To WiFi users.
Do you reduce your router’s WiFi Transmit Power to the bare minimum as required by you?
- Do you just keep it at the default 100%
- Did you not know you could reduce it (until now)
- Are you not able to control “your” WiFi router because it’s the ISP provided router and they didn’t give you the password?
- Do you actually require the 100% !?
Relative power? A phone and an app that shows you the received signal strength. Wifianalyzer on F-droid for example.
For me, setting it from max power to 6% (lowest value) took it from -30dBm on my couch to -50 dBm, so 20 dB difference, which is ca. 1/100. So it roughly checks out.
Keep in mind that radio waves are magic, and the higher in frequency you go, the darker the magic gets.
Absolute power is hard, especially if you are interested in average power for, like, health concerns. WiFi works in short bursts over a pretty large part of the spectrum, and you’d need calibrated equipment as well. I knew a guy who did radio wave strength mapping for like government, telcos and concerned residents, and he had a car full of tech. Simple field probes can be reasonably priced, but you need to know how to operate and interpret them.
People getting isekaied: Me gonna get that magicks!
But we have Magic at home! Also Black Magic!
