Thread: Is This A Scam ? (cell phone/bluetooth protection)

Came up with this website here, which claims that the health effects are indeed precarious, and offers a solution for $$. I think this is a scam but who knows ?

Mostly this is food for scam artists.
There is no good evidence that phones or bluetooth devices are a hazard.
My reading of the web site finds technical tomfoolery that gives me pause.

Bluetooth devices are much lower power than phones so bluetooth is "better"
than a phone along side your ear. If you are on the road and talk a lot an over
one ear wired head set is better still (truck driver, salesman on the road).
A bluetooth device in the car itself or on the sun visor is very handy.

The largest risk is the distraction the durn things give drivers.

On the flip side, bluetooth devices are always transmitting, even if there is no phone conversation. So long term the EMF dosage might be higher.

Phones are constantly in contact with the towers. Most importantly they
will often attempt to connect towers that they will never use only to find that
the transmitter must be run way up. If you happen to hang out in a marginal
service area (most of Silicon Valley, CA) the phone is always searching for
a better tower.

So you may be correct yet other individuals in others service areas will
have another view of the issue.

Of interest the local g'vment has begun embracing mini towers that can
be bolted to common light and power poles so in a year I may have
a different view of it all from my phone.

Of interest BlueTooth device use astoundingly low power levels.
In some cases the bluetooth levels can be 1/100th of cell phone
levels. Since power is reduced by the square of the distance
moving the phone itself to arms length has a big power change
and since water is a big cell phone problem moving from two inches
from the old wet brain to three feet away helps the phone so it
can operate at lower power and also reduce power to the old
wet noodle by perhaps 256 or more. Moving the phone itself
from 2" to 6' is a reduction change of 1024 fold.

Some Bluetooth receiver front ends are sensitive down to fempto watts
which boggles my mind.
