Slide 1: 

ONE TH ING IS SURE FUTURE WILL BE UNLIKE ANYTHING WE KNOW.

Slide 2: 

BY FAIZA TABASSUM BAHRIA UNIVERSITY ISLAMABAD 3G Wireless Telephone Technology (World in your fist)

OVERVIEW: 

This first generation (1G) analog system for mobile communications saw two key improvements during the 1970s: the invention of the microprocessor and the digitization of the control link between the mobil phone and the cell site. Second generation (2G) digital cellular systems were first developed at the end of the 1980s. These systems digitized not only the control link but also the voice signal. The new system provided better quality and higher capacity at lower cost to consumers. OVERVIEW

Slide 4: 

Third generation (3G) systems promise faster communications services, including voice, fax and Internet, anytime and anywhere with seamless global roaming. ITU’s IMT-2000 global standard for 3G has opened the way to enabling innovative applications and services (e.g. multimedia entertainment, infotainment and location- based services, among others). The first 3G network was deployed in Japan in 2001.  2.5G networks, such as GPRS (Global Packet Radio Service) are already available in some parts of Europe. Work has already begun on the development of fourth generation (4G) technologies in Japan. OVERVIEW

Slide 5: 

3G network is one of the leading technologies in today’s wireless technology. This service is available with any wireless phones. Verizon is the first one to use this. It was first implemented on CDMA phones .now this service is coming soon with GSM. 3G is nothing but fast stream and high bandwidth . 3G

Feature Of 3G: 

Feature Of 3G High-speed data transmissions Symmetrical and asymmetrical data transmission support Improved voice quality Greater capacity Multiple simultaneous services Global roaming across networks Improved security Service flexibility 3G promises increased bandwidth. up to 384 Kbps at stable. 128 Kbps in a car or moving. 2 Mbps in fixed applications. 3G work over wireless air interfaces such as GSM, TDMA, and CDMA.

Technical Specifications: 

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). Technical Specifications

3G Protocol: 

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)

3G Applications : 

3G Applications Wireless Internet Audio on demand Electronic postcards Video conferencing Secure mobile commerce transactions Traffic and traveling information - location specific.

Slide 14: 

A great deal of potential exists for new applications in the future as 3G packet based networks will allow users to be on line all the time. The capabilities of wireless networks in terms of bandwidth must still, however, be improved upon .
