1. 1G technology, developed in the 1980s, was based on analog systems with speeds up to 2.4 kbps. It allowed basic voice calls but had poor voice quality, battery life, and size. 2. 2G technology, developed in the late 1980s-1990s, was based on digital systems with speeds up to 64 kbps. It provided clearer digital voice and SMS but required strong signals and could not handle more complex data like videos. 3. 3G technology, developed from the late 1990s to present, had transmission speeds from 125 kbps to 2 Mbps and allowed services like video calls, email, banking, and games but was expensive to build and required high bandwidth

3. EVOLUTIONS OF
TECHNOLOGY

4. 1G TECHNOLOGY
Developed in 1980s & completed in
early 1990s.
Based on analog system.
Speed up to 2.4 kbps.
 AMPS (Advance Mobile Phone
System) was launched by the US & it
was the 1G mobile system.
 Allows user to make voice calls in 1

5. DRAWBACKS IN 1G TECHNOLOGY
Poor Voice Quality
Poor Battery Life
Large Phone Size
No Security
Limited Capacity
Poor Handoff Reliability

6. 2G TECHNOLOGY
 Developed in late 1980s & completed in
late 1990s
 Based on digital system
 Speed up to 64 kbps
 Services such are digital voice & SMS
with more clarity
 2G are the handsets we are using today,
with 2.5G having more capabilities

7. DRAWBACKS IN 2G TECHNOLOGY
 2G requires strong digital signals to help mobile
phones work. If there is no network coverage in
any specific area , digital signals would weak.
 These systems are unable to handle complex data
such as Videos.

8. 3G TECHNOLOGY
 Developed between late 1990s & early
2000s until present day
 Transmission speed from 125 kbps to 2
Mbps
 Superior voice quality
 Good clarity in video conference
 E-mail, information surfing, on-line
shopping/ banking, games

9. DRAWBACKS IN3GTECHNOLOGY
 Expensive fees for 3G Licenses
Services
 It was challenge to build the
infrastructure for 3G
 High Bandwidth Requirement
 Expensive 3G Phones.
 Large Cell Phones

10. 4G TECHNOLOGY
Developed in 2010
 Faster & more reliable
 Speed up to 100 Mbps
 High performance

11. DRAWBACKSIN4G TECHNOLOGY
 Battery uses is more
 Hard to implement
 Need complicated hardware
 Expensive equipment required to implement
next generation network.

12. WHAT DO YOU EXPECT FROM
