1. A modern smart phone is a combination of many different devices. What devices does it replace?

2. Here are definitions of the term “convergence”. Read and translate them.

1. Technological convergence is the tendency for different technological systems to evolve toward performing similar tasks. 

2. Digital convergence refers to previously separate technologies such as voice (and telephony features), data (and productivity applications) and video that now share resources and interact with each other.

3. Convergence is defined more specifically as the coming together of telecommunications, computing and broadcasting into a single digital bit-stream. 

3. Here are the words and word combinations you have to learn.

Apply, arise, artificial intelligence, connection, converge, convergence, convergent, deliver, distinct, emerge, emergence, explore, fixed and mobile operators, historical roots, inspire, joined product, market, multi-level, multiple, permit, rise, service, single, singularity, surround, trace back

4. Read the text and find more definitions of convergence.

Telecommunications convergence

Communication networks were designed to carry different types of information independently. Radio was designed for audio, and televisions were designed for video. The older media, such as television and radio, are broadcasting networks with passive audiences. Convergence of telecommunication technology permits the manipulation of all forms of information, voice, data, and video. Telecommunication has changed from a world of scarcity to one of seemingly limitless capacity.

The historical roots of convergence can be traced back to the emergence of mobile telephony and the Internet. The term properly applies only from the point in marketing history when fixed and mobile telephony began to be offered by operators as joined products. Fixed and mobile operators were, for most of the 1990s, independent companies. Even when the same organization marketed both products, these were sold and serviced independently.

The rise of digital communication in the late 20th century has made it possible for media organizations (or individuals) to deliver text, audio, and video material over the same wired, wireless, or fiber-optic connections. At the same time, it inspired some media organizations to explore multimedia delivery of information. Today, we are surrounded by a multi-level convergent media world where all modes of communication and information are continually reforming, changing the way we create, consume, learn and interact with each other. Convergence in this instance is defined as the interlinking of computing and other information technologies, media content, and communication networks arisen as the result of the evolution and popularization of the Internet as well as the activities, products and services that have emerged in the digital media space.

Telecommunications convergence, network convergence or simply convergence are broad terms used to describe emerging telecommunications technologies, and network architecture used to migrate multiple communications services into a single network. Specifically this involves the converging of previously distinct media such as telephony and data communications into common interfaces on single devices, such as most smart phones that can make phone calls and search the web.

Also included in this topic is the basis of computer networks, wherein many different operating systems are able to communicate via different protocols. This could be the first step to artificial intelligence networks on the Internet eventually leading to a powerful superintelligence via a technological singularity.

I - Were they popular among our population?

D - At first. But people are always wanting to upgrade and get the latest models or new gadgets.

I - Are you going to adapt to your customers' needs?

D - We have to, if we want to remain in business. But it is not easy. I went to a technology fair last week and they were demonstrating this jacket and hat that was your phone.

I - Amazing!

D - Yeah, there are so many disruptive technologies, I don't know what is going to happen.

I - Can you make a guess?

D - Maybe we'll have to get into clothing.

24. Using the dialogue above, make up your own dialogue between a TV broadcaster and an interviewer. Use the following text to help you.

TV broadcaster

A lot of broadcasters like us are having a hard time. The problem is that there are lots more channels these days and people also get them through different media. I can download the latest films from the phone company. My children don't even watch TV. They watch video online and their friends send them clips on their mobiles. But we have to survive on our advertising revenue and at the moment that's falling. Things are really not easy, and I'm sure there are some broadcasters that will go out of business.

25. Read and learn another dialogue.

Fixed Telecommunications Networking Provider (F) and interviewer (I)

I - What do you do?

F - We own the fixed telecoms network.

I - How are you doing these days?

F - We've seen a big fall in revenues from voice calls.

I - Oh dear, why is that?

F - Because everything is IP now.

I - Yeah, right. You must be having hard times now.

F - In fact we are now in a great position.

I - Why?

F - Because we are putting intelligence into our network.

I - Could you explain what it means for your company, please?

