  2. Presentation Outline •  Introduction •  National Broadband Initiatives •  Vision of MIMOS Mi-WiWi •  Wireless Communications R&D Activities •  Scope of Collaboration - MIMOS-NICT Wireless Communications •  Conclusion

  3. In 2005, Malaysia targets 75% Broadband Household Penetration by 2015

  4. USD 15,000 RM 48,000 Per capita NKEA will boost our Gross National Income (GNI) by 2020 A National Key Economic Activities (NKEA) is a driver of economic activity that has the potential to directly and materially contribute a quantifiable amount of economic growth to the Malaysian economy USD 6,700 RM 23,770 Per capita [Source: PEMANDU http://www.pemandu.gov.my/]

Local content hub to vitalise creative sector, reduce dependence on international connectivity, and export content ! Integrated approach to provide access, devices, and platforms/content/ applications to benefit the learning " Rakyat " Establishing broadband as an essential service to Malaysians on par with other utilities, e.g. water and electricity " 1MY Payment ! E-Healthcare ! Extend Reach ! 1b ! 2b ! 3b ! Common standards, platforms and security protocols to cashless payment to masses in Malaysia " Networked healthcare providers to each other and to their patients to improve productivity and information management " Acceleration and expansion of broadband coverage in non-urban areas (e.g. to Zone 2 and " Zone 3) " Connecting 1MY ! E-Government ! Smart Network ! Next-generation services to provide ubiquitous connectivity and compelling services for the Rakyat at home, in the workplace, " and ‘on-the- " move’ " 1c ! 2c ! 3c ! Increasing the accessibility, speed, and transparency of government services through communications technology " Differentiated pricing to provide higher quality and more affordable service " Regional Network ! 3d ! Capacity increase of Malaysia’s submarine cable network to lower international IP connectivity costs " [Source: PEMANDU http://www.pemandu.gov.my/]
