1) INTRODUCTION
Marconi's innovative perception of electromagnetic waves and the air interface in 1897 was the first milestone on the important road to shared use of the radio spectrum. But only after almost a century later did mobile wireless communication start to take off. Despite a series of disappointing false starts, communication world in the late 1980's was rapidly becoming mor ....etc

Security for the Third Generation (3G) Mobile System


1 Introduction
When considering security in mobile systems, in common with most other systems, our main
objectives are in preventing:
Access and use of service to avoid or reduce a legitimate charge.
Loss of confidentiality or integrity of a user s or operator s data
Denial of a specific user s access to their service or denial of access by all users to a service
However, user expectations for instant communication ....etc

Improving TCP/IP Performance over Third-Generation Wireless Networks
The (3G) wireless networks with high data rates is gradually being deployed. The Transmission Control Protocol (TCP) must be optimised to perform in these networks. This will have a broad and significant impact on data application performance. The parts described in this chapter are :
-adapting to the significant delay and rate variations over the wireless channel and
-a wireless channel and TCP-aware scheduling and buffer sharing algorithm
Window Regulator algo ....etc

Abstract
The third generation(3G) wireless network is envisaged as the next generation wireless solution for meeting the demand of its users. It promises to provide wireless access to multimedia applications at rates upto 2Mbps. But the problems of intermittent disconnection, high error rate in wireless networks can cause degradation of protocols and compromise the QoS (Quality-of-Service) guaranteed to the users. So, there is a need for adaptive protocols, which, on determining the current adverse wireless network conditions, adapt th ....etc

seminar report on third generation solid state drives pdf

Abstract
The explosion of flash memory technology has dramatically increased storage capacity and decreased the cost of non-volatile semiconductor memory. The technology has fueled the proliferation of USB flash drives and is now poised to replace magnetic hard disks in some applications.

A solid state drive (SSD) is a non-volatile memory system that emulates a magnetic hard disk drive (HDD). SSDs do not contain any moving parts, however, and depend on flash memory chips to store data. ....etc
