Wireless Systems in Developing Countries

The technology is among the important tools for sustainable development in the world. The way is spread in various countries is somehow dissimilar according the economic resources of each country. It is for that reason our work focuses on the use of technology in different countries with a particular attention to developing countries. The technology on which we underscored is wireless system, as emphasized by many examples is nowadays more used than wired system thanks to its advantages in deployment and utilization. In order to analyze how wireless systems are used in developing countries certain methodologies are adopted. At first sight, the current use of wireless systems in developing world is shown with the aid of a table. Above all, we have also considered the architecture of wireless systems where through a project aimed to make intelligibility tests an architecture is designed and implemented with wireless equipments. Among the principal methods for the transmission of data in wireless systems, the multicast transmission is analyzed with greater interest through the protocols and algorithms most important. This study suggests that the multicast transmission makes better use of wireless systems. Taking into account the best utilization of wireless system, it is obviously clear that this technology would not be well utilized and exploited when the frequency is not well managed. Therefore, a study concerning the spectrum management, spectrum cost and methodologies applicable in both developed and developing countries is carried out which further availed to suggest a better frequency utilization in developing countries. At the end of this work it is observed that the use of wireless technologies is moving forward rapidly in developing countries as indicated by the rapid growth of mobile phone users and other wireless technologies. The implementation of new technologies is easier in these countries as it does not require an upgrade from old to new technologies which sometimes seems impossible or demands expensive and a lot of work. Several conclusions are then drawn for particular cases.
