UMTS networks are currently being deployed and upgraded across the world. UMTS mobile phones are able to send and receive large amounts of data in a short time. The high data rates enable new services such as mobile TV, high speed Internet access, and video telephony. But there is a caveat: base station antennas have to be perfectly attuned to each other. Otherwise, the user might suffer bad connections and rather limted throughput. These unpleasant experiences can be avoided with the results from this project!

Radio network planning is about finding a good configuration for the antennas. This task is more difficult with UTMS than with previous radio technologies, because the system is more complex. In the present project, the challenge is tackled using mathematical methods. New mathematical models for radio networks have been developed that leverage high-end optimization approaches. By mapping the formulas and equations into specialized software that has been developed within the project, an optimal configuration of antennas can be found. Using the methods developed in this project, operators use their investment more efficiently, emission is reduced, and the customer enjoys a smoother mobile telephony experience.
