Second Generation: Second Generation Based on low-band digital data signaling 3 TDMA STANDARD GSM(Global System For Mobile Communication) PDC(Pacific Digital Celluler ) IS-139 Mostly based on Circuit Switched technology These are digital and expand the range of applications to more advanced voice services. Not suitable for web browsing and multimedia applications2.5 Generation: 2.5 Generation 2 ADVANCED GSM STANDARDS GPRS (General Packet Radio Service) Uses WAP HSCSD (High Speed Circuit Switched Data) NEW PDC STANDARD EDGE(Enhance Data GSM Environment) IS-935Types of mobile Internet connectivity : Types of mobile Internet connectivity Global systems for mobile communication (GSM) High speed circuit switched data (HSCSD) General packet radio services (GPRS) Third generation (3G) mobile Enhanced data GSM environment (EDGE) Public access WLAN Linked public access WLANsGlobal System for Mobile Communications (GSM) : Global System for Mobile Communications (GSM) First implemented in 1991 by Finland It is a combination of Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) It operates in the 900MHz and 1.8 GHz bands throughout the world (except America) In America it operates in 1.9 GHz bandEnhanced Data for Global Evolution (EDGE) : Enhanced Data for Global Evolution (EDGE) Also , called as Enhanced Data rates for GSM Evolution A radio based high-speed mobile data standards Enables services like multimedia emailing, Web infotainment and video conferencingGeneral Packet Radio Service (GPRS) : General Packet Radio Service (GPRS) Enhancement for GSM core networks that introduces packet data transmission It uses radio spectrum It provides always connectivity and greater bandwidth Worldwide roamingCode Division Multiple Access (CDMA) : Code Division Multiple Access (CDMA) Developed in North America It uses spread spectrum technology to break up speech into small, digitized segments and encodes them to identify each call It providing clearer voice quality with less background noise, fewer dropped calls, enhanced security, greater reliability and greater network capacity.Evolution towards 3G : Evolution towards 3GWhat is 3G Mobile? : What is 3G Mobile?3G Technology: 3G Technology 3 G 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. If we describe 3g is nothing but fast stream and high bandwidth.Slide 14: Basic Structure how 3G works. 3G Network Video Streaming Media Server 3G-324M Protocol Mobile Video Phone IP Voice Mail System SIP Video Phones PC Video Terminals M S C E1 - ISUP GATEWAY3G Capabilities : 3G Capabilities 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 flexibilityThe 3G Performance Advantage: The 3G Performance Advantage Time to download a 1 MB file: • Fixed line modem: 3 minutes • GSM cell phone: 15 minutes • Enhanced GSM phone: 1-5 minutes • 3G phone (outdoor): 21 seconds • 3G phone (indoor): 4 secondsSome Representative Current Wireless Options: Some Representative Current Wireless Options 3G Cellular (WCDMA) Frequency Division Duplex (FDD): Uplink and Downlink are separated in frequency – (“symmetric”) Time Division Duplex (TDD): Uplink and Downlink are separated in time – allows “asymmetric” traffic (adjust time slots in uplink and downlink) 3G Cellular (CDMA2000) Wi Fi 802.11a and 802.11b; HyperLAN2 2.4 GHz band WiMAX 802.16d (fixed); 802.16e (“portable”) 5.8 GHz band; 10 – 20 Mbps symmetrical BW Blue Tooth RF based LAN technology; 20-30 feet coverage 2.4 GHz band3G Applications: 3G Applications • Wireless Internet • Audio on demand • Video conferencing • Secure mobile commerce transactions • Traffic and traveling information - location specific Interactive news delivery (voice, video, e-mail, graphics) • Voice /High-quality audio • Data transmission services • Multimedia e-mail (graphics, voice, video) • Web browser – On-line services – Time schedules – Global Positioning Services/Geographical Information Systems3G Realities: 3G Realities A recent study by Herschel Shosteck Associates noted that operators that pay large amounts for spectrum will have to charge end users so much that adoption of 3G will be slow . Another study by Strategy Analytics agreed, predicting that, while wireless data revenues will soar, 3G networks will account for less than a quarter of that revenue by 2010. So-called 3G killer apps such as multimedia won't succeed , the second study said. Pent-up demand: Now there's the rub. Even NTT DoCoMo doesn't think there's much pent-up demand among consumers for 3G multimedia services, so it will target its initial 3G offering at business -- and price it accordingly.3G Summary : 3G Summary 3G mobile is a major opportunity for business, commerce and consumers Brings together the two fastest growing market sectors - Mobile and Internet Market, services and standards evolving from 2G to 3G Significant opportunities for value added content and service providersFuture of Communication (4G): Future of Communication (4G) Fourth generation mobile communications systems that are characterised by high - speed data rates at 20 to 100 M bps, suitable for high - resolution movies and television, virtual . Initial deployments are anticipated in 2006-2010 .Conclusion : Conclusion 1. 3G is for high speed networks for variety of data intensive applications. 2. 3G provides more advanced services like wide-area wireless voice Telephone, video calls and broadband wireless data and also it provides advanced multimedia access and global roaming. 3. Users are now able to make person-to-person calls, download data and do a variety of other tasks they never imagined possible all via their 3G cell phones. 4. 3G is giving way to new generation wireless networks i.e. 4G3G Mobile Phones : 3G Mobile PhonesSlide 24: ?By- Mayank Pratap Singh EC-3rd Year GLAITM: By- Mayank Pratap Singh EC-3 rd Year GLAITM THANK YOU You do not have the permission to view this presentation.
