  5. 5. Cross-industry Penetration and Intensifying Competition Carriers compete on a broader scale Expanding into the IT service field to create value for business users Expanding into content & entertainment and other fields to create value for end users Applications IT Infrastructure Mobile Fixed Voice/Data Content, Entertainment Broadband Internet
  6. 6. Market News ……… •The 2033 concept would allow for the device to capture memories directly from the user’s brain, through a process Motorola calls "organic memory capture". •Rel-8 introduced dual-carrier HSDPA operation in the downlink while Rel-9 similarly introduced dual-carrier HSUPA operation in the uplink and also enhanced the dual-carrier HSDPA operation by combining it with MIMO. •A reported 130 operators around the world have written LTE into their technology roadmaps. In December 2009, TeliaSonera launched the world’s first LTE networks in Norway and Sweden and an estimated 17 operators are expected to follow in its footsteps in 2010. •“LTE must efficiently and seamlessly coexist with existing wireless technologies during its rise to becoming the leading next-generation wireless technology.” •"The demand for LTE femtocells is unquestionable. We are already seeing operators asking for small cell access points to start testing in the second half of this year. Femtocells represent the key to avoiding the difficulties surrounding the first 3G deployments where roll-outs cost too much, took too long and did not meet user expectations •India's mobile phone companies added an average of nearly 15 million subscribers a month in 2009 to bring the total number of cellular users to 525.15 million - up 51.4 percent from December 2008. •HSPA+ was generally the most efficient way of upgrading use of bandwidth already in use and was likely to dominate in the short term at least, with an estimated 1.4 billion subscribers worldwide by 2013, around ten times the estimated take-up of LTE. •HSPA+ release 7, which became available last year, uses MIMO technology like that in 11n Wifi to help take the peak downlink throughput to 28Mbps, with 11Mbps on the uplink. Release 8, for which chipsets will become available this year, aggregates two carrier signals to bring peak data rates to 42Mbps on the downlink. •Release 9 will put two MIMO streams on each of two 5MHz carriers, aggregated to produce a 10MHz data pipe delivering 84Mbps on the downlink; the uplink uses simple aggregation to 23Mbps. A projected Release 10 would bring the peak downlink speed to 168Mbps, though this would require 20MHz carriers only available in the 2.5GHz and 2.6GHz bands.

  18. 18. VOICE VS INTERNET •Typical data rate required for a voice call – 10 Kbps (and reducing with time) – Constant bit-rate, static •Typical data rate for an Internet session – 1- 5 Mbps (and increasing with time) – Bursty traffic •There are 2 orders of magnitude (x100) difference in data rate requirements with expectations of lower prices •A network optimized for voice cannot simultaneously be optimized to handle a high number of broadband mobile Internet users – More spectrum needed for broadband subscribers to access the network – More backhaul required to handle traffic to & from the Internet •Internet business model requires lower cost per bit and significantly more capacity
  19. 19. SOLUTIONS TO INTERFERENCE • OFDM & OFDMA • Antenna Technologies – Adaptive Antenna System • Dynamic Frequency Selection • MIMO • Software Defined Radios
  20. 20. WHY OFDM IS FUTURE…….. • High peak-to-average power levels • Preservation of orthogonality in severe multi-path • Efficient FFT based receiver structures • Enables efficient TX and RX diversity • Adaptive antenna arrays without joint equalization • Support for adaptive modulation by subcarrier • Frequency diversity • Robust against narrow-band interference • Efficient for simulcasting • Variable/dynamic bandwidth • Used for highest speed applications • Supports dynamic packet access
  21. 21. 4G Network Requirement…. 1. A spectrally efficient system (in bits/s/Hz and bit/s/Hz/site), 2. High network capacity: more number of users per cell 3. A nominal data rate of 100 Mbit/s at high speeds and 1 Gbit/s at stationary conditions as defined by the ITU-R 4. A data rate of at least 100 Mbit/s between any two points in the world 5. Smooth handoff across heterogeneous network 6. Seamless connectivity and global roaming across multiple networks 7. High quality of service for next generation multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc) 8. Interoperability with the existing wireless standards, and 9. An all IP, packet switched network

  23. 23. What next ……. Addition of “Presence”, “Location” and “Mobility” is a winning key factor for Value Addition so future Revenues lies in: •Mobile Gaming •Advertising •Information sharing Specifically : •VoIP •PTT & PTM •Voice Messaging with Voice Attachment •Video conferencing •Video Monitoring •See what I see •Higher level of multi-play capability •Remote control of PVR •Mobile banking •User generated contents •Proximity payment
  24. 24. Requirement of Access Network •Super macro-cell for extra wide-area coverage of sparely populated areas such as remote villages, seas, or deserts. This type of base station shall support coverage of tens or hundreds of square kilometres and therefore, may require a different power, tower, and cabinet design. Furthermore, given its remote location, it needs to remain highly available in absence of regular maintenance. Deployment of this type of cell shall be dependent on operator’s internal deployment policies, but all such deployments shall meet all local regulations (such as maximum allowable power emission). Finally, please note that for this type of coverage, a new terminal design may be required. • Conventional macro-cell for wide-area coverage: This type of base station shall aim to re-use existing resources and support a smooth migration from legacy systems. These issues are described in more detail in subsequent sections. • Urban micro-cell for broadband metropolitan coverage: This type of base station is much less constrained by backward compatibility and migration issues (in terms of reuse of assets), as it will largely be deployed on new sites. This limits its size and antenna configuration to fit nicely into an urban landscape. • Indoors pico-cell for traffic hot spots: This type of base station is optimised for size and cost and not capacity, with variants for home, office, and mobile installations (e.g., access points). Furthermore, in this scenario the use of larger than 20 MHz channels spacing is not precluded in the future if frequency allocations allow it.
  25. 25. Requirement for Core Network •Access Management •Content Filtering •Efficient backhaul and core transport cost minimization •Efficient Routing •Enablers •Flexible support for different service classes •Harmonised IP Network Infrastructure •Latency •Lawful Interception •Open and Standardised Architecture •Operator Service and Access Management •Packet Inspection for Compliance and Policy Implementation •Roaming and Interconnection Support •Service Management •Support for Broadcast and Multicast Services •Support for Competitive Cost Structure •Support for Diverse Bearers •Support for Real-time & Streaming Services •Throughput •Value Based Charging

