Reading The GSM Beacon Carrier with OsmocomBB and stoneEDGE
GSM is the most ubiquitous mobile communication standard worldwide. Millions of people use is every day. Recently, a physical layer (PHY) implementation of the GSM mobile communication standard has been completed at the Integrated Systems Laboratory (IIS). It comprises a state of the art transceiver chip and a digital baseband on an FPGA. In the past few years, the open source community behind the OsmocomBB project  has implemented a relatively complete GSM protocol stack for a Mobile Station (MS). On the Base Transceiver Station (BTS) side, open source solutions such as OpenBTS  have been existing for a while. The latter is even in use in some commercial networks. In this project the student will combine the IIS PHY with OsmocomBB software to build a complete MS. Furthermore, a voice call capable BTS using OpenBTS should be set up. Eventually, the MS and BTS can be used to place a phone call to a regular Android phone. This project will take the student through exciting VHDL as well as C programming tasks in order to build the entire system.
