Find the Right Meter For Your Needs
While it is always a good idea to have a certified building biologist test your home with professional equipment, you are able to purchase these devices yourself and ensure your home is ‘in the green’ as much as possible. I personally like the Safe and Sound Pro II meter, however it does have some limitations, being only able to detect RF within the 200 MHz to 8 GHz range.
Wi-Fi and Bluetooth 2.4 GHz: Wi-Fi devices, especially older ones, often operate in the 2.4 GHz band. This band is commonly used by Wi-Fi standards such as 802.11b, 802.11g, and 802.11n. Bluetooth technology primarily operates in the 2.4 GHz band.
Wi-Fi 5 GHz: Newer Wi-Fi standards, such as 802.11ac and 802.11ax (Wi-Fi 6), operate in the 5 GHz band. This band offers more channels and higher data rates but has shorter range compared to 2.4 GHz.
Wi-Fi 60GHz: WiGig, operating in the 60 GHz band, is a high-frequency wireless technology designed for ultra-fast data transfer and low latency. 802.11ad and 802.11ay are WiGig standards.
3G: Typically operates in the 850 MHz and 2100 MHz bands.
4G (LTE): Commonly uses the 700 MHz (Band 28), 1800 MHz (Band 3), 2100 MHz (Band 1), and 2600 MHz (Band 7) bands.
4G (LTE-A): LTE-A can use carrier aggregation, combining multiple frequency bands for increased data speeds. Additional bands, including 2300 MHz (Band 40), 2500 MHz (Band 41), and others, may be used depending on the carrier and region.
5G: 5G networks operate in both sub-6 GHz and millimeter wave (mmWave) frequency bands.
- Sub-6 GHz Bands: Include frequencies around 3500 MHz (n78 band) and other mid-band frequencies.
- mmWave Bands: Include extremely high frequencies, often above 24 GHz, such as 26 GHz and 28 GHz, and 60GHz.
- Meters to measure EMFs in the mmWave bands are available, but more expensive and usually limited to telcos or professionals.
