I think the point was more that a cellular modem is not easily controlled or
detected. An ordinary modem requires the use of a phone line. This can be
easily controlled with digital phone networks for the voice phones on the
desks and no analog lines available. A cellular modem cannot be so easily
controlled.
I see the modem issue itself as more of a dressed up version of the same old
problem no technology can ever address: internal malicious users. If
there's a trusted employee that's bent on getting information out of the
office, it can happen. A worse-case scenario might be somebody jotting down
notes with a pencil of what they see displayed on a monitor. Are you going
to implement a policy of strip searches to check that nobody has stuffed
notes into their underwear on the way out? I guess it depends on what
you're trying to protect and how important it is.

What is the significence of a cell phone modem to this topic. Or to put
it another way, other than not having to rely on a land line, what can a
cell phone modem do that a ordinary modem can not?
My apologies if this is a really stupid question.
