3. Term Definition
Multimedia = integration of multiple forms of media. This
includes text, graphics, audio, video, etc
Telecommunications = the exchange of
information over significant distances by electronic means.
Network = collection of terminals, links and nodes which
connect together to enable telecommunication

19. Mini Discussion
Imagine that you are the top
management of a telecom company.
What are the important UPs and
DOWNs which will impact your
business in the future?
Telecommunication Channelatmosphere for sound communications, glass optical fibers for some kinds of optical communications, coaxial cables for communications by way of the voltages and electric currents in them, andfree space for communications using visible light, infrared waves, ultraviolet light, and radio waves.Â
Technologies in fixed wire lineAnalog 56 Kbps â Analog normally known as dial-up internet which is used through normal telephone system and that is the time where internet was introduced to the world.ISDN 128 Kbps â Later Integrated Services Digital Network (BRI) connections are delivered over the same telephone cable with 128 Kbps speed.ADSL 256 Kbps - Asymmetric Digital Subscriber Line technology which was commonly reffered as the first broadband connectivity over copper wire.ADSL Lite 1.5 Mbps â Asymmetric Digital Subscriber Line Lite which offers maximum of 1.5 Mbit/s downstream and 512 kbit/s upstream and does not require the use of phone line splitters.ADSL2 12 Mbps â ADSL 2 extends the basic technology of ADSL, where the data rates extends to 12 Mbit/s downstream and 3.5 Mbit/s upstreamADSL2+ 24Mbps - ADSL2+ extends capability of ADSL by doubling the number of downstream bits. The data rates can be as high as 24 Mbit/s downstream and upstream 1.3 Mbit/s. But ADSL 2+M can handle 3.3 Mbit/s upstreamVDSL2 250 Mbps â Very high speed digital subscriber line 2 (VDSL) VDSL2 is the latest and advanced standard of DSL broadband wireline communication, which can handle 250 Mbit/s. VDSL2 will work fine when the telephone exchange is very near in the distance of (0.5)KM.PON â Passive optical network is a point to multi-point fiber network, which can handle 2.488 Gbit/s of downstream bandwidth, and 1.244 Gbit/s of upstream bandwidth.Mobile CommunicationGSM â Global System for Mobile Communications normally used in 2G communication which can handle voice codecs in the full rate of 13 kbit/s speed.GPRS â General packet radio service which offers around 32-40 kbit/s speed depending on the mobile phone.EDGE - Enhanced data rate for GSM evolution which can carry bandwidth up to 236.8 kbit/sWCDMA â Wideband code division multiple access which can carry bandwith up to 384 Kbit/sHSPA â High speed packet access is an combination of two mobile telephony protocols, High Speed Downlink Packet Access and High Speed Uplink Packet Access that extends and improves the performance of existing WCDMA protocols, which is commonly known as 3G.
1G: First Generation Cellular PhonesIn the 1970s, the First Generation, or 1G, mobile networks were introduced. Cell phone signals were based on analog system transmissions, and 1G devices were comparatively less heavy and expensive than prior devices. Some of the most popular standards deployed for 1G systems were Advanced Mobile Phone System (AMPS), Total Access Communication Systems (TACS) and Nordic Mobile Telephone (NMT). The global mobile phone market grew from 30 to 50 percent annually with the appearance of the 1G network, and the number of subscribers worldwide reached approximately 20 million by 1990.2G: GSM and GPRS NetworksIn the early 1990s, 2G phones deploying GSM (Global System for Mobile). GSM uses digital modulation to improve voice quality but the network offers limited data service. As demand drove uptake of cell phones, 2G carriers continued to improve transmission quality and coverage. The 2G carriers also began to offer additional services, such as paging, faxes, text messages and voicemail. The limited data services under 2G included WAP, HSCSD and MLS.An intermediary phase, 2.5G was introduced in the late 1990s. It uses the GPRS standard, which delivers packet-switched data capabilities to existing GSM networks. It allows users to send graphics-rich data as packets. The importance for packet-switching increased with the rise of the Internet and the Internet Protocol, or IP. The EDGE network is an example of 2.5G mobile technology.Recent 3G NetworksThe 3G revolution allowed mobile telephone customers to use audio, graphics and video applications. Over 3G it is possible to watch streaming video and engage in video telephony, although such activities are severely constrained by network bottlenecks and over-usage. 3G phone speeds deliver up to 2 Mpbs, but only under the best conditions and in stationary mode. Moving at a high speed can drop 3G bandwidth to a mere 145 Kbps.High-Speed 4G Mobile NetworksThe current generation of mobile telephony, 4G has been developed with the aim of providing transmission rates up to 20 Mbps while simultaneously accommodating Quality of Service (QoS) features. QoS will allow you and your telephone carrier to prioritize traffic according to the type of application using your bandwidth and adjust between your different telephones needs at a moment's notice.Only now are we beginning to see the potential of 4G applications. They are expected to include high-performance streaming of multimedia content. The deployment of 4G networks will also improve video conferencing functionality. It is also anticipated that 4G networks will deliver wider bandwidth to vehicles and devices moving at high speeds within the network area.
there is also an increasing number of broadband service providers via online cable or satellite connections in Mozambique. The more providers, the better for the consumers!
