Structural calculations are required when boring under heavy traffic areas such as highways or when attaching to other structures such as bridges. Shoring also has to be taken into consideration for larger trenches or pits. Conduit structures often include encasements of slurry that needs to be designed to support the structure and withstand the environment around it soil type, high traffic areas, etc. As electrical engineers , OSP engineers are responsible for the resistance, capacitance, and inductance RCL design of all new plant to ensure service is clear and crisp and data service is clean as well as reliable. In addition power requirements have to be calculated and provided to power any electronic equipment being placed in the field. potential has to be taken into consideration when placing equipment, facilities, and plant in the field to account for lightning strikes, high voltage intercept from improperly grounded or broken power company facilities, and from various sources of electromagnetic interference. As civil engineers , OSP engineers are responsible for drafting plans, either by hand or using Computer-aided design CAD software, for how telecom plant facilities will be placed. Often when working with municipalities trenching or boring permits are required and drawings must be made for these. As civil engineers, telecom engineers provide the modern backbone for all technological communications distributed throughout civilizations today. Unique to telecom is the use of air-core cable which requires an extensive network of air handling equipment such as compressors, manifolds, regulators and hundreds of miles of air pipe per system that connects to pressurized splice cases all designed to pressurize this special form of copper cable to keep moisture out and provide a clean signal to the customer. As political and social ambassador , the OSP engineer is a telephone operating company's face and voice to the local authorities and other utilities. OSP engineers often meet with municipalities, construction companies and other utility companies to address their concerns and educate them about how the telephone utility works and operates.

The development of modern telecommunications from the first electrical telegraph over the last years is the result of the work of thousands of scientists, engineers and even researchers from quite different walks of life. Few of them were solely responsible for the invention for which they are famous, most major inventions being the culmination of the work of many individuals. Born : Minehead, England, 16 December Clarke proposed in an article published in Wireless World in , the use of geostationary satellites for world-wide radio coverage. These have since become a very significant part of the world's communication systems. Clarke's other inventions include the use of satellite platforms for earth observation, and the manoeuvrable solar sail for low-acceleration interplanetary flight. Transistors can detect, amplify and rectify currents and switch them on and off. They are small, cheap and use very little energy. These properties have made it possible to develop electronic switching of communications. Without them. Transistors have made possible modern computers, pocket calculators, hearing aids, portable and casette players, high-fi systems and a host of their equipment. Samuel Finlay Breese Morse was the inventor of the electromagnetic recording telegraph and the developer of the code of dots and dashes known as the . In his early years Morse's interests lay principally in the arts. It was not until , at the age of 41, that he completed the drafts of his electrical telegraph which was first publicly demonstrated in August Morse applied for, and received, a United States Patent, but his petition to Congress for a credit to defray the costs of setting up an experimental public telegraph was not accepted until It was finally on 24 May that Morse transmitted his first message from Washington D. Although has now largely been replaced by more modern telecommunication services, Morse's original concept is still in use and the Morse Code still remains a universal standard for sending messages.

Written in clear and direct language for AQF Level 2, it supports student learning through numerous examples and diagrams. Such a plan as this, although impracticable at the present moment, will, I firmly believe, be the outcome of the introduction of the telephone to the public. Not only so, but I believe, in the future, wires will unite the head office of the in different cities, and a man in one part of the country may communicate by word of mouth with another in a different place. Throughout his life he also laboured to help the deaf. Born : Bologna, Italy, 25 April As a student, was particularly interested in magnetism and the application of Hertzian waves. On 2 June he applied for his first patent concerning radio. A highly practical and enterprising man, Marconi was quick to commercialize his discoveries and, in July he founded in London the first company for . In he managed to transmit by radio a message across the English Channel and, in , he sent signals across the Atlantic Ocean from Cornwall, England to Signal Hill, Newfoundland. By a transatlantic wireless service had been established and in he was awarded the Nobel Prize for physics. In he discovered transmission which enabled him to offer a world-wide communication service. Throughout his life, Marconi dedicated himself to the expansion of wireless telegraphy and a total of nearly patents were awarded either to him or the companies he directed. Died : St. After Hertz had demonstrated the existence of electromagnetic waves Popov experimented with ways of detecting them by a receiver. His experiments were demonstrated on 7 May to the Russian Physics and Chemistry Society and reported a few days later in the Kronstadtskii Vestnik. The report concluded that the aim "is to show that it is theoretically possible to transmit signals over a certain distance without the use of conductors, in other words, after the fashion of visual telegraphy but with the aid of electrical radiations". Born : near Rochester, NY, Almon B. Strowger invented an automatic telephone exchange in A funeral undertaker, Strowger suspected that, by design or by error, local telephone operators deviated his business calls to rival firms. He therefore had the idea of switching telephone calls automatically and his work on this idea led to the installation of the first commercial automatic exchange in the world at La Porte Indiana in the United States. From , Academician Sergei Pavlovich Korolev directed the design of rockets in the USSR which led to the launch of Sputnik-1, the first artificial earth satellite, on 4 October He was responsible for directing the development of many more recent rockets. Rocket technology is essential for the launching of artificial earth satellites which play a very important part in modern telecommunications. Korolev also directed the development of a number of satellites including the Molniya-1 series of telecommunications satellites. Find out more about work placements available.

