The document discusses the evolution of wireless technologies from 1G to 5G. It describes the key features and limitations of each generation including speed increases over time from 10 kbps for 1G to 1 GB for 4G. 5G is expected to offer speeds up to 10 Gbps. The need for 5G is driven by more users and the demand for faster data transmission for applications like streaming high definition content. However, 5G also faces challenges in terms of high costs, security concerns, and potential health effects that still need to be addressed.

4. Brief on Wireless Technologies
•Generations
•1G (1981)
•2G (1991)
•3G (2001)
•4G (2010)
•5G (2020)

5. 1G
1. Belongs to 1980
2. Analog Signal
3. Speed in 10 kbps.

6. Drawbacks of 1G
•Poor Voice Quality
•Poor Battery Life
•Large Phone Size
•No Security
•Limited Capacity

7. 2G
• Introduced in 1991 (Finland)
• Based on GSM
• Speed: 64 kbps
• Services: TEXT MSG, Picture MSG
and MMS
• Better Quality and Capacity.

8. Drawback of 2G
• Network Coverage Issue (Weak signal)
• Unable to handle complex data(Videos).

9. 3G
•Introduced in
2000.
•Speed – 144knps
to 2Mbps
•“Smartphone”
Tagline.
Features
-Faster
Communication
-Send Receive large
EMAIL
-High Speed Web.
-TV Streaming
Hardly takes 2 min

10. 4G
• High Speed Data Access
• High Quality Steaming
Videos
• Combination of Wifi.
• Speed- up to 1 GB
• “ANY THINGH ANY
WHERE”
Features Include:
MORE SECURITY
HIGH SPEED
HIGH CAPACITY
LOW COST PER BIT
Drawbacks:
• Battery uses is more.
• Hard to implement.
• Need Complicated
hardware.
• Expensive

11. What is the need for 5G?
• 3.4 Billion of Broadband Users (80% Mobile Broadband Subs) by 2014.
• Majority served by LTE Network(Long Term Evolution) which provide
500Mbps - 1Gbps of bandwidth.
• No such ground breaking Apps available in real world to utilize by a common
man.

12. MAJOR DIFFERENCE:

13. Comparison on Data rate

14. 5G Architecture

15. 5G Benefits(4G + WWWW)
• High Capacity, High
Speed.
• 5G technology
providing large
broadcasting of data
in Gbps.
• High Definition
Newspaper, watch
Online TV with less
buffer time.
• Faster Data
Transmission relate
to 4G
• Large Phone
Memory
• Dialing Speed

16. Risk
&
Challenges:
• Globalization leads
security concern.(IP)
• Cost on Nano-Core is
very High.
• New Technology should
not harm Human
Health.

17. Conclusion
While the future is becoming more difficult to predict with each
passing year we conclude that nanotechnology, Cloud computing,
All IP are the next great technology wave. 5G`s Nano-Core
innovations enable futuristic business approaches and this will
change the world.
