Communication Question

1. Turn the receiver off.

2. Turn the volume down.

3. Install copper screening around the "certain area". See "Faraday cage".

4. Don't be so paranoid.

5. Give some useful information.

6. Demolish the area.

for a certain place within a cell that should not receive any signal ..........????

Install copper screening around the "certain area". See "Faraday cage".

Why do you ask?

7. Turn the transmitter off.

This has to be a first!!!

I'm always bitching about not having reception and this guy want to turn it off?? I must be living on the wrong side the World?

A tight beam to the intended receiver while using a simple time-division encryption circuit. That should do it.

Lyn is right, you can go Faraday Cage, but other less costly options may be effective if properly designed for the specific problem in question - you need to provide more details.

In order to be an effective obstacle to an incoming signal, the design spec of conductive elements in a shielding device is that the length must be at least 1/10 of the wavelength of the signal in question. So first tell us, what is the frequency of the signal in question, or the range of frequencies you want to block. There are numerous shielding products on the market, including conductive paints and fabrics, and depending on the metals or conductive materials used and the design, different products are also best for specific frequency ranges. What is the size of the area that you want to isolate? Is the problem signal directional? You need to provide these details too, for appropriate solutions to be proposed.

I'm not wasting any more time here.

This information can also be used for illegal purposes. Like preventing a certain area/person/bank/jail from transmitting the signals.

exactly what i need superji superji superji.......

Exactly what you need? Really?

Which part: The undefined 'Signal Blocker' or the guy in the cell?

This thread creeps me out!

What the crap is "superji", and thanks Fredski for providing a basket for the OP.
