First a modeling of the downlink capacity is given which allows determination of the relationship between the signal to interference ratio and required downlink power per user. In the second part, following a similar methodology to those presented in Sipila et al. (2000) and Hiltunen et al. (2000), an average approach to estimate the total Node B output power according to design and capacity requirements is presented This method is based on assumptions, which could differ from real network situations. Therefore in a third part, the difference between the previous average approach and extended simulations is studied in different cases: mobiles are randomly drawn in the cell and parameters such as orthogonality and frequency reuse factor are not constant. It is shown that Node B power, at the Node B antenna connector, determined by the average approach is not enough to guarantee desired capacity. This comparison leads us to define margins, which are mandatory to ensure the capacity with the required quality of service (QoS).","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference.

Traffic characterization can be done in two steps. In the first step the applications that use network resources are identified, as well as the percentage of time they are active. The second step describes the traffic generation pattern of an active application. In this work we analyze network traces generated by four Internet game applications in order to characterize their traffic generation pattern. This characterization is achieved by obtaining a statistical description of different parameters associated with a traffic model. The model is shown to be robust, that is, the parameters of the model can be characterized using the same probability distributions independent of the application. It is shown that the gamma and uniform distributions can be used to characterize the random parameters of the model. Observed values of the parameter moments are presented.","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat.
