Changing Rooms

[Mark van der Eynden]

Rod's mention of changing rooms got to me.

All this hoo ha about people using Video phones in Changing
rooms.......

What if a changing room was enclosed in a 'Faraday Shield'?

Could an effective 'Faraday Shield' be made into 'wall paper' and
pasted on the walls of the changing rooms (and any other rooms for
that matter)?

QED?

Please send all royalties to me!?

Cheers,

** Cannot the image from the camera can be stored for later transmission
?

If not in all models surely with some.

Kinda makes shielding a waste of effort.

You one of those perverts, boy ?

Presumably a properly designed mobile phone handset
would just keep the MMS and send it when it could
talk to the base again, outside the faraday cage.

Yes, its not hard to ensure that a mobile phone
cant get a good enough signal in a particular area.

Happens all the time by accident in basements particularly.

Request denied. Your have been dobbed in to
the authoritys on your perverted behaviour tho.

I did mention that you're a moslem too.

PRecisely, i believe they are stored, and sending them is only an
option. Plus, what frequency do those thhings run at? what would the
amz perforation size in the shield be?

yeah, i can get my phone down a few 'reception notches' by covering
the antenna in my hands

I noticed in a paper somewhere the other day that phones have been banned in
public swimming pools cause the kiddy fidlers have been using them to take
happy snaps.

Ultra bright IR Spot lights to wash the picture out will work. until they
put IR filters on the lense

well the next thing is watch phones.
Being prototyped at the moment
(from the messages in comp.arch.embedded look for some of Lewin's posts).
Transmit via bluetooth or ir to other device.

you idea doesn't stop people saving the photos on to a device and sending them later.

Also blocking one frequency wouldn't work.
You would have to block all mobile phone and bluetooth frequencies.
And bluetooth has a range up to 100m depending on the device and antenna used.
Most phones and pda's have a bluetooth range of 10m.
Add on for computers and embedded boards up to 100m with small antenna.
Using directional antennas give around double that.

Having a door would defeat a faraday cage.
Or a more tunnel like entrance could act like a wave guide

Concealable digital cameras have been around for a long time now.

They dont need to be able to transmit the picture
by RF to be useful in that particular situation.

you idea doesn't stop people saving the
photos on to a device and sending them later.

In fact that would normally be automatic.

Also blocking one frequency wouldn't work.
You would have to block all mobile phone and bluetooth frequencies.

A faraday cage would do that adequately.

Doesnt stop them being sent after you have left the cage tho.

You dont need to bother with any of that with decent digital
cameras. Just take the pics, plug it into the PC after you leave etc.

Having a door would defeat a faraday cage.

Not necessarily with mobile phones. Plenty of places dont have
an adequate signal level inside them and they do have doors.

Or a more tunnel like entrance could act like a wave guide

Fantasy at those freqs.

Okay, so the photos can be saved for later trasmission.

What if we put a micro(nano?) cell inside our 'Faraday Shield' with
the following programming....

Phone registered in cell?
Ring it
Goto Ring it
(You get the idea)

That will force the mongrels to turn their phones off. As an added
bonus, if they don't, everyone in the room will be aware there is a
phone around.

I suspect cells have a 'call all' facility for emergencies and what
not, if so this would enable an even more stripped down cell to be
used.

Cheers,

And any decent electronic camera that has nothing to do
with a mobile phone at all can always be used instead.

Completely trivial.

Anyone wanting to get some pics of naked
flesh etc will just use a digital camera, stupid.

Pity it would be completely illegal and wouldnt work anyway.

Someone is absolutely guaranteed to dob you in to the ACA.

They dont.

Wouldnt achieve a damned thing, they'd just use a digital camera instead.

Wouldnt be hard to disable the mobile phone/camera
RF frontend while you're in the changing room either.
Just take the sim out would work just as well.
