  3. 3. Teach Yourself Telecommunications Series WHY THIS PROGRAM? <ul><li>THE CYBERSCHUUL has been involved in capacity building for the telecommunications industry since 2001. Its forerunners started offering training in telecommunications since 1996. The Institute also has been involved in consultancies in human resource development and instituted Job Search opportunities for several job seeking Nigerians since its establishment. </li></ul><ul><li>Advertisers say response to job adverts show that there were large but poor responses to vacancy announcements. What is more, Nigerian Job seekers can do with some support in how to develop their skills and how to present such skills where they have them. </li></ul><ul><li>The irony of the Nigerian situation is that while there are plenty of Jobs, there are also plenty of unemployable job seekers. </li></ul><ul><li>Skills deficiency is one issue, presentation of one’s skill is another. </li></ul><ul><li>For example 17,000 engineers may be required for 100 million phones which is projected for the year 2015 </li></ul><ul><li>30,000 other skilled workers may be required for the industry </li></ul><ul><li>Skills will be what matter, not number. </li></ul><ul><li>These notes are a response attempt to correcting the impasse. </li></ul>
  4. 4. FOCUS OF THE TEACH YOURSELF PROGRAMS <ul><li>This support program is essentially for telecommunications industry especially in the Nigerian environment </li></ul><ul><li>They are good for all those who wish to make a career in telecommunications </li></ul><ul><li>The truth really is that almost everybody has a place in telecommunications and a role to play </li></ul><ul><li>Telecommunication provides abundant opportunities for investment and jobs </li></ul>
  5. 5. Introduction This material is designed to assist the person who desires to appraise himself/herself with current and relevant issues of industry, technology and general knowledge in his/her bid to seek employment in the telecommunications sector especially in Nigeria. It is compiled by specialists who have worked in the sector, taught telecommunication to professionals, consulted for telecommunication companies and handled employment matters at corporate levels of several startup and established companies. In a way, it is meant to address observed deficiencies of local experts, fresh graduates and other professionals who intend to build a career in or to crossover to the telecommunications profession.
  6. 6. How to use the material. <ul><li>Although it can serve as a good reading material for general knowledge, those who want to use it to prepare themselves for job interview are advised not to read the material as a story book. Rather, they should attempt answering the questions which the question slides provide and go ahead to evaluate how close they had been to the answers offered in the Answer slides which usually immediately follow. </li></ul><ul><li>Like anything in technology, there are no complete answers to any question and the answers offered here may just be one or some of the possible answers to a question. A person should score 80% correct answers to make him/her feel ready and capable of facing any interview panel to seek positions in telecommunication firms. </li></ul>
  7. 7. What makes the difference between 250 slides and 300 slides? <ul><li>The difference is that 50 additional slides were added to the 250 slides to cover new subjects such as Convergence, Number Portability, 3G systems, Wimax, Co-location of telecommunications infrastructure and a few new developments in the industry in Nigeria and worldwide in the second half of 2008. </li></ul><ul><li>The material actually started in 2003 with 100 slides, went higher to 150 in 2005, to 250 in 2007 and 300 in 2009. </li></ul>
  8. 8. PACKAGE YOURSELF FOR JOB SEARCH <ul><li>Preparing for a new job starts from applying for the job </li></ul><ul><li>The quality of your applications matters. Do not joke with it. </li></ul><ul><li>The following notes will guide you on how to write your applications, prepare for interviews, and keep a good job. </li></ul>
  9. 9. DEVELOPING A PROFESSIONAL <ul><li>CV[Curriculum Vitae] or </li></ul><ul><li>PROFILE, or </li></ul><ul><li>Resume. </li></ul><ul><li>They all chronicle your achievements, personal information, and career history. </li></ul>
