4. Introduction What is the Generation of cellular network technology ??

5. 1 st Generation (1G) The first commercially automated cellular network (the 1G) was launched in Japan by NTT (Nippon Telegraph and Telephone) in 1979, initially in the metropolitan area of Tokyo. First generation used Total Access Communication System (TACS).

6. Drawbacks of 1G Poor voice quality Poor battery life Large phone size No security Frequent call drops Can’t send text message

7. 2 nd Generation (2G) 2G is short for second-generation wireless telephone  technology. Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja in 1991.

8. Benefits of 2G Technology Phone conversations were digitally encrypted. Text message service. Roaming facility. Drawbacks of 2G Technology Roaming facility is semi-global Voice quality is not so good

9. 2.5G wireless An interim stage that is taken between 2G and 3G that is 2.5G. Features includes Phone calls/ Fax Voice mail Send/ Receive e-mail message web browsing Camera phones Speed: 64-144 kb/sec

10. 3 rd Generation (3G) To meet the growing demand in network capacity, rates required for high speed data transfer and multimedia applications, 3G standard started evolving. 3G technologies enable network operators to offer users a wider range of more advanced services. Data are sent through the technology called packet switching / circuit switching.

11. Features includes Phone calls/ Fax Global roaming Send/ receive large email messages High speed web Navigation/ maps Video conferencing TV streaming Speed : 200 kb/sec- 2 mb/ sec

12. Advantages of 3G More bandwidth, security & reliability. Inter- portability between service providers. High data rates. Rich multimedia services. Always online devices.

13. Disadvantages of 3G Expensive input fees for the 3G service licenses. Numerous differences in the licensing terms. It is a challenge to build the necessary. Infrastructure for 3G. Expense of 3G phones.
