 The 3G network is the third generation of mobile networking
and telecommunications. It features a wider range of services
and advances network capacity over the previous 2G network.
The 3G network also increases the rate of information transfer.
 Wireless networking technology that uses radio waves to
provide wireless high-speed Internet and network connections.
The Wi-Fi Alliance, the organization that owns the Wi-Fi
(registered trademark) term specifically defines Wi-Fi as any
"wireless local area network”

5.
 Japan and South Korea were the first countries to successfully
launch this network. The Japanese company FOMA launched
in May 2001 and South Korea's SK Telecom launched in
January 2002.
 3G technologies allow mobile operators to offer more service
options to their users, including mobile broadband.
 3G is made possible by two complementary technologies -
HSDPA and HSUPA

6.
 Wi-Fi stands for “Wireless Fidelity”.
 It is the popular name for wireless Ethernet 802.11b
standards for WLANS.
 Wi-Fi allows collection of PC’s, peripherals ( printers,
access servers etc. ) to share resources.
 It mostly used in universities ,companies etc.,

7.
 Both are wireless technology.
 Both facilitates mobility.

Both are access technologies. vs
 Both offers broadband data services.
W
i-Fi

8.
 Current business models/deployment are different
 Spectrum policy and management
 Status of technology development different
◦ Deployment status
◦ Embedded support for services
◦ Standardization
◦ Service/business model

9.
 Wi-Fi is good for competition
 Wi-Fi and 3G can complement each other for a mobile Provide
 Spectrum policy is key
 Success of Wi-Fi is potentially good for multimedia content

10.
This presentation offers a qualitative comparison of
two wireless technologies that could be viewed
simultaneously as substitute and/or complementary
paths for evolving to broadband wireless Traditional
radios are based on dedicated hardware.
The goal of the analysis is to explore two divergent
world views for the future of wireless access and to
speculate on the likely success and possible
interactions between the two technologies in the
future.
