RF jammer detection and investigation based on measured evidence
If GPS, mobile, Wi-Fi, CCTV, telemetry or tracking equipment is failing unexpectedly, deliberate RF jamming is one possible cause — but it is not the only one. Our RF jammer detection & investigation service is designed to establish what is actually happening in the radio-frequency environment.
An RF engineer attends the affected location, measures the relevant spectrum and compares abnormal RF activity with the reported failure. Where a suspect transmission can be measured for long enough, directional techniques can be used to help narrow down its source.
Commercial investigation, not guesswork: the purpose is to determine whether the evidence is consistent with deliberate jamming, accidental interference, receiver overload, equipment faults or another RF problem.
Identify abnormal RF activity
Measure signal level, bandwidth, timing and occupancy in the frequencies used by the affected system.
Correlate signal and failure
Compare suspect transmissions with GPS loss, network dropouts, tracker gaps or other operational symptoms.
Trace the source
Use directional antennas and source-location techniques where the signal strength and transmission duration permit.
Systems we investigate for suspected jamming
- GPS and GNSS navigation, positioning and timing
- Vehicle and asset tracking systems
- GSM, 4G and 5G cellular communications
- Wi-Fi networks, wireless CCTV and security systems
- Telemetry, IoT and remote monitoring
- Wireless alarms, access control and radio links
What happens during an RF jammer investigation?
Define the incident
We establish what fails, where it happens, how often it occurs and which radio technologies are involved.
Survey the relevant spectrum
Professional spectrum-analysis equipment and suitable antennas are used to examine the frequencies associated with the affected equipment.
Capture and classify suspect signals
Frequency, bandwidth, level, timing and repetition provide evidence about whether an RF event is consistent with jamming or another form of interference.
Correlate with the operational failure
A strong conclusion requires more than finding an unusual signal. We look for a relationship between the RF activity and the actual system failure.
Source location where practical
If the transmission is present and measurable, directional techniques can help identify the area or equipment from which it originates.
Intermittent RF jamming investigations
Some incidents last only seconds or minutes. In these cases, RF monitoring and logging may be more useful than a single snapshot. Captured events can be compared with timestamps from trackers, CCTV, telemetry or network logs.
RF jammer or ordinary interference?
Faulty electronics, switching power supplies, broadband electrical noise, nearby transmitters and receiver desensitisation can produce symptoms that resemble deliberate jamming. Our investigation is deliberately evidence-led so that a jammer is not blamed without technical support.
UK-wide service: on-site RF jammer detection and investigation is available for commercial, industrial, fleet, security and specialist applications across the UK.
When to request an investigation
This service is particularly useful when wireless failures are repeated, location-specific, commercially disruptive or security-sensitive, and normal IT or equipment troubleshooting has not identified the cause.
