2. INTRODUCTION
 WIRELESS COMMUNICATION-
Transfer of information without ‘Wires’
 MOBILE WIRELESS INDUSTRY-
started technology creation in early 1970’s.
 Advantages –
 Constant connection
 Access to up-to-date information
 No cables
 Extensibility e.g., remote areas with
satellite
 Freedom to roam.

4. First Generation Wireless
 Developed in 1980’s.
 Analogue transmission technology.
 Focus on voice.
 Data services almost non-existent.
 Incompatible standards:-
• Different frequencies and signaling.
• International roaming impossible.

7. Second Generation Wireless
It was invented and developed in
1990-91.
Digital transmission technology.
Increased quality of service
Possibility of wireless data services
Most successful 2G system
 863 million users in 197 countries.

8. 2.5 G Wireless
 General Packet Radio Service (GPRS)
 Data rates- 56 kb/s to 115 kb/s.
 Services-
WAP
MMS & SMS
Search and directory.

9. 2.75 G Wireless
Data rates for GSM Evolution (EDGE).
Invented and developed by Cingular
(AT&T).
Maximum speed 384 kb/s.
Works only on GSM networks.

12. Third Generation Wireless
 Introduced in 2004-05.
 Increased clarity.
 Perfection as like a real conversation.
 Highly sophisticated form of
communication.
 Applications are:
 Mobile TV
 Video on demand
 Video Conferencing
 Location Based Services

13. 3.5 G Wireless
 Known for HSDPA (High-Speed Downlink Packet
Access).
 It provides a smooth evolutionary path for 3G
networks allowing for higher data transfer speeds.
 Data transmission up to 8-10 Mbit/s (and 20 Mbit/s for
some systems).

14. 3.75 G Wireless
 The 3.75G refer to the High Speed Uplink Packet Access
(HSUPA) technology.
 The HSUPA mobile telecommunications technology is directly
related to HSDPA and the two are complimentary to one
another.
 HSUPA will enhance advanced person-to-person data
applications with higher and symmetric data rates, like
 Mobile e-mail.
 Real-time person-to-person gaming.
 Speed 1.4Mbps-5.8Mbps.

17. Fourth Generation Wireless
Successor to 3G and 2G.
A collection of technologies creating fully
packet-switched networks optimized for data.
 Provide speeds of 100 Mbps to 1 Gbps.
 Provides wireless alternative for broadband
access to residential and business customers.
In addition, 4G will provide the first
opportunity for broadband access in remote
locations.

24. Conclusion
 Attempts have been made to reduce a
number of technologies to a single global
standard.
 Upcoming 4G systems offer this promise of a
standard.
 So 4G will be the best as compared with its
predecessors.
