Vista - If I disable the WIFI card from the device manager, is it truly off?

If I disable the WIFI card from the device manager, is it truly off?

My concern is the Electromagnetic energy that these cards put off...

new studies show that the amount of energy recieved from the user of a
laptop is very similar
as if you are using a cellphone, because it may be further away than a
cellphone but the duration of use is higher as well
as the frequency of the waves are lower thus they are being absorbed at a
higher rate by the body.

I am talking here about desktop computers with cards, but I would also like
to know if this applies to LAPTOP.

There is increasing concern about the negative effects of the EM waves...

I dont want to debate if there is danger or not since I posted this question
one time again in the past in another newsgroup
but only got wiseguy argumentive or joke responses and no one knew a real
answer.
If you dont know the answer to the question refrain from posting
your own theory about this phenomena please... and no tinfoil jokes please.

This is a serious matter.

so if I disable it from the device manager is the antenna truly off 100%?


THANKS

microwave radiation from mobile phones and other wireless devices is safe.
The early research saying otherwise has been largely discredited.

Please tell use more about other things in the modern world that you shield
yourself from. Are you a Mormon by any chance?

I meant Quaker!

Sorry to call you a Mormon. They are just a bit too weird.

my question is for a hospital with disabled kids
that they will be given a charity with laptops, they will have lan cables
and wifi but it would be good to know
if turning on and off the wifi would reduce their exposure

some are under 10 and some are very sick

any more awful mean comments?

In short, maybe. To be sure, pull the card out.

If you're worried about the RF from WiFi, you'd better also take the
batteries out of your cordless phones, don't use the microwave oven, ditch
your cordless mouse, and beware of many other remote controls - some are
infrared, some use the same 2.4GHz band as all the above.

Your answer is No.
The waves are still there regardless if your card is receiving them or not.
WI-FI works just like cell phones and other devices. When their on they
receive signals and decode them. Think on a lesser scale, if your FM radio
is setting beside you and is off, does that mean there is no signal? of
course not. I wouldn't be to concerned one way or the other and don't think
it's written in stone that these things are dangerous. In other words, don't
sweat the petty things and don't pet the sweaty things :>)

"RF Switch type definition:

*Hardware:
A Hardware RF Switch is a switch or toggle button that works by itself and
doesn't need a kernel driver or userspace application to make it work.

*Software
A Software RF Switch is a switch or toggle button that requires a kernel
driver or userspace application to make it work. Some laptops may not have
a specific switch/button but still have the hardware part that controls the
wireless radio state and can still be made to work with software."

The Wifi consists of two parts, Rx and Tx. Rx is the receiver, and the
receiver is listening for Wifi signals from other devices. The energy
level of those other devices would be small, due to distance and attenuation
by walls etc.

The other part is Tx, the transmitter. I cannot find enough info about the
transmitter, to be able to tell you whether it is continuous, or is only
activated when packets are being sent (i.e. whatever protocol is needed to
keep Wifi sessions active). But if you think about it, there are limited
channels, and the channels must be time shared, or otherwise few devices
could share one access point. The implication is, that the transmitter
probably is not active continuously.

Since you are serious, I see two alternatives.

1) Open up the laptop, and unplug the Wifi module. Simple and guaranteed.
2) Open up the laptop, and disconnect the antenna(s). Find and purchase
terminator plugs. This would consist of a resistor, mounted inside a
connector with metal cap. Since the antenna connectors in laptops are
tiny, this project is something you might not want to try yourself.
But if the Wifi is integrated onto the laptop motherboard, and is not
a removable module, then this technique could be an alternative.
The terminator plugs are important, as they convert the RF into heat,
and the resistor impedance has to match the rest of the RF setup, so
there are no reflections. That is better than just trying to short
the thing, which may not yield the results you'd expect.

(In the picture here, you can see how tiny the connectors are, for the two antennas)

In the first alternative above, there is no need to check whether it is
working. In the second case, you may want to use an external device,
to verify that the "surgery went well".

3) Use a software means to disable RF output. That means, not disabling
the device in Device Manager, but leaving the driver installed. Then,
you use software, to put the radio state in a disabled mode. That is
more deterministic than disabling in Device Manager, and not really
knowing how clever the hardware is. I note in the description of one
Wifi MAC, that it has a processor and firmware in it, so is an
autonomous subsystem. While it could start out, after reset, in a
benign state, I don't know that for sure.

In (2) and (3), you need an external means of determining whether it worked
or not. On the one hand, the market is saturated with cute little Wifi
chips inside a "detector", which is a protocol specific way to measure
RF energy. But if you want to survey the area you are in, for non-specific
RF, then a device like this might be handy. Unfortunately, the
devices I could find here, don't go all the way to 5GHz. For example,
maybe the following device could also detect a leaking microwave oven.

mobile phones and wifi each side is a transceiver (transmitter and
receiver). So they do give out microwaves, but scientists have now found,
after many years of research, that they are harmless in these low levels,
even when held up to your head for long periods.

You missed my point about the Radio bit :>)
Just because the Radio is not on doesn't mean the waves are not around you.
Like if a tree falls in the forest and you know the rest :>)

As they said, if EM waves concern you, you'd have to turn off your router,
if you're connected wireless, and ask your neighbors to stop using wireless
technologies. The radiowaves exists, if you receive them or not.
And to add informations, if you've got an R/C toy, or a son who has one,
you'd get the same amount of radiations.
Yes, the antenna should be off, or at least not picking up waves, very much
the same way a shutdown cellphone stops picking up the bulk of the EM waves
or a TV without an antenna picks up only noises.
But no, you'd get exposed to the same amount of EM radiations, if you've
still got a router in the house. Or in the neighbourhood.
