Low Earth Orbit Satellites (August 1998)

"...tiny micro-satellites flying in low orbt and receiving all the transmissions from industry, that is: data communications between handheld computers  to their main computers, internal mobile phones and so on.

Everybody thinks you only need to protect your signals to what is outside on Earth, no one cares that all signals also go up to sky.   A  specially constructed micro satellite can receive such secret information for  industrial espionage."