The receiving telephone converts the signals into audible sound in thereceiver, or sometimes a loudspeaker. are a duplex communications medium, meaning theyallow the people on both ends to talk simultaneously. The , consisting of a worldwide netof telephone lines, fiberoptic cables, transmission, cellular networks, communications satellites,and undersea telephone cables connected by switching centers, allows any telephone in the world tocommunicate with any other. Each telephone line has an identifying number called its . Toinitiate a the user enters the other telephones number into a numeric keypad on the phone. Graphic symbols used to designate telephone service or phone-related information in print, signage, andother media include. Although originally designed for simple voice communications, most modern telephones have manyadditional capabilities. They may be able to record spoken messages, send and receive text messages, takeand display photographs or video, play music, and surf the Internet. A current trend is phones that integrateall mobile communication and computing needs; these are called . : The telex network is a switched network of similar to a telephone network, for thepurposes of sending text-based messages. This network provided the first common medium for internationalrecord communications using standard signaling techniques and operating criteria as specified bythe International Telecommunication Union ITU. Telex messages are routed by addressing them to a telex address, e. Solutionsalso exist for the automatic routing of messages to different telex terminals within a subscriber organization,by using different terminal identities, e. A major advantage of telex is that the receipt of the message by the recipient could be confirmed with ahigh degree of certainty by the "answerback". At the beginning of the message, the would transmit aWRU Who aRe yoU code, and The WRU code would also be sent at the end of the message, so a correctresponse would confirm that the connection had remained unbroken during the message transmission. Thisgave telex a major advantage over less verifiable forms of communications such as telephone and . FASCIMILE: Fax short for facsimile , sometimes called telecopying or telefax, is the telephonictransmission of scanned printed material both text and images , normally to a telephone number connectedto a printer or other output device. The original document is scanned with a fax machine or a telecopier ,which processes the contents text or images as a single fixed graphic image, converting it into a bitmap,and then transmitting it through the telephone system. The receiving fax machine reconverts the codedimage, printing a paper copy. For many decades before digital technology became widespread the scanneddata was transmitted as analog. Although businesses usually maintain some kind of fax capability, the technology has faced increasingcompetition from Internet-based alternatives. Fax machines still retain some advantages, particularly in thetransmission of sensitive material which, if sent over the Internet unencrypted, may be vulnerable tointerception, without the need for telephone tapping. In some countries, because electronic signatures on 5. Unit 1, prepared by: Er Lochan Raj NeupaneManmohan Memorial Polytechnic Page 5contracts are not recognized by law while faxed contracts with copies of signatures are, fax machines enjoycontinuing support in business. Personal computers have also long been able to handle incoming andoutgoing using analogue or ISDN, eliminating the need for a stand-alone fax machine. Thesesolutions are often ideally suited for users who only very occasionally need to use fax services. A videophone is a telephone with a video display, capable of simultaneous video and audio forcommunication between people in real-time. Videophone service provided the first form of video ,later to be followed by videoconferencing, , and finally high-definition tele presence. At the beginning of its commercial deployment from the s through the s, video telephony alsoincluded image phones which would exchange still images between units every few seconds overconventional type telephone lines, essentially the same as slow scan TV systems. The development ofadvanced technology video codecs and high bandwidth Internet telecommunication services allowedvideophones to provide high quality color service between users almost any place in the world that theInternet is available, often at low or nominal costs. In the present day videophones have become widely available at reasonable cost, although not widelyused in everyday communications for a variety of reasons. However, they are particularly useful tothe deaf and speech-impaired who can use them with sign language, and are becoming increasingly popularfor educational instruction, telemedicine and to those with mobility issues. A is a wireless telecommunications device that receives and displays numeric or text messages, orreceives and announces voice messages. One-way can only receive messages, while responsepagers and two-way pagers can also acknowledge, reply to, and originate messages