LTE Market

LTE the common standard for next generation evolution for both WCDMA and CDMA operators

� LTE market is expected to be worth over €2.1Bn by 2012 according to ABI research (3Q 07)

� Analysys forecast over 400M LTE subscribers by 2015

Long Term Evolution but short Time To Market

� Start in 2009/2010 with major operators in Asia (NTTDoCoMo) and North America

� Western European will follow very closely

Initial deployments will focus on “Hot Zone” areas to maximise access to high data users

� Hot zone coverage will be driven by distributed BTS solutions for high density, high Data speed areas

Compelling LTE Performance

x10+

� Peak LTE throughput (high spectral efficiency)

� DL : 100Mb/s SISO; 173Mb/s 2x2 MIMO; 326Mb/s 4x4 MIMO for 20 MHz

� UL: 58Mb/s 16QAM / 86Mb/s 64QAM (based on 1 Tx UE)

� Spectrum efficiency

� DL : 3-4 times HSDPA for MIMO (2,2)

� UL : 2-3 times E-DCH for MIMO(1,2)

� Ultra low Latency

� Reduced call setup times (50-100ms) & RTT (10ms from UE to server) – wired user experience

� Capacity

� 200 users for 5 MHz, 400 users in larger spectrum allocations

� Flexible spectrum use maximizes flexibility

� 1.4, 3/3.2, 5, 10, 15, 20 MHz

� All frequencies of IMT-2000: 450 MHz to 2.5 GHzx4Latency

3G LTE CharacteristicsKey Principles

OFDMA (DL) / SC-FDMA (UL) : Robust modulation in dense environments

� Increased spectral efficiency

� Simplified Rx design � cheaper UE

� Scalable - go beyond 5 MHz limitation

MIMO: Increased link capacity

� Multiple-input, multiple-output UL& DL

� Collaborative MIMO (UL)

� Overcome multi-path interference

IP Core: flat, scalable

� Short TTI: 1 ms (2 ms for HSPA)

� Backhaul based on IP / MPLS transport

� Fits with IMS, VoIP, SIP

OFDM / MIMO - perfect long term marriage

Achieve considerable increase in capacity, peak rates & coverage

LTE Spectrum Vision

�LTE FDD deployable in any of the “3GPP” bands,… (and more)2.5/2.6 GHz, 2.3 GHz, 2.1 GHz,1900 MHz,1800 MHz,1700/2100 MHz, 1500 MHz, 900 MHz, 850 MHz, 700 MHz, 450 MHz

2500-2690 MHz (IMT 2000)Worldwide

Likely the only band with 20 MHz of spectrum available for LTE

Likely to be popular for worldwide roaming / device availability

900 MHz (GSM)- Europe

Operators are looking to migrate GSM 900MHz to LTE for rural scenarios (coupled with 2.6 GHz for urban)

2100 MHz (UMTS) - Asia

Initially for Japan, Korea, and maybe Europe

1700/2100 MHz (AWS) Americas

much interest in this band (1700 also for Japan)

470-854 MHz (Digital Dividend) - Mainly Europe

In competition with TV broadcasters and other technologies, due to larger cell sizes and better in-building coverage.

2100MHz – Japan/EU

1700/2100 – NAR

700MHz – NAR

2500–2690 MHz World

900MHz – Europe

1800MHz– Europe & APAC

1900MHz – NAR

850MHz – NAR

470-854MHz – Europe

(Digital Dividend)

450 MHz - Europe

1800 MHz (GSM)- Europe & Asia Pacific

Band not widely used, may see some re-farming, as for 900 MHz
