PageOutline = Welcome to the OsmocomBB project =

OsmocomBB is an Open Source / Free Software GSM Baseband software implementation.

It intends to completely replace the need for a proprietary GSM baseband software, such as * drivers for the GSM analog and digital baseband (integrated and external) peripherals * the GSM phone-side protocol stack, from layer 1 up to layer 3

In short: By using [wiki:OsmocomBB] on a compatible phone, you are able
to make and receive phone calls, send and receive SMS, etc. based on Free Software only.

Over the past 12 months, we've been making very good progress. Most of the hardware drivers have been
written, and a relatively complete layer1, layer2 and layer3 exist.

No work has yet been done on any sort of UI on the phone. The only user interface is a telnet-based
command line.

To get started, checkout the [wiki:PreliminaryRequirements] and then [wiki:GettingStarted]

This is the project page about our experiments (so far) only with phones based on the Ti [wiki:Calypso]/[wiki:Iota]/[wiki:Rita]
GSM baseband chipset. The main target is the [wiki:MotorolaC123]. For more supported phones, check below.

We originally intended to build an inexpensive GSM experimentation board built with/around that chipset, but right now
are pursuing a slightly alternative course by using cheap off-the-shelf feature phones and write custom software for it. * The [wiki:ProjectRationale] * The big [wiki:MasterPlan] * [wiki:AreasOfWork] -- What needs to be done and who wants to do it * Information about the [wiki:TypicalCalypsoModemDesign] * [wiki:Calypso] -- The HERCROM digital baseband chip (DSP+ARM7) * [wiki:CalypsoDSP] -- The DSP inside the Calypso DBB * [wiki:Iota] -- The TWL3025 analog baseband chip (ADC/DAC) * [wiki:Rita] -- The TRF6151C GSM transceiver (VCO, up/down-conversion) * Information about the [wiki:SciphoneDreamG2], a [wiki:MT6235] based phone (not supported!!) * Old/obsolete plan/spec of the [wiki:GsmDevelBoard] (note: This project is on hold right now! * Description of our own GSM Stack * [wiki:L1A_L23_Interface] -- How the Layer1 interfaces with Layer2 and Layer3 of the stack * Notes on the [wiki:TSM30Layer1 TSM30 Layer1] as it can be found in the TSM30 source * [wiki:Glossary] -- The weird terms used in the phone baseband world * [wiki:LegalAspects] -- Important legal aspects of this project * [wiki:People] -- The people behind the project * [wiki:PressCoverage] -- What the press is writing about us
