For some time now I have been concerned with the dangers of Wifi radiation, particularly on children. I currently use an old Buffalo wireless access point with DD-WRT firmware tweaked to lower the radiation and set to switch off at night. It is plugged into our BT Hub which has its super strong Wifi switched off (and BT Wifi disabled so it is truly off). Unfortunately, the really strong BT and Sky Wifi signals from our neighbours still affect our home a little, but at least I have reduced the radiation quite a bit.
With the new Raspberry Pi 3B+'s improved ethernet and Wifi speed, it could be a great Wifi hotspot which I presume could be set to run in a safer way (see https://www.jrseco.com/pcat/low-radiati ... 007ae3e449). These Eco-wifi routers claim to reduce radiation by 90%. I am sure that the RPi3B+ could be tweaked to run in a similar way by someone who knows how to do it...
Does anyone have any input on this? Imagine being able to make a low radiation wifi hotspot for under £35 (if you have a spare MicroSD card and suitable power supply lying around). It could be set up as described in MagPi issue 67 (Pi Security), but with added Low Radiation / ECO features.
