much does an FCC business radio license cost?
    Answer - There is no single flat fee — costs vary by service type and how much help you use. Here is a realistic breakdown:
    FCC filing fee (Part 90): approximately $65 per application
    Frequency coordinator fee: $100–$400+
    Professional filing assistance: $200–$500 (optional)
    Total Part 90 license: approximately $300–$800+
    GMRS individual license: $35 (no coordinator needed)
    The license covers unlimited radios on your licensed frequencies — you are not charged per device. Spread over a 10-year license term, this is a very low annual cost relative to the protection it provides.

    Q06. How long is an FCC license valid?
    Answer - Part 90 Industrial/Business licenses are valid for 10 years. GMRS licenses are also valid for 10 years. The license is not issued per device — it covers all radios operating under your licensed frequencies during that 10-year period.
    The FCC sends renewal reminder notices to the contact email on file in your CORES account. You can file for renewal up to 90 days before expiration. If your license lapses without renewal, you must reapply as a new application — which restarts the full coordination process.

    Q07. What are the penalties for operating without an FCC license?
    Answer - ⚠ CALLOUT — FCC Enforcement:
    FCC fines for unlicensed radio operation start at $10,000 per violation and can reach $25,000–$100,000 for willful or repeat violations. Hotel and hospitality operators have received fines in the $25,000–$50,000 range for commercial unlicensed use.
    Beyond monetary fines, the FCC can order equipment confiscation and operational shutdowns. Unlicensed operators also have no legal right to report interference — if another business is disrupting your communications, you have no recourse without a license.
    The cost of a license ($300–$800 over 10 years) is always less than a single FCC fine. Compliance is the practical choice, not just the legal one.

    CATEGORY 03 — HOW TO APPLY
    Q08. How do I apply for an FCC Part 90 business radio license?
    Answer - The standard Part 90 licensing process follows these steps:
    Step 1 — Define requirements. Determine your coverage area, band (UHF or VHF), whether you need a repeater, and if encryption is required for sensitive traffic.
    Step 2 — Engage a frequency coordinator. Provide your site address, antenna height, building description, and use case. The coordinator recommends channels and power levels that will not conflict with nearby licensees.
    Step 3 — Create an FCC Registration Number (FRN). Register at apps.fcc.gov/cores under your correct legal business entity name and address.
    Step 4 — File FCC Form 601 through the Universal Licensing System (ULS) at wireless.fcc.gov, using the coordinator's frequency data.
    Step 5 — Pay the filing fee (~$65) when prompted. The application is not accepted until payment clears.
    Step 6 — Receive call sign and license grant. Most uncontested applications are processed within 1–2 weeks after coordination is complete. Store the grant document in your compliance binder.

    Q09. What is a frequency coordinator and do I need one?
    Answer - A frequency coordinator is an FCC-certified private organization that recommends the most appropriate frequencies for your location before you file your application. For Part 90 new licenses and most major modifications, frequency coordination is required — not optional.
    Coordinators search the FCC database for nearby licensees, run distance-separation and contour studies, and recommend channels and power levels that will achieve your coverage without causing harmful interference to others. Some perform on-site spectrum scans to detect unlisted interferers.
    Well-known coordinators include the Enterprise Wireless Alliance (EWA), APCO International, and various regional organizations. Your radio dealer or vendor can often recommend one appropriate for your band and geography.

    Q10. Can I start operating before my license is granted?
    Answer - Yes — under Conditional Authority (47 CFR § 90.159). You may begin operating 10 business days after submitting a fully coordinated application and may continue for up to 180 days while your application is pending, provided that:
    - Your site is outside Canadian or Mexican border coordination zones.
    - You are not requesting any rule waivers.
    - Your antenna complies with FAA notification and environmental rules.
    If the FCC dismisses or denies your application, conditional authority ends immediately. For truly urgent deployments — emergencies, short-duration events — a Special Temporary Authority (STA) can be filed using Form 601 for up to 180 days with a written justification.

    Q11. What are itinerant frequencies and can my business use them?
    Answer - Itinerant frequencies are pre-designated channels in the Industrial/Business Pool that businesses can use when operating away from their primary licensed site — at a temporary job site, event, or new location not yet on their license.
    Itinerant operations do not require site-specific coordination or a modification to your existing license. However, they carry no interference protection — anyone else using the same itinerant channel has equal right to it. They are best used as a supplement to on-site licensed channels, not a replacement.
    Many businesses program itinerant channels alongside their licensed site channels in their radio fleet, with clear labeling so users know which channel to use and when.

    Q12. Do repeaters need their own FCC license?
    Answer - Yes. A repeater is a fixed base station and must be explicitly licensed. When you apply for your Part 90 license, you specify the repeater's location coordinates, antenna height, effective radiated power (ERP), and operating frequencies as part of the application.
    If you add a repeater after your initial license is granted, you must file a major modification and complete new frequency coordination before the repeater goes live. Operating an unlicensed repeater carries the same penalty exposure as any other unlicensed operation.

    CATEGORY 04 — OPERATIONS & COMPLIANCE

    Q13. Does an FCC license cover all my radios, or is it per device?
    Answer - An FCC Part 90 license covers your licensed frequencies, not individual devices. You can operate any number of radios programmed to your licensed channels under a single license. There is no per-radio fee, per-device registration, or limit on fleet size.
    This makes Part 90 licensing extremely cost-effective for larger deployments. A single license can cover a fleet of 5 radios or 500 radios equally — the license cost does not scale with device count.

    Q14. What is a Special Temporary Authority (STA) and when do I need one?
    Answer - A Special Temporary Authority (STA) is an FCC authorization for urgent radio operations that cannot wait for a standard license or modification. STAs are valid for up to 180 days.
    Common STA scenarios include: temporary construction projects at an unlicensed site, short-term events (festivals, conventions), emergency response deployments, and testing new equipment before a permanent license is issued.
    STAs are filed electronically using FCC Form 601 and must include a detailed narrative explaining the circumstances that justify the STA. The FCC typically processes STA requests within a few business days for emergency situations.

    CATEGORY 05 — RENEWALS & CHANGES

    Q15. What happens to my FCC license if my business changes name, ownership, or location?
    Answer - Any material change to your business or radio system requires action on your license:
    Business name or ownership change: Update your FCC CORES account and file an administrative update on the license to reflect the new legal entity. Licenses are not automatically transferred in business sales — this must be done deliberately to ensure renewal notices continue to reach the right party.
    New location: File a major modification and work with your frequency coordinator to re-evaluate channels and antenna parameters for the new site. You cannot operate at the new location under your old site license until the modification is granted (or conditional authority applies).
    Adding a repeater or new coverage area: Requires a major modification and new frequency coordination before the system changes go live.
    Minor administrative updates (updating contact info, correcting typos) can be filed directly through the ULS without coordinator involvement.

    RENEWAL REMINDER CALLOUT:
    Set two calendar reminders: one 6 months before expiration and one 90 days before. Confirm your CORES email address is current. Log into ULS at wireless.fcc.gov to verify your expiration date and file your renewal early.
