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

Communications •  Conclusion

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

NKEA will boost our Gross National Income (GNI) by 2020

USD 15,000 RM 48,000

Per capita

USD 6,700 RM 23,770 Per capita

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

Value gap

•  Poor Value realization due to Insu!cient value creating content

•  Barrier to entry due to literacy level and language

• Complexity of Computers

• Connectivity • Devices

Scenario$

Experimental Results

•  Conventional fixed frequency transmission at 2.4GHz frequency in the presence of other user (using the same frequency)

•  Video transmission was interrupted due to co-channel interference.

•  Dynamic frequency selection algorithm at 2.4GHz frequency in the presence of other user (using the same frequency)

•  No interruption in video transmission as the cognitive WiWi is aware of the interference and select new frequency to transmit