  10. 10. What you should do when applying for a job <ul><li>Write an application to specifically ask for each position. Not one for all positions. </li></ul><ul><li>Avoid sending a stereotype CV as response to adverts. Rather, respond to an advert by writing an application to show that you are qualified for the position and that you are the guy the position is waiting for. </li></ul><ul><li>Write your application as a mail, not as an attachment to a mail if you are applying via the Internet. </li></ul><ul><li>Avoid attaching your CV as email attachment with the note ‘attached herewith’ ‘my CV attached’, ‘the attached for consideration’, ‘see the attached’. Point is: such applications do not deserve to be read let alone considered. </li></ul><ul><li>Be brief but offer essential details starting with the current relevant positions you held in recent times. </li></ul><ul><li>Avoid gaps that cannot be explained or explain it right away. </li></ul><ul><li>Start from now and work backwards in cataloguing your attainments. </li></ul><ul><li>Recent achievements carry more value than ancient ones in most cases </li></ul><ul><li>Separate academic courses from professional training. </li></ul><ul><li>Describe things rather than just list them </li></ul><ul><li>Say what your company does, even if it is sounds too obvious. </li></ul><ul><li>The number of people you are responsible for matters, that’s what makes you a manager. </li></ul><ul><li>Read what you have written over and over again and correct it along. </li></ul><ul><li>Write a CV for a particular vacancy, do not just drop standard CV at everybody </li></ul><ul><li>Do not employ your relative to send your application by email on your behalf </li></ul><ul><li>Use simple and popular email software [e.g. Outlook Express] rather than the ‘way-out’ one which your target reviewer may not have. </li></ul>
  11. 11. What You should not do <ul><li>In your application letter , or CV, or Profile </li></ul><ul><li>Please do not lie </li></ul><ul><li>Do not overuse presentation effects </li></ul><ul><li>Do not include details that do not add value </li></ul><ul><li>Do not pay undue attention to unimportant information[ like religion, tribe, sex, ] </li></ul><ul><li>Write like a serious person, not like a braggart </li></ul><ul><li>Write good English, corrected by another person if you can find one. </li></ul><ul><li>Be polite and respectful even in your writing </li></ul>
  12. 12. USING THE INTERNET TO PLACE YOUR RESUME <ul><li>Some guys put their resume on a webpage on the Internet. Good idea and a great way to increase exposure. But it's also a dangerous way for your resume to end up on your boss's desk! (Should there be layoff plan round the corner, you’ve had it!) When posting your resume on the internet, you'll likely have to hide your name except where you are self-employed and have nothing to loose if any one sees it. </li></ul>
  13. 13. HOW TO PREPARE FOR YOUR INTERVIEW <ul><li>Make it appoint of duty to find out everything you can about the specific position you are about to be interviewed for. At least you must find out things about the company, its products, and a few other public domain information. You may use the web for example to find all the information. You may also ask those who work there. </li></ul><ul><li>The better you understand the position and the employer's needs the more effectively you can show how you'll benefit their organization. Read the job ad thoroughly - it will often tell you some of the employers major concerns. </li></ul>
  14. 14. AT THE INTERVIEW <ul><li>Most interviewers will take their questions from your answers </li></ul><ul><li>Read wide as a habit, a job interview is not an examination for which you have to read the night before </li></ul><ul><li>If you do not know , say so rather than making bad guesses </li></ul><ul><li>Discuss your present job, not your present employer </li></ul><ul><li>Avoid sounding cheap just because you are jobless </li></ul><ul><li>Avoid blaming your country for your woes </li></ul><ul><li>Convince the interviewers that you are skilled. If you are not then you already know your problem. Solve it. Go to THE CYBERSCHUUL for Training. </li></ul>
  15. 15. TYPES OF INTERVIEW QUESTIONS <ul><li>Practice responses to interview questions - but don't try to memorize them. Being yourself is essential to interview success. Responses need to feel and sound natural. </li></ul><ul><li>When you've thought through how you can add value to a specific employer, you'll be able to easily add examples of how in the answers you provide. </li></ul>
  16. 16. KNOWLEDGE, ABILITY AND SKILLS QUESTIONS <ul><li>These questions often deal with the technical aspects of the job or basic knowledge that is essential to learn the job. In engineering jobs experience is your best asset. Sometimes you may be lucky the interviewers themselves read texts to prepare for the interview and you are the type that reads wide, you would have stumbled on some of their questions. </li></ul>
