Hidden Interference (RFI) Basics

Not all interference is Wi-Fi. Cheap electronics, bad power supplies, lighting, and industrial equipment can raise the noise floor and quietly destroy performance.

Common hidden sources

LED lighting drivers, failing power supplies, motors, microwave leakage, cheap cameras, building automation, and poorly-shielded cabling.

What it feels like

Random drops, voice choppiness, latency spikes, throughput collapse at certain times, or specific rooms that behave ‘haunted.’

How OCWS hunts RFI

We look for noise patterns, correlate performance to time/location, and isolate candidates using measurement—not guesswork.

Pro tip

If performance changes when certain equipment is on/off, that’s a strong RFI clue. Don’t replace your router first—measure and confirm.