F - Yeah, sure, it can become an enormous computer, capable of delivering applications.

I - It sounds interesting. Are you sure this new invention will meet your customers' needs? Are you sure they will have all the necessary equipment for that?

F - Absolutely. All our customers need is a broadband pipe into our network cloud and we act as an IT utility - and most people have already got that with an ordinary phone line.

I - You seem to have thought of everything for it to have a success.

F - Of course, it easily makes up for the money from traditional voice calls.

I - Really? What will you do then with the new capabilities?

Convergence technologies and services

Convergence services, such as VoIP, IPTV, Mobile TV, Smart TV, etc., replace the old technologies and are a threat to the current service providers. IP-based convergence is inevitable and will result in new service and new demand in the market. When the old technology converges into the public-owned common, IP based services become access-independent or less dependent. The old service is access-dependent.

Convergent technologies can integrate the fixed-line with mobile to deliver convergent solutions. Recent examples of new, convergent services include:

Video on demand (vod)

Video on demand (VOD) or audio and video on demand (AVOD) are systems which allow users to select and watch/listen to video or audio content when they choose to, rather than having to watch at a specific broadcast time. IPTV technology is often used to bring video on demand to televisions and personal computers.

Fixed-mobile convergence

Fixed–mobile convergence (FMC) is a change in telecommunications that removes differences between fixed and mobile networks. Fixed Mobile Convergence is a transition point in the telecommunications industry that will finally remove the distinctions between fixed and mobile networks, providing a superior experience to customers by creating seamless services using a combination of fixed broadband and local access wireless technologies to meet their needs in homes, offices, other buildings and on the go.

Mobile-to-mobile convergence

Mobile to mobile convergence (MMC) is a term to describe a technology used in modern computing and telephony. The term is an offshoot of fixed mobile convergence (FMC) and uses dual mode (cellular network and Wi-Fi) phones with a special software client and an application server to connect voice calls and business applications via a VoWLAN and/or through a cellular service.

Convergent technologies include:

Ip Multimedia Subsystem

The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an architectural framework for delivering IP multimedia services. 

Session Initiation Protocol

Session Initiation Protocol (SIP) is a standardized set of formats for communicating messages used to initiate, control, and terminate interactive user sessions with multimedia services such as Internet telephone calls, video conferencing, chat, file transfer, and online games.


Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over a packet-switched network such as a LAN or the Internet, instead of being delivered through traditional terrestrial, satellite signal, and cabletelevision formats.

Voice over ip

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

Digital video broadcasting – handheld

DVB-H (Digital Video Broadcasting - Handheld) is one of three prevalent mobile TV formats. It is a technical specification for bringing broadcast services to mobile handsets.

28. Using the information above work in pairs. You are going to compare convergent services with traditional ones. Use the key words and phrases to help you. You may draw pictures and diagrams to explain your point.

Mobile Devices

Tablet computers

Like laptops, tablet computers are designed to be portable. However, they provide a different computing experience. The most obvious difference is that tablet computers don't have keyboards or touchpads. Instead, the entire screen is touch-sensitive, allowing you to type on a virtual keyboard and use your finger as a mouse pointer.

Tablet computers are mostly designed for consuming media, and they are optimized for tasks like web browsing, watching videos, reading e-books, and playing games. For many people, a "regular" computer like a desktop or laptop is still needed in order to use some programs. However, the convenience of a tablet computer means it may be ideal as a second computer. Below are some of the main features you can expect with a tablet computer:

Mobile OS: Different types of tablets use different operating systems. Examples include Android and iOS. You'll usually be able to download free updates to your OS as they become available.

Solid-state drives: Tablet computers usually use solid-state drives, which allow the computer to boot up and open programs more quickly. They are also more durable than hard disk drives.

Wi-Fi and 3G/4G: Because they are optimized for Internet use, tablet computers have built-in Wi-Fi. For a monthly fee, you can also purchase a 3G or 4G data plan, allowing you to access the Internet from almost anywhere.