  17. 17. SITUATIONAL QUESTIONS AND BEHAVIOUR BASED QUESTIONS <ul><li>Situation questions provide you with a hypothetical situation and ask how you would deal with it. Employers can check your understanding of specific processes as well as your interpersonal or working with others skills. </li></ul>
  18. 18. AFTER GETTING A JOB <ul><li>Serve your employer faithfully at all times. Your are developing yourself and on top of it being paid to live. </li></ul><ul><li>If you should quit your job, discuss it in the most civilised manner with your boss[es]. They cannot hold you down if you really want to leave. But avoid playing games simply because you want to move on. </li></ul><ul><li>No company can pay more than between 8% and 12% of all its payout as emolument to its workers. Know therefore that a lot of money needs to come in before workers can get part of it. If you go to solve a software problem and by your effort a cheque for 10 million naira is paid to your employer, do not feel you are being cheated if you are not given a fraction of it as bonus. </li></ul><ul><li>You can help to kill the business. Want to know how? See next page </li></ul>
  19. 19. WANT TO HELP KILL THE BUSINESS? <ul><li>If you want to kill your employer’s business </li></ul><ul><li>Try the following fine suggestions </li></ul><ul><li>If you should engage in discussion during work hours, make sure it is the 2007 election issue and who should have replaced Obasanjo at Aso Rock. Or better still the Sharia matter which has refused to die anyway. </li></ul><ul><li>If you have a computer, use it mainly for sending and receiving mails which are remotely connected to work. The computer is your best bet if you should look busy to anybody. Spams will help you to elongate your time on the web. </li></ul><ul><li>Put lots of books on your table and also on the floors around you. If you don’t find enough, go out to buy computer manuals. They are usually fat. Don’t worry about their hollow content. They are beautifully written after all and you wont read them anyway. </li></ul><ul><li>Always hold a document in your hand when moving round the office. It shows people that you are heading for a meeting. Not newspaper please because they may think you are heading for the toilet. </li></ul><ul><li>Want more? See next slide: </li></ul>
  20. 20. MORE WAYS TO HELP KILL THE BUSINESS <ul><li>At close of business each day ask for someone to help you pack documents into your car. They will respect you for taking work home and may even be advising you not to kill yourself with work. Ignore them, after all you know what you are doing. </li></ul><ul><li>Switch your phone permanently on voice mail. Most callers will want you to do something for them. They are irritants. What’s more, when they get switched to voice mail at all times, they will assume you are at important meetings all day. </li></ul><ul><li>When everybody closes for the day, stay behind. If you have nothing to do watch movie on the net or visit Genevieve’s website which gets updated everyday after all. Lagbaja too has a good website these days </li></ul><ul><li>Try to sigh loudly at least once every hour. It gives the impression of overwork or that you are under pressure. Whichever way, they’ll respect you. </li></ul>
  21. 21. AND MORE…on killing the business <ul><li>Computer magazines are wonderful documents. Read them most times and memorize the lots of jargons they contain. Once you use those jargons in discussion, everybody will think you acquired American education. </li></ul><ul><li>When juniors come around you, look angry. They will believe you are overworked and understandably moody. It helps keep your personality high up. </li></ul><ul><li>If at years end you are assessed and not fired, arrange a thanks-giving and invite everybody in the office to the show. </li></ul><ul><li>If they score you low and fire you, never disclose to anybody where you learnt the tricks you used in getting at the destination. At least do not mention The Teach yourself Telecommunications Series of training programs </li></ul>

