2. WHAT IS 3G ?
• 3G is the third generation of wireless technologies.
• 3G is mostly used with mobile phones and
handsets.
3. HISTORY
• Introduced in 1990's by the ITU
• IMT-2000 (International Mobile Communications
2000)
• Japan was the first country to implement 3G
4. PREDECESSORS
• 1G provided only analog voice services .
• AMPS - Advanced Mobile Phone Service
• Digitization of control signals and voice signal
were developed during the second generation
which is 2G.
5. THE THIRD GENERATION (3G)
• Faster communications services which include:
• Voice
• Fax
• Internet with seamless global roaming

12. EFFECTS OF 3G ON SOCIETY
• Mobile Internet connectivity
• Mobile email
• Mobile Interview
• E-learning & m-learning
• Multimedia services, such as digital photos taken by and shared
via wireless handsets
• Wireless application downloading
• Video-on-demand and short-format Clipcast™ content
• Real-time multiplayer gaming
• Enhanced emergency and location-based services
• Low-latency push-to-talk and push-to-video message services
13. BENEFITS OF 3G
• Higher call volumes and support for multimedia data
applications, such as video and photography.
• Faster data transfer rates
• Free or cheap calls worldwide
• Capability to determine geographic position of mobiles
and report it
• Worthwhile for users that need connectivity on the move
14. DOES THIS PROVIDE A PICTURE AS IF 3G IS
ONLY FOR THE "ROAD WARRIORS" WHO ARE
ON THE MOVE ALWAYS ?
15. NO
•Solution for all Employees
•On-site maintenance engineers who need access to detailed
instruction manuals
•Mobile emergency services that a video need link with a
hospital or doctor for specialized advice
16. ISSUES HAMPERING ITS GROWTH
•
High spectrum licensing fees for the 3G services
•
Huge capital required to build infrastructure for 3G services.
•
Health impact because of electromagnetic waves.
•
Prices are very high for 3G mobile services.
•
Will 2G users switch to 3G services?
•
Takes time to catch up as the service is new.
17. VARIOUS SERVICES THAT 3G (W-CDMA)
COULD PROVIDE:
• 3G eases the machine to machine communication in the near
future
For Example: Refrigerator with in-built sensors, sensing the emptied
shelves and sending messages automatically to the PDA of the
user or the local store to refill it.
18. CONCLUSION
•
3G services will add invaluable dimension for the integral part of the modern
world
•
In the near future, Mobility will not be considered as an add-on: it will become a
fundamental aspect
•
Development of 3G networks will continue and pick up pace in the near future