Bluetooth: In order to save space, tablet computers have very few ports. If you want to use an external keyboard or other peripherals, they will often use a wireless Bluetooth connection.

E-book readers

E-book readers (also called e-readers) are similar to tablet computers, except they are mainly designed for reading e-books (digital, downloadable books). Examples include the Amazon Kindle and Barnes & Noble Nook.

E-book readers have either an e-paper display or an LCD:

E-paper: Short for electronic paper, this type of display can usually only display in black and white. It is designed to look a lot like an actual page in a book. Unlike an LCD, it is not backlit, so the text stays readable even outdoors in full sun. Many people consider e-paper to be more pleasant to read because it causes less eye strain. However, it generally can't be used for videos or other applications because the refresh rate is too low.

LCD: This is the same type of screen found on tablet computers and laptops. It's more versatile than e-paper, but it's often more difficult to view in bright sunlight, as the image becomes washed out. Since an LCD screen can display colors, this type of e-reader is better for viewing magazines or books with photos. Many LCD e-readers (such as the Nook Color) are basically tablet computers, as they can perform many different tasks in addition to displaying e-books.

You don't need an e-reader to read an e-book. E-books can usually be read on tablet computers, smartphones, laptops, and desktops.


A smartphone is a powerful mobile phone that is designed to run a variety of applications in addition to providing phone service. Smartphones are basically small tablet computers, and they can be used for web browsing, watching videos, reading e-books, playing games, and more.

Smartphones use touch screens and operating systems similar to those used by tablet computers. Many of them use a virtual keyboard, but others have a physical keyboard, which allows the entire screen to be used for display purposes.

Internet access is an important feature of smartphones. Generally, you will need to purchase a 3G or 4G data plan in addition to normal cell service. Smartphones can also connect to Wi-Fi when it is available; this allows you to use the Internet without using up your monthly data allotment.

A personal digital assistant (PDA) is a mobile device that is used for managing phone numbers, addresses, calendars, and other information. Before smartphones existed, a PDA was usually a separate device. Today, smartphones combine the functionality of a PDA and a mobile phone.

S – Hello, how can I help you?

C – Hi, I'd like to buy a new computer. But there are so many types. It is hard for me to choose. Can you help me with that please?

S – Sure, first, I would like you to answer a few questions. Do you prefer a desktop computer, laptop or tablet?

C – I don't know, really, what is the difference between them?

S – Well, tablets are portable and have touch-sensitive screen, whereas desktop computers have keyboards or touch-pads.

C – Touch-sensitive screen? What does it mean?

S – It's kind of a virtual keyboard. It means that you will use your fingers when typing in.

C – WOW, it sounds amazing.

S – What kinds of tasks do you need to do on your PC?

C – Well, I usually watch movies, surf the Web, play computer games and read a lot of books.

S – Good! It means that a tablet computer is ideal for your needs whereas a desktop computer or laptop are needed for other types of programs.

C – Good! I really need it for those tasks. My old PC opened programs very slowly. What about a tablet computer?

S – It definitely works faster, since tablets use solid-state drives. Whereas desktop computers use hard disk drives which are less durable than solid-state ones.

C – Cool! You know I am a student and it is very important for me to be able to carry it with me easily every day.

S – So in this case a tablet is perfect for you. It's lighter than a laptop and a desktop computer.

C – Great, because it is not very convenient only being able to access my files at home. So I want a tablet then. But I need to choose the right tablet.

S – Sure, There are several types of tablets with different operating systems. For example, iOS or Android are the most common types of them. What would you prefer?

C – I am not sure I know the difference between them. Can you explain it to me please?

S – Sure. Most Android-based tablets are produced by Samsung, a Korean company whereas iOS-based devices are made by Apple. Apple devices provide you with less free applications than Samsung ones do. So I'd go for Samsung tablet.

C – I'd like to buy Samsung tablet then. I wonder what other features I can find on tablet computers?

S – All the tablets are Wi-Fi- and 3G-enabled.

C – Awesome/Cool! By the way, I have heard that tablets do not have a lot of ports. Is it true?

