Capacity planning for IMT-2000 using long range dependent traffic

IMT-2000, the 3/sup rd/ generation mobile telecommunication system will provide various types of services to users. To properly plan investment, a traffic model for each service is an essential job for service providers. In this paper, we developed a traffic model for voice traffic and wireless Internet traffic, which will be the most popular services in IMT-2000. Under the assumption that the session length of data traffic follows a cut-off Pareto distribution, we propose a new method to calculate the required spectrum of IMT-2000 using a diffusion approximation. The resulting MMM (medium multimedia) downlink traffic at high density in a building environment is compared with that of ITU-R. The resulting spectrum using the proposed method is greater than that of ITU-R.
