This is an old revision of the document!
The aim of the project is to improve functionality of OpenBTS software. USRP hardware is quite expensive.But our friends PiSec Hackerspace have one and we have possible remote access. It would be a good idea to share it between more people. Hackerspace could be ideal place to do that.
Goals of the Project
Status and Plan
The project is currently in the active stage.
[DONE] gsmbox - 8 osmocom compatible phones in one box with only USB as I/O.
[DONE] Run Kraken so we will be able to crack A5/1
Tune utilities for data capture
Tune Kraken (speedup, hardware, …)
Current tarbal containing various script and modifications is here:
This tarball is provided “as is”, poor coding quality guranteed, etc, etc.
This shield is used in combination with FT4232HQMiniModule to attach 4 Motorola C series GSM phones to computer using 4 serial connections.
tip - TX, 2nd ring - RX, rest - GND
Standard 2.5 mm jacks are just too big ;(
When assembled, it should look somehow like this:
Basic idea is to put multiple (8) phones into 3,5“ HDD box.
Only one usb cable as interface.
design & make “holder” for phones inside the box (use rep-rap) ⇒ use smaller box.
remove filters from phones, so we can sniff upstream better