S – Unfortunately, it is true, but they do have Bluetooth, that can allow you to connect any peripheral device wirelessly.

C – Great! What model would you recommend?

S – Well, this one is the latest and have all the features you need for your tasks. So it would be worth getting Samsung ST530.

C – Cool! I'll take it. Thank you for your help.

S – You are welcome.

25. Learn the dialogue between a sales assistant and a customer.

S – Hello, how can I help you?

C – I need some suggestions on updating my mobile technology.

S – Can you tell me what you use at the moment? I am sure I'll be able to recommend something appropriate.

C – Well, I am a technology student. I've got an old desktop computer and GSM phone. The problem is that I'm on the move so much. It's not very convenient only being able to access my information when I am at my dormitory. And it is impossible for me to carry my PC every day.

S – Oh, I see. What kinds of tasks do you need to be able to do when you are away from home?

C – Well, I want the basic functionality of my phone and desktop computer. I want to make and receive voice calls and voice mail. I send and receive emails all the time and sometimes I need to be able to read the attachments. I also need to download large files for my studies. I would also like to update my calendar on a daily basis. I usually watch movies, surf the Internet, read books online and play computer games. I'd like to be able to do all these things on the move.

S - OK, well, what I'd recommend is that you have a hand-held device such as a smartphone. How much weight do you want to carry around?

C – I don't mind carrying around something a bit heavier as long as I can do everything I need to do.

S – How often do you create documents when you are on the move?

C - I often have to create or amend documents or presentations when I am on the move, that's important to me.

S – So I'd go for Super Mob 360 phone which is GSM- and GPRS-enabled for voice, data, and location-based services. It acts as a PDA and a mobile phone. It's also Wi-Fi and 4G- enabled, So you can surf the Net whenever you want.

C – It's fantastic! What else can I do with it?

S -You can use your fingers when typing in since most smartphones have touch screens. Not only can they provide you with phone calls but also they can run a lot of applications. So you can find it useful in your studies and game playing.

C – It's wonderful. But can I use a physical keyboard?

S – Sure. Some smartphones do have physical keyboards. Would you like to buy one?

C – I wouldn't. Can I have a smartphone with touch screen, but use a peripheral device if I want to later?

S – Of course. Super Mob 360 is Bluetooth-enabled, so you can connect any peripheral device wirelessly.

C – 'Wow, that sounds great! I'd like to buy this smartphone please.

S – Great! I'll check on the system to see if we have it in stock. One second please. Yeah, we have it in stock. Go to a checkout. I'll bring it to you in a minute.

Location-based services

Location-based services (LBS) are a general class of computer program-level services that use location data to control features. As such LBS is an information service and has a number of uses in social networking today as an entertainment service, which is accessible with mobile devices through the mobile network and which uses information on the geographical position of the mobile device. This has become more and more important with the expansion of the smartphone and tablet markets as well.

LBS include services to identify a location of a person or object, such as discovering the nearest banking cash machine (a.k.a. ATM) or the whereabouts of a friend or employee. LBS include parcel tracking and vehicle tracking services. LBS can include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. They include personalized weather services and even location-based games. They are an example of telecommunication convergence.

LBS include applications that depend on the user location to provide a service/information that is relevant to the user at that location. LBS normally use mobile devices with positioning ability to provide the service or information to the user. LBS can be used for personal or professional purposes.

Several categories of methods can be used to find the location of the subscriber. The simple and standard solution is GPS-based LBS.  GPS is based on the concept of trilateration, a basic geometric principle that allows finding one location if one knows its distance from other, already known locations.

GSM localization is the second option. Finding the location of a mobile device in relation to its cell site is another way to find out the location of an object or a person. It relies on various means of multilateration of the signal from cell sites serving a mobile phone. The geographical position of the device is found out through various techniques like time difference of arrival (TDOA) or Enhanced Observed Time Difference (E-OTD).

Many other Local Positioning Systems are available, especially for indoor use. GPS and GSM do not work very well indoors, so other techniques are used, including Co-Pilot Beacon for CDMA Networks, Bluetooth, UWB, RFID and Wi-Fi.