  27. 27. EVOLUTION OR DISRUPTION…….. First generation: Almost all of the systems from this generation were analog systems where voice was considered to be the main traffic. These systems could often be listened to by third parties. some of the standards are NMT, AMPS, Hicap, CDPD, Mobitex DataTac Second generation: All the standards belonging to this generation are commercial centric and they are digital in form. Around 60% of the current market is dominated by European standards. The second generation standards are GSM, iDEN, D-AMPS, IS-95, PDC, CSD, PHS, GPRS, HSCSD, and WiDEN. Third generation: To meet the growing demands in the number of subscribers (increase in network capacity), rates required for high speed data transfer and multimedia applications 3G standards started evolving. The systems in this standard are basically a linear enhancement of 2G systems. They are based on two parallel backbone infrastructures, one consisting of circuit switched nodes, and one of packet oriented nodes. Currently, transition is happening from 2G to 3G systems. Some of the 3G standards are EDGE and EGPRS (sometimes denoted 2.75G),CDMA 2000,W-CDMA or UMTS (3GSM), FOMA, 1xEV-DO/IS-856, TD-SCDMA, GAN/UMA, 3.5G - HSDPA, 3.75G - HSUPA. The ITU defines a specific set of air interface technologies as third generation, as part of the IMT-2000 initiative. Fourth generation: According to the 4G working groups, the infrastructure and the terminals will have almost all the standards from 2G to 3G implemented. The infrastructure will however only be packet based, all-IP. The system will also serve as an open platform where the new innovations can go with it. Some of the standards which pave the way for 4G systems are WiMax, WiBro, 3GPP Long Term Evolution and 3GPP2 Ultra Mobile Broadband.
  28. 28. THIS MEANS 4G IS ……. 4G is a short form of fourth-generation cellular communication system which provides end-to-end IP solution where voice, data and multimedia streaming can be served at higher data rates with anytime-anywhere concept. No formal definition is set to what 4G is, but the objectives that are predicted for 4G can be summarized in a single sentence: 4G will be a fully IP-based integrated system of systems and network of networks achieved after the convergence of wired and wireless networks as well as computer, consumer electronics, communication technology, and several other convergences that will be capable of providing 100 Mbit/s and 1 Gbit/s, respectively, in outdoor and indoor environments with end-to-end QoS and high security, offering any kind of services anytime, anywhere, at affordable cost and one billing.

  46. 46. BUZZ WORDS …IMS, VOLGA, LTE There are three different ways to deliver voice services in future ( viz LTE): •IP Multimedia Subsystem (IMS) is approved by the 3GPP but may be too immature to rely on for early deployment due to heavy cost, no IMS Roaming etc •Circuit-switch (CS) fallback, in which the 2G or 3G networks are relied on for voice services ( NSN) •Circuit-switch-over-packet, where the CS voice or SMS traffic is tunneled over LTE ( VoLGA which was formed on March 9, 2009 by : 1. Alcatel-Lucent (NYSE: ALU) 2. Ericsson AB (Nasdaq: ERIC) 3. Huawei Technologies Co. Ltd. 4. Kineto Wireless Inc. 5. LG Electronics Inc. (London: LGLD; Korea: 6657.KS) 6. Motorola Inc. (NYSE: MOT) 7. Nortel Networks Ltd. 8. Samsung Corp. 9. Starent Networks Corp. (Nasdaq: STAR) 10. T-Mobile International AG 11. ZTE Corp. (Shenzhen: 000063; Hong Kong: 0763) How LTE ( Long Term Evolution) can be implemented in a “Short-Term” and it is not “Evolution” but it is a “Fork-Lift Replacement”
  47. 47. WHEN TO DEPLOY IMS At the time being, the main triggers for deciding to deploy an IMS network are certainly the following: 1. Deployment or migration of an IPTV solution making use of IMS. 2. Deployment of a selected set of IMS-enabled fixed mobile services 3. Replacement of the legacy circuit-switched network for fixed telephony services (IMS used as PSTN emulation subsystem). 4. Deployment of a compelling set of mobile services through the Rich Communication Suite (RCS) or something else. 5. Deployment of a carrier grade VoIP solution for fixed residential customers, possibly with mobile/fixed convergence services including or not call contuinity between fixed and cellular access (knowned as voice call continuity). 6. Deployment of carrier grade enterprise services including for instance business trunking, IP centrex or fixed mobile convergence.
