Independent RF compliance studies for cell sites you can trust.
OSC Engineering works for landlords, school districts, local planning departments, and attorneyswho need an independent read on the RF activity at their site — plus workers exposed to it and wireless carriers. On-site testing, expert review, and worker safety training grounded in 47 CFR § 1.1310 and FCC OET Bulletin 65.
Who we work with
What we do — and what you get when we're done.
Every engagement ends in a written, defensible deliverable. That's what regulators ask for. That's what landlords need to sleep at night. And that's what your file should show the next time someone asks “should I be worried about these antennas?”
Expert Review of RF Reports
Independent second-opinion review of existing EME, EMF, and RF exposure assessments — the reports a carrier, third-party engineer, or prior consultant already produced. We verify methodology against FCC OET Bulletin 65 and 47 CFR § 1.1310, check MPE calculations, and flag whether the stated conclusions actually follow from the data. Built for jurisdictions, building owners, attorneys, and operators evaluating someone else's work.
You get: Technical review memo with methodology critique and MPE recalculations where needed
Document & Lease Review
Independent review of carrier-submitted RF compliance reports, lease language, and proposed modifications — so landlords, school boards, and jurisdictions know what they're actually signing.
You get: Plain-English memo flagging risks & ambiguities
On-Site RF Testing
Direct measurement of RF energy at antenna sites using calibrated broadband probes — to verify compliance with the FCC Maximum Permissible Exposure (MPE) limits for both Occupational/Controlled and General Population/Uncontrolled environments.
You get: Field measurement report with MPE % at every accessible point
Mitigation & Implementation Labor
Hands-on installation of compliance signage, barriers, and lockout hardware. Coordination with carriers when antenna access requires power-down or rotation. End-to-end execution, not just paperwork.
You get: Photo-documented site close-out package
Compliance Recommendations
Specific, actionable mitigations to bring a non-compliant site into FCC compliance: signage, barriers, lockout procedures, antenna repositioning, power reductions, or worker training requirements.
You get: Written remediation plan with prioritized actions
Theoretical RF Studies
Computer-simulated modeling of antenna patterns, ERP, and exposure contours for proposed or existing sites — useful for planning, zoning submissions, and identifying restricted areas before construction.
You get: Predictive RF safety study with contour maps
Architectural Design
Concealment and aesthetic design for new and existing cellular installations — so a site reads as part of the surrounding architecture, not a piece of telecom equipment bolted onto a roof. Stealth treatment selection (palm tree, faux rock, parapet integration, steeple housing), screening, color matching, and design packages for landlord, jurisdiction, or zoning review.
You get: Design package with concealment recommendations, renderings, and material specs
Worker Safety Training
Site-specific RF safety awareness training for technicians, roofers, antenna riggers, building maintenance, and anyone working near transmitting equipment — so an Occupational/Controlled limit actually applies.
You get: Training records & certificates for site files
Many cell antennas are deliberately hidden.
Modern cellular installations are routinely concealed inside ordinary-looking structures so they blend into the landscape. That's good urban design — and it's exactly why RF compliance is so often overlooked. If you can't see the antenna, it's easy to forget the FCC exposure rules still apply to anyone working near it.

OSC Engineering finds these installations, verifies compliance against 47 CFR § 1.1310, and documents what's actually there — not just what's visible.

From first call to defensible report.
Typically 2–3 weeks for a full site assessment. Faster if you're up against a lease deadline or hearing.
Site intake call
We talk for 20 minutes. Antenna count, mount type, accessibility, who has the lease, and what you actually need (annual study, lease review, dispute mediation, training, build-out). Free, no obligation.
On-site work or desk review
Depending on scope: a half-day site visit with calibrated broadband probes, or a desk-based theoretical study from carrier-submitted RF specs. Either way, what we measure or model is what goes in the report.
Written report + recommendations
Plain-English MPE compliance report with photos, contour maps, and a prioritized remediation plan if anything's out of spec. Cited to 47 CFR § 1.1310 and FCC OET 65 so your attorney, insurer, or board can defend it.
“The FCC rules aren’t the hard part. Knowing where they actually apply at yoursite is.”

FCC OET 65
Trained · Independent · Carrier-Neutral
An independent expert on your side.
Cell antennas produce non-ionizing radiation, and the FCC sets exposure limits under 47 CFR § 1.1310. Wireless operators are required to perform compliance studies — but the building owner, school district, or jurisdiction often has no independent way to verify the numbers, the site walk, or the proposed mitigations.
That’s where we come in. We test, model, document, and train — with no equity in any carrier’s outcome. The report you get is the report the regulator and your insurer will accept.
Carrier-Neutral
No conflicts of interest — your file, your protection
Rules-First
FCC OET 65 + 47 CFR § 1.1310 + ANSI/IEEE C95.1
