A fully-free cell phone experience, no baseband required

Denver Gingerich

Free software users have been able to use laptops with fully-free software for several years now. However, using a cell phone in the same way is still impossible due to the non-free baseband firmware present in all cellular devices on the market today. But does the cell phone experience even require a baseband? In this session, Denver will describe how to achieve much of the cell phone experience (especially voice and SMS/MMS) using existing free software, as well as strategies for surpassing the range and reach of emergency calling and data on the cellular network.

This talk was presented at LibrePlanet.


LibrePlanet is the Free Software Foundation's annual conference. The FSF campaigns for free/libre software, meaning it respects users' freedom and community. We believe that users are entitled to this; all software should be free.


We do not advocate "open source".

That term was coined to reject our views. It refers to similar practices, but usually presented solely as advantageous, without talking of right and wrong.


Richard Stallman launched the free software movement in 1983 by announcing development of the free operating system, GNU. By 1992, GNU was nearly operational; one major essential component was lacking, the kernel.


In 1992, Torvalds freed the kernel Linux, which filled the last gap in GNU. Since then, the combined GNU/Linux system has run in millions of computers. Nowadays you can buy a new computer with a totally free GNU/Linux system preinstalled.


The views of the speaker may not represent the Free Software Foundation. The Foundation supports the free software cause and freedom to share, and basic freedoms in the digital domain, but has no position on other political issues.
