Key points
- GAA needs no license application or auction, because the FCC's rules themselves authorize it.[4] Each base station radio must still be FCC-certified, registered with a SAS and able to follow SAS instructions within 60 seconds.[1]
- GAA users get no protection from each other. Protection on a channel comes only with a Priority Access License (PAL), a 10 MHz county license you can buy or lease.[1] The FCC's license file of September 27, 2026 lists 20,185 active PALs in 3,220 counties (Private5G.com analysis).[5]
- Lower-power Category A radios can go indoors or outdoors, but an outdoor antenna can be no higher than 6 m above average terrain. Higher-power Category B radios must be outdoors and professionally installed.[1]
- Near the coasts and some federal sites, the SAS may move or pause your radios while federal radar is active.[4][6] A 2024 change shrank the areas affected. The FCC said it would let SASs serve about 72 million more people without periodic interruptions.[7]
- Plan under today's rules. The FCC's 2024 proposal to change them had no final order as of October 1, 2026.[8][9] Google's SAS will shut down on June 10, 2027, so its users must move.[10]
Do you need a license to use CBRS?
Not for the open tier. CBRS shares one band among three groups of users, called tiers. Each tier is protected from the tiers below it, and the SAS enforces that order.[4]
GAA (the open tier) needs no license application or auction, because the FCC's rules themselves authorize it.[4] Any eligible organization with certified equipment can use it.[1] The trade-off is protection. GAA users get none from other GAA users, and they must accept interference from the tiers above.[1] In practice they rely on their SAS to coordinate channels. GAA users with higher-power Category B radios are also expected to cooperate on their choice of channel.[1]
A PAL (Priority Access License) protects you from GAA users on one 10 MHz channel in one county. That protection covers only the area around your radios that are in use.[1] You can buy or lease a PAL from a current holder.[1] The PAL section below explains how they work.
| Tier | Who | Protection | How you get access |
|---|---|---|---|
| 1. Incumbents (the band's existing users) | Federal users such as Navy radar on ships, plus registered satellite ground stations (fixed-satellite service, or FSS, earth stations) | Protected from all CBRS users | Existing federal allocation, or yearly FSS registration with the FCC[4][1] |
| 2. Priority Access (PAL) | PAL holders and the companies that lease from them | Protected from GAA users inside the PAL Protection Area around their radios | Auction 105, or buying or leasing a PAL from a holder[1] |
| 3. General Authorized Access (GAA) | Any eligible organization using certified equipment | None from other GAA users; must accept interference from the tiers above | No license application (licensed by rule); register each radio with a SAS[1][4] |
Incumbents are the band's existing users, and they come first. The federal users include Department of Defense radar on ships in coastal areas and at some inland sites.[4] Satellite ground stations that want protection must renew their registration every year.[1] Near federal sites, your radios may have to change channel or pause. The section on federal radar below explains when.
Which part of the band you can use. CBRS covers 3550–3700 MHz, often called the 3.5 GHz band.[1] GAA users may use any of it. PALs exist only in the lower 100 MHz, 3550–3650 MHz.[1] The upper 50 MHz, 3650–3700 MHz, is reserved for GAA users and former wireless broadband licensees from before CBRS.[1] Your SAS, not you, picks the exact channel. A PAL holder can ask for a particular channel but is not guaranteed one.[1]
| Range | Who can use it | Key limits |
|---|---|---|
| 3550–3650 MHz (100 MHz) | PAL holders and GAA users | Up to seven 10 MHz PALs per county; GAA users may use PAL channels that are not in use[1] |
| 3650–3700 MHz (50 MHz) | GAA users (and former licensees from before CBRS) | No PALs are issued here[1] |
| Whole band | All CBRS users, below the incumbents | The SAS must protect federal radar and registered satellite ground stations[1] |
IncumbentsPALGAAEach tier is protected from the tiers below it. GAA users get no protection from each other.
What do you need to run a private LTE or 5G network on CBRS?
You need certified radios, a SAS account and devices that work in the band. Some radios also need a trained installer, and you choose between GAA and a PAL. The FCC's CBRS rules (Part 96) split CBRS equipment into two kinds. Base station radios are called CBSDs (Citizens Broadband Radio Service Devices). End user devices, such as phones and routers, work under a radio's control.[1] This guide calls them radios and devices.
