Smart meters
These are utility meters that use RF to communicate
with the supplier. Some are connected in a “mesh”
network and communicate frequently. Some use a
Mobile Phone network and transmit less often.
Some (e.g. Linky) use Power-Line Communication
(low frequency RF) and create a lot of “Dirty
Electricity” (DE).
Other sources
The AM11 can measure any RF EMFs between 200
and 8000 MHz. This includes (but is not limited to):
Mobile Phones & Phone Masts: 2G (GSM, CDMA), 3G
(EDGE, GPRS, HSPA), 4G-LTE, Low- and Mid-band 5G,
TETRA, Wi-Fi bands 802.11A, B, G, N at 2.4 and 5 - 6
GHz, Wireless-enabled laptops, tablets, and PCs
WI-MAX, Bluetooth & BLE, UHF RFID readers
Zigbee, Z-wave, and other IoT device protocols
Internet of Things (IOT) devices, fitness trackers,
Wireless burglar, fire and security alarms
Extremely strong signals below 200 MHz
The AM11 does not measure the following
This is because they do not radiate RF EMFs.
Dirty Electricity, Smart Meters that use PLC,
Near-Field Communications (NFC)
House wiring, or Power-frequency magnetic or
electric fields (Our PF5 meter will measure these)
Passive UHF RFID tags LF/HF RFID & shop safety tags
GPS receivers
