1. INTRODUCTION

In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommuni cations and data networks. However, there are some unique problems in cellular networks that challenge their service reliability. In addition to problems ....etc

ABSTRACT

So far transmission errors have been described as evil entity in communication literature. Introducing error intentionally can save power and reduce interference. This has been proved by scientists Jik Dong Kim (South Korea), Sang Wu Kim (USA) and Young Gil Kim (South Korea). It is about combined power and error control in multicarrier DS-CDMA systems ....etc

Abstract


This paper outlines some of the technical challenges that must be met, particularly with respect to handset radio design, that will allow coexistence between Cellular and WLAN modes of operation. Various aspects of coexistence are considered, such as the demands of the RF architecture, interference issues, chip set fabrication and cost issues. Conclusions are then drawn as to the defining aspects of WLAN and Cellular convergence ....etc

The recent spat of daylight robberies at the jewelers has prompted us to undertake this project. This is a Research & Development project having commercial value. A typical situation in case of a daylight armed robbery is that miscreants enter the shop posing as customers, suddenly they brandish their guns and ask the shopkeepers to hand over cash and valuables. The phone lines are instantly cut and no one is allowed to leave the shop. There is absolutely no way to raise an alarm or contact the police. It is not even possible to take out a cell ....etc
