Smart Antenna Systems for Mobile Communications:Seminar Report & PPT

Seminar On Smart Antenna 

Global demand for voice, data and video related services continues to grow faster than the required infrastructure can be deployed. Despite huge amount of money that has been spent in attempts to meet the need of the world market, the vast majority of people on Earth still do not have access to quality communication facilities. The greatest challenge faced by governments and service providers is the “last-mile” connection, which is the final link between the individual home or business users and worldwide network. Copper wires, traditional means of providing this “last-mile” connection is both costly and inadequate to meet the needs of the bandwidth intensive applications. Coaxial cable and power line communications all have technical limitations. And fiber optics, while technically superior and widely used in backbone applications, is extremely expensive to install to every home or business user. This is why more and more the wireless connection is being seen as an alternative to quickly and cost effectively meeting the need for flexible broadband links.

The proliferation of wireless networks and an increase in the bandwidth required has led to shortages in the scarcest resource of all, the finite number of radio frequencies that these devices use. This has increased the cost to obtain the few remaining licenses to use these frequencies and the related infrastructure costs required to provide these services.
