RF Interference Investigation
Something is breaking your wireless and you need it found now.
- Unknown / unidentified signals
- Wireless system disruption
- Intermittent communication failures
- Co-site interference
- Spectrum occupancy analysis
RF interference · signal location · wireless diagnostics
When wireless, sensors or comms keep failing — and no one can find why.
Independent RF engineering callout across the UK. I find the source of the interference, prove exactly what it is, and where it can be fixed, make the remedy myself.

What brings you here?
Start with the situation, not the terminology.
Choose the problem closest to yours. Each route explains the investigation, deliverables, timing and next step.
Live operational problem
Something is failing now
Wireless, telemetry, radio or GNSS is down, intermittent or costing throughput.
Priority callout → Planned risk reductionWe need to understand our RF risk
Baseline the site, identify exposure and leave with prioritised actions.
Planned RF survey → Product or system problemRF performance is below expectation
Bench or on-site measurement for manufacturers, integrators and product teams.
Engineering diagnostic → Independent evidenceWe need a defensible technical opinion
Independent RF and electronics evidence for disputes, insurers and legal teams.
Expert evidence →
You might recognise this
01
Wi-Fi and wireless links that drop out for no reason anyone can pin down.
02
Sensors, telemetry or RFID that read intermittently and cost you throughput.
03
Two-way radio or comms dead spots that appeared seemingly overnight.
04
GPS, timing or location systems drifting or losing lock for no clear reason.
What I do
Find it, locate it, fix what's fixable.
Five services, one engineer. The plain-English problem on top — the technical scope underneath, so the person who signs the PO and the person who evaluates the work both see what they need.
RF Source Location
There's a transmitter that shouldn't be there. I pinpoint it.
- Transmitter identification & location
- Direction finding
- Signal hunting
- Interference source identification
- On-site interference surveys
Wireless Systems Diagnostics
Your links, range or telemetry aren't performing as they should.
- Poor radio range
- Link reliability & dropouts
- Telemetry problems
- Antenna system investigations
- Receiver sensitivity / desense
RF Remediation & Fix
Once it's found, I engineer the fix — on my own bench.
- Shielding design & fabrication
- Filtering & ferrite / bonding
- Antenna re-engineering
- Enclosure modifications
- Bench-built custom remedies
Independent RF Investigation
You need a neutral, vendor-free technical verdict.
- Third-party technical assessment
- Failure analysis
- Performance verification
- Installer / vendor claim verification
- Dispute & expert support
Five ways to engage
A defined service, a clear output, and no mystery about the next step.
Every engagement is scoped around the affected system and site. The formats below give buyers and technical evaluators a practical starting point.
Priority RF Fault Callout
Phone triage, on-site spectrum investigation, source location where possible, tactical mitigation and a findings note.
Request a callout →Planned RF Health Survey
Site baseline, representative spectrum measurements, risk findings and prioritised practical actions.
Book a survey →GNSS Resilience Assessment
Dependency mapping, L1/L2/L5 survey, risk register, executive report and vendor-neutral mitigation plan.
View assessment →RF Engineering Diagnostic Sprint
An agreed bench or on-site test programme to isolate an RF performance problem and identify the next engineering action.
Discuss a diagnostic →RF Resilience Retainer
Baseline RF fingerprint, agreed response time, phone triage and priority access when a contracted site develops a fault.
Compare cover →Need supplier information before raising a purchase order?
Working with us →Company details, working practices, confidentiality, reporting, travel and commercial process are set out in one place.
Why independent matters
The difference between a diagnosis and a sales pitch.
01 / Neutral
Vendor-neutral
I don't sell the Wi-Fi kit, the signal boosters or the radios. So the diagnosis you get is the truth about your RF environment, not a route to a quote.
02 / Expert
RF-engineer-led
A microwave and RF engineering background, with the test gear to match. I find physical-layer causes your IT provider or installer simply can't see.
03 / Resolved
I can make the fix, not just report it
Most consultants hand you a PDF and leave. I can fabricate the shielding or filter and resolve the problem on site — diagnosis and remedy under one roof.
From call to fixed
How a priority callout works.
Call
Describe the symptoms. I triage on the phone and tell you honestly what attendance will involve.
Rapid attendance
On site, UK-wide, with the spectrum and microwave test equipment to characterise the problem properly.
Locate & prove
Spectrum analysis and direction finding to pin the source — and show you exactly what it is, on screen.
Fix
Tactical mitigation on the day where possible; engineered remediation quoted and delivered.
Can't afford the downtime twice?
An RF Resilience Retainer gives you a guaranteed response time, priority callout, and a baseline RF fingerprint of your site kept on file — so the next diagnosis is faster, and you're never starting cold.
New service
RF & EMF exposure surveys
Professional RF and electromagnetic-field measurements for homes, workplaces and properties near mobile phone masts.
