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”

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

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.,

Both are wireless technology.

Both facilitates mobility.

Both are access technologies. vs

Both offers broadband data services.

Wi-Fi

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

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

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.
