INTRODUCTION

With the rapid progress in telecommunications, more and more services are provided on the basis of broadband communications, such as video services and high-speed Internet. With worldwide fundamental construction of a backbone network based on optical fiber providing almost unlimited communications capability, the limited throughput of the subscriber loop becomes one of the most stringent bottlenecks.Compared to the capacity of the backbone network, which is measured by tens of ....etc

INTRODUCTION
Wireless communication is the transfer of information over a distance without the use of electrical conductors or wires. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). Wireless communication is generally considered to be a branch of telecommunications.
It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless ....etc

ABSTRACT
The basic problems of wireless access are that the available spectrum is too limited and there is great attenuation of energy.These can be solved by frequency reuse and by reducing the maximum distance from the terminal to the nearest base station.
Distributed wireless communication system (DWCS) is a new architecture for a wireless access system with distributed antennas, distributed processors, and distributed controlling. The basic idea is to flatten the tree cellular structure. With distributed antennas, syste ....etc

A Privacy-Preserving Location Monitoring System for Wireless Sensor Networks



Abstract:-

Monitoring personal locations with a potentially un-trusted server poses privacy threats to the monitored individuals. To this end, we propose a privacy-preserving location monitoring system for wireless sensor networks. In our system, we design two in-network location anonymization algorithms, namely, resource- and quality-aware algorithms that aim to enable the system to provide high ....etc

INTRODUCTION
The term wireless transmission stands for interchange of power, electricity, data or any other type of information.
According to the electrical point of view, transmission lines are used for transmitting power supply.
But there is a major risk of electrical hazards like short circuits, power failure, & breakdown of transmission lines.
So, we have ....etc

WIRELESS BATTERY CHARGING SYSTEM USING RADIO FREQUENCY ENERGY HARVESTING




INTRODUCTION AND MOTIVATION

Cellular telephone technology became commercially available in the 1980’s. Since then, it has been like a snowball rolling downhill, ever increasing in the number of users and the speed at which the technology advances. When the cellular phone was first implemented, it was enormous in size by today’s standards. This reason is two-fold; the battery had ....etc

WIRELESS BASED BANK SECURITY SYSTEM USING SENSORS.
ABSTRACT
Pyroelectric sensors are low-cost, low-power small components commonly used to trigger alarm in the presence of humans or moving objects by means of black body radiation, the use of an array of pyroelectric sensors can lead to extraction of more features such as direction of movements, speed, number of people and other characteristics. In this work a low-cost pyroelectric infrared sensor based wireless network is set up to be used for tracking people motion. A no ....etc