  63. 63. What are Deregulated Telecommunications Services <ul><li>These services include: </li></ul><ul><li>Sales and Installation of Terminal equipment (Mobile Cellular Phones, Satellite Communication and Switching equipments etc).  </li></ul><ul><li>Public Payphone Services.  </li></ul><ul><li>Internet Services.  </li></ul><ul><li>Prepaid Calling Card Services.  </li></ul><ul><li>PNL LEO (Local Exchange Operator)  </li></ul><ul><li>Paging Services. </li></ul><ul><li>Trunk and 2-Way Radio Network Services.  </li></ul><ul><li>Fixed Telephony Services, employing cable and Radio. </li></ul><ul><li>Satellite Network Services (e.g. Domestic VSAT networks). </li></ul><ul><li>Repairs & Maintenance of telecommunications facilities.  </li></ul><ul><li>Cabling services.  </li></ul><ul><li>Tele-Centers/Cyber Cafes. </li></ul><ul><li>Non-commercial/User Operated Radio Networks </li></ul>
  64. 64. Number Portability <ul><li>Number Portability, NP means the flexibility with which subscribers can change their service provider, geographical position or service type without changing their telephone number. </li></ul><ul><li>Number portability offers benefits to subscribers because they can more easily change their service providers without having to notify friends and contacts about a telephone number change. And that is important for business. It increases the level of open competition, thereby enhancing quality of service and customer care. </li></ul><ul><li>Service providers are not likely to like Number portability but it will make them open more interest in roaming agreements. It has the potential of being good for those service providers who have better customer service policies, network coverage, service quality and pricing. </li></ul>
  65. 65. NUMBER PORTABILITY In Nigeria <ul><li>  Number portability is the ability of telephone subscribers to retain their existing phone number(s) when changing their telephone network (Operator). This allows consumers to choose between competing Networks based on price, quality, type of service and coverage without the inconvenience and expense of having to take a new number when moving between providers. </li></ul><ul><li>Nigeria has adopted it for its ability to jerk up quality of service in the belief that Operators would not want to loose customers </li></ul><ul><li>  Number portability also eliminates the need for callers to contact directory services to find someone's new number or for people to miss calls as callers continue to dial the old number. </li></ul><ul><li>NCC has directed that Number Portability will first be implemented between Mobile Operators MNP, and then between Fixed Line Operators, FNP. Bimodal NP ( Mobile to fixed or Fixed to Mobile) will not be implemented at this time. </li></ul><ul><li>Nigeria I yet to issue a firm regulation on the subject but an Initial Consultation Paper has been issued. </li></ul>
  66. 66. LOCAL NUMBER PORTABILITY, LNP <ul><li>Under Local Number Portability rules, you can switch telephone service providers within the same geographic area and keep your existing phone number. However, if you are moving from one geographic area to another, you may not be able to take your number with you. In addition to switching from one wireless company to another, in most cases, you will be able to switch from a wireline company to a wireless company, or from a wireless company to a wireline company, and still keep your phone number. </li></ul>
  67. 67. Mobile Number Portability, MNP <ul><li>Mobile number portability (MNP) covers all digital mobile service numbers irrespective of the technology used (GSM or CDMA networks) except for satellite-only mobile services, GMPCS(Global Mobile Personal Communication by Satellite). </li></ul>
  68. 68. FEES AND CHARGES under Number Portability <ul><li>Telephone Operators are allowed to charge a fee to recover their number porting costs. Companies may or may not choose to charge a fee, and their fees may vary. If they do charge specific fees, the fees cannot exceed their porting costs which may be regulated. Local telephone companies that assess the fee generally charge a fixed monthly fee and may do so for up to five years </li></ul>

  106. 107. Describe how digital system functions in a typical TV transmission
  107. 108. Digital system in TV transmission <ul><li>DIGITAL TECHNOLOGY breaks your voice (or television) signal into binary code—a series of 1s and 0s—transfers it to the other end where another device (phone, modem or TV) takes all the numbers and reassembles them into the original signal. The beauty of digital is that it knows what it should be when it reaches the end of the transmission. That way, it can correct any errors that may have occurred in the data transfer. The result is: clarity of the signal. In most cases, you'll get distortion-free conversations, clearer TV pictures, and in advanced applications, increased features and applications. </li></ul>
  108. 109. What does VOICE OVER INTERNET PROTOCOL, VoIP, mean?
