INTRODUCTION ANALOG AND DIGITAL SIGNALS The signal is initially generated is in the form of an analog electrical voltage or current, produced for example by a microphone or some other type of transducer. The output from the readout system of a CD (compact disc) player, the data is already in digital form. An analog signal […]
Introduction Handheld wireless radios such as this Maritime VHF radio transceiver use electromagnetic waves to implement a form of wireless communications technology. Wireless operations permits services, such as long range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to […]

Get startedGPS Tracking (a) Tracking Global Positioning System (GPS) is a global satellite navigation system that used a network of satellites into orbit by the U. S. Department of Defense. GPS satellites circle the earth twice a day for a very precise orbit and transmit signal information to earth. GPS receivers for the information and use […]
What is vehicle tracking system? Vehicle tracking system is to track the vehicle’s location and it’s kind of electronic device and need to install in the vehicle. There are many kind of vehicle tracking system like GPS, RFID, fleet tracking system, VTU, satellite tracking, etc. Among them, I would like to introduce the GPS vehicle […]
Wireless sensor networks Mitigating performance degradation in congested wireless sensor networks CHAPTER 1: WIRELESS SENSOR NETWORKS 1.1 Introduction: Wireless sensor networks (WSNs)[1] have attracted tremendous attention in both academia and industry in recent years. A WSN consists of one or more sinks and perhaps tens or thousands of sensor nodes scattered in an area. The […]
Chapter 1:Introduction Library management system includes areas such as issuing and returning of books, classification of materials, and student’s console using various techniques. The two main features of this system include theft detection of unissued books and automatic system for issuing and returning of books for its members. The theft detection model that we have […]
1 Introduction The convenience and popularity of wireless technology has now extended into multimedia communications, where it poses a unique challenge for transmitting high rate voice, image, and data signals simultaneously, synchronously, and virtually error-free . That challenge is currently being met through Orthogonal Frequency Division Multiplexing (OFDM), an interface protocol that divides incoming data […]
1. Introduction The Dockland light Railway is one of Britain’s great high-tech Automatic Train Control (ATC) system, now carrying over 60 million passengers. This highly developed train control system has expended more rapidly than any UK railways. DLR officially launched in 1987 to serve the existing Docklands population and helps to regenerate the Isle of […]
Chapter 1.Introduction In recent years there has been an enormous growth in wireless communication devices and wireless users. The ever increasing demand for higher speed and reliability made researchers think about intelligent radios like Cognitive Radios (CR). But major amount of spectrum is available for licensed users. There are various communication bodies like the International […]
Developing data-centric sensor Introduction SENSOR networks are envisioned to be extremely useful for a broad spectrum of emerging civil and military applications such as remote surveillance, habitat monitoring, and collaborative target tracking. Sensor networks scale in size as time goes on, so does the amount of sensing data generated. The large volume of data coupled […]
Abstract In this proposal, I would like to investigate is the shopping system work for the visually impaired person. For the methodology part, my research is separate in two main parts. In the first part, I will interview with the supermarket customers to gain a basic understanding of the opinion to build a shopping system […]
Chapter 1 Fundamentals of Cellular Communication In this chapter, all the background knowledge which is required for this project has been discussed. 1.1 Cell The area covered by single BTS(base transceiver station) is known as cell. 1.1.1 Shape of cell The shape of cell depends upon the coverage of the base station. The actual coverage […]
Introduction I am one of the enthusiasts, energetic and active student studying IADCS (International Advanced Diploma in Computer Studies). In my second module in this course, I have to do the assignment for Enterprise Networking which demonstrates an understanding of the network, telephone system and two-way voice communications with patrolling police officers. In this assignment, […]
INTRODUCTION: With the rapid increase in number of mobile users, a massive number of calls originate from mobile subscribers, all over the world, everyday. With the increasing number of mobile users and originating calls, there is also an increase in emergency calls that originate from mobile stations. In many emergency cases the position is unknown […]
Introduction The primary goal of the project is to analyze of OFDM system and to assess the suitability of OFDM as a modulation technique for wireless communications. In the part of project is covered two leading successfully implementation of OFDM based technologies are Digital Video Broadcasting (DVB-T and DVB-H) and Long Term Evolution (LTE advanced […]
Radio Advertising Executive Summary Advertising in general expresses the positioning. Powerful advertising is the result of powerful planning. Great ideas and great ad campaigns don’t just pop out from no where, they are built on the key communication points that motivate sales. Radio is entirely a medium of sound, which evokes smells, sensations and visual […]
WIMAX TECHNOLOGY FOR TELE COMMUNICATION OVERVIEW: WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides fixed and fully mobile internet access. The current WiMAX revision provides up to 40 Mbit/s with the IEEE 802. 16m update expected offer up to 1 Gbit/s fixed speeds. The name “WiMAX” was created by the WiMAX Forum, […]
ABSTRACT: This is the world of VLSI . Presently all most all the people are using technology in various forms like mobiles, i-pods, i-phones etc. , Every one enjoys technology but only a few know about VLSI design in world design and its working. Coming to VLSI it is the process of creating integrated circuits […]
Thesis statement The citizen band radio and smartphones play almost similar activities in that they all have the role of facilitating communication. However, there is a difference between the smartphones and the central band radio. Despite there being a difference between the smartphones and these primary band radio, there still exists some similarities between them. […]
SiriusXM is a satellite radio corporation with approximately 32.7 million subscribers as of 2018. They broadcast music, news, and entertainment programming, mostly ad free, via satellites and corresponding terrestrial facilities. SiriusXM currently controls almost 30% of the US radio market, with its closest competitor, iHeartMedia Inc., trailing behind with only 17.5% of the market under […]