Some examples of location-based services are:

  • Recommending social events in a city;

  • Requesting the nearest business or service, such as an ATM, restaurant or a retail store;

  • Turn by turn navigation to any address;

  • Assistive Healthcare Systems;

  • Locating people on a map displayed on the mobile phone

  • Receiving alerts, such as notification of a sale on gas or warning of a traffic jam;

  • Location-based mobile advertising;

  • Asset recovery combined with active RF to find, for example, stolen assets in containers where GPS would not work;

  • Сontextualizing learning and research;

  • Games where your location is part of the game play, for example your movements during your day make your avatar move in the game or your position unlocks content;

  • Real-time Q&A revolving around restaurants, services, and other venues.

27. Give a short summary of the text above.

28. What kind of LBS are useful for…

- drivers?

- gamers?

- tourists?

- ordinary people?



1. Read the text about the concept of Global Network Infrastructure.

A global network is any communication network which spans the entire Earth, and global span was achieved in 1899. The telephony network was the second to achieve global status, in the 1950s. More recently, interconnected IP networks (principally the Internet, with estimated 2.5 billion users worldwide in 2014), and the GSM mobile communication network (with over 6 billion worldwide users in 2014) form the largest global networks of all.

Setting up global networks requires immense, costly and lengthy efforts lasting for decades. Elaborate interconnections, switching and routing devices, laying out physical carriers of information, such as land and submarine cables and earth stations must be set in operation. In addition, international communication protocols, legislation and agreements are involved.

  1. Answer the questions.

1. How many global networks exist nowadays?

2. Which of the established networks is nearly out of use, and why?

3. Which of the global networks is the most used one?

4. What steps are necessary to set up a global network?

5. Why does it take decades to set up a global network?

Telecommunications network structure

A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals. The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal.

Each terminal in the network usually has a unique address, so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space.

Examples of telecommunications networks are:

computer networks

the Internet

the telephone network

the global Telex network

telephone network is a telecommunications network used for telephone calls between two or more parties. There are a number of different types of telephone network:

  • A landline network where the telephones must be directly wired into a single telephone exchange. This is known as thepublic switched telephone networkor PSTN.

  • A wireless network where the telephones are mobileand can move around anywhere within thecoverage area.

  • A private network where a closed group of telephones are connected primarily to each other and use a gateway to reach the outside world. This is usually used inside companies and call centers and is called a private branch exchange (PBX).

Public telephone operators(PTOs) own and build networks of the first two types and provide services to the public under license from the national government.Virtual Network Operators(VNOs) lease capacity wholesale from the PTOs and sell ontelephonyservice to the public directly.

The public switched telephone network (PSTN) is the aggregate of the world's circuit-switched telephone networks that are operated by national, regional, or local telephony operators, providing infrastructure and services for public telecommunication. The PSTN consists of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables, all interconnected by switching centers, thus allowing any telephone in the world to communicate with any other. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital in its core network and includes mobile and other networks, as well as fixed telephones.

The technical operation of the PSTN adheres to the standards created by the ITU-T. These standards allow different networks in different countries to interconnect seamlessly. The E.163 and E.164 standards provide a single global address space for telephone numbers. The combination of the interconnected networks and the single numbering plan make it possible for any phone in the world to dial any other phone.

wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks.

cellular network or mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as acell siteorbase station. In a cellular network, each cell characteristically uses a different set of radio frequencies from all their immediate neighboring cells to avoid any interference.

When joined together these cells provide radio coverage over a wide geographic area. This enables a large number of portable transceivers (e.g., mobile phones, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.

Although originally intended for cell phones, with the development of smartphones,cellular telephone networksroutinely carry data in addition to telephone conversations.

Global System for Mobile Communications (GSM): The GSM network is divided into three major systems: the switching system, the base station system, and the operation and support system. The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred to where it needs to go. GSM is the most common standard and is used for a majority of cell phones.
