upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing
GSM and WCDMA-HSPA and HSPA+ systems.

 Future developments could yield peak throughput of the order of 300 Mbps



LTE Technology

LTE employs a new modulation technique on the radio interface - OFDM (Orthogonal Frequency Division
Multiplex), together with MIMO (Multiple Input Multiple Output) antenna technology

OFDM splits the information into multiple narrowband
subcarriers, allowing each of them to carry a portion of the
information at a lower bit rate, making OFDM a very robust
modulation, particularly in multipath scenarios, like urban areas

MIMO technology creates several spatial paths on the air
interface between the network and subscriber, so these paths
can carry the same or different streams of information, which
allows an increase in either the coverage (due to higher Signal to
Noise Ratio (SNR) at the receiver) or user data throughput

Evolution of the 3GPP Core Network
- SAE
The 3GPP core network has also undergone System
Architecture Evolution (SAE) in the same timeframe The architecture is based on an
as LTE, optimizing it for packet mode and, in particular, evolution of the existing GSM/WCDMA core
for the IP-Multimedia Subsystem (IMS), which supports network, with simplified operations and
all access technologies, including fixed wire-line access. smooth, cost-efficient deployment

This allows:
 Improvements in latency, capacity, throughput
Simplification of the core network, and optimization for
IP traffic and services, and expected growth
Simplified support & handover to non-3GPP access
technologies

The result is the evolved packet system (EPS) that
consists of the core network part, the evolved packet
core (EPC) and the radio network evolution part, the
evolved UTRAN (E-UTRAN), i.e. LTE. The EPS is Source: Ericsson

LTE commercial networks - performance

Signals Research Group conducted the first ever extensive
independent drive test evaluation of a commercial LTE network,
assessing the performance of the TeliaSonera LTE networks in
Stockholm and Oslo, and reported to GSA: “While still in its infancy,
commercial LTE networks in Stockholm and Oslo already
outperform many fixed broadband connections, offering average
data rates of 16.8Mbps (peak = 50Mbps) and 32.1Mbps (peak =
85Mbps) in 10MHz and 20MHz, respectively. Measured data rates
would have been even higher if it had not been for the stringent test
methodology, which focused almost entirely on vehicular testing.”
Signals Research Group, LLC
“Signals Ahead,” March 2010 report.



LTE network and technology trials –
some examples

Pre-commitment Trials – summary (GSA)
Many LTE trials are on-going worldwide. A trial is usually a
scheduled activity prior to planned commercial deployment.
Sometimes an operator has agreed to undertake a trial but
not decided i.e. committed to launch a commercial service.
The Table (left) lists cases where a trial is announced but a
firm commitment from the operator for a post-trial
commercial rollout is not available at this time.

“Evolution to LTE” paper



LTE eco-system
- platforms, user devices

Mobile phones, computer and consumer electronic
devices including notebooks, netbooks, ultra-mobile
PC’s, gaming devices, cameras, and PMPs will
incorporate embedded LTE connectivity.



Voice over LTE
LTE is likely to be deployed with a focus on data services connectivity for PCs, netbooks, etc
 Voice service will be introduced as a second step
 The One Voice initiative – announced on November 4, 2009, aims for industry agreement on
a harmonized way to implement voice and SMS over LTE, based on existing standards.
 The GSMA VoLTE (Voice over LTE) initiative was formally announced at the Mobile
World Congress on 15th February 2010. In establishing the VoLTE initiative, GSMA has
adopted the work of the One Voice Initiative as the basis of the work to lead the global
mobile industry towards a standard way of delivering voice and messaging services for
Long-Term Evolution (LTE). Using IP Multimedia Subsystem specifications developed by
3GPP as its basis, GSMA have expanded upon the original scope of One Voice work to
address the entire end-to-end voice and SMS ecosystem by also focussing on Roaming
and Interconnect interfaces, in addition the interface between customer and network.

Spectrum for LTE deployments

 An operator may introduce LTE in ‘new’ bands where it is easier to deploy 10 MHz or 20 MHz
carriers
 e.g. 2.6 GHz band (IMT Extension band) or Digital Dividend spectrum 700, 800 MHz
 Or in re-farmed existing mobile bands e.g. 850, 900, 