A key issue for cellular operators is the planning or re-configuration of radio base stations (BTSs) for fitting user requirements and guaranteeing a suitable quality of service (QoS). Time-varying scenarios as well as different and variable user needs require flexible and fast planners easy to use. Towards this end, the combination of reliable models able to predict the actual coverage of 3G and 4G networks with computationally-efficient optimizers is of great intrest in order to automatically configure large networks and achieve optimal performances in terms of throughput, served users, and bandwidth re-use. |

Starting from models proposed in the literature, members of the ELEDIA Research Center have developed innovative stochastic radio planners able to deduce the optimal configuration of large 3G and 4G networks. Unlike standard planning tools, such approaches consider a set of requirements expressed in terms of communication traffic over the region of interest and they determine the corresponding optimal setup able to guarantee the required throughput. More specifically, the research activities carried out in this area have been focused on the development of ad-hoc Evolutionary algorithms and their integration with state-of-the-art coverage models in order to automatically plan the network configuration for large sites (several hundreds BTSs). |
