    • TD- TD-SCDMA Evolution Klaus Maler CEO TD Tech Klaus Maler: TD-SCDMA Evolution
    • TD Tech: Company Overview With total investment over U. S. $100 Million 51% 49% HK JV 100% TD Tech was founded on Mar. 18, 2005 in Beijing with the full support from Government. Vision Drive the mobile world by leading Beijing TD-SCDMA; Our people make the Shanghai Headquarter R&D center difference! Mission Sales We focus on our customers’ needs; we timely provide top quality solutions; we build the bridge to success for our customers.. Customer Klaus Maler: TD-SCDMA Evolution

    • OUTLINE Evolution of TD-SCDMA Technology TD-SCMDA Network Deployment Klaus Maler: TD-SCDMA Evolution
    • Evolution of TD-SCDMA Technology Data rate LTE TDD DL/UL: 129/50 Mbps over 20MHz, R’8 DL/UL: 8.4/5 Mbps HSPA+ over 1.6MHz. R’8 MC-HSDPA/HSUPA (CCSA only!) DL/UL: 2.8/2.2 Mbps HSDPA/HSUPA over 1.6 MHz, R’5/R’7 LCR 384kbps over 1.6MHz, R’4 higher coverage/spectrum efficiency/peak data rate, lower delay/cost. 1999 2001 2002 2006 2009 2011 Klaus Maler: TD-SCDMA Evolution
    • 3GPP Release – 4/5/6/7 & CCSA Key technologies: CS voice p CS and PS Data p HSDPA: DL peak data rate per 1.6MHz is 2.8Mbps p MBMS: optimization of broadcasting capability p HSUPA: UL peak data rate per 1.6MHz is 2.2 Mbps p MBMS improvement: dedicated carrier MBMS, improved efficiency, wider p coverage N-frequency HSDPA: HSDPA over N-frequency system, improved peak data p rate. HSPA+ LTE Rel.7 Rel.6 2011 2009 2008 2007 Klaus Maler: TD-SCDMA Evolution
    • One Step Forward - HSPA+ Market Requirement: Higher peak data rate and increased spectral efficiency in deployed TD-SCDMA networks. TD Tech’s Solution: HSPA+ (Enhanced High Speed Packet Access) 8.4 Mbps in downlink, 5 Mbps in uplink over 1.6MHz (single carrier), equivalent p to 105 Mbps over 20MHz MIMO and 64QAM modulation as enabling technologies for high spectral p efficiency CPC (Continuous Packet Connectivity) will optimize the networks to support p VoIP, streaming and other real time services Cell FACH enhancement: Enable quot;always onlinequot; type services for UEs, which p allow for an excellent user experience in web surfing, chatting, gaming etc. HSPA+ LTE Rel.7 Rel.6 2011 2009 2008 2007 Klaus Maler: TD-SCDMA Evolution
    • MIMO for HSPA+: Multiple In – Multiple Out Receive Transmit NxM Channel processing processing N transmitting antennae and M receiving antennae system 2X2 MIMO system doubles spectrum efficiency. p Integration possible with existing TD-SCDMA smart antenna system, no change p in deployed antenna hardware Klaus Maler: TD-SCDMA Evolution
    • HSPA+ : Operator Benefits HSPA+ is a fully TD-SCDMA Rel.4/5/6 backward compatible technology p Protection of investment for the operators: HSPA+ is mainly software p upgrade, no change in infrastructure. Short time-to-market: quick response to the market requirement. p Operators can swiftly upgrade the existing network to HSPA+ in order to promote new services. Lower technical risk: HSPA+ is the gradual evolution from release p 4/5/6/7 so the technology itself is very mature and the network is evolved from the mature commercial TD-SCDMA network. HSPA+ is perfect solution for transitional period before LTE is p commercially available. Klaus Maler: TD-SCDMA Evolution
    • TDD Long Term Evolution New access technology and new system architecture for mobile radio network competitiveness in 2011 and 10 years beyond. Radio Side (LTE – Long Term Evolution) p Improvements in spectral efficiency, user throughput, latency n Simplification of the radio network n Efficient support of packet based services: MBMS, IMS, etc. n Network Side (SAE – System Architecture Evolution) p Improvement in latency, capacity, throughput n Simplification of the core network n Optimization for IP traffic and services n Simplified support and handover to non-3GPP access technologies n HSPA+ LTE Rel.7 Rel.6 2011 2009 2008 2007 Klaus Maler: TD-SCDMA Evolution
    • LTE: Main Features Key technology: MIMO and OFDM p PS domain only p Higher data rate in DL/UL, up to 128 Mbps DL in 20 MHz spectrum p Higher spectral efficiency p Enhanced MBMS p TDD frame structure inherit from TD-SCDMA, harmonious co-existence p TD Tech actively contributed in standardization process p Subchannels 1/T OFDM: Frequenc y Klaus Maler: TD-SCDMA Evolution

    • Smooth TD-SCDMA Network Migration Stage 1: Only TD-SCDMA Rural/Suburban Urban Dense urban Stage 2: HSPA+ data enhanced network with software upgrade, in 2009 Stage 3: LTE for hot spot coverage only, in 2011 Stage 4: Smooth migration to full LTE, after 2012 Klaus Maler: TD-SCDMA Evolution
    • Conclusions • Standardized and smooth upgrade path from existing TD-SCDMA networks towards future TDD based technologies • HSPA+ is the key technology to fill the gap between TD- SCDMA and LTE • HSPA+ will protect the operator investment and provides future proof services and performance • LTE TDD will co-exist and supplement TD-SCDMA for future deployments HSPA+ LTE Rel.7 Rel.6 2011 2009 2008 2007 Klaus Maler: TD-SCDMA Evolution
