Computers are often used as a tool in generation of information, though this information may not be always useful in itself. The information must be delivered to the right person at the right time from one location to another. This transfer of information is commonly called as data communication. Electronic communication basically comprises of telecommunication and data communications. The use of electronic media like telephone, telegraph, or television to transmit information, either directly or via computer is often referred as Telecommunication.
What is mobile communication? In simple terms, it is a wireless communication method used for transmission of data information via electromagnetic waves. A communication type that lets individuals to communicate and converse with one another whilst moving from one place to another, thus the name mobile. Some examples of mobile communication include cordless phones, pagers, cell phones, etc. A cell phone is a portable device that does not require a wired connection to establish communication.
1. INTRODUCTION 1.1 General introduction: A wireless network is a flexible data communications system, which uses wireless media such as radio frequency technology to transmit and receive data over the air, minimizing the need for wired connections (What is Wireless LAN, White Paper). Wireless networks are used to augment rather than replace wired networks and are most commonly used to provide last few stages of connectivity between a mobile user and a wired network. Wireless networks use electromagnetic waves to communicate information from one point to another without relying on any physical connection. Radio waves are often referred to as radio carriers because they simply perform the function of delivering energy to a remote
What are the two main issues in wireless communication? iv. What are microwaves? 1.1.2 Mobile and telecommunication History Mobile communication dates back to 1919 when United States began ship-to-shore wires mobile telephony on coastal steamers between Boston and Baltimore. In 1929, Amplitude Modulation (AM) technology
In this type of communication usually more time is taken as the receiver will be able to read the mind of the person only when he will reach to the thoughts through various other mediums with which he has sent the message. CHARACTERISTIC FEATURES OF COMMUNICATION “Communication in its simplest form is conveying of information from one person to another.” ––Hudson Communication is the thread, the intangible force which binds the large number of discrete individuals into a cohesive mass which behaves like a unique organization and communication flows through the arteries of this organism, keeps it alive and helps it perform various functions of ‘input’, ‘processing’, and ‘output’. Communication is considered to be complete only when the message is shared and understood with one another. Communication can also be defined as exchange of ideas, message, information or opinions between two or more persons through different modes. The common modes and methods by which information is transmitted are: (a) Written words (b) Oral
CHAPTER 1 INTRODUCTION 1.1 IMPORTANCE OF TRANSMISSION IN COMMUNICATION In telecommunications, transmission is the important process which is the backbone of communication systems which has recreated the world. Transmission of signals is a method of sending and propagating analog or digital information over a physical point- to- point receivers through a medium which is wired or wireless. The digital revolution has resulted in many digital telecommunication applications where the principles of data transmission are applied in their related field. The main sources of topics, their types and techniques used in transmission are discussed further. 1.2 ELEMENTS OF COMMUNICATION Input
Communication in social network has been well-known by people. Almost all people likes to communicate with others in social network. With the advanced of technology, social network is used as a way to communicate with others. It is due to its cost effective, high mobility and it can strengthen the relationship when someone is working or study far from the hometown. Hence, I believed that communication in social network is a good invention, but not the end of communication.
They facilitates through the connection and protecting of society. They link the whole community and protect the society by using their design and creation. With the increasing demand for faster and improved connectivity, telecommunication industry is poised to grow rapidly. Telecommunication industry provides services such as cellular phone, internet, high speed broadband and others. In the past, a cellular phone only served the purpose of making and receiving calls.
Marine VHF - This system was developed in December, 1991 to extend the wireless system to vessels navigating only in coastal waters, using only a part of the International VHF frequency. This development enabled ship-to-ship communication, the receipt of navigation alerts and weather information and communication with the Maritime Safety Agency in emergency and leisure-purpose coastal stations. IMPORTANCE OF RADIO COMMUNICATIONS IN COASTAL OPERATIONS 10. Why use a radio to communicate when on an operation in a coastal environment when we have our cellular phones, especially since messages can be intercepted easily? - We all know that the VHF radio is the primary method of communication used by other vessels at sea as well as the rescue services on land.
You would have probably been having a splendid day using free wi-fi service at a bus stop or stealing it from your neighbor but then eventually end up being irked at the sluggish speed as soon as multiple devices join the network. Presently we are using mobile data and wi-fi technology. Although these technologies have seen tremendous amount of advancement in the past few years or so, we are still far from the best. Instead of using copper cables or fiber-optic cable lines mobile internet uses a 2G/3G/4G network to connect to the internet. It provides greater portability and flexibility than the traditional phone-line systems.