On spec sheets, CBRS appears as Band 48 for LTE and n48 for 5G. Both cover the full 3550–3700 MHz.[2][3] The FCC's rules don't require a particular technology. Each radio reports its technology (air interface) to the SAS when it registers.[1]
- Choose certified radios that support Band 48 or n48
Band support alone is not enough. A SAS must confirm that a radio's FCC ID belongs to certified equipment before it authorizes the radio.[1] In 2024 the FCC said it had certified more than 250 base station radio models for the band.[4] See the equipment directory and complete network kits.
- Open a SAS account that covers every radio
Every base station radio must register with a SAS.[1] Our SAS administrator guide compares the options.
- Book a trained installer if you need one
Higher-power Category B radios need a Certified Professional Installer (CPI).[1] So do lower-power Category A radios that cannot work out their own location.[6] The section on power below explains the categories.
- Check every device
Phones, routers and other devices must support Band 48 or n48. Check each device's FCC ID and spec sheet; our CBRS device guide shows how. In 2024 the FCC said it had certified more than 750 end user devices for the band.[4]
- Choose GAA or a PAL
GAA has no license cost but no protection from other GAA users. Protection requires holding or leasing a PAL.[1]
- Check your site
The CBRS map shows radar zones, PAL holders and antenna-height checks for a location. The project planner helps you scope devices, traffic and site details before you pick equipment.
Who uses CBRS. Mobile operators, wireless internet providers, cable operators, utilities, schools and private network operators all use the band.[4] An industry report released in June 2026 counted more than 442,000 deployed base station radios. CBRS advocates commissioned the report.[11] It said 75% of 1,580 U.S. private 5G networks use CBRS.[11] Our private LTE guide covers the rest of the network design.
Will federal radar interrupt your network?
It depends on where your radios are. The FCC protects federal radar with Dynamic Protection Areas (DPAs). These are zones around federal radar operations, and a SAS protects them only while they are active.[4] Under the industry SAS requirements, each DPA has a neighborhood: the area within a set distance of its protection points.[6] Radios outside every neighborhood are not moved or paused for DPAs.[6]
Being in a neighborhood means possible interruptions, not a ban. When a DPA is active, the SAS works out which radios in its neighborhood to move or pause. The aim is to keep their combined signal under the protection limit.[6]
There are three kinds of DPA. Some turn on when a sensor network, called the Environmental Sensing Capability (ESC), detects radar. Others turn on when federal users schedule operations, and some are always on.[4] NTIA (the National Telecommunications and Information Administration) publishes a map file for each kind.[12]
| Type | What it protects | When it is active | Entries in NTIA's current file |
|---|---|---|---|
| Sensor-activated (E-DPA) | Radar on ships along the coasts, and some land-based facilities | When an ESC sensor detects radar | 105 (file version 2.0.5)[12] |
| Scheduled (P-DPA) | Federal test and training ranges, and some coastal areas | When federal users schedule operations through the federal TARDyS3 portal | 14 (file version 2.0.7)[12] |
| Always active (GB-DPA) | Ground-based radar sites operating below 3.5 GHz | Always | 100 (file version 2.0.6)[12] |
Neighborhoods can be large. NTIA's file for sensor-activated DPAs lists separate distances by radio category, indoor or outdoor use, and antenna height. Across its 105 DPAs, the distances run from 1 km to 248 km (Private5G.com analysis).[12]
- DPA inactive. Radios inside the DPA's neighborhood transmit normally on their SAS grants.
- Radar detected. An ESC sensor detects federal radar offshore and reports it to the SAS. Portal-activated DPAs switch on when federal users schedule operations instead.
- The SAS decides, within 300 seconds. It works out which radios in the neighborhood to move or suspend so that their combined signal stays under the protection limit.
- Radios comply, within 60 seconds. Here radio A moves to another channel and radio B is suspended. Radio C is outside the neighborhood, so it is not a candidate.
