ABSTRACT

In recent years, Broadband technology has rapidly become an established, global commodity required by a high percentage of the population. The demand has risen rapidly, with a worldwide installed base of 57 million lines in 2002 rising to an estimated 80 million lines by the end of 2003. This healthy growth curve is expected to continue steadily over the next few years and reach the 200 million mark by 2006. DSL operators, who initially focused their deployments in densely-populated urban and metropolitan areas, are now challenged t ....etc

ABSTRACT!!!!

Abstract. The term WIMAX (Worldwide Interoperability for Microwave Access) has become synonymous with the IEEE 802.16 Wireless Metropolitan Area Network (MAN) air interface standard. Filling the gap between Wireless LANs and wide area networks, WIMAX-compliant systems will provide a cost-effective fixed wireless alternative to conventional wire-line DSL and cable in areas where those technologies are readily available. The WIMAX technology can provide a cost-effective broadband access solution in areas beyond the reach of DSL an ....etc

Introducing DWDM
The following discussion provides some background on why dense wavelength division multiplexing (DWDM) is an important innovation in optical networks and what benefits it can provide. We begin with a high-level view of the segments of the global network and the economic forces driving the revolution in fiber optic networks. We then examine the differences between traditional time-division multiplexing (TDM) and wavelength division multiplexing (WDM). Finally, we explore the advantages of this new technology. ....etc

Introduction
LAN forms basis of all commercial,research,and data communication networks.Recently an increase in applications demand significantly higher band width. Ethernet is an easy to understand and extremely cost-effective technology. For these reasons, 98% of local area network (LAN) connections are now Ethernet based.
To meet this,high speed LAN types have been developed ,including a number of variations of basic ethernetLANs. CSMA/CD(carrier sense multiple access with collision detection) is used widely in ....etc

ABSTRACT

Todayâ„¢s global communications infrastructures of landlines, cellular towers, and satellites are inadequately equipped to support the increasing worldwide demand for faster, better, and less expensive service. At a time when conventional ground and satellite systems are facing increasing obstacles and spiraling costs, a low cost solution is being advocated.

This seminar focuses on airborne platforms- airships, planes, helicopters or some hybrid solutions which could operate at stratospheric altitudes for significant period ....etc

FIXED AND MOBILE WIMAX

ABSTRACT

Within the last two decades, communication advances have reshaped the way we live our daily lives. Wireless communications has grown from an obscure, unknown service to an ubiquitous technology that serves almost half of the people on Earth. Whether we know it or not, computers now play a dominant role in our daily activities, and the Internet has completely reoriented the way people work, communicate, play, and learn. However severe the changes in our lifestyle may seem to have been ov ....etc

INTRODUCTION

From its origin more than 25 years ago, Ethernet has evolved to meet the increasing demands of packet-switched networks. Due to its proven low implementation cost, its known reliability, and relative simplicity of installation and maintenance, its popularity has grown to the point that today nearly all traffic on the Internet originates or ends with an Ethernet connection. Further, as the demand for ever-faster network speeds has grown, Ethernet has been adapted to handle these higher speeds and the concomi ....etc
