 Communication Trends in Developing Countries like
                     Tanzania

•Public switched Telecommunication Networks
•Global Systems for Mobile Communication
•Systems have been designed for high capacity
•in low density and non urban areas results to higher
cost of communication services

      Technologies in Developed Countries

• Global Systems for Mobile Communications
• General Packet Radio Services
• Enhanced Data rates for Groupe Special
  Mobile (GSM) Evolution (EDGE)
• WCDMA
• IS-95,
• CDMA20001X
• PLC
• WiFi
• And so on.

   Can technologies in developed countries be
        transferred to developing World?

•Most are saying No
•Some are saying may be

why?
•Investments done in GSM in some of the
countries
•Initial investment of technologies like
    3G technologies
•Regulation Issues


                                                7
          Key issues and Proposed Solutions

•Apart from Regulatory Issues

•Integrating technologies depending on serviced areas

•Current trend “End users are looking more data”

•Data consumed more bandwidth hence more money.

•Powerline Networking infrastructure can integrate
different cities, municipality in different African Countries.
For example when we are talking a teledensity of 1.42 in
Tanzania Electricity is 10%.

                                                           8
     Current Trends in Powerline Communication

•Open PLC European Research Alliance (OPERA) Project
 target (200Mbps in the second phase): Strategic objective of OPERA
project is to offer low cost broadband access services to all European
citizens using PLC. First phase (2004-2005). Standard and
compatibility.
•PLC Commercial Deployment of Iberdrola: PLC600 offers up to
600kbps upstream and up to 600kbps downstream with tariff
competing with ADSL tariff for the 256/128kbps services.
•PLC Commercial Deployment of ENDESA (20Mbps VoPLC) have
covered 20,000 homes in Spain, Internet Access over 2Mbps. PLC cost
competitive with ADSL.
•PLC technology of DS2. 1st generation 45Mbps, now DSS900X is a
200Mbps Digital Modem ICs.
•High Speed Powerline Communication Network by Korea
Electrotechnology Research Institute (KERI) is (2Mbps-45Mbps)
                                                                 9
Can already developed solutions in powerline suite
      the environment of African Countries?
•No it needs modifications in the PLC of developing countries to be
able to implement PLC solutions.

•The study of Network behaviour, Measurements of network is needed
to be able to implement a PLC solution.

PLC is affected by
• Number of Customers Connected per feeder (Interconnection)
• Topology of PLC which is different from developed countries.
•Distances
•Overhead and separation of cables makes channel characterization
  to be different it needs study before implementation of actual
  solution.

  Cont. The role of the Faculty of ECSE, UDSM to
    develop and deploy PLC solution in Tanzania.
•Our Aim is to have a Pilot project of Powerline Communication
    in Tanzania with the AIM of “ICT Accessibility for all with
    Electricity”.
•We have identified the areas whereby most of Cities like
   Mwanza and Municipality such as Iringa, Mbeya and Others
where PLC solution can be Implemented
• PLC can be deployed and Many users be Connected to world
  Internet and making calls
•We have Communicated with Industries such as Korea
Electrotechnology Research Institute (KERI) to see the
possibility of Taking our results and develop PLC for Tanzania.
•We are looking other Companies and donors to extend the
PLC project and make the Powerline communication real in
Tanzania.                                                       15

• PLC Network can enhance the break
  through the digital divide and accessibility
  of ICT in African countries.
• The Project is “ICT Accessibility for all with
  Electricity in Tanzania”.