  109. 110. VoIP <ul><li>Ordinarily, telephone communication is the movement of ‘voice electrons’ through the PSTN. We thought voice electrons could not transmit in an IP communication channel until research proved otherwise. Namely that in an IP Communication channel everything is transmitted as data. An IP ‘pipe” is an Ethernet-data-only pipe. Hence the carrying of voice over an IP pipe (VoIP) or the carrying of video over an IP pipe (ViIP). Wherever there is an IP inlet/outlet, voice communication is possible, and so the breakthrough of Voice over Internet Protocol, VoIP. </li></ul><ul><li>H.323 </li></ul><ul><li>Since VoIP is based on open standards, H.323, its application and development has been enhanced by improvements in technologies related to those standards </li></ul>

  120. 121. What is convergence <ul><li>Convergence may mean many things depending on the subject under which it is being discussed. </li></ul><ul><li>The ultimate for society is economic convergence </li></ul><ul><li>But here we should be talking of technological ( in fact telecommunications) convergence </li></ul><ul><li>Today, we are surrounded by a multi-level convergent media world where all modes of communication and information are continually reforming to adapt to the enduring demands of technologies, “changing the way we create, consume, learn and interact with each other ” </li></ul>
  121. 122. Convergence in telecommunications <ul><li>Convergence in telecommunications refers to the combination of multiple services through lines of telecommunication from a single provider. </li></ul><ul><li>In the past we used to go to operators to ask for telephone service, returned to request for internet as another service, and later returned to go for yet another separate service. </li></ul><ul><li>Today the moment we want service all of the services are given to us in a converged sense. </li></ul>
  122. 123. What is meant by Converged Systems
  123. 124. Converged Systems <ul><li>Converged technology is when different systems tend towards performing similar functions. </li></ul><ul><li>We used to have telephones that only made us talk, calculators that did arithmetic for us, clocks that kept us abreast of time and gramophone that played music for us. </li></ul><ul><li>What does all of the above together today is a telephone handset and it is the simplest form of technology convergence. </li></ul>
  124. 125. Another look at Converged Systems <ul><li>Converged systems are networks based on the Internet Protocol to carry voice, video, and data, as against the traditional system that is circuit switched. </li></ul><ul><li>IP networks are packet switched. In the early days of converged networks, voice calling on IP networks were uneven; however, the quality of service on IP networks are improving daily, with the high-capacity routers, switches, and dense wavelength multiplexing fibre-optic equipment now being deployed. </li></ul>

Broadcast medium: a medium that disseminates via telecommunications </li></ul><ul><li>3. Broadcasting is the distribution of audio and video signals (programs) to a number of recipients (&quot;listeners&quot; or &quot;viewers&quot;) that belong to a large group. This group may be the public in general, or a relatively large audience within the public. Thus, an Internet channel may distribute text or music world-wide, while a public address system in (for example) a workplace may broadcast very limited ad hoc soundbites to a small population within its range. </li></ul><ul><li>4. Broadcasting is the process of sending the same e-mail message to multiple recipients at the same time. </li></ul><ul><li>5. Historically, &quot;broadcasting&quot; referred to the activity of radio and television stations. As cable, satellite and the Internet have developed, it is often used to describe the simultaneous real-time distribution of any media from one source to many recipients, using any transport method. </li></ul><ul><li>6. Broadcasting refers to content carried over air waves. Usually designed to appeal to a broad audience segment. </li></ul>

  131. 132. Describe Mobile Technologies and Their Generations
  132. 133. 1G <ul><li>The first generation of systems for mobile telephony was analog, circuit switched, and it only carried voice traffic. The analog phones used in 1G were less secure and prone to interference where the signal is weak. </li></ul><ul><li>Analog systems include AMPS, NMT and ETACS. </li></ul>
  133. 134. 2G <ul><li>The second generation of mobile telephony systems uses digital encoding. 2G networks support high bit rate voice, limited data communications and different levels of encryption. 2G networks include GSM, D-AMPS (TDMA) and CDMA. 2G networks can support SMS applications. </li></ul>
  134. 135. Describe GPRS
  135. 136. Two descriptions will be offered <ul><li>The first Description </li></ul>