Under a 2018 waiver order, DPAs replaced the fixed coastal Exclusion Zones in the original rules, for SASs that support DPAs.[4] Some inland radar sites are still protected by fixed Exclusion Zones.[4]
The 2024 change. On June 12, 2024, the FCC let SASs use a new way to model interference near DPAs, which NTIA had recommended.[7][13] It shrinks DPA neighborhoods.[7] The FCC said SASs using it could serve about 72 million more people, about 240 million in total, without periodic service adjustments.[7] Atlanta, Phoenix, Las Vegas, San Antonio and Pittsburgh were among the metro areas it named.[7] On July 3, 2024, it approved five SASs to use the new model: Federated Wireless, Google, Key Bridge, RED Technologies and Sony.[14] The For engineers section below has the modeling details.
The CBRS map draws NTIA's current DPA neighborhoods for a site. It also shows PAL holders by county, and runs the device-category and 6 m antenna-height checks. It is planning context. Only a SAS can authorize a radio or say when a DPA is active.
What does a PAL give you, and who holds them?
A PAL protects you from GAA users on one channel, but only around your radios that are in use.[1] It is a ten-year license for one 10 MHz channel in 3550–3650 MHz, covering one county.[1] A county can have at most seven PALs, and one licensee can hold at most four in the same county.[1] Holders must show substantial service, the FCC's test of real use, by the end of the first term. Otherwise they lose the license.[1]
Protection is narrower than the license. A PAL is protected only inside its PAL Protection Area (PPA).[1] By default, the SAS draws this area around the holder's registered radios that are in use, and keeps it inside the license area.[1] Outside the PPA, GAA users may use the PAL's channel. A radio that does not contact its SAS for seven days drops out of the PPA calculation.[1]
What a PAL in your county means. It does not mean its channel is in use at your site. Only the PPA is protected. SASs compute it from registration data that they may not publish without the registrant's permission.[1] The CBRS map shows the PAL holders for any county, from the FCC license file described below.
The 2015 rules had planned PALs for census tracts, with three-year terms. In October 2018, before any PALs were auctioned, the FCC switched to county license areas and renewable ten-year terms.[15]
| Measure | Value |
|---|---|
| PALs offered | 22,631: seven in each of 3,233 counties[16] |
| Bidding closed | August 25, 2020[17] |
| Winning bidders | 228[17] |
| PALs won | 20,625[17] |
| Gross winning bids | $4,585,663,345[17] |
| Net winning bids (after bidding credits) | $4,543,232,339[17] |
| First licenses granted | 17,450 PALs on March 12, 2021[18] |
Who holds PALs today (Private5G.com analysis). We counted the PAL records in the FCC's weekly license file from its Universal Licensing System (ULS). The file was created September 27, 2026.[5] It lists 20,185 active PALs in 3,220 counties. That is 440 fewer than were won at auction. ULS does not record why, and we did not trace each license.[5] All seven channels are licensed in 2,328 counties. Thirteen license areas, most of them in Alaska, have no PAL record at all. Of the active PALs, 17,713 expire in 2031. The file names 304 distinct licensees.[5]
| Licensee (as named in ULS) | Active PALs | Counties |
|---|---|---|
| Wetterhorn Wireless L.L.C. | 5,491 | 3,127 |
| SAL Spectrum, LLC | 1,424 | 529 |
| AMG Technology Investment Group, LLC | 1,068 | 489 |
| Uniti Services LLC | 1,014 | 296 |
| Comcast OTR1, LLC | 830 | 306 |
Where can your radios go, and how much power can they use?
Your choice of radio decides where it can go and who must install it. Base station radios come in two categories: Category A (lower power) and Category B (higher power).[1] Devices such as phones have their own, lower power limit.[1]
| Kind | Where it can operate | Other rules |
|---|---|---|
| Device (phone, router or other end user device) | Only under the control of a base station radio that has authorized it | Must follow that radio's instructions within 10 seconds[1] |
| Category A radio (lower power) | Indoors or outdoors; an outdoor antenna can be no higher than 6 m above average terrain | Registers as indoor or outdoor[1] |
| Category B radio (higher power) | Outdoors only | Must be professionally installed and register its antenna details; in 3550–3650 MHz, authorized using ESC information[1] |
The category follows how a radio is used, not its label. A Category A radio mounted outdoors above the 6 m limit, or run above Category A power, counts as Category B.[1] It then takes on every Category B rule. A device run above its power limit counts as a base station radio. All CBRS transmitters must use the lowest power they need.[1]
The 6 m limit is not height above the ground. It is height above average terrain (HAAT): your antenna's height compared with the average ground level around it.[1] The industry SAS requirements take that average from 3 to 16 km away.[6] So a short mast on a hilltop can be over the limit, while a taller one in a valley may not be. The CBRS map runs this check for a location and antenna height.
