Abstract
The main agenda of this work is to design advanced security with affordable and less complex system referred as Invisible Eye . In this modern era, property crimes are more predominant which necessitates developing an advanced security system.

It is a single camera based security system which is used to protect the valuables kept in room. This system can be used when slew around the room and recorded when it is alerted by the presence of any intrusion . Manager can only view the footage which was alerted on the presence of intrusion ....etc

Definition

During the past year, mobile and integrated fixed/mobile operators announced an increasing number of fixed-mobile convergence initiatives, many of which are materializing in 2006. The majority of these initiatives are focused around UMA, the first standardized technology enabling seamless handover between mobile radio networks and WLANs. Clearly, in one way or another, UMA is a key agenda item for many operators.
Operators are looking at UMA to address the indoor voice market (i.e. accelerate or control fixed-to-mobile substituti ....etc

TECHNICAL AWARENESS OF GSM MOBILE
Principle of Mobile Communication
Multiple Access methodology
The technique of dynamically sharing the finite limited radio spectrum by multiple users is called Multiple Access Technique.
Generally there are three different types of multiple access technologies. They are
Frequency Division Multiple Access (FDMA)
Time Division Multiple Access (TDMA)
Code Division multiple Access (CDMA)
Frequency Division Multiple Access (FDMA):
FDMA is a familiar method of allocating ....etc

Abstract
xMax, as a physical layer technology, can be configured for use in wired and wireless products; designed for deployment at any frequency; configured for licensed and unlicensed spectrum, or in a spectrum sharing fashion.

Importantly, it can improve range and battery life in such applications and uses the radio spectrum in a very power efficient manner. The original xMax system is a hybrid technology in the sense that it has aspects of both narrowband and wideband communication sys ....etc

Abstract
This work extends the study done in the area of Message Sequence charts(MSCs) towards the automation of testing including testing the design of a system.An al- gorithm used for generating the test cases from the design speci cation is also developed. Our work proposes an approach to generate test cases from a set of Message Sequence Charts (MSCs) by constructing a semantically equivalent nite state machine for testing reactive and embedded software. Test cases are expressed as a sequence of messages to be exchanged among various sy ....etc

1. INTRODUCTION
Code Division Spread Spectrum is one form of CDMA communication technique optimized for the cost conscious, high volume and short cycle consumer electronics market. Its primary application is in digital cordless telephony today. Meanwhile, it is being applied to wireless devices for the last 100-meter connection to the Internet, and in the wireless local loop to provide sub-$20 handset cost, tariff free mobile voice services in some third world countries.
Why is CD/SS technology suitable for consumer e ....etc

1.ABSTRACT
Wireless Intelligent Network (WIN) is a concept being developed
by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. The motive of WIN is to drive intelligent network (IN) capabilities, based on interim standard (IS)-41, into wireless networks WIN is defined as an architecture that separates the service logic and feature functionality from the wireless network switch and places that functionality in other platforms of the network. . Not only are subscribers insisting on more function ....etc

ABSTRACT
Wireless telecommunications can be divided into two broad categories: mobile communications and fixed wireless communications. The mobile communications market requires mobility or non-tethered communications. The goal of mobility is anytime, anywhere communications. Mobile communications technology must be able to allow roaming - the ability to provide service to a mobile phone users while outside their home system. On the other hand, fixed wireless is simply an alternative to ....etc

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
