The most serious conundrum is RF is so ubiquitous that litigation of and changes in the school
will not solve this if it was real. All the new phones worthy of buying have dual band WIFI hardware, bluetooth,
and a gazillion cell service bands.
Unknown and rejected by the tinfoil hats is the reality that more and closser Cell, WiFi towers and
routers is the only way to enable dynamic systems to operate at lower power levels. The further
away a modern router is the more power a phone or laptop must use to hold up the near end
of transmission pair.
WiFi inside of aircraft... WiFi in coffee shops, WiFi in grocery stores so the stock clerks can
scan and check a gazillon items an hour and via wifi send the data back to the home office three
time zones away. WiFi in an aircraft is interesting... the aircraft would reflect in inside the cabin
and even at low antenna power the RF noise could be a thing.
My guess is the parents of this child put their cell phone in the kids stroller...
and continue to use their devices in the automobile and more.
I would love this to go to court and the judge slam the heck out of the first plaintiff attorney
that flips open a laptop and connect to the courthouse WiFi in the presence of the child.
If their child has a true problem and they have not moved to one of the rare almost RF free
locations the parents need to be relieved of the child by child protective services.
I worry about this too but the risk of a broken leg after tripping over yet another wire
is a bigger risk AFAICT.
