| ABSTRACT : |
The last few years have seen a tremendous demand for wireless services. Service providers have to accommodate this rapid growth on their existing networks as well as make plans for new networks. Therefore, there is a need for a cell planning and frequency planning tools incorporating optimization techniques to assist RF engineers for initial as well as the future growth planning. This paper proposes an innovative approach for automatic frequency planning in both the new and an existing network. The new approach replaces the current tedious and inaccurate manual process, simplifies planning, and also reduces operational costs. In addition, this process makes use of powerful EA(evolutionary algorithms) algorithms, which can provide a near optimum solution.
Key words: AFP, evolutionary algorithms, GSM, Site selection, propagation models, link budget. |
