Electricity companies use many different electricity meters, some communicate with mesh systems, others via mobile networks and some via the power grid (power line communication, PLC). They can cause "dirty electricity". This is high-frequency interference on the power system, which is very troublesome for those who are hypersensitive to electricity. However, interference on the power grid can be attenuated with an electrical filter. Some factors that affect the transmission power are the distance to the receiving station (usually a transformer in the vicinity), the type of antenna and the terrain.
In addition to the electromagnetic radiation coming from the AMS transmitter (AMS Automatic Measurement and Control), which most people seem to be concerned about, AMS meters are prepared for communication with "Smart House" solutions (HAN - Home Area Network). This is not part of the AMS standard installation and will be an optional additional module for those who want to have "smart" houses. Suppliers of so-called Smart House solutions will offer wireless or wired control systems. The wireless ones will primarily be based on WiFi, while the wired solutions are designed to communicate on the wiring network throughout the house and therefore send out control signals (2kHz to 250MHz) on the wiring network. These signals will be an additional stress factor in the 50Hz electrical field that surrounds all the wires in the house. This means that you will be in the house and exposed to a high-frequency signal that over time can affect your health.
If you have a new electricity meter, a so-called Smart meter, in a facade cabinet, you can put a shielding protection such as fabric, wallpaper or paint on the entire inside of the wall where the electricity meter is located. If you live in an apartment just above the electrical room where the electricity meters are located, you can cover the floor with our shielding foil SAFEBUILD A190.
If the meter is indoors, you can instead sew up a curtain of shielding fabric, e.g. our Steel-Twin to have as a shield for the meter's communication.
Installing an external directional antenna for GSM/DCS/UMTS/HSDPA/LTE to the electricity meter is good because the antenna ensures that the signal from the electricity meter ends up outside the home and the electricity meter's signal is directed away from the home. The electricity meter's power also decreases because it guarantees good coverage instead of a small antenna that sits inside the electricity meter and transmits inside the home. If an external antenna is installed, it is important that the antenna in the meter is disconnected so that it does not continue the beam. An electrician can be hired to install a directional antenna with the associated cable to a freely high position.
