Wolf,
I agree with you whole heartedly about having unqualified labour installing electrical equipment. Not on my watch.
Here we use LAN freq. of 915 to 928 MHz with transmit power. Variable up to a max of a little less than 30dBm.
Modulation is FHSS. Transmitting every 4 hours of 350msec
When you consider a cell phone which transmits at probably between 300 to 500 times that output with polling rates of every 30 sec the Smart meters are equivalent power output of the key lock opener for your car.
Anyhow WiFi is an Australian invention so I cannot go dissing that
I am enjoying this discussion with an educated person as opposed to my everyday dealings with Mr Joe Punter who does not have a clue.
My employees are threatened and abused both verbally and physically because of misinformation being passed on through fearmongering media outlets.
I commend you on taking a stand and making a difference.
I hope that this exercise for you does not end as a Quixotic experience.
