CBRS in 2026: What Is It Actually Being Used For?
Posted by Gordon R. on 11th Sep 2026
For several years, CBRS was frequently discussed as a technology with enormous potential. Private LTE networks, private 5G, industrial automation, smart cities, connected infrastructure, and enterprise IoT were all presented as possible applications.
In 2026, the conversation is changing. CBRS has moved well beyond early demonstrations and proof-of-concept deployments. It is now being used in factories, warehouses, airports, utilities, farms, campuses, fixed wireless networks, large commercial facilities, and other environments where organizations need more control over their wireless connectivity.According to the OnGo Alliance, as of July 2026 there were more than 446,000 active CBRS base stations, approximately 1.3 million active frequency grants, and more than 1,600 certified device models. Those numbers help answer an important question.
What is CBRS actually being used for?
The answer is not one single application. Instead, CBRS is becoming another tool in the wireless networking toolbox, filling an important space between traditional Wi-Fi and public cellular networks.
A Quick Refresher: What Is CBRS?
CBRS stands for Citizens Broadband Radio Service. It operates between 3550 and 3700 MHz, a 150 MHz portion of spectrum commonly referred to as the 3.5 GHz CBRS band.
Unlike conventional licensed cellular spectrum, CBRS uses a shared-spectrum model. Access to the spectrum is organized into three tiers:
- Incumbent Access, primarily protecting existing federal users and certain legacy operations
- Priority Access Licenses (PALs), which provide licensed priority access within defined geographic areas
- General Authorized Access (GAA), which allows eligible users to operate opportunistically on available CBRS spectrum
A Spectrum Access System, or SAS, coordinates spectrum use. CBRS devices communicate with the SAS so frequencies can be assigned while higher-priority users remain protected. This architecture is one of the reasons CBRS is so interesting. Organizations can deploy localized cellular networks without owning the type of nationwide licensed spectrum traditionally associated with major cellular carriers. The result is something that sits between Wi-Fi and conventional carrier cellular service.
Private LTE and Private 5G Networks:
One of the most important uses for CBRS in 2026 is private cellular networking. A private cellular network allows a business, government agency, school, utility, or other organization to operate LTE or 5G infrastructure across its own facility or property. Instead of relying entirely on a nationwide carrier network, compatible devices connect to localized cellular infrastructure.
Why do that when Wi-Fi already exists? The answer usually comes down to the requirements of the application. Wi-Fi is excellent for general-purpose connectivity. It is inexpensive, widely supported, and extremely capable. But there are environments where organizations need greater control over device authentication, mobility, coverage, traffic prioritization, or network architecture. Private cellular can be particularly useful when devices continuously move across a large property.
A forklift traveling through a distribution center, an autonomous vehicle moving through a manufacturing facility, or a maintenance technician traveling across a large utility property may need connectivity across multiple coverage areas. Cellular technologies were fundamentally designed around this type of mobility. CBRS gives organizations another way to build that cellular infrastructure locally.
Manufacturing and Industrial Automation:
Manufacturing has become one of the most natural applications for private CBRS networks. Modern factories are increasingly dependent on connected equipment. Sensors, cameras, autonomous mobile robots, industrial computers, tablets, machine monitoring systems, and asset tracking platforms can all require wireless connectivity. At the same time, factories can be challenging RF environments. Steel structures, machinery, storage racks, moving equipment, walls, piping, and other obstructions can create complicated propagation conditions. A network that works well in an office may behave very differently on a production floor.
CBRS does not eliminate those RF challenges. No wireless technology does. What private cellular can provide is another network architecture for addressing them. For example, an organization might continue using Wi-Fi for employee laptops and general Internet access while placing autonomous equipment, industrial IoT devices, or operational systems on a private LTE or 5G network. Rather than viewing CBRS as a Wi-Fi replacement, it often makes more sense to view it as an additional wireless layer.
Warehouses, Distribution Centers, and Logistics:
Warehouses and distribution facilities present similar challenges, particularly when mobility is involved. A large distribution center may contain barcode scanners, tablets, forklifts, cameras, inventory systems, autonomous mobile robots, sensors, and other connected equipment. Many of these devices move continuously.
Coverage may also need to extend beyond the warehouse itself. Loading docks, storage yards, parking areas, gates, and nearby outdoor facilities can all be part of the same operation. This is an area where CBRS can be particularly useful.
