>>>And then the signal is weak, I'd guess, so some shielding of the cable and the case would require much more sensitive equipment? Also, how does that work on laptops, the signal can be even weaker and the cable is twenty times shorter - less of an antenna, I'd say.

>>Well, after we have learned about Iridium and how they get information out of the noise I would be more paranoic. Weak signals are a matter of math rather then of amplifying. And the flanks of digital signals are nice.

>>By the high frequencies used in the comp and there digital nature (what ends up with even higher frequencies, look up fourier transform on rectangular function) shielding is very tricky. One CD tray out of plastic or a badly connected socket is enough. Cooling fans are a problem too.

No NO NOOOOO
I'm not allowed to buy tinfoil anymore. Book keeping will freak out. Under EU law this is dealing with unprocessed ignoble metal. It raises endless tax problems.

And it needs very carefull work. A bad connection or a small opening could make things worst. We are talking of a wave lenght of what 10 cm what means 5 cm max slot and the sidebands are even smaller. Try to shield a CD tray.

And Iridium is around 1,5Ghz. Look at the power output there. And they can transfer data, not only low rate keystrokes.
