INTERACTIVE LESSON & SIMULATOR
Interactive Visualizer: 5G Low-Band vs. C-Band vs. mmWave
Simulate exterior wall penetration, Massive MIMO beamforming, and check which 5G bands your consumer RF meter can actually measure.
5G isn't one frequency band
"5G" covers several different frequency ranges deployed under the same name. Much of it — often called sub-6 — reuses frequency territory close to earlier cellular and Wi-Fi bands, generally below 6 GHz. Some deployments also use millimeter-wave (mmWave) bands, roughly in the 24–40 GHz range depending on the country, to support very high data rates over shorter distances. See our article on 5G safety evidence for what's changed about exposure guidelines, not just frequency.
What our documented meters actually cover
Checking manufacturer-published RF ranges for the three instruments we profile: the TriField TF2 is specified to 6 GHz, the Safe and Sound Pro II to 8 GHz, and the GQ EMF-390 up to 10 GHz per the manufacturer. That comfortably covers sub-6 5G, 4G, Wi-Fi and Bluetooth. None of the three is specified to reach the 24–40 GHz mmWave range some 5G deployments use — a reading from any of them can't tell you what's happening at those higher frequencies, because they're not built to sense it.
Why this matters for interpreting a reading
A meter reads total RF energy within its sensed range and antenna response — it doesn't label a signal as "5G," "4G" or "Wi-Fi," and a meter that tops out below mmWave frequencies will simply show nothing for that portion of the spectrum, not a low or safe reading specific to it. If your question is specifically about mmWave 5G, a sub-6 GHz-capable consumer meter isn't the right instrument to answer it, whatever the reading shows.
A practical way to use a meter around 5G
For the sub-6 GHz portion of 5G — the large majority of current deployments — any of our three documented meters can register RF activity in that range, useful for the same relative comparisons (closer vs. farther, before vs. after) that apply to any RF source. Treat it as one data point about broadband RF energy near you, not a measurement of "how much 5G" you're exposed to.
