This is some of the projects where I have been involved as the lead software designer. References are available.

  • WCDMA ACP (automatic cell planning) tool for a major telecom equipment vendor. The tool is given a network configuration, terrain maps, traffic data/demographics, and target KPIs (such as coverage and interference). It then proposes network changes (e.g. power, azimuth, and RET), together with geographical plots of the resulting radio environment. Air interface measurements are taken into account, if available. I did all implementation work except GUI, and specified the algorithms. This tool was built in a Java environment.
  • Multitechnology ACP for a major telecom software company. The problem domain is similar to the WCDMA ACP described above, but this tool supported multiple radio technologies, including LTE. The tool was implemented on the .NET/C# platform.
  • LTE measurement analysis tools used in some of the world's first commercial LTE network deployments. One of the challenges was to make reliable use of the sometimes unstable measurements from early LTE equipment prototypes.
  • Cloud-based 3D graphics rendering system, providing complex 3D images on demand to web clients. The performance requirements were challenging due to the need for on-demand rendering. I solved this with a combination of 3D optimization techniques and load balancing between multiple render servers. The system was built in a Java Servlet environment with native components, running on Amazon EC2 Linux servers.
  • Measurement conversion tool for a major European operator. The main complication was high performance requirements for massive data volumes.
  • WiMAX analysis toolchain (coverage/interference/capacity predictions).
  • GSM synthesizer hopping AFP (automatic frequency planner) for "ad hoc" planning, i.e. where HFS definitions are unique per site.
  • GSM traffic analysis tool (voice/packet). Prediction of parameters such as captured traffic, blocking rates, peak data rate, and sustained throughput for voice, (E)GPRS, and EDGE Evo.
  • "TCP/IP-handboken" ("The TCP/IP handbook"), the first Swedish book on the TCP/IP protocol stack, was written by me in 1996. It has been university course literature in Sweden, and was also translated to Finnish.
