Ket : Mobile telecommunications are in a strong development. The total number of mobile subscriptions is reaching the world’s population all along with an exponential scale of the data traffic. However, there are countries still dominated by second-generation networks, which are not sufficient to follow this continuous growth. The purpose of this work is to develop a radio network planning design project for a third-generation network, based on the requirements of a real Alcatel-Lucent’s customer, which are related to coverage, quality and interference. Network configuration inputs and assumptions are presented, in order to perform services predictions with Alcatel-Lucent design tool. Initial thirdgeneration design is based on the already existing second-generation network configurations. Optimization processes had to be developed not only to optimize the network to have best fitted thirdgeneration configurations, but also to achieve the requirements of both Alcatel-Lucent and the customer. There are three optimization phases described in the project: tilt optimization, new sites proposal and power optimization phase. Electrical tilt optimization was performed to improve signal level covered area. Then new 3G sites were proposed within the already existing 2G only sites of the network, as the requirements had not yet been achieved. Finally, power optimization was performed, only in urban and dense urban areas, to sectors with low covered area. After all the optimization phases, it can be concluded that all the design project requirements were achieved
