Phone Data & Broadcasting...

Hello,

I have a few questions that I've been wondering for quite some time, but not to sure how to get a hold of the information; so I came here.
I was wondering: what exactly is the data that flies through the air to our phones, and how is it different from wireless internet? Could it be possible to "hijack" a signal from some carrier using a simple phone, or something similar to that? Could it be possible to pick up the base of phone signals with a wireless card on a PC? If all that's required is a SIM card, a phone, and possibly an account, it's the same thing as dial-up or internet (I believe), so could it be handled in the same way (in terms of exploitation)?
I don't know that much about how phone networks work, so I apologize if these questions seem naive. If anyone has any suggestions, or pointers to articles about phone networks, or any help on these ponderings would be greatly appreciated!

Thanks!

I assume you're referring to a cell phone?

A wireless, landline telephone can be picked up with a simple HAM radio. It's illegal in the US (and I assume other countries), but it's pretty difficult (if not impossible) to know if this happened.

For cell phones, it is possible: http://en.wikipedia.org/wiki/IMSI-catcher You can dig up the patent yourself and build one, but, depending on your experience with electronics, that could take awhile. Doing it is worth it, since you can then mass produce them no problem, and it's cheaper in the long run than buying one.

There's also this neat little thing: http://rabbit-hole.org/ pick up cell phone transmissions AND pilot a damned drone. If you can get it to airdrop beer to you then you have everything you need.

Some cell phone companies and manufacturers encrypt data transmission with RSA/AES/whatever.

Thanks for the reply!

It seems that the IMSI-catcher mostly deals with intercepting data. I was wondering if there was a way to do it without stealing someone else's data, unless of course that's the only way to do it.

So is what you're saying about the rabbit-hole thing is to strap an IMSI-catcher to a drone? Interesting concept.

Thanks again for the reply!

Smells like targeted spam to me. Honestly, why don't we enforce moderation on a user's first post?
Assume that everything I say is or could be a lie.
