LTE World Main evolution for 3GPP operators, successor to GSM and UMTS Focussed on address broadband needs for users, pure packet system focus Driven not as a technology but as a response to business

2 LTE World Main evolution for 3GPP operators, successor to GSM and UMTS Focussed on address broadband needs for users, pure packet system focus Driven not as a technology but as a response to business needs, influence of NGMN forum ensuring vendors don t over focus on technology at expense of business objectives Today: Operators already in trial, RFP/Qs, contract awards already beginning Major Terminal Vendors Major Infrastructure Providers Operators Other organizations Motorola, Nokia, NEC, LGE, Panasonic, Samsung, Sierra Wireless, Option, Novatel Alcatel-Lucent, Ericsson, Nokia-Siemens, Huawei Asia : Leading operators (Japan, Korea) Europe : All major operator families (Vodafone, T-Mobile, Orange in LSTI) North America: Verizon, New Entrants with AWS spectrum & CDMA operators 3GPP, LSTI (LTE/ SAE Trial initiative), NGMN (Next Generation Mobile Network) 3 Cambridge Wireless January 2009 WiMAX World Already commercially available, driven by IEEE standards vs 3GPP Strong demand for fixed and nomadic W-DSL type of services Driven by IT companies vs Telco driven LTE Large numbers of regional networks deployed, Sprint first to focus on nationwide build out Major FPGA/ASIC Vendors Major Terminal Vendors Major Infrastructure Providers Operators Intel, Runcom, Beceem, Sequans, TI, Philips Semiconductor Samsung, Nokia, Motorola, LG, Kyocera Alcatel-Lucent, Nortel, NEC, Nokia-Siemens, Huawei, AT&T, BellSouth, BT, KT, Deutsche Telekom, France Telecom, Vodafone, Sprint, Telefonica, TeliaSonera, Orascom, Telecom Malaysia, KDDI 4 Cambridge Wireless January

7 It s business not just technology User Needs Traffic Traffic & Revenue Divergence Spectrum Efficiency Revenues Traffic levels New Competitors Revenues Data Era Simplification Market & Technology pressures driving the need for LTE deployments Underlying factor is the need for improved Total Cost of Ownership Market Key Challenge #1: Affordability How to serve subscribers profitably? Market Key Challenge #2: Accessibility How to extend broadband into areas profitably? Market Key Challenge #3: Versatility/More Broadband How to optimize the network for broadband and multimedia? 13 Cambridge Wireless January 2009 How to optimize the network for broadband and multimedia? LTE macro Voice driven coverage supports high mobility Networks Aren't About Macro Cells Anymore Data driven capacity Higher capacity and uniform user experience LTE small LTE cells small in & out cells door Macro Macro cooperation Technology relationship Femto Macro cooperation Small cells cooperation New generation terminals and data applications require uniform user experience and progressively higher and higher data rates Implies: to limit load & re-use then introduce inter cell cooperation to introduce hot spots to introduce small cells 14 Cambridge Wireless January

8 How to extend broadband into areas profitably? Spectrum is a major profitability factor, driving both capex spend and revenue potential Business challenge is to balance coverage cost / capacity cost with subscriber needs What is my strategy? High Coverage, then Low frequency band But limited capacity and lower bandwidth High Performance High frequency band Limited area, but high bandwidth Maximise my Spectrum Do I need 20MHz or will 5MHz be enough? Do I buy new or refarm GSM/UMTS spectrum? High Coverag e Low Capacity 15 Cambridge Wireless January 2009 How to extend broadband into areas profitably? Today LTE step 1 New spectrum application LTE step 2 Free 900 MHz for LTE 900 MHz 12 MHz 1800 MHz 5 MHz 2100 MHz 10 MHz (FDD) 2600 MHz 20 MHz 900 MHz 3 MHz Smooth LTE introduction in existing bands in 2100 MHz - Free 900 MHz needs for 1800 MHz contiguous coverage, but will provide favorable range 900 MHz 10 MHz 1800 MHz 15 MHz 2100 MHz 15 MHz (FDD) 2100 MHz 5 MHz 900 MHz 10 MHz Or 1800 MHz 15 MHz GSM UMTS LTE - Free 1800 MHz more adapted to hot spots capacity driven scenario 16 Cambridge Wireless January

9 How to optimize the network for broadband and multimedia? Dynamic not Static Networks Designing networks for the average or the peak busy hour means wasting resources Networks must become dynamic and adapt demands of users and the densification of networks Self Optimising Networks (SON) will simplify network operations by allowing dynamic configuration significantly improving TCO SON capability will improve network performance and subsriber satisfaction by adapting to changes in demand & reduce opex (e.g. powering down the BTS during quiet periods) SON allows plug-and-play configuration and optimisation for easy network introduction Traffic TCO Designed for average SON optimised config Time Typical TCO improvement due to SON 17 Cambridge Wireless January 2009 In Conclusion Technology is important, but it must serve the business need WiMAX or LTE there is space for both, operator focus and user segmentation will be a key influence There is a clear need for mobile broadband, driving the need for network evolution 18 Cambridge Wireless January
