Mobile Communication Generation
- 1. MOBILE GENERATIONS Yansi Keim || 011020703111 || I.T. VIII Semester 1
- 3. 0TH GENERATION Pre-cell phone mobile telephony technology, such as radio telephones that some had in cars before the arrival of cell phones. Communication was possible through voice only. These mobile telephones were usually mounted in cars or trucks. Copyright @ CBPGECJ Technologies PTT(Push to Talk) MTS (Mobile Telephone System) IMTS (Improved MTS) 3

- 5. First Generation (1G) History This generation network’s were developed during1980’s in US. It got introduced in the place Israil in 1986. And the next place is Australia in 1987. Use This 1G network’s are based on analog radio signals. Example:- (AMPS): AMPS mean’s Analog Modulation Physical System. Disadvantage Main disadvantage of 1G technology is when the subscriber area enters other coverage area they have to register with current coverage area .i.e. By calling to the operator we have register. Speed Very Slow : 0.7 Kbps Copyright @ CBPGECJ 5
- 6. 1G Mobile Standards Name Place NMT (Nordic Mobile Telephone). Nordic countries, Switzerland, Netherlands, Eastern Europe and Russia. RTMI. Italy. AMPS (Advanced Mobile Phone System). North America and Australia. TACS (Total Access Communications System). United Kingdom, C-450 in West Germany, Portugal and South Africa. Copyright @ CBPGECJ 6

- 8. Second Generation (2G) History This network’s are Developed in 1991.The 2G introduced services for mobile, starting with SMS text messages.2G has been superseded by newer technologies such as 2.5G, 2.75G. Use This 2G Network’s are based on digital radio signals Example:- GSM: Global System for Mobile Advantage 1.Going all-digital allowed for the introduction of digital data services, such as SMS and email. 2.Greatly reduced fraud. With analog systems it was possible to have two or more "cloned" handsets that had the same phone number. Speed 10 to 256 Kbps Copyright @ CBPGECJ 88
- 9. third Generation (3G) History The 3G Network’s first commercial launch of 3G was also by NTT DoCoMo Apan on 1st October 200. Next 3G network operator in the USA was Verizon wireless in October 2003. Data Rates IMT-2000 will provide higher transmission rates: a minimum data rate of 2 Mbit/s for stationary or walking users, and 384 kbit/s Security 3G networks offer greater security than their 2G predecessors. By allowing the UE (User Equipment) 3G networks use the KASUMI block crypto instead of the older A5/1 stream cipher. However, a number of serious weaknesses in the KASUMI cipher have been identified.

- 10. 3g adoption Copyright @ CBPGECJ Country Adoption Europe The 3G operators should cover 80% of the Europe national populations by the end of 2005. Iraq Mobitel Iraq is the first mobile 3G operator in Iraq. It was launched commercially on February 2007. Turkey Turkcell, Avea and Vodafone launched their 3G networks commercially on 30 July 2009 at the same time. Turkcell and Vodafone launched their 3G service on all provincial centres. Avea launched it on 16 provincial centres. Philippine s 3G services were made available in the Philippines on December 2008. Syria MTN Syria is the first mobile 3G operator in Syria. It was launched commercially on May 2010. Africa The first African use of 3G technology was a 3G videocall made in Johannesburg on the Vodacom network in November 2004. The first commercial launch was by Emtel-ltd in Mauritius in 2004. In late March 2006, a 3G service was provided by the new company Wana in Morrocco. India In 2008, India entered the 3G arena with the launch of 3G enabled Mobile and Data services by Government owned Bharat Sanchar Nigam Ltd. (BSNL). Later, MTNL launched 3G in Delhi and Mumbai. Nationwide auction of 3G wireless spectrum was announced in April 2010. Ref B.Jaikumar, Manaloor 10
