Evolution of wireless generations

  1. 1. Evolution of Wireless Generations
  2. 2.  In last few decades there is a great progress in wireless networks , namely from 0G to 4G.  1G  2G  3G  4G
  3. 3. 1G  1st Generation of wireless communication.  Was launched in Japan in 1979-1980.  Involve the technology AMPS (Advanced Mobile Phone System)  Data transfer rate is 2.4 Kbps
  4. 4.  1G uses analog signals , means the signals are not converted in digital one.  Called analog telecommunication standards.
  5. 5. Features  Allows the voice calls in one country.
  6. 6. Drawbacks  Poor voice quality  Poor battery life  Large phone size  No security  Limited capacity  Low data rate(As 1G uses analog signals so these signals can not cover up long distance so we have move forward.)
  7. 7. Problem  As analog signals cant cover long distance so that is the advantage of analog signal. Solution  Instead of sending analog signals they should be converted into digital signals
  8. 8. 2G  Uses digital technology.  Uses digital signals.  Introduced in Finland 1991-2000.  Data transfer rate is 64 kbps.
  9. 9. Features  Allows text messages , picture messages and MMS
  10. 10. Technology  GSM is the technology of 2G.  At start GSM stands for Groupe Special Module. Later on it changes to Global System for mobile communications.
  11. 11. Problem  Require strong digital signals for data transmission , in case of no network coverage , signals become week.  Unable to handle videos.
  12. 12. 2.5G  Follows the packet switching methodology.  From  Involv-2010  the technology named GPRS.  GPRS stands for General Packet Radio Service.  GPRS support the transmission of data in form of packets . And these packets are transmit through air (Radio).  GPRS refers to data rate of about 64-144 kbps.
  13. 13. Features  Phone calls  Send/receive email messages  Web browsing  Camera phones  Take 6-9 minutes to download a 3 min mp3 song.
  14. 14. Problem  Data rate is less
  15. 15. 3G  Introduced in 2000.  Data transfer rate is 144kbps – 2Mbps
  16. 16. Features  Faster communication  Send / receive large email messages  High speed web  High security  Video conferencing  3D gaming  TV streaming  11 – 90 sec to download a 3 minutes mp3 song.
  17. 17. 4G LTE  The target was set to  100 mbps – 1 Gbps  Introduced in 2009. After a long time research and working this target is achieved. That’s why its is called Long Term Evolution.
