3G

  1. 1. What is 3G? • 3G is the third generation technology offering broadband mobile communications with voice, video, graphics, audio and other information. • It supersedes 2G and precedes 4G. • 2.5G was a temporary bridge between 2G & 3G. • Required Features: – faster data-transmission speeds. – greater network capacity. – more advanced network services.
  2. 2.  3G facilitates several new applications that have not previously been readily available over mobile networks due to the limitations in data transmission speeds.  These applications range from Web Browsing to file transfer to Home Automation.  Because of the bandwidth increase, these applications will be even more easily available with 3G than they were previously with interim technologies.
  3. 3. Feature Of 3G • • • • • 3G promises increased bandwidth. up to 384 Kbps at stable. 128 Kbps in a car or moving. 2 Mbps in fixed applications. 3G will work over wireless air interfaces such as GSM, TDMA, and CDMA. • The new EDGE air interface has been developed specifically to meet the bandwidth needs of 3G.
  4. 4. How does 3G works? • 3G technology is intended for the true multimedia cell phone(Smartphone). • Features increased bandwidth and transfer rates to accommodate Web-based applications and phone-based audio and video files. • 3G networks have potential transfer speeds of up to 3 Mbps (3min mp3 take 15 sec to download). • Comparison to the fastest 2G phones can achieve up to 144Kbps (3min mp3 take 8 min to download).
  5. 5. Services By 3G • • • • • video conferencing receiving streaming video from the Web IPTV sending and receiving faxes instantly downloading e-mail messages with attachments.
  6. 6. 3G Protocol • Protocols in 3G transmit data in terms of megabytes per second rather than kilobytes(some as fast as 10 Mbps). • Universal Mobile Telecommunication Service (UMTS) • Wideband Code-Division Multiple Access (WCDMA) • High-Speed Downlink Packet Access (HSDPA) • Evolution Data Maximized (EVDO)
  7. 7. 3G Development • December 2005, 100 3G networks were operating in 40 countries. • In Europe, 3G services were introduced starting in March 2003 in the UK and Italy. • By June 2007 the 200 millionth 3G subscriber had been connected. • The first commercial launch of 3G was by NTT DOCOMO in Japan on october 2001.
  8. 8. Advantage & Disadvantage of 3G • Advantage: – International Telecommunication Union . – International Mobile Telecommunications program. • Disadvantage: – 3G networks do not use the same radio frequencies as 2G. – Expensive.
