Is Cell Phone Communication Secure? According to a 2010 survey by the CDC (Center For Disease Control) 26.6% of US households use only cell phones at home (Blumberg). With such a large amount of people depending on cellular for communications it is important to understand the security risks they face. Cell phone communication is not completely secure but the risk depends on a variety of variables, user habits, interception points, and user vigilance. Legally no one is supposed to listen

Automatic Frequency Planning and Optimization Algorithm for Cellular Networks Muhammad Umair, Waleed Bin Shahid, Masab Javed Abbasi, Department of Electrical Engineering Royal Institute of Technology (KTH) SE100-44 Stockholm, SWEDEN E-mail: mumair@kth.se, waleed.shahid@mcs.edu.pk , masab.abbasi-pc@telenor.com.pk Abstract— Frequency planning in ever growing cellular networks is an extremely arduous task. Any effort to lay down manual frequency plans promulgates inefficiency in the cellular

Chapter 1. INTRODUCTION 1.1. CURRENT SCENARIO In current scenario, various sensors of plant is connected to the PLC for the data communication and PLC is program such that it give controlling output according to the threshold value of sensors. In this if the value of sensor is below or above the sensor value then it gives the respective output. This output is nothing but the controlling output from the PLC which gives signal to controlling device like value or alarm

telecommunication company in the country. The telecommunication system has experienced unprecedented and phenomenal growth only since 1996, when the first private telecommunication company GrameenPhone was authorized by the government to provide mobile GSM services. Due to expeditious developments in technology, infrastructure, services, and legal framework in the ensuing years, the telecommunication sector has become one of the largest revenue generating sectors in Bangladesh with the annual average

NETWORK EVOLUTION in 3G / 4G Abstract: During the 20th century, the key technology was information gathering, processing and distribution. This total technology will depend based on the network systems. Which are nothing but grouping of systems that should be controlled by a server. In business and home applications, mobile users and in all social issues the networks are used . To enhance the benefits of these networks, we are introducing 3G systems. The aim of the 3G security architecture

has profoundly impacted our lifestyle.After a decade of exponential growth today wireless network is one of the largest industry in the world. At the time of wirtting this close to 1 billoin people subscribe to cellular service,close to 200 billion gsm short message is exchanged every year.In response to this growth, a number of universities and educational institute have started research in this field and teaching programmes from which a number of engineers and scientist are re-educating themselves

We humans have always been inquisitive about predicting a person’s activity even before the person does it. We have come in terms with the technology using which we can come up with quite accurate results. We are living in a world full of sensors, right from the mobile in our pockets to the video camcorder in the supermarkets. We can use all these different sensors to aid us in Activity prediction. Notable sensors using which we can accomplish this are video sensors, audio sensors and location sensors
