Tips for travellers with EHS
After a rough selection of suitable accommodations before booking travelers with EHS (electrohypersensitivity) should of course also call on site and inquire about the current conditions (DECT, mobile phone etc.).
Depending on the sensitivity, it may also be advisable to consult an overview map with transmitter locations in advance. These are available e.g. for
Cellular network in Germany
LTE coverage in Germany
Mobile radio locations in Austria
Mobile radio locations in Switzerland
Mobile radio locations in Italy
Public Wifi in Russia
Mobile radio locations in Canada
Shaw Go WiFi-Hotspots in Canada
Wifi sources worldwide (research community)
Mobile phone reception worldwide (based on user data of the Opensignal app)
By the way
DLAN or PowerLAN (PLC), in which data is transmitted via the domestic power network and which often is considered harmless, is no real alternative to WLAN - not least because it modulates higher frequencies onto the originally clean 50 Hz sine curve of the power network and by this (just like other sources) creates the so-called "dirty electricity. Only a Local Area Network (LAN), i.e. data transmission via separate line connections, is a healthy alternative to WLAN.
