That is why in recent years have been marked by the rise of a revolution in computer networks and wireless systems. Combining connectivity and mobility, these new technologies are poised to fundamentally change the information systems and infrastructure. In this paper, we propose a next generation network for Algeria based on the IEEE 802.16 standard and its various technologies in order to minimize the number of antennas within the city and maximize coverage by connecting several cities together. KEYWORDS: Network, Cell, IEEE 802.16, OFDM. INTRODUCTION Currently, one of the challenges in the world of telecommunications is whether networks are able to meet certain requirements, will be on the basis wired, wireless or mixed ...? In effect, wired networks are more reliable when the wireless transmission of information is more likely to be affected by many external factors. At the same time, the deployment of a wireless link does not require civil works and their coverage areas are not related to the proximity of a tundish. In this paper we will first introduce the IEEE 802.16e standard and technologies included motivates us to use as a basic structure for our network. Then we describe our network model and the structure of its various components. Then the simulation of two Scenarios: the telephone and the Internet. And finally we show the simulation results and conclusion. IEEE 802.16E STANDARD This is a standard designed to provide access to broadband networks, urban size, taking into account the needs of users and applications in terms of quality of service (QoS), mobility and security. [1] Good speed and great coverage area (theoretically 70 Mbit / s over several Km) results are a combination of a set of techniques. The figure of this standard is shown as follows: R o a C e l C e l C e l A S N A S N A S N A S N B S M S N A P IP Ac ce ss Ne tw D H C P D N S A D H C P D N S C S N C S N N S P Int er ne t Int er ne t E xt er n Figure. 1.