using an internaltransmitter. Pagers operate as part of a paging system which includes one or more fixed or inthe case of response pagers and two-way pagers, one or more base stations , as well as a number of pagerscarried by mobile users. These systems can range from a restaurant system with a single low-powertransmitter, to a nationwide system with thousands of high-power base stations. One of the first practical paging services was launched in for physicians in the New York City area. In , John Francis Mitchell combinedelements of Motorolas Walkie Talkie and automobile radio technologies to create the first transistorizedpager, and from this point, paging technology continued to advance, and pager adoption continued toexpand, until the early s. However, by the mids, as cellular technologies became cheaper and morewidely available, advanced services began to displace paging as a commercial product. Today, pagers existlargely as niche products, finding preferential use in applications such as hospitals, publicsafety, and retail locations where their simplicity, high reliability, and low cost represent significantadvantages. A also known as a cellular phone, cell phone, and a hand phone is a device that can makeand receive telephone calls over radio link while moving around a wide geographic area. It does so byconnecting to a provided by a , allowing access to the publictelephone network. By contrast, a is used only within the short range of a single, privatebase station. Unit 1, prepared by: Er Lochan Raj NeupaneManmohan Memorial Polytechnic Page 6In addition to telephony, modern mobile phones also support a wide variety of other services such as textmessaging, MMS, email, , short-range wireless communications infrared, ,business applications, gaming and photography. Mobile phones that offer these and more general computingcapabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by John F. Mitchell and Dr. MartinCooper of Motorola in , using a handset weighing around 2. In , the DynaTACx was the first to be commercially available. From to , worldwide mobile phone subscriptionsgrew from They provide similar functionality to terrestrial mobiletelephones; voice, short messaging service and low-bandwidth internet access are supported through mostsystems. Depending on the architecture of a particular system, coverage may include the entire Earth, oronly specific regions. The mobile equipment, also known as a terminal, varies widely. Early satellite phone handsets had a sizeand weight comparable to that of a lates or earlys mobile phone, but usually with a largeretractable . More recent satellite phones are similar in size to a regular mobile phone whilesome prototype satellite phones have no distinguishable difference from an ordinary . Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable. Radiospectrum refers to the part of the electromagnetic spectrum corresponding to radio frequencies — that is,frequencies lower than around GHz or, equivalently, wavelengths longer than about 1 mm. Unit 1, prepared by: Er Lochan Raj NeupaneManmohan Memorial Polytechnic Page 7Different parts of the are used for different radio transmission technologies andapplications. Radio spectrum is typically government regulated in developed countries and, in some cases, issold or licensed to operators of private radio transmission systems for example, cellular telephone operatorsor broadcast television stations. Ranges of allocated frequencies are often referred to by their provisioneduse for example, cellular spectrum or television spectrum 1. Achannel is used to convey an information signal, for example a digital bit stream, from one orseveral or transmitters to one or several receivers. A channel has a certain capacity for transmittinginformation, often measured by its bandwidth in Hz or its data rate in bits per second. Communicating data from one location to another requires some form of pathway or medium. Thesepathways, called communication channels, use two types of media: cable twisted-pair wire, cable, and fiber-optic cable and broadcast microwave, satellite, radio, and infrared. Cable or wire line media uses physicalwires of cables to transmit data and information. Twisted-pair wire and coaxial cables are made of copper,and fiber-optic cable is made of glass. may be divided asi Wired channel: it always has some pair of cable for ex. Co-axial cable, optical fibre, twistedpair cable etc. Unit 1, prepared by: Er Lochan Raj NeupaneManmohan Memorial Polytechnic Page 8ii Wireless channel: in wireless communication message signal is transmitted through openspace by electromagnetic wave also called . These waves are radiated fromtransmitter in open space through a device called antenna. However, some noise is also produced inthe receiver. Classification of Noise Noise may be put into following two categories. Internal noise1 External noises, i. External noise cannot be reduced except bychanging the location of the receiver or the entire system. Internal noise on the other hand can be easilyevaluated mathematically and can be reduced to a great extent by proper design. As already said, because ofthe