How HAAT is measured
Average the terrain elevation from 3 to 16 km out along eight radials.
HAAT = antenna height above mean sea level − that average
Short mast on a hilltop
More than 6 m HAAT: outdoors, a Category A radio here is treated as Category B.
Taller mast in a valley
Within 6 m HAAT: the outdoor Category A height limit is met.
- Average terrain
- 6 m above average terrain
- Terrain that is averaged (3–16 km out)
- Sketches, not to scale
Trained installers. Category B radios must be professionally installed, but the FCC's rules do not define what that means.[1] The FCC asked industry to accredit installers.[4] The Wireless Innovation Forum (WInnForum), an industry group, now accredits training programs for Certified Professional Installers (CPIs).[19] Equipment vendors, network operators, SAS operators or training firms can run these programs.[19] Under WInnForum's requirements, a CPI must also install any Category A radio that cannot work out its own location accurately enough.[6] The CPI is then responsible for the registration data sent to the SAS.[6] The FCC cited industry reports of more than 5,600 CPIs in 2024.[4]
What does a SAS do, and which ones operate?
Every base station radio needs a SAS account, and the SAS controls when and where it may transmit. A SAS is an FCC-authorized system that authorizes and manages spectrum use in CBRS.[1] SAS administrators may charge users a reasonable fee.[1] The FCC certifies each one for a five-year term that it can renew.[1] Under Part 96, a SAS must:
- check each radio's identity and location, and confirm that its FCC ID belongs to certified equipment;[1]
- tell each radio which channels it may use and its maximum power at that location;[1]
- enforce the zones that protect federal sites (Exclusion Zones and Protection Zones), and act on ESC reports of federal radar;[1]
- calculate and enforce PAL Protection Areas the same way as every other SAS;[1]
- protect registered satellite ground stations, and coordinate GAA users of Category B radios.[1]
Radios must obey quickly. A radio must stop transmitting, change channel or change power within 60 seconds of a SAS instruction.[1]
The ESC. An ESC is a sensor network, run by a non-government company, that detects federal radar and reports it to SASs.[1] After an ESC reports federal use, the SAS has 300 seconds to pause or move the affected radios.[1] In 3550–3650 MHz, Category B radios can be authorized only in line with ESC information.[1]
Which SASs operate. In March 2026 the FCC said it had certified eight SAS administrators and that six still operate.[20] Google, one of the six, stopped accepting new customers on June 10, 2026. It plans to shut down on June 10, 2027.[10] Our SAS administrator guide lists each administrator's status and has a checklist for moving.
What could change at the FCC?
No rule change has been adopted yet. As of October 1, 2026, the FCC had not adopted an order on its 2024 proposal. Part 96 in the online Code of Federal Regulations (eCFR), current through September 30, 2026, contains none of the proposed changes.[1]
What the FCC proposed. In August 2024 the FCC proposed a broad update to the CBRS rules, in a document called FCC 24-86.[4] It proposed writing all three kinds of DPA into Part 96 and requiring every SAS to use them. It asked whether to add higher-power classes of base station radio.[4] It also sought comment on SAS outages, the installer rules and private indoor networks.[4] Two more technical topics were timing coordination between networks (TDD synchronization) and limits on signal that leaks outside a channel (out-of-band emissions).[4] The same document ruled that NTIA and the Department of Defense may obtain radio registration data from SASs.[4]
Comments closed on November 6, 2024, and replies on December 5, 2024.[21] In February 2026, the Technology Policy Institute described it as an open proceeding with no order.[8] In May 2026, Broadband Breakfast called it a pending rulemaking.[9]
The open questions are power and reallocation. According to Broadband Breakfast, Verizon has proposed a much higher-power radio category.[9] AT&T has floated relocating CBRS users and auctioning the band. CBRS users and advocates oppose both.[9] The July 2025 budget law requires the FCC to auction 800 MHz of spectrum, and it did not exempt CBRS.[9]
