| 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 | In short: By using [wiki:OsmocomBB] on a compatible phone, you should eventually be able |
||
| 11 | to make and receive phone calls, send and receive SMS, etc. based on Free Software only. |
||
| 12 | |||
| 13 | At the moment we are in an early but still very promising stage of the project. Most work |
||
| 14 | is still being done at Layer1 of the protocol, but there is quick progress! |
||
| 15 | |||
| 16 | This is the project page about our experiments (so far) only with phones based on the Ti [wiki:Calypso]/[wiki:Iota]/[wiki:Rita] |
||
| 17 | 1 | GSM baseband chipset. |
|
| 18 | 8 | laforge | |
| 19 | We originally intended to build an inexpensive GSM experimentation board built with/around that chipset, but right now |
||
| 20 | 15 | laforge | are pursuing a slightly alternative course by using cheap off-the-shelf feature phones and write custom software for it. |
