Every radio wants to shout. Federated Wireless makes it raise a hand first. Before a commercial CBRS device transmits in the 3.5 GHz band, it checks in with a cloud service that knows where the radio is, which channel is available and how much power it may use. Somewhere nearby, a Navy radar or satellite earth station may have first claim. The software's job is to let the new network speak without stepping on the old one.
That makes the Arlington, Virginia company less like a carrier and more like invisible air-traffic control. It does not own the planes, airports or sky. It coordinates them. Founded in 2012 by wireless and national-security researchers, Federated Wireless spent years helping turn Citizens Broadband Radio Service - CBRS - from a regulatory experiment into working infrastructure. It now sells the coordination, planning and support needed by rural broadband providers, carriers, factories, campuses, venues and defense users to run private 4G, 5G and fixed-wireless networks.
The category is narrow, technical and rather consequential. The company says its operating data spans more than 250,000 CBRS radios and over 600 customers. Publicly named users and deployments include Charter, Comcast, Verizon, Carnegie Mellon, Tarana and the Department of Defense. Federated also says it moved past 75 percent share of the CBRS Spectrum Access System market in 2025. These are company-reported figures, but the shape of the business is visible: win the mandatory coordination layer, then build more valuable software above it.
The best product is a permission slip
CBRS opened 150 MHz of spectrum for a three-tier arrangement. Federal incumbents sit at the top. Priority Access License holders come next. General Authorized Access users fill the remaining room. Federated's Spectrum Controller keeps the seating chart. Its nationwide Environmental Sensing Capability network listens for incumbent activity; its cloud-based Spectrum Access System coordinates commercial radios and can move them when conditions change.
The 3.5 GHz seating chart
This is the first useful thing to copy. Start with the unavoidable pain. A network operator in CBRS needs an authorized coordinator to remain compliant; Federated surrounded that requirement with equipment integrations, installer training, migration help, analytics and human support. Its partner program lowers friction for radio makers and systems integrators because one pre-integration can speed every later customer deployment. Regulation creates the doorway, but interoperability and service keep customers inside.
The same pattern moved into 6 GHz. Standard-power Wi-Fi 6E and Wi-Fi 7 can travel farther and work outdoors, but only when an Automated Frequency Coordination system avoids incumbent microwave links. Federated received commercial FCC certification for its AFC in February 2024 and announced agreements with Cisco, HPE Aruba Networking, MediaTek, Airspan/Mimosa and Tarana. One cloud brain, many equipment makers, another band.
What failed first: the tidy forecast
The first thing to break was not the controller. It was the assumption that private wireless would arrive on the schedule promised by industry presentations. Federated raised about $200 million across publicly reported rounds, including a $58 million Series D in 2022, to scale spectrum platforms, private networking and partnerships. But enterprise private 5G developed more slowly than expected. CEO Iyad Tarazi later acknowledged layoffs as the market lagged.
That delay sharpened the strategy. Federated did not abandon shared spectrum; it leaned toward the piece it could repeatedly deliver: reliable coordination, plus the planning and optimization that make a deployment economical. In 2024 it launched Adaptive Network Planner. The product combines live spectrum availability with terrain, equipment specifications, antenna placement, propagation models and, where available, LiDAR and home-level coverage analysis. A broadband operator can compare tower sites, estimate service and prepare required coverage reporting without stitching together as many static tools.
“The spectrum was always there, but the computational tools to find it and use it at scale were not.”Iyad Tarazi, president and CEO
The change in mind is subtle but important. In the first chapter, software allocated spectrum safely. In the next, software should decide how to design the network around the spectrum that is actually available. Federated says its models learn from production measurements rather than simulations alone. That turns a decade of assignments, interference events and deployment outcomes into training material competitors cannot download from a public repository.
Physical AI, with a useful asterisk
In June 2026, Federated announced Spectrum AI, calling it a physical-AI platform for shared-spectrum planning and coordination. The phrase matters because radio signals must negotiate actual buildings, trees, hills and antenna angles. The company combines RF physics with GPU acceleration, NVIDIA's Sionna ray tracing and field measurements. It claims that favorable live deployments have produced up to five times more network capacity, up to 50 percent more usable spectrum, simulation speeds 100 to 1,000 times faster and site reductions of up to 50 percent.
“Up to” carries heavy freight. These are not universal outcomes, and public material does not disclose customer pricing for the platform. The verifiable cost story is capital and contracts: roughly $200 million in reported funding through 2022; a $16.2 million prototype award for a Marine Corps private 5G network; and a later 42-month sustainment contract worth more than $6 million. The Albany, Georgia deployment covers one million square feet with 40 gigabits per second of wireless capacity, built with JMA Wireless, HPE and Shared Spectrum. It shows where private 5G earns its keep: controlled space, expensive operational delays, machine connectivity and a customer that values security and support.

A moat made of dull, difficult things
Federated's differentiation is not one clever model. It is a stack of chores: regulatory approvals, coastal sensors, databases of incumbent antennas, OEM tests, cloud availability, audit trails, installer support and phone calls when a migration misbehaves. The company reported 100 percent spectrum availability with no high or critical interference cases through 2024 and the first quarter of 2025, then more than 30 months above 99.999 percent platform uptime. Reliability is both the product and the marketing.
That helps explain Google's decision to retire its own CBRS SAS by June 10, 2027. A thin, specialist market can be immaterial to a hyperscaler and existential to a focused vendor. Federated now advertises migration help and says it has transitioned more than 180,000 CBRS devices. The retreat of a formidable competitor is validation with a warning attached: category leadership is valuable only if the category produces durable revenue.
Competitors remain. Sony, RED Technologies, Key Bridge and Nokia appear among authorized or active spectrum coordinators. Celona, Ericsson, Nokia, Cisco and HPE occupy adjacent parts of private wireless. And the fiercest alternative is often architectural: ordinary Wi-Fi, a carrier contract or exclusive licensed spectrum may solve the problem with fewer moving parts.
When this playbook does not work
- The regulator has not opened a band or authorized automated coordination.
- Compatible radios and vendor integrations are too scarce to form an ecosystem.
- Terrain, foliage or interference ruins the link budget, however elegant the model.
- The customer does not value mobility, control or deterministic coverage enough to beat Wi-Fi on cost.
- The software vendor cannot maintain trusted sensors, uptime, security and human support for years.
The part worth stealing
Founders should resist copying the label and copy the sequence. Find a regulated workflow customers must complete. Become neutral plumbing for as many vendors as possible. Use support to observe where deployments fail. Turn those observations into structured operating data. Then build planning and optimization products that improve every time the core service runs.
Federated Wireless sits in an appealing market position because it is neither a radio maker nor a carrier. It can coordinate competitors without asking customers to replace the whole network. Its SaaS and managed-services model expands from a required transaction - permission to transmit - into design, deployment, reporting, case management and lifecycle optimization. That is a tidy expansion path inside a decidedly untidy physical world.
The wager now is whether operators believe better computation can postpone more concrete, steel and spectrum licenses. Spectrum AI will have to reproduce its headline gains outside selected deployments, at prices customers can justify. Federated's advantage is that it has spent 14 years watching radios encounter reality. Reality is an expensive teacher. The company would like to charge tuition.
