Straight, practical troubleshooting from an RF engineer — organised by the symptom you're actually seeing, not by jargon. Find yours, understand what's likely causing it, and know when it's worth getting someone on site.
Poor range and random dropouts almost always trace to something on the air or something in the install. Here's how to tell which.
Read the guide →Intermittent telemetry has patterns. Walking through the usual culprits — congestion, desense, duty cycle and noise.
Read the guide →Why a "kilometres of range" radio fails across a yard — gateways, spreading factors, noise floor and siting.
In preparationBefore you replace the antenna: VSWR, cabling, connectors, placement and the things that masquerade as a bad antenna.
In preparationBroadband or narrowband? Internal or external? The distinction tells you almost everything about the fix.
Read the guide →SMPS, VFDs, LED drivers, plasma — the everyday equipment that raises your noise floor, and how it's tracked down.
Read the guide →What a spectrum analyser actually shows you — noise floor, occupancy, duty cycle, and spotting the odd one out.
In preparationTransmitters and receivers crammed together create desense and intermod. How to find it and design it out.
In preparationTrackers going dark, lost lock, position drift — how to tell jamming from a fault, and why plant and vehicles are targets.
Read the guide →On-demand sweeps and continuous monitoring that alert you the moment GPS is jammed — for plant yards and fleets.
Read the guide →One denies your GPS, the other deceives it. Which you're facing changes what you do next.
Read the guide →Hardened receivers, jam-resistant trackers, detection — what's realistic for plant and fleet, and the layer most miss.
Read the guide →A few minutes on the phone usually narrows it down. RF engineer, not a call centre.
