Extensibility e.g., remote areas with
Freedom to roam.
3. Mobile Wireless technology
First Generation Second Generation
Third Generation Fourth Generation
4. First Generation Wireless
Developed in 1980’s.
Analogue transmission technology.
Focus on voice.
Data services almost non-existent.
• Different frequencies and signaling.
• International roaming impossible.
5. Analysis of 1G
• 1st wireless • Low capacity,
• Focussed on
• No threats. • Its an
7. Second Generation Wireless
It was invented and developed in
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.
MMS & SMS
Search and directory.
9. 2.75 G Wireless
Data rates for GSM Evolution (EDGE).
Invented and developed by Cingular
Maximum speed 384 kb/s.
Works only on GSM networks.
10. 2G Analysis
• Digital. • Higher data
• More bandwidth
• No threats. • No
12. Third Generation Wireless
Introduced in 2004-05.
Perfection as like a real conversation.
Highly sophisticated form of
Video on demand
Location Based Services
13. 3.5 G Wireless
Known for HSDPA (High-Speed Downlink Packet
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
14. 3.75 G Wireless
The 3.75G refer to the High Speed Uplink Packet Access
The HSUPA mobile telecommunications technology is directly
related to HSDPA and the two are complimentary to one
HSUPA will enhance advanced person-to-person data
applications with higher and symmetric data rates, like
Real-time person-to-person gaming.
15. 3G Analysis
• Worldwide •Higher cost as
standard for compared with
•Since 2G mobile •Consumers
is in replacing
market, sqeezing handsets with
the market newer technology.
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
18. 4G Analysis
• Strong position of telecom
vendors expected in
Strength • Advantage for personalized
• Growing divergence
between telecom vendors &
Weakness • Comparatively higher cost
to use & deploy
19. 4G Analysis
• Worldwide economy recover
stimulates consumption and
Opportunities • Desirable higher data capacity
rates the growth opportunity is
very bright & hopeful.
• Since 3g mobile is still in the
market, it squeezes the market
competition in mobile industry.
20. Comparison between 1G,2G,3G & 4G
Generation Time Definition Characteristics Speed
