I gather that "firmware" is generally what provides the baseband services?
Sorry, the phone world is still very foreign to me. I realize these questions may sound silly, but I'm slowly piecing all of this together.
- fsflover 5y agoPinephone modem runs its own OS inside. So if you have a Pinephone, you run two Linux'es at the same time: normal OS and the one on the modem. The core of modem responsible for the actual connections to the towers is closed though AFAIK.
- seba_dos1 5y agoThat "firmware" which is being replaced by open equivalent is a GNU/Linux system prepared by Quectel running on the modem itself and providing services like AT command or audio routing daemons. The actual baseband-y stuff is done in Qualcomm's DSPs which stay as closed as ever.
