5 | 6 | fixeria | [[OsmocomBB:]] project provides almost free software GSM mobile station implementation, from Layer 1 to Layer 3. The last non-free parts are: layer 1 and low level signal processing that are implemented in a non-free DSP software that is inside of the hardware platform that [[OsmocomBB:]] is currently based on (mostly reverse engineered [[OsmocomBB:TI_Calypso_Chipset|Calypso]] based mobile phones). |

7 | 6 | fixeria | The [[SDR PHY for OsmocomBB]] aims to replace these non-free parts through use Software Defined Radio devices and by creating missing software part for tasks such as voice encoding/decoding, channel encoding/decoding, burst modulation/demodulation and controlling SDR hardware. In order to achieve this goal the [[SDR PHY for OsmocomBB]] brings together [[OsmocomBB:]] and [[gr-gsm:]] projects, where the role of [[gr-gsm:]] is to provide GSM bursts transmission and reception with everything starting from channel coding/decoding being done in [[OsmocomBB:]]. |

9 | 6 | fixeria | Having support for general purpose SDR hardware has additional advantage of not being locked to a single and already obsolete hardware platform. Adding support for new well documented SDR platforms is significantly easier than reverse-engineering mobile phones hardware and software. This could sustain [[OsmocomBB:]] project's life even in the absence of hacked mobile phones it is able to run on. |