A properly designed private cellular network can provide connectivity across both indoor and outdoor areas, allowing compatible equipment to remain connected as it moves through the facility. That does not necessarily mean every device belongs on CBRS. Office computers and employee devices may remain on Wi-Fi, while selected operational equipment uses private cellular. The result can be a hybrid network in which each wireless technology is used where it makes the most sense.
Utilities and Critical Infrastructure:
Utilities are another important area for CBRS deployment. Electric utilities, water and wastewater operators, energy companies, and other infrastructure organizations frequently need connectivity outside conventional office environments. A water treatment facility, for example, may have equipment spread across buildings, tanks, pumping areas, outdoor infrastructure, and remote sections of a property.
Running Ethernet to every location may not be practical. Wi-Fi may not provide the desired coverage or mobility. Public cellular service may work well, but it also means relying on an external carrier network.
A private CBRS network provides another option. CBRS can support applications such as telemetry, cameras, sensors, field equipment, remote monitoring systems, operational communications, and connected infrastructure.
This can be particularly attractive when an organization wants greater control over its local communications network.
Fixed Wireless Access:
Not every CBRS connection involves a moving device. CBRS is also being used for Fixed Wireless Access, or FWA. In a fixed wireless deployment, a base station communicates with equipment installed at a fixed location. This could be a home, business, remote building, industrial facility, or another site requiring broadband connectivity.
Wireless Internet Service Providers, municipalities, enterprises, and other organizations can use CBRS as part of point-to-multipoint broadband networks.
Instead of running a physical cable all the way to a remote location, part of that connection is delivered wirelessly. This can be particularly useful in areas where installing fiber would be expensive, difficult, or time-consuming.
A directional antenna installed at the receiving location may communicate with a CBRS base station serving multiple sites. When the RF path is properly engineered, this can provide practical broadband connectivity without requiring a wired last-mile connection.
Airports, Campuses, and Large Facilities:
Airports, universities, hospitals, corporate campuses, stadiums, and other large properties are also strong candidates for CBRS. These environments frequently contain a mixture of indoor and outdoor spaces.
An airport, for example, may need connectivity inside terminals as well as around gates, maintenance facilities, hangars, service roads, parking areas, and other operational spaces. A university campus may need connectivity across classrooms, outdoor areas, maintenance facilities, parking lots, security systems, and remote buildings.
Traditional Wi-Fi remains extremely useful in these environments, but providing seamless coverage across an entire property can become complicated. Private cellular provides another layer that can be designed around the operational requirements of the facility.
Agriculture and Large Outdoor Properties:
Agriculture presents a very different networking environment. A farm may cover hundreds or thousands of acres. Equipment, irrigation systems, environmental sensors, cameras, buildings, and workers can be distributed across a large geographic area. Traditional indoor-oriented Wi-Fi networks are not designed to cover environments like this efficiently. CBRS can provide another option for creating localized wireless coverage across larger outdoor areas.
Potential applications include irrigation monitoring, environmental sensors, cameras, equipment telemetry, connected machinery, worker communications, and other IoT systems.However, the physics of the 3.5 GHz band still matter. CBRS generally does not have the same propagation characteristics as lower-frequency cellular bands. Trees, terrain, buildings, hills, and other obstructions can significantly affect the RF path.
Antenna height, antenna gain, radiation pattern, polarization, cable loss, and line of sight therefore become important parts of network design. For longer fixed links, Fresnel-zone clearance can also become an important consideration. CBRS can cover substantial areas, but successful deployment still requires good RF engineering.
Neutral Host and In-Building Cellular Coverage:
Another important development is the use of CBRS for neutral-host networks. Large buildings have historically faced a difficult problem when improving indoor cellular coverage. Supporting multiple mobile network operators can require substantial infrastructure, particularly in buildings where outdoor cellular signals have difficulty penetrating. Modern construction materials can make this problem worse. Low-emissivity glass, concrete, steel, and energy-efficient building materials can significantly attenuate cellular signals. Neutral-host architectures provide a way for shared infrastructure to support cellular connectivity inside a building.
CBRS has become part of this conversation because it can provide a common radio infrastructure that supports compatible neutral-host solutions. This is different from a conventional private cellular network.
A private CBRS network is generally designed to provide connectivity for an organization's own authorized devices and applications. A neutral-host network is designed to improve service for subscribers of supported public cellular networks. The underlying technology may overlap, but the use cases are different.
