North Denmark Region, Denmark
* 16 years total in telecom companies * Initial investigation of traces from live networks * Debug of C/assembler target code with emulator/debugger * Designed/programmed GSM idle measurement interface module for new platform * Ported various drivers to new platform Specialties: Embedded software, debugging on target, serial port drivers, GSM system knowledge, C, assembler, ClearCase.
* Integration and release of common files belonging to layer 2/3. * Integration of GSM part of layer 1 with layer 2/3 (Selection measurement, system information gathering, RACH transmit, channel assignment, data link establishment). * Hand decoding of air messages defined in GSM specs. * Use of CMD 55/CMU200 GSM tester. * Modification of interface layer between layer 1 and layer 2/3. * Use of software trace tool on layer 2/3. Trace of interface between layer 2/3 and layer 1, internal events and states in stack entities and BA and BBA tables. * Use of Lauterbach JTAG debugger on target. Debug of: start-up problems, data abort and erroneous code generated by compiler. * Use of ClearCase/ClearQuest * Attended 2 UMTS courses. Covered: physical channels, cell search, random access, paging, dedicated channel sync, packet access, high speed downlink packet access and channel coding and multiplexing.
The site developed 2G, 2,5G and 3G layer 1 software for ST chipsets for mobile phones. Site existed Jan 2001 to May 2003. * Hard coded a layer 3 scenario capable of doing GSM call on tester. * 1st project: Studied some GSM specs and redesigned and implemented lower parts of GSM layer 1 measurements software to fit a new platform. Studied traces and debugged various problems found in field test. * Debug of power down software * 2nd project: ported various hardware drivers to a new platform. Set-up of make system * Used ClearCase source code control system. * Used CMU200 GSM tester.
