Brief Abstract:
|
|
|
|
Recent years have seen a remarkable increase in Free Software running on
|
|
smartphones. However, all such software is designed to run on the Application
|
|
Processor (AP) only. The actual GSM protocol stack and RF Modem drivers are
|
|
running as firmware on a completely different processor: The Baseband Processor
|
|
(BP).
|
|
|
|
OsmocomBB is a project developing the worlds first Free Software GSM protocol
|
|
stack for the mobile phone side. It includes the hardare drivers for one
|
|
particular GSM baseband processor chipset and replaces the vendor-provided
|
|
firmware on compatible chipsets/phones.
|
|
|
|
The presentation will introduce the challenges of doing this development in
|
|
the environment of the arguably most closed part of the semiconductor industry,
|
|
describe the software architecture and give a practical demonstration.
