3. A Couple of Decades Ago?
 1G-First Generation (1980s to 1990’s)
Speech
2.4 kbps speed
Poor Voice quality
Analog Signal
 2G-Second Generation
Digital Signals
64kbps
GSM
SMS , MMS

4. 3-G
3G-Third Generation
Wireless Internet
Video Calling
 Mobile TV
 Drawbacks
High Bandwidth Requirements
High spectrum licensing fees
Huge capital

5. Future Demands..!
4G
3G
2G
1G
High transfer rate
 Internet access any where
 Ability to move around with the
same IP address
 Utilization of Smart antennas
 High resolution Mobile TV

6. What’s new in 4G ?
o IP (InternetProtocol) based
mobilesystems.
o Entirely packet-switched
networks.
o Digitalin nature
o Wider Bandwidths 100Mhz

7. How 4G is better than 3G

8. Speed Comparison
• Speedy:
• 4G is quicker than 3G which means less
buffering, better audio quality, improved
gaming experience and streaming services.

9. The 4G network
• 4G offers is very good for advanced mobile
services such as video and movie streaming. This
offers much higher speed than 3G
• Unlike 3G, 4G has far expanded coverage and
hence, offers more or less constant connectivity.

10. Latency Time
• Latency is a measure of the time it takes for
data to travel from a PC/Mobile to the
internet and back. On 4G that time is around
half that experienced on current 3G.
• video conferencing
• internet gaming
with less buffering and fewer interruptions.

11. Benefits of 3G and 4G:
• Much faster web browsing.
• Video streaming.
• Internet calls and voice over IP (VOIP)
• Music
• Photo sharing
• Email and attachments
• Downloading apps

12. How 4G is Better than 3G
Technology 3G 4G
Data Transfer Rate 3.1MB /sec 100MB/sec
Internet services Broadband Ultra Broadband
Mobile -TV Resolution Low High
Bandwidth 5 - 20 MHz 100+ MHz
Frequency 1.6 - 2 GHZ 2 - 8 GHz
Network Architecture Wide Area Network Hybrid Network
Signal Quality Good Best
Communication Type Circuit Switching Packet Switching

13. Technology 3G 4G
Data Transfer Rate 3.1 MB/sec 100 MB/sec
Internet Services Broadband Ultra Broadband
Mobile - TV Resolution Low High
Bandwidth 5-20 MHz 100MHz
Frequency 1.6-2 GHz 2-8 GHz
Download and upload 5.8 Mbps 14 Mbps
Why 4G is Better than 3G

14.  Better Usage of Multimedia Applications.
 Video Conferencing.
 Graphical Maps of streets, buildings, and
physical characteristics of a large metropolis
on a vehicle.
Applications of 4G

15. 4-G in PAKISTAN
 Government has already Auctioned the 3G and 4G Licenses
 Pakistan is among the latecomers in 3G but not very late in 4G
 3 Telecom Companies bided for 3G Technology. i-e. Ufone, Mobilink,
Telenor.
 Zong bided highest amount for only 4G Spectrum.
 3G auction was postponed by government for more than 1 year due to
some personal political wishes but at last Supreme Court of Pakistan
ordered PTA for the auction of 3G and 4G spectrum and hence it
happened.

16. Advantages of 3G
Bandwidth, security and reliability are more.
Provides interoperability among service providers.
Availability of fixed and variable rates.
Support to devices with backward compatibility
with existing networks.
Always online devices 3G uses IP connectivity
which is packet based
Rich multi media services are available.

17. Disadvantages 3G
The cost of cellular infrastructure , upgrading
base stations is very high.
Needs different handsets.
Roaming and data/voice work together has
not yet been implemented.
Power consumption is high.
Requires closer base stations and are
expensive.
Spectrum-license costs, network deployment
costs and handset subsidies subscribers are

18. Advantages of 4G
 Affordable communication services.
 High speed high capacity and low cost per bit.
 Support for interactive multimedia, voice ,
streaming video, Internet and other broadband
services.
 Global access, Service portability and scalable
mobile services and variety of quality of services
provided.
 Better spectral efficiency.

19. Disadvantages 4G
 Battery usage is more.
 Hard to implement.
 Need complicated hardware.
 The equipment required to implement a next
generation network is still very expensive.
 4G Device Needed to avail services of 4G Technology.

20. Challenges
 Competition with the next forth coming 5G.
 5G technology is providing large broadcasting of
data in Gigabit which supports almost 65,000
connections.
 5G technology would provide better use of available
bandwidth.

21. Conclusion
Mobile…. Multimedia …..
Anytime….. Anywhere…..
Global mobility…..
Integrated wireless…..
Personalized services…..
That’s……..
