2 | 23 | laforge | = Welcome to the OsmocomBB project = |
3 | 1 | ||
4 | 23 | laforge | OsmocomBB is an Open Source / Free Software GSM Baseband software implementation. |
5 | |||
6 | It intends to completely replace the need for a proprietary GSM baseband software, such as |
||
7 | * drivers for the GSM analog and digital baseband (integrated and external) peripherals |
||
8 | * the GSM phone-side protocol stack, from layer 1 up to layer 3 |
||
9 | |||
10 | 57 | laforge | In short: By using [wiki:OsmocomBB] on a compatible phone, you are able |
11 | 23 | laforge | to make and receive phone calls, send and receive SMS, etc. based on Free Software only. |
12 | 1 | ||
13 | 57 | laforge | Over the past 12 months, we've been making very good progress. Most of the hardware drivers have been |
14 | written, and a relatively complete layer1, layer2 and layer3 exist. |
||
15 | |||
16 | No work has yet been done on any sort of UI on the phone. The only user interface is a telnet-based |
||
17 | command line. |

22 | This is the project page about our experiments (so far) only with phones based on the Ti [wiki:Calypso]/[wiki:Iota]/[wiki:Rita] |
||
23 | 32 | laforge | GSM baseband chipset. The main target is the [wiki:MotorolaC123]. For more supported phones, check below. |
24 | 8 | laforge | |
25 | We originally intended to build an inexpensive GSM experimentation board built with/around that chipset, but right now |
||
26 | 15 | laforge | are pursuing a slightly alternative course by using cheap off-the-shelf feature phones and write custom software for it. |
