Open Source Baseband Firmware for 2G Cellular Networks

Short Description

GSM/2G is the most ubiquitous mobile communication standard worldwide. Millions of people use is every day. Recently, a state-of-the-art Mobile Station (MS) Physical Layer (PHY) for GSM, GPRS, EDGE, and Evolved EDGE has been completed in the RazorEDGE project. An FPGA testbed with analog and digital signal processing blocks of the PHY is available. It uses the ML605 board from XILINX [cite] and the evalEDGE FMC module for analog processing. As this testbed support only PHY operations a separate board with a CPU is required for baseband firmware. The [Baseband Meets CPU] project implement the PULP CPU next to the digital signal processing blocks on the ML605 board. However, there is no complete and open source baseband firmware availble for 2G operation.

In this project the source code from Open Source GSM Phone Call and the hardware from [Baseband Meets CPU] shall be taken to roll-out an open source baseband software project with support beyond voice calls. The firmware shall be based on OsmocomBB. A protocol tester [cite] or OpenBTS [cite] can be used to test the baseband firmware.
