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
