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!

I've been looking into getting into phreaking. I'm definitely going to post something about this in future articles I write. Also, I look forward to checing out http://www.rabbit-hole.com

Smells like targeted spam to me. Honestly, why don't we enforce moderation on a user's first post?

So I let this post go by for a while without any notice, but I've recently got back on the bandwagon with finding out about mobile broadband.

With what tfwnoqt314gf1 said, it seems that the IMSI-catcher may be on the right page, but I want to make sure I have my basics down. Broadband is basically a WAN connection correct? It operates like Bluetooth or WiFi with set frequencies of radio waves correct? My question then is based around this: wireless networks are created from wired connections comming in from a modem, to a router that creates the WiFi network. In this instance, this is a personal wireless network, capable of being ferried only by mere tens-of-feet. But a broadband/cell tower generates a signal that can be picked up with any piece of hardware that's wired to the frequency. This is then a general public network distributed by acres of signal. Since this signal is available as stated, shouldn't it be possible to pick up the signal rather than hijack it from someone else? Just as a radio station can be encrypted (I don't know if it's true but it makes sense) and be received with the right equipment?

To restate, my question is then is it possible to either construct or modify a device that will pick up these signal and use that broadband signal to connect to the internet?

I'll be satisfied if this can't be answered but instead links or references are given for further research. I just want to make sure I'm heading in the right direction. I've found these pages so far:
http://en.wikipedia.org/wiki/Comparison ... _standards
http://en.wikipedia.org/wiki/3G
http://en.wikipedia.org/wiki/Mobile_broadband

Thanks, and any input is appreciated!

As a side note, maybe this can be accomplished with a phone with a modified OS that interprets the hardware reception of the signal as an open socket (like wireshark but for broadband)?

Okay, there's also this helpful link too (but I think it's a bit dated):
http://www.teach-ict.com/as_a2_ict_new/ ... eb/pg5.htm

-- Mon Oct 20, 2014 12:46 pm --

Hm... Maybe if not broadband internet, just being able to place calls or text would be nice (like doing HAM radio).