  136. 137. GPRS ( First Description) <ul><li>General Packet Radio Service (GPRS) is a packet oriented Mobile Data Service(with data rates from 56 up to 114 kbit/s) available to users of the 2G cellular communication systems Global System for Mobile Communications (GSM), as well as in the 3G systems. In the 2G systems. </li></ul><ul><li>GPRS data transfer is typically charged per megabyte of traffic transferred, while data communication via traditional circuit switching is billed per minute of connection time, independent of whether the user actually is using the capacity or is in an idle state. GPRS is a best-effort packet switched service, as opposed to circuit switching, where a certain Quality of Service (QoS) is guaranteed during the connection for non-mobile users. </li></ul>
  137. 138. GPRS (contd..) <ul><li>2G cellular systems combined with GPRS are often described as &quot;2.5G&quot;, that is, a technology 'somewhere between' the second (2G) and third (3G) generations of mobile telephony. It provides moderate speed data transfer, by using unused Time division multiple access (TDMA) channels in, for example, the GSM system. Originally there was some thought to extend GPRS to cover other standards, but instead those networks are being converted to use the GSM standard, so that GSM is the only kind of network where GPRS is in use </li></ul>
  138. 139. 2 nd description of GPRS <ul><li>General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones. Although GSM is strictly a 2G standard, that GPRS is an enhancement of it makes it code named a 2.5G generation of mobile phones. </li></ul><ul><li>GPRS, which supports a wide range of bandwidths, is an efficient use of limited bandwidth and is particularly suited for sending and receiving small bursts of data, such as e-mail and Web browsing, as well as large volumes of data. </li></ul>
  139. 140. 2.5G <ul><li>2.5G extends 2G systems, adding features such as packet-switched connection and enhanced data rates. 2.5G networks include EDGE and GPRS. These networks support WAP, MMS, SMS mobile games, and search and directory. </li></ul>
  140. 141. 2.5G (continued) <ul><li>One of the major limitations of second generation cellular communications systems is that data can only be transferred after a connection has been established. This is inefficient if only small amount of data is transferred, and in situations where data is transferred in bursts. 2.5G cellular systems allow a mobile station to be &quot;always-online&quot; for sending and receiving packet data. This allows efficient transfer of small amounts of data, without the overhead of establishing a connection for each transfer. It also efficiently supports bursty data transfers, avoiding the need to allocate capacity to a connection that cannot be reallocated by the network if the connection chooses not to use it. The two major forms of 2.5G enhancements to second-generation cellular systems are the General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE). </li></ul><ul><li>Some GSM networks support the General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE). </li></ul>

What is special to 3G <ul><li>Unlike IEEE 802.11 networks, which are commonly called Wi-Fi or WLAN networks, 3G networks are wide-area cellular telephone networks that evolved to incorporate high-speed Internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data. </li></ul>
  148. 149. Why is Nigeria regarded as ready for 3G?
  149. 150. Because: <ul><li>High uptake of services in 3G is expected </li></ul><ul><li>There is Lack of broadband internet services due to low penetration of copper/DSL. </li></ul><ul><li>There is a pressing need to bridge digital divide. </li></ul><ul><li>Nigerians are mobile people. </li></ul><ul><li>It is cheaper and quicker to roll-out 3G/WCDMA than to run communication cables to every home </li></ul>
  150. 151. Wideband Code Division Multiple Access (WCDMA) <ul><li>Wideband CDMA, also known as UMTS in Europe, is 3G standard for GSM in Europe, Japan and the United States. It's also the principal alternative being discussed in Asia. It supports very high-speed multimedia services such as full-motion video, Internet access and video conferencing. It uses one 5 MHz channel for both voice and data, offering data speeds up to 2 Mbps. </li></ul>
  151. 152. Describe Code Division Multiple Access (CDMA) <ul><li>A digital wireless technology that uses a spread spectrum technique to scatter a radio signal across a wide range of frequencies. CDMA is a 2G technology. WCDMA, a 3G technology, is based on CDMA. </li></ul><ul><li>CDMA has multiple variants, including CDMA 1X, cdma2000, CDMA2000 1X, CDMA2000 1xEV-DO and cdmaOne. </li></ul>
  152. 153. What is WAP?
  153. 154. WAP <ul><li>It means Wireless Application Protocol, a secure specification that allows users to access information instantly via handheld wireless devices such as mobile phones, pagers, two-way radios, smartphones and communicators. </li></ul><ul><li>WAP supports most wireless networks namely CDMA, GSM, etc </li></ul>
  154. 155. Explain Symmetric Transmission and Asymmetric Transmission
  155. 156. Data transmission is symmetric if the data in the downlink and the data in the uplink is transmitted at the same data rate. This will probably be the case for voice transmission - the same amount of data is sent both ways. However, for internet connections or broadcast data (e.g., streaming video), it is likely that more data will be sent from the server to the mobile device (the downlink). That is asymetric.
