  11. EVOLUTION OF MOBILE SYSTEMS • Pre Cellular – e.g. IMTS (Improved Mobile Telephone System) – • Analog FM System used in mid 1960s. • 1G - e.g. AMPS, TACS, ETACS, NMT – Partially digital, used • from early 1980s in 800 MHz-900 MHz bands. • 2G – e.g. IS 95, GSM – Fully digital, used from early 1990s, • in bands 800, 900, 1700, 1800 and 1900 MHz, Voice Centric • with limited data capabilities and SMS. • 3G – e.g. CDMA 2000, WCDMA – Supporting voice plus high • speed packet data services. • 4G - Fixed Mobile Convergence; Seamless Mobility; very high • data speeds

  12. PARADIGM SHIFT In 1G - emphasis was on technology, in particular on the evolution of network infra-structure to address the New World of mobility. In 2G - manufacturers were striving to meet consumer demand for ever smaller phones with longer battery life and advanced features. In 3G - focus will now be on content and multimedia applications. Voice telephony will be complemented by services beyond voice. In 4G - ‘service and experience’-centric

  15. What is the Third Generation ?Defining the Next Generation

  16. The ITU’s Vision for 3G • Future Public Land Mobile Telecommunications Service (FPLMTS) • (Initiative of the ITU since 1985 to define 3rd generation of wireless) • Difficult to pronounce, hence “FPLMTS” changed to IMT-2000 • IMT-2000 IS ABBREVIATION FOR INTERNATIONAL MOBILE TELECOMMUNICATION

  17. ITU Requirements • Small, Low Cost Pocket Terminals • Worldwide Roaming • Single System for Residential, Office, Cellular, Satellite,Environments • Data Services Delivery • Vehicular Environment: 144 Kbps • Pedestrian Environment: 384 Kbps • Indoor Environment: 2 Mbps

  18. KEY FUNCTIONS OF IMT-2000 *FULL RANGE OF SERVICES *UNIFIED ,SEAMLESS INFRASTRUCTURE *BROADBAND TRANSPORT *SELF -ADAPTIVE ,RE-PROGRAMMABLE TERMINALS

  19. IMT-2000 Terrestrial Radio Interfaces Key IMT2000 Requirements: • High Speed Packet Data • 144k - Vehicular • 384 - Pedestrian • 2Mb - Indoor • Global Roaming • UIM - Based on SIM IMT-2000 CDMA Direct Spread IMT-2000 CDMA Multi-Carrier IMT-2000 CDMA TDD IMT-2000 TDMA Single Carrier IMT-2000 FDMA/ TDMA cdma2000 1X and 3X UTRA TDD & TD-SCDMA) UMTS UWC-136/ EDGE DECT ITU-R Assembly has approved WiMAX as part of the IMT-2000 family of standards ahead of the ITU WRC 07 in Geneva.

  20. 3rd Generation Partnership Project TTC 3GPP for evolved GSM & UTRA TTC 3GPP2 for evolved ANSI-41 & cdma2000 3G Partnership Projects • Two partnership projects have been established to accelerate all aspects of 3G standardization • Main thrust of each project is to find commonality for their respective standards across regions • Global harmonization could enable: • lower overall costs • faster product cycles • faster operator implementation of 3G services

  21. 4 G As the first implementations of 3G are beginning to roll out, the shortcomings of 3G networks are already being discussed and the scientists/researchers have begun to talk of 4G (also referred to as ‘IMT-Advanced’ by ITU) which, at this initial stages, implies “improvement and the fixing of lingering 3G problems, apart from increasing data speeds beyond 2 Mbps”. Systems beyond IMT-2000 are commonly referred to as the Fourth Generation Networks (4G) or Beyond 3G (B3G) or IMT Advanced.

  22. 4G Vision There will not be a single network branded as 4G in the same way that there is 2G GSM or 3G UTRAN. Instead, 4G will be a collection of networks and a wide variety of smart devices communicating with each other. The 4G technology will provide for a collection of different kinds of multiple access networks in which a user can gain access to a portal on the Internet (or whatever the entity) by the most appropriate means. The user will not have to know which network provides the service. The smart device can analyze its environment and choose the best available service provider and technology (service discovery). Contd….

  23. Contd….. Both the network entities and the smart devices will be able to configure themselves so that they can adapt to new requirements. The emergence of fourth generation of mobile services will allow Users to connect to different networks depending on their location. For example, a handset could connect a wireless local area network (WLAN) when inside a building, switch to a 3G mast when outside, And connect to a standard network in areas with no 3G coverage. 4G is supposed to be an all IP Network with higher bit rates, enhanced Multimedia services, smooth streaming videos, worldwide Access/roaming capability, Intelligent software as driven technique. OFDM-UWB (Orthogonal Frequency Division Multiplexing-Ultra Wide Band) as representative standard, FDMA, TDMA, CDMA as Multi access techniques, low cost and tight security network.

  25. Indian Initiative • The Centre of Excellence in Wireless Technology (CEWiT) India, an autonomous institution, has been set up under a public-private initiative with a view to spearhead research within the country in the area of 4G technology. • Broadband Wireless Consortium of India (BWCI), is a strategic initiative of CEWIT with the objective of providing a common national forum for all stakeholders in the broadband wireless market in India with a view to co-ordinate activities within India and also to ensure adequate representation of the needs of the Indian broadband wireless market in global standard forums.

  26. Systems beyond IMT-2000 will encompass the capabilities of previous systems Mobility New capabilities of systems beyond IMT-2000 New High Dashed line indicates mobile that the exact data Enhanced access rates associated with IMT-2000 systems beyond IMT-2000 are not yet determined Enhancement New nomadic/local Low area wireless access 1 10 100 1 000 Peak useful data rate (Mbit/s) Denotes interconnection between systems via networks, which allows flexible use in any environment without making users aware of constituent systems Nomadic/local area access systems Digital broadcast systems

  28. WHY 4G ? Although 3G technologies deliver significantly higher bit rates than 2G technologies and contribute to ARPU growth for wireless data services, there is still more opportunity for wireless operators to capitalize on the ever-increasing demand for ‘wireless broadband’, even lower latency and multi-megabit throughput. Consequently, there is an expanding revenue opportunity from a growing pool of underserved consumers that can only be satisfied with next generation of mobile networks.

  29. Minimum Performance Requirements Increased spectral efficiency and capacity —(expected to deliver three to five times greater capacity than the most advanced current 3G networks) Lower cost per bit — (Increased spectral efficiency combined with the operational benefits of an all-IP network will reduce the cost per bit compared to 3G solutions). Improved quality of experience (QoE) —(Reduction in latency time, which will enhance the behavior of time-sensitive applications, such as VoIP, thus improving the user experience)

  30. Enabling technologies Orthogonal Frequency Division Multiplexing (OFDM) -OFDM is a special case of multi-carrier transmission, where a single data stream is transmitted over a number of lower rate sub-carriers. Multiple Input/Multiple Output (MIMO) increases peak throughput by transmitting and receiving multiple streams of information within the same spectrum.
