Cable Industry Regulation NETW 586 Telecom Law and Regulation Due Date: 25th August 2013. I. Abstract Cable industry has undergone a lot of evolution since the very first time it came into existence. First the paper will discuss cable television‚ telecommunication act 1934 and history of cable industry. The origin and importance of both regulation and deregulation of cable industry will be discussed. The various economic impacts; telecommunication‚ broadband

individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier frequency. Example: FDM can also be used to combine signals before final modulation onto a carrier wave. In this case the carrier signals are referred to as subcarriers: an example is stereo FM transmission‚ where a 38 kHz subcarrier is used to separate the left-right difference signal

CHAPTER 1 Introduction Chapter 1 Introduction 1.1 What is WLAN? 1.1.1 WLAN Wireless Local Area Network (WLAN) is a kind of local area network which established using a wireless link between the service providers and the clients using some wireless equipment. This network development is based on the IEEE 802.11 standard. 1.1.2 IEEE 802.11 IEEE 802.11 denotes a set of Wireless LAN/WLAN standards developed by working group 11 of the IEEE LAN/MAN Standards Committee (IEEE 802).

radio transmissions for broadcasting and two way radio communication applications. Although one of the earliest used forms of modulation it is still in widespread use today. The first amplitude modulated signal was transmitted in 1901 by a Canadian engineer named Reginald Fessenden. He took a continuous spark transmission and placed a carbon microphone in the antenna lead. The sound waves impacting on the microphone varied its resistance and in turn this varied the intensity of the transmission. Although

TELECOMMUNICATION A Gower telephone‚ at the Musée des Arts et Métiers in Paris Telecommunication is the transmission of messages‚ over significant distances‚ for the purpose of communication. In earlier times‚ telecommunications involved the use of visual signals‚ such as smoke‚ semaphore telegraphs‚ signal flags‚ and optical heliographs‚ or audio messages via coded drumbeats‚ lung-blown horns‚ or sent by loud whistles‚ for example. In the modern age of electricity and electronics‚ telecommunications

Real world Applications of Electronics This chapter introduces some of the real world applications of Electronics; 1. Audio Systems 2. Radio Transmission & Reception 3. Control Systems 1. AUDIO SYSTEMS: Any system operating at audio frequencies (20 to 20‚000 Hz) is called an Audio System‚ e.g. an intercom‚ music systems etc. Following diagram (fig.1.1) shows the main features of such an audio system; FIGURE 1.1: Main blocks of an audio system 1.1 Radio tuner: It receives radio signals and converts

FM: It stands for frequency modulation. The radio wave has a variable frequency and the technique makes radio reception fairly free from static interference has become the most favored transmission method as a result.

the antenna and achieve impedance matching between load impedance and transmission line’s impedance. Among a wide range of different antennas‚ our group decide to build up a Yagi Uda antenna to fulfill this assignment for two main reasons. Firstly‚ the gain that Yagi Uda antenna provides is very high. Hence for transmission‚ Yagi Uda antenna makes sure all the transmitted wave to be directed to required area and for reception‚ it can receive maximum signal from the required area. Secondly‚ Yagi

NT1310 : Week 1 Telecommunications By: Marvin Redd You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system‚ your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor

relates to McQuail’s communication theory. Comparing the influence of mass media to the early century‚ McQuail D. (2002) associates the first concept of communication to the ‘teachings’ and guidance towards the masses through propaganda. This transmission perception is communication at its simplest level. In this model‚ the major concern is to dispatch the message regardless of the receiver having reached an understanding with the source and hence omitting feedback. For example‚ it is evident in