  156. 157. What is EVDO <ul><li>It is the acronym for Evolution Data Only. Some say it is Evolution Dada Optimized. Point is: both are definitions and definitions are never wrong. It practically means you can have wireless broadband internet access at 500K – 800k speed to your Windows, Mac OS X, or Linux laptop by inserting an EVDO Card into your laptop. Your service provider must have provided a coverage to your area before you can use the resource. And you have to log in with propriety parameters which only your service provider will supply. It is a recent technology. As recent as 2005. </li></ul><ul><li>Talking technology, EVDO is based on the 1xRTT standard, which is available in almost all cell phone coverage areas and provides Internet speeds of about 2-3 times that of dial-up (about 60K-100K). If you go out of the 1xEVDO broadband coverage zone, you will automatically be switched onto the 1xRTT standard, which means that you can still access the Internet almost anywhere your travels take you. </li></ul>
  157. 158. Telecom Engineering Questions & Answers

The computer is digital so the conversion is necessary. </li></ul>
  164. 165. What is meant by Latency
  165. 166. Latency Latency means delay. It may also be the period of time that one component in a system is spinning its wheels waiting for another component. Latency, therefore, is wasted time. For example, in accessing data on a disk, latency is defined as the time it takes to position the proper sector under the read/write head. In networking, the amount of time it takes a packet to travel from source to destination. Together, latency and bandwidth define the speed and capacity of a network.

  176. 177. Wireless Systems
  177. 178. Types of Wireless Systems <ul><li>There are three types of wireless systems in common use today: </li></ul><ul><li>Fixed wireless. </li></ul><ul><li>Here you have two wireless antennas, one each at the sending (your institution) and receiving institutions acting much like a cable connected between the two. You may need to erect masts to hold the antennas as this system requires that you have a clear path or line-of-sight between the two institutions, as the connection is degraded if the path is blocked by trees, building, other infrastructure or hills. Fixed wireless systems can provide connection between two locations up to 30 km apart. </li></ul>
  178. 179. Types of Wireless Systems <ul><li>WIFI </li></ul><ul><li>Wireless Fidelity or WIFI systems were designed primarily for local area networks (with ranges of 100 meters or a little more) but can be used to provide coverage over relatively large areas by using enough access points to create overlapping cells of coverage or what are called “hot spots”. WIFI can be used to provide connectivity from your VSAT across your entire institution say throughout the school or hospital grounds. </li></ul><ul><li>With mobile devices such as laptop computers equipped with the right access card, you can create a truly mobile access environment where people can connect anywhere, anytime within the hot spots. The distinct advantage of WIFI is that you do not need line-of-sight operation. </li></ul>
  179. 180. Broadband Wireless Systems <ul><li>WIMAX </li></ul><ul><li>Worldwide Interoperability for Microwave Access or WIMAX is a newer access technology that combines the functionality of fixed wireless and WIFI. It is meant to provide WIFI like features at much longer distances . </li></ul><ul><li>WIMAX is heralded as the solution to cost effectively offering connectivity coverage over large areas especially in the metropolitan </li></ul>
  180. 181. From Dial Up to MiMAX <ul><li>Dial-up access – Dial up is when one uses a connected access to a service provider. It may be fixed or wireless. They are mostly wireless these days. The fixed are either via DSL cable or fibre if broadband were to be offered. Of course copper cable also do but with poor results. </li></ul><ul><li>  If you are still using dial-up, chances are that either broadband access is not available or that broadband access is too expensive. </li></ul>
  181. 182. WiFi access – <ul><li>In the home, you may have set up a WiFi router that lets you surf the Web while you lounge with your laptop. On the road, you can find WiFi hot spots in restaurants, hotels, coffee shops and libraries. Some may even sneak into your house and if they are not protected you may be using them as free internet access </li></ul><ul><li>The main problem with WiFi access is that hot spots are very small, so coverage is sparse </li></ul>
  182. 183. Broadband Internet Access <ul><li>The main problem with broadband access is that it is expensive and it doesn't reach all areas. </li></ul><ul><li>  WimAx solves the problem </li></ul><ul><li>WiMAX is short for Worldwide Interoperability for Microwave Access, and it also goes by the IEEE name 802.16. </li></ul>
