چکیده
This paper proposes a novel constraint-based 3G network-planning model and a novel hybrid approach for optimizing the 3G network-planning problem. Computational results show that the model and the approach are more efficient than the mathematical model and the existing heuristics. Optimal solutions are always obtained for small and medium sized problems. The proposed hybrid approach can be an efficient tool for tackling a wide range of combinatorial NP-hard problems.

متن کاملUsage of mobile location techniques for UMTS network planning in urban environment
The paper addresses the use UMTS terminals for “probing” the signal level as a function of location for the purposes of network planning and monitoring. Potential UMTS location techniques are presented and the location performance of time delay and correlation based techniques is estimated by using impulse responses calculated by three-dimensional simulation techniques. The probing accuracy is ...
