We know how operators, vendors, and integrators all think. That's what makes our designs work.

RFO Tech brings 20+ years of in-building RF experience across carriers, RAN vendors, and third-party integrators — AT&T, T-Mobile, Verizon and the full ecosystem around them. From first capacity model through final commissioning, one team, no handoffs.

We've worked every side of the table.

Most RF consultants know one perspective — the vendor, the integrator, or the carrier. Our engineers have worked all three: directly with AT&T, T-Mobile, and Verizon, alongside RAN and DAS vendors, and as third-party specialists embedded in operator deployments. That means we understand what carriers will and won't approve, where vendor specs diverge from field reality, and how to get a system commissioned without the back-and-forth that delays most projects.

RFO Tech is a focused team of 2–5 RF engineers based in Irvine, CA. We take on hospitals, stadiums, and Fortune 500 facilities where performance isn't optional — and we stay with the project from design through sign-off. No account managers, no junior handoffs.

What we do

Full-scope in-building wireless — from the first site walk to the final test report.

Cellular in-building design

DAS and Wi-Fi system design for venues of any size — sized right from the start.

Benchmark & validation

Field surveys and RF data collection with reports carriers and contractors can act on.

System optimization

Existing system underperforming? We assess, identify gaps, and tune to your targets.

RAN-DAS commissioning

Operator process knowledge to integrate, commission, and validate before go-live.

Fiber & cable testing

Fiber and coax diagnostics with full result reports. Fast turnaround.

Not sure what your venue needs?

Use our capacity estimator to see how your band selection and user load affects throughput and sector count. It's a starting point — when the numbers actually matter, that's where we come in.

Estimates are based on theoretical spectral efficiency and typical indoor loading assumptions. Actual performance depends on site survey, interference environment, and system design. These numbers are a directional starting point — not a design specification.