  183. 184. WIMAX provides <ul><li>High speed of broadband service </li></ul><ul><li>Wireless rather than wired access, so it would be a lot less expensive than cable or DSL and much easier to extend to suburban and rural areas </li></ul><ul><li>Broad coverage like the cell phone network instead of small WiFi hotspots </li></ul><ul><li>WiMAX has the potential to do to broadband Internet access what cell phones have done to phone access </li></ul><ul><li>It is likely Mimax will replace cable, DSL etc in the way Mobile phones have replaced our old land lines. </li></ul>
  184. 185. Wimax Completely Described now <ul><li>WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless &quot;metropolitan area networks&quot;. WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m) </li></ul>
  185. 186. Wimax ..contd <ul><li>With WiMAX, WiFi-like data rates are easily supported, but the issue of interference is lessened. WiMAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers. </li></ul><ul><li>  WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol. WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances . </li></ul>
  186. 187. Wimax ..cond. <ul><li>The IEEE 802.16 standard defines the technical features of the communications protocol. The WiMAX Forum offers a means of testing manufacturer's equipment for compatibility, as well as an industry group dedicated to fostering the development and commercialization of the technology. </li></ul><ul><li>  WiMax.com provides a focal point for consumers, service providers, manufacturers, analysts, and researchers who are interested in WiMAX technology, services, and products. </li></ul>

They are usually in the switches and generally not in transmission systems </li></ul>
  206. 207. How do we integrate Voice & Data?
  207. 208. Voice & Data <ul><li>Voice is very important; Data is very critical: </li></ul><ul><li>The traditional system is circuit switched; may carry voice, data, video piece meal but converged systems do so in packets based on IP protocol. </li></ul><ul><li>Packet switching relates to unique identification of coded message and retrieving same in unique delay permissible ways at the destination. </li></ul><ul><li>Packets are independent with multiple packets in a stream often traversing the network from its originating point to a destination nodes by different routes </li></ul>
  208. 209. What is Packet Switching in reality?
  209. 210. Packet Switching <ul><li>In converged networks, the vocabulary of hierarchy in switching exchanges is de-emphasized </li></ul><ul><li>Latency factor is a fact of life in packet switching </li></ul><ul><li>Packet switching is the platform on which the Internet works </li></ul><ul><li>Packet switching was designed for data but with the coming of The Internet, it is now being used for voice & Video </li></ul>
  210. 211. Circuit Switching vs. Packet Switching
  211. 212. Circuit Switching Traditional connections for voice communications require a physical path connecting the users at the two ends of the line, and that path stays open until the conversation ends. This method of connecting a transmitter and receiver by giving them exclusive access to a direct connection is called circuit switching.
  212. 213. Packet Switching <ul><li>Most modern networking technology is radically different from this traditional model because it uses packet data. Packet data is information which is: </li></ul><ul><ul><ul><li>chopped into pieces (packets), </li></ul></ul></ul><ul><ul><ul><li>given a destination address, </li></ul></ul></ul><ul><ul><ul><li>mixed with other data from other sources, </li></ul></ul></ul><ul><ul><ul><li>transmitted over a line with all the other data, </li></ul></ul></ul><ul><ul><ul><li>reconstituted at the other end. </li></ul></ul></ul><ul><ul><ul><li>Packet-switched networks chop the telephone conversation into discrete &quot;packets&quot; of data like pieces in a jigsaw puzzle, and those pieces are reassembled to recreate the original conversation. </li></ul></ul></ul><ul><li>Packet data was originally developed as the technology behind the Internet </li></ul>
  213. 214. The Packet, Payload, Header etc
  214. 215. The Data packet. The major part of a packet's contents is reserved for the data that is meant for transmission. This part is called the PAYLOAD. In general, the data to be transmitted is arbitrarily chopped-up into payloads of the same size. At the start of the packet is a smaller area called a HEADER. The header is vital because the header contains the address of the packet's intended recipient. This means that packets from many different phone users can be mixed into the same transmission channel, and correctly sorted at the other end. There is no longer a need for a constant, exclusive, direct channel between the sender and the receiver.
  215. 216. What is VoIP?
  216. 217. VoIP <ul><li>Voice over Internet protocol is the technology of transmitting voice over a data network using IP </li></ul><ul><li>Although VoIP is the more popularly know there are other technologies used in transmitting voice.
