Superiority The Use of WiMAX System on Wi-Fi System in The Iraqi Topographic

The high prevalence of the Internet services in Iraq have led to the emergence of tight and crowded towers Wi-Fi (Wireless Fidelity) services in residential neighborhoods because of the limited extent of coverage of this system.This led to increased cost of subscriber's services due to the multiplicity of mediators, as this system is limited only to cover the fixed places.In this research,we are compare the effectiveness in terms of coverage area (fixed and mobile ), speed downloading data and other matters.This system is WiMAX:(Worldwide Interoperability for Microwave Access).The WiMAX technology is well suited for cities characterized by the construction of a horizontal and a lack of natural heights or artificial (very high vertical buildings). This fully appliesto the Iraqi topographical, which will lead to lower the overall costs due to the reduction of the towers and equipment to a very small percentage. For example, Baghdad city will need no more than three towers for full coverage , in other hand technical specifications, lower cost to subscribers due to shorter preparation of mediators , reduced substations located in abundance in residential areas. Research will explain by direct comparison between the two systems including the strengths and weaknesses of both, and their behavior according to the topography of Iraqi cities.