Public Safety and Temporary Networks:
CBRS can also be useful when organizations need localized wireless infrastructure that does not depend entirely on existing Wi-Fi or conventional wired connectivity.
Temporary command facilities, cameras, sensors, field equipment, and communications systems can potentially use private cellular infrastructure during planned events, construction projects, emergency operations, or other temporary deployments. It is important, however, not to position CBRS as a replacement for nationwide public-safety cellular networks.
Instead, CBRS can provide an additional local communications layer. That distinction matters. A CBRS network might support cameras, sensors, computers, telemetry, or other equipment within a defined operational area while public cellular networks continue providing wide-area connectivity.
CBRS Is Not Replacing Wi-Fi or Public Cellular:
One of the biggest misconceptions surrounding private cellular is that it is intended to replace Wi-Fi. For most organizations, that is unlikely. The more practical architecture is often a combination of technologies.
Ethernet may handle fixed infrastructure where maximum reliability and bandwidth are required. Wi-Fi may provide general connectivity for laptops, phones, tablets, and employee devices. Public LTE and 5G can provide connectivity when equipment travels outside the organization's property.
Private CBRS LTE or 5G can then handle applications that benefit from controlled cellular coverage within the organization's operational area. Think of CBRS as another tool rather than a universal replacement. The question is not whether CBRS is better than Wi-Fi. The question is whether CBRS is better suited to a particular application.
Why 3.5 GHz Makes Antenna Selection Important:
A private cellular network is still an RF network. That sounds obvious, but it can get overlooked when discussions focus heavily on network architecture, software, spectrum management, and 5G features. CBRS operates between 3550 and 3700 MHz. At these frequencies, antenna characteristics and installation details can have a significant impact on system performance.
What Should You Look for in a CBRS Antenna?
Not every cellular antenna is necessarily the right choice for CBRS.
Before selecting an antenna, verify several important specifications:
- Frequency coverage: The antenna should support the 3550 to 3700 MHz CBRS band.
- MIMO configuration: Make sure the antenna system provides the number of RF elements required by the modem or router.
- Radiation pattern: Determine whether the application requires omni-directional or directional coverage.
- Gain: Evaluate gain within the CBRS frequency range rather than relying solely on the antenna's advertised maximum gain.
- Cable and connector configuration: Verify connector compatibility, cable type, and cable length.
- Environmental rating: Outdoor installations may require UV-resistant materials, weatherproof construction, appropriate IP ratings, and suitable mounting hardware.
It is also worth looking carefully at antennas marketed simply as "5G antennas." 5G describes a cellular technology, not a specific frequency. An antenna advertised for 5G may cover CBRS frequencies, but that should be verified from the antenna's actual frequency specifications and, when available, RF performance data.
CBRS in 2026: Mature Technology, Expanding Applications:
The CBRS conversation looks considerably different in 2026 than it did during the technology's early commercial rollout. The infrastructure is being deployed. The device ecosystem has expanded. Private cellular networks have moved beyond demonstrations, and organizations have had enough time to identify where the technology provides practical advantages.
Manufacturing facilities are using private cellular for connected equipment and automation. Warehouses are connecting mobile operational systems. Utilities are extending connectivity to infrastructure. Fixed wireless operators are delivering broadband. Airports and campuses are building networks across large properties. Agricultural operations are connecting equipment across outdoor environments. Neutral-host deployments are addressing indoor cellular coverage.
Not every one of these applications requires CBRS. That is actually an important part of understanding the technology. CBRS becomes most valuable when it solves a specific networking problem better than the available alternatives.
What This Means for You:
If you are evaluating CBRS, the first question probably should not be, "Do we need a private 5G network?" A better question is: "What connectivity problem are we trying to solve?"
If the problem involves large-area private coverage, mobile equipment, industrial IoT, fixed wireless connectivity, network control, or devices that do not fit comfortably within a conventional Wi-Fi architecture, CBRS may be worth considering. From there, the discussion becomes an RF engineering problem as much as a networking problem. The radio, antenna, coaxial cable, connectors, antenna placement, MIMO configuration, terrain, building materials, and RF environment all contribute to the final link.
A well-designed CBRS network is not simply a collection of 5G hardware. It is a complete RF system. When selecting antennas for CBRS-capable routers, gateways, modems, and fixed wireless equipment, verify that the antenna supports the 3550 to 3700 MHz CBRS frequency range and matches the RF configuration of the connected device.