fact that internal noise can be reduced to a great extent, study of noise characteristics is a very importantpart of the communication engineering. External noise may be classified into the following three types:i Atmospheric noisesAtmospheric noise or static is caused by lighting discharges in thunderstorms and other natural electricaldisturbances occurring in the atmosphere. These electrical impulses are random in nature. Hence the energy isspread over the complete frequency spectrum used for radio communication. Atmospheric noise accordingly consists of spurious radio signals with components spread over a widefrequency range. These spurious radio waves constituting the noise get propagated over the earth in the samefashion as the desired radio waves of the same frequency. Accordingly at a given receiving point, the receivingantenna picks up not only the signal but also the static from all the thunderstorms, local or remote. The fieldstrength of atmospheric noise varies approximately inversely with the frequency. Thus large atmospheric noiseis generated in low and medium frequency broadcast bands while very little noise is generated in the VHF andUHF bands. For these two-reasons, the atmospheric noise becomes less severe at Frequencies exceeding about30MHz. However,these may be put into following two subgroups. Solar NoiseThis is the electrical noise emanating from the sun. Under quite conditions, there is a steady radiation ofnoise from the sun. The intensity produced by the sun varies with time. In fact, the sunhas a repeating Year noise cycle. During the peak of the cycle, the sun produces some amount of noise that 9. Unit 1, prepared by: Er Lochan Raj NeupaneManmohan Memorial Polytechnic Page 9causes tremendous radio signal interference, making many frequencies unusable for communications. Duringother years. The noise is at a minimum level. Cosmic noiseDistant stars are also suns and have high temperatures. Use OCW to guide your own life-long learning, or to teach others.

This was demonstrated successfully over three miles five kilometres on 6 January and eventually over forty miles sixty-four kilometres between Washington, D. The patented invention proved lucrative and by telegraph lines in the United States spanned over 20, miles 32, kilometres. The first successful transatlantic telegraph cable was completed on 27 July , allowing transatlantic telecommunication for the first time. Earlier transatlantic cables installed in and only operated for a few days or weeks before they failed. The first commercial telephone services were set up in and on both sides of the Atlantic in the cities of New Haven and London. held the master patent for the telephone that was needed for such services in both countries. The technology grew quickly from this point, with inter-city lines being built and telephone exchanges in every major city of the United States by the mids. However no cable connection existed until TAT-1 was inaugurated on September 25, providing 36 telephone circuits. In , Bell and co-inventor Charles Sumner Tainter conducted the world's first wireless telephone call via modulated lightbeams projected by . The scientific principles of their invention would not be utilized for several decades, when they were first deployed in military and fiber-optic communications. Over several years starting in the Italian inventor Guglielmo Marconi built the first complete, commercially successful wireless telegraphy system based on airborne electromagnetic waves radio transmission. On March 25, , Scottish inventor publicly demonstrated the transmission of moving silhouette pictures at the London department store Selfridges. In October , Baird was successful in obtaining moving pictures with halftone shades, which were by most accounts the first true television pictures. Baird's first devices relied upon the Nipkow disk and thus became known as the . It formed the basis of semi-experimental broadcasts done by the British Corporation beginning September 30, The first U. It was used to send a Christmas greeting to the world from U. President Dwight D. Courier 1B , built by Philco , also launched in , was the world's first active repeater satellite. Satellites these days are used for many applications such as uses in GPS, television, internet and telephone uses. Telstar was the first active, direct commercial communications satellite. Relay 1 was launched on December 13, , and became the first satellite to broadcast across the Pacific on November 22, The first and historically most important application for communication satellites was in intercontinental long distance telephony. The fixed Public Switched Telephone Network relays telephone calls from land line telephones to an earth station , where they are then transmitted a receiving via a geostationary satellite in Earth orbit. Improvements in submarine communications cables , through the use of fiber- optics , caused some decline in the use of satellites for fixed telephony in the late 20th century, but they still exclusively service remote islands such as Ascension Island , Saint Helena , Diego Garcia , and Easter Island , where