Analysis of 1G, 2G, 3G & 4G

  1. Analysis & “ Add your company slogan ” Comparison of1G, 2G, 3G and 4GPRESENTED BY- LOGO Prateek Aloni
  2. INTRODUCTION WIRELESS COMMUNICATION- Transfer of information without ‘Wires’ MOBILE WIRELESS INDUSTRY- started technology creation in early 1970’s. Advantages –  Constant connection  Access to up-to-date information  No cables  Extensibility e.g., remote areas with satellite  Freedom to roam.
  3. Mobile Wireless technologyFirst Generation Second Generation Wireless Wireless (1G) (2G) GenerationsThird Generation Fourth Generation Wireless Wireless (3G) (4G)
  4. First Generation Wireless Developed in 1980’s. Analogue transmission technology. Focus on voice. Data services almost non-existent. Incompatible standards:- • Different frequencies and signaling. • International roaming impossible.
  5. Analysis of 1G• 1st wireless • Low capacity, cellphone unreliable introduced. handoff.• Focussed on voice. S W T O• No threats. • Its an outdated technology.
  6. Second Generation WirelessIt was invented and developed in1990-91.Digital transmission technology.Increased quality of servicePossibility of wireless data servicesMost successful 2G system  863 million users in 197 countries.
  7. 2.5 G Wireless General Packet Radio Service (GPRS) Data rates- 56 kb/s to 115 kb/s. Services- WAP MMS & SMS Search and directory.
  8. 2.75 G WirelessData rates for GSM Evolution (EDGE).Invented and developed by Cingular (AT&T).Maximum speed 384 kb/s.Works only on GSM networks.
  9. 2G Analysis• Digital. • Higher data• More bandwidth flexible. requirement. S W T O• No threats. • No opportunities
  10. Third Generation Wireless Introduced in 2004-05. Increased clarity. Perfection as like a real conversation. Highly sophisticated form of communication. Applications are:  Mobile TV  Video on demand  Video Conferencing  Location Based Services
  11. 3.5 G Wireless Known for HSDPA (High-Speed Downlink Packet Access). 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 some systems).
  12. 3.75 G Wireless The 3.75G refer to the High Speed Uplink Packet Access (HSUPA) technology. The HSUPA mobile telecommunications technology is directly related to HSDPA and the two are complimentary to one another. HSUPA will enhance advanced person-to-person data applications with higher and symmetric data rates, like  Mobile e-mail.  Real-time person-to-person gaming.  Speed 1.4Mbps-5.8Mbps.
  13. 3G Analysis• Worldwide •Higher cost as standard for compared with accessing their global predecessors. telecommunicat ions. S W T O•Since 2G mobile •Consumers is in replacing market, sqeezing handsets with the market newer technology. competition.
  14. 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 locations.
  15. 4G Analysis • Strong position of telecom vendors expected in market.Strength • Advantage for personalized multimedia communication tools. • Growing divergence between telecom vendors & operators.Weakness • Comparatively higher cost to use & deploy infrastructure.
  16. 4G Analysis • Worldwide economy recover stimulates consumption and consumer confidence.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. Threats
  17. Comparison between 1G,2G,3G & 4GGeneration Time Definition Characteristics Speed PeriodI (1G) 1980-1990 Analog Voice only 14.4 Kbps (peak)II (2G) 1990-2006 Digital narrow band Data along voice, 56Kbps to 115 circuit data/packet MMS, web kbps data browsing.III (3G) 2006-2011 Digital broadband Universal access, 5.8 Mbps to 14.4 packet data. portability, Video Mbps callingIV (4G) Now Digital broadband HD streaming, 100 Mbps to 1 (Upcoming) packet very high portability increased Gbps throughput to Worldwide roaming.
  18. Mobile Broadband Landscape Cellular Wireless Law of Speed vs. Decade 5G Mobile device 4G ? for everythingGbps 3GMbps 2Gkbps 1Gbps 30 Years 1980 1990 2000 2010 2020 Tim e
  19. Conclusion Attempts have been made to reduce a number of technologies to a single global standard. Upcoming 4G systems offer this promise of a standard. So 4G will be the best as compared with its predecessors.
