Well I ment more in terms of some Roms actually have the tx and Rx power turned up to give the WiFi better distance and signal strength, technically WiFi and signal should be close to one another, being as both most likely have a module that need power and an antenna, just the searching over and over effects it which 3g/LTE will do all the time looking for towers, for me as an example I can't leave WiFi on my phone, I'm in a strange location where about 12 WiFi connections will be detected lost, detected, lost over and over my device become like 80 degrees if I forget and leave WiFi on at home for more then 30 minutes
My house has really thick walls, so much in fact that my WiFi isn't available even right out front of my house, but my last device had a ROM which increased the power and I could get my home WiFi almost 3 blocks away, downside was it drained the battery in less then 10 hours lol even tho the phone itselfs best charge only last 24 it was a huge difference of 14 hours on the one that played with antenna power
You can also do the same with custom firmware for your router but the router will get hot a lot quicker due to all the extra power its using