In February 2026, Arpan Sura, a top adviser to FCC Chairman Brendan Carr, said the agency had more immediate spectrum goals than CBRS changes.[8][9] Sura also said the agency wanted better data on how the band is used.[8][9]

For engineers: Part 96 limits, HAAT, PPAs and DPA modeling
CBRS is governed by 47 CFR Part 96: 150 MHz of mid-band spectrum at 3550–3700 MHz.[1] In 3GPP specifications it is LTE Band 48 and NR band n48, both using time-division duplex (TDD).[2][3] The wider NR bands n77 (3300–4200 MHz) and n78 (3300–3800 MHz) overlap CBRS.[3]
| Device class | Max EIRP | Max PSD | Where and how |
|---|---|---|---|
| End user device | 23 dBm/10 MHz | None listed | Authorized and controlled by a CBSD; must follow its instructions within 10 seconds[1] |
| Category A CBSD | 30 dBm/10 MHz | 20 dBm/MHz | Indoor or outdoor; outdoor antennas no higher than 6 m HAAT; registers as indoor or outdoor[1] |
| Category B CBSD | 47 dBm/10 MHz | 37 dBm/MHz | Outdoor only; professionally installed; in 3550–3650 MHz, authorized using ESC information; registers antenna gain, beamwidth, azimuth, downtilt and height[1] |
CBSDs must know their location to within 50 m horizontally and 3 m vertically. They report antenna height above ground, in meters, when they register.[1]
HAAT method. Part 96 does not define how to compute HAAT.[1] WINNF-TS-0112 averages terrain elevation from 3 to 16 km out along eight radials. It subtracts that average from the antenna's height above mean sea level.[6]
PALs. By default, the PPA is the −96 dBm/10 MHz contour around the licensee's registered, in-use CBSDs, limited to the license area.[1] With at most seven PALs (70 MHz) per county under 47 CFR §§96.11 and 96.13, at least 80 MHz is never PAL-licensed in any county.[1] Our PAL counts use the ULS records with radio service code PL.[5]
DPA modeling. The modified aggregate interference model of June 2024 assumes an 80% TDD activity factor and 20% network loading. Together these cut each CBSD's modeled EIRP by 8 dB.[7] The model uses median terrain-based propagation loss.[7] It adds clutter loss for CBSDs with antennas 6 m or lower above ground that sit at least 250 m from a DPA boundary.[7]
Grandfathered users. Part 90 wireless broadband licensees used 3650–3700 MHz before CBRS. They had until January 8, 2023 at the latest to move onto CBRS rules or stop operating.[4]
Common questions
Is CBRS free to use?
GAA use has no license fee or auction, because the FCC's rules themselves authorize it.[4] You still pay for certified equipment and for SAS service. SAS administrators may charge a reasonable fee, which the FCC can review.[1] PALs cost whatever the market charges; Auction 105 raised $4.54 billion in net bids.[17]
Do I need an FCC license to use CBRS?
Not for GAA. Any eligible organization may run base station radios on a GAA basis. Each radio must register with a SAS and follow its instructions.[1] You need a PAL, or a lease of one, only if you want protection from GAA users on a channel in a county.[1]
Is CBRS 4G or 5G?
Both. The cellular standards call the band LTE Band 48 and 5G band n48, and each covers 3550–3700 MHz.[2][3] The FCC's rules don't require a particular technology. Each radio reports its technology to the SAS when it registers.[1]
What happens when the Navy needs the band?
A sensor detection or a booking in the federal scheduling portal activates the relevant DPA.[4] The SAS then moves or pauses radios in that DPA's neighborhood as needed. Radios outside every DPA neighborhood are not moved or paused for this.[6] The SAS has 300 seconds after a sensor detection to act, and each radio has 60 seconds to follow a SAS instruction.[1]
Can phones use CBRS?
Yes, if the phone supports Band 48 or n48.[2][3] A phone counts as an end user device, which has a lower power limit than a base station radio. It may transmit only under the control of an authorized base station radio.[1]
Does Google's SAS shutdown affect my network?
Only if your radios are registered with Google. Google stopped accepting new customers on June 10, 2026. It will shut its SAS down on June 10, 2027, so existing customers must move to another FCC-authorized SAS before then.[10] Our SAS administrator guide has a checklist for the move.