no submarine cables are in service. There are also some continents and some regions of countries where telecommunications are rare to nonexistent, for example Antarctica , plus large regions of Australia , South America , Africa , Northern Canada , China , Russia and Greenland. After commercial long distance telephone service was established via communication satellites, a host of other commercial telecommunications were also adapted to similar satellites starting in , including mobile satellite phones , satellite radio , satellite television and satellite Internet access. The earliest adaption for most such services occurred in the s as the pricing for commercial satellite transponder channels continued to drop significantly. However, it was not until the s that researchers started to investigate — a technology that allows chunks of data to be sent between different computers without first passing through a centralized mainframe. A four- network emerged on 5 December This process is important because ARPANET would eventually merge with other networks to form the Internet, and many of the communication protocols that the Internet relies upon today were specified through the Request for Comment process. Optical fiber can be used as a medium for telecommunication and computer networking because it is flexible and can be bundled into cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters. In Charles K. After a period of research starting from , the first commercial fiber- optic was developed, which operated at a wavelength around 0. The first fibre optic cable system in the world seems to have been installed by Rediffusion in Hastings, East Sussex, UK in The cables were placed in ducting throughout the town, and had over subscribers. They were used at that time for the transmission of television channels, not available because of local reception problems. The first transatlantic telephone cable to use optical fiber was TAT-8 , based on Desurvire optimized laser amplification technology. It went into operation in In the late s through , industry promoters, and research companies such as KMI, and RHK predicted massive increases in demand for communications bandwidth due to increased use of the Internet , and commercialization of various bandwidth-intensive consumer services, such as video on demand. Internet protocol data traffic was increasing exponentially, at a faster rate than integrated circuit complexity had increased under Moore's Law. Transmitter information source that takes information and converts it to a signal for transmission. In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna , produces radio waves. In addition to their use in broadcasting , transmitters are necessary component parts of many electronic devices that communicate by radio , such as cell phones ,. Transmission medium over which the signal is transmitted. For example, the transmission medium for sounds is usually air, but solids and liquids may also act as transmission media for sound. Many transmission media are used as communications channel. One of the most common physical medias used in networking is copper wire. Strowger invented an automatic telephone exchange in A funeral undertaker, Strowger suspected that, by design or by error, local telephone operators deviated his business calls to rival firms. He therefore had the idea of switching telephone calls automatically and his work on this idea led to the installation of the first commercial automatic exchange in the world at La Porte Indiana in the United States.

Born : Hamburg, Germany, 22 February Heinrich Hertz discovered electromagnetic waves in at the University of Karlsruhe, confirming the theory of James Clark Maxwell who had predicted their existence. Hertz's discovery is the basis for radio technology and for the later development of broadcasting and television. Born : Como, Italy, 18 February Alessando Volta studied the generation of by chemical action. He invented the first electrical cell, the precursor of the electrical battery which was for many years the principle power supply for telecommunications. In he visited Saussure in Geneva and Voltaire at Ferney. Born : Smiljan, Croatia, 10 July worked on alternating currents and high frequency radio waves. He demonstrated the transmission of electrical energy without wires and, in , constructed an emitting station in the state of Colorado, United States from which he was able to receive 1, km away clear radio signals. He invented a system of inductive coupling between two circuits. He was granted over patents on subjects such as the construction of electrostatic capacitors, the insulation of electrical conductors, a frequency meter, etc. Born : Magneux, France, 11 September Emile Baudot dedicated his life to the development of a fast-printing telegraph. After successively improved versions, he demonstrated at the International Exhibition of Electronics a perfected model which could transmit six simultaneous messages. The Baudot system was used throughout the world for terrestrial and undersea links for over 70 years. Contact us Privacy notice Accessibility Report misconduct.
