Advantages in Multipath

 OFDMA carries advantages in “Multipath”
 CDMA uses the whole spectrum, wasting system resource to combat
frequency selective fading.
 CDMA also creates worse interference problem
 OFDMA only select subcarriers with less channel degradation, prevent
wasting system resource (power or throughput ) => achieving higher system
capacity.

 Rural: 8.8%
 Urban: 65%
 Broadband: 0.4%
 Internet: 4%
 500 Million phone connections by

 PC Penetration: 2%
The Opportunity in India
 Web was “invented” by Tim Berners-Lee (amongst others), a physicist
working at CERN
 His vision of the Web was much more ambitious than the reality of the
existing (syntactic) Web:
 This vision of the Web has become known as the Semantic Web
“… a set of connected applications … forming
a consistent logical web of data …”
“… an extension of the current web in which
information is given well-defined meaning,
better enabling computers and people to work in
cooperation …”

Market & Time Competition
Marketing Hype
Disappointment
Rebuild Business Model
Steady Growth
 Market takes time!
 Markets takes time to mature;
most new services will follow the
letter “N” curve as below
 Fixed WiMAX technology is far
from mass adoption, mobile
WiMAX would take even longer
 WiMAX has risks too!
 Mobile WiMAX market is squeezed by both
3G, Flash OFDM, and WiFi.
 802.11e, 11r, and 11n are enhancing QoS,
handover, and throughput.
 HSDPA (of 3G) shorten the gap with WiMAX
in throughput.
 Flash OFDM (by Flarion) has demonstrated
end-to-end solution.

WiMAX vs. McWiLL in China
Multicarrier Wireless Internet Local Loop (McWill).
•China is testing a potential rival to WiMax, based on
SCDMA (still used in China in the 400-MHz band)
•The technology is known asMulticarrier Wireless Internet
Local Loop (McWill).
•It has been in field trials in a few Chinese cities, including
Guangzhou and Qingdao, where it has been used for video,
voice and data
