An arrangement which is made up of two or more station with equal number of transmitter and receiver devices is a telecommunication system. You may be among the many individuals who are likely scratching their heads and struggling in vain to come up with a concrete definition for this term. Examples of telecommunications systems are the telephone network, the radio broadcasting. This systems also ensure that right message received by right user only and while transmitting is also check for transmission errors. The compressed signal, now occupying a narrower dynamic range, can be quantized with a uniform, or linear, spacing of thresholds and output levels. It is very complicated, time-consuming, and expensive. Telecommunication network has many types like wide area network, metropolitan area network, local area network, campus area network, personal area network, virtual private networks, client-server network, peer to peer network, network computing. Data and information can be easily shared and transferred over the computers or devices on the same network. Some of the key characteristics of LAN are: The Metropolitan Area Network is the larger version of LAN. Telecommunications are well-defined as communication over a medium that can be cable, telegraph, telephone, or radio broadcasting. 271 0 obj <> endobj xref 271 27 0000000016 00000 n The introduction of telecommunication in Ethiopia dates back to 1894. 0000001025 00000 n Some of the more notable and familiar examples of optical telecommunication systems include navigation lights, flares, semaphore communication and smoke signals.

Such signals, which continually vary among a range of values, are said to be analog, and in digital communications systems analog signals must be converted to digital form. But ordinary voice communications taking place by way of a telephone are not in binary form; neither is much of the information gathered for transmission from a space probe, nor are the television or radio signals gathered for transmission through a satellite link.

Optical telecommunication can be defined as the use of light to transmit information. A half-duplex system, such as a radio transmitter, can only send a message when the recipient has not engaged the transmission device. 4. The simplest possible signal of any kind that can be employed to transmit messages, the binary signal consists of only two possible values. Telecommunications can be unidirectional (when the sender is always the one sending the message) and bidirectional (the receiver at some point is the sender, i.e. Introduction to Telecommunication At the end of this session you would be able to: Describe the definitionof communication and communication process Detail the communication technology development Discuss six elements of computer and communication systems A telecommunications network is used for exchanging messages, a group of nodes is connected by links that help in exchanging messages between the nodes. The telecommunications sector consists of three basic sub-sectors: telecom equipment the largest , telecom services next . One of the oldest and most common forms of telecommunication systems used historically and in modern times is optical telecommunication. Setting up a WAN is not a simple task. Telecommunications engineering also overlaps . 0000005564 00000 n The encoded signal is made suitable for transmission by modulation onto a carrier wave and may be made part of a larger signal in a process known as multiplexing. It describes it as a remote transmission system and reception of signals of different nature by electromagnetic means. 0000004137 00000 n Some of the more notable and familiar examples of optical telecommunication systems include navigation lights, flares, semaphore communication and smoke signals. The output of the quantizer, on the other hand, must be restricted to a finite number of levels. The forms of telecommunication can be through audio, video or text, or a mixture of all three. Telecommunications technology refers to distance communications, such as radio, telephone, television, satellite, microwave, data communication, and computer networking. The network which is spread over a large geographic area is known as wide area network. An example of data being processed may be a unique identifier stored in a cookie. Links provide interconnections between nodes. The difference between the maximum rate of oscillation (or highest frequency) and the minimum rate of oscillation (or lowest frequency) of the sine waves making up the signal is known as the bandwidth (B) of the signal. The network can cover towns and cities of 50KMs or less. 0000002562 00000 n :+T3Pfr8-!~{eB3/_Xd77Y+R&]q'F*!(.

With that in mind, the point should be made that a device's status as either half-duplex or full-duplex does not necessarily reflect its level of sophistication or its capacity. All these systems are composed of a transmitter, one or more receivers and, finally, routers and switches. Fiber-optics and infrared sensors are also types of optical telecommunication. 2.
