It’s not so far-fetched though, while bugs and hidden cameras in for example an Airbnb may not have flashing LEDs, they still emit RF and can be detected with a signal strength meter.

These outputs realized using the new technique are useful in measuring the peak signal strength, peak-to-average power, RF wave-shape, and average power. The function of RF power detectors is ...

RF power meters measure the strength of radio frequency signals in dBm or watts ... The ability to perform square-law detection. The resulting RF signal is proportional to the DC output voltage ...

[Ken Kawamoto] built the next best thing – an augmented-reality RF signal strength app for his smartphone. Built to aid in the repositioning of his router in the post-holiday cleanup ...

Accurate RF power amplifier characterization is critical for ensuring optimal system performance, especially at 5G ...
