Protest against Wi-Fi

Wi-Fi is very damaging to health. The most common frequency used, 2.4 GHz, is very biologically active, and the radiation penetrates the blood-brain barrier in as little as ten minutes. That's not good for your health, and it is especially bad for children, whose bodies are still developing, Wi-Fi should not be allowed in schools, public places or public transportation; there must always be a Wi-Fi free alternative for those of us who don't want to be irradiated. Landlines and wired connections are both safer and cheaper, so why do we need Wi-Fi? Please note that the "Multilingual Say No to Wi-Fi" products are templates. You can change the message above and below the "No Wi-Fi" symbol to say anything you want, in any language you want. You can also make the symbol bigger or smaller.
