Africa.

Introduction.

• FACTS
• Africa is the most unwired continent in the
  world, most of its internal communication(voice,da
  ta,and video) has to be resolved internationally.
• It has been estimated that for data alone this
  routing of traffic costs the continent US660
  million a year.

3
Facts

• The transmission capacity required to carry
  Africas international voice and data traffic
  increased by 137 to 12.09Gbps in 2005, and will
  increase by 81 to 21.9Gbps in the year 2008.
• The bandwidth projection for Sub-Saharan Africa
  alone would be around 24 overall growth in the
  year 2008

4
Fact

• The demand projections suggest the need for a
  robust passive infrastructure build-out in and
  around Africa to address this large unmet demand
  for information and communication services.

5
Facts

• Africa targets tele-density of 10 by 2010
• This implies over 10b investment per annum over
  the next ten years.
• 33 mobiles operator in 1999, now 120 telcos.
• Revenues from data traffice increases from
  between 20 to 100 for the mobile telcos.

6
AFRICA INTERNET USAGE

• 915,210,928 Population 2006 estimate for Africa
• 32,765,700 users in Africa as of Sept. 18th,
  2006, a 3.6 penetration rate
• 1,053,485,203 users in the rest of the world as
  of Sept. 18th, 2006, a 18.9 penetration rate

7
Internet

• The maturation of the Global IT market has
  resulted in revenue declining in the more
  developed ICT markets. In order to achieve growth
  targets, technology vendors are looking to
  emerging markets, among them Africa.
• The exponential growth experienced in the IT
  markets in Africa has heralded an awakening of
  the wealth of ICT opportunities that exist across
  the continent.

FUTURE EXPLOITATION

• Services (voice, data, TV, etc.) will no longer
  depend on specific facilities (copper, radio,
  coax, fiber, satellite)
• All services will be available over all
  communications facilities
• Communications companies will compete in an open
  market to offer the cheapest, highest-quality
  services

AFRICA TELECOM STATISTICS

• African will be one of the most important Telecom
  (Voice Data) markets in the world in the near
  future
• This is because,
• As of 2006 Africa accounts for only 4 percent of
  the worlds Teledensity(ratio of people phones)

A REGION OF GROWTH

• Wireless services look set to hold the key to
  Africa's ICT future
• Mobile use in Africa has skyrocketed and the
  continent is a world leader in mobile growth
  terms
• New wireless technologies such as WiFi and WiMax
  are also likely to shape Africas ICT future
  extending the reach of Telecommunications further
  into previously untapped areas

AFRICA GROWTH RATES AGAINST OTHER REGIONS

• The overall growth in the Africa continent with
  other regions is illustrated below.
• The figure shows the opportunity present in
  Africa currently by presenting the Compound
  Annual Growth Rates(CAGR) from 2004 to 2008 for
  Hardware, Software, Services, Telecommunications
  operators and IT in total.

Hope for the Telecom Industries

• Q Is there any hope for the African telecom in
  the All-IP Future?
• A Yes
• Diversify into IP networks, the sooner the better
• Telecom as connectivity cloud, selling various
  avenues of access (copper, GSM, 3G, WiFi, cable,
  whatever)
• Offer integrated services (voice, text, audio,
  video), over a satellite connection
• Retain customers and expand traffic!

33
Hope for Telecom - contd

• Africa will provide the perfect opportunity to
  explore the regions rapidly expanding ICT
  sector, as well as other opportunities for growth
  which the region offers.
• African ICT indigenous players are increasingly
  making their mark, developing solutions which are
  designed to the specific needs of the African
  region.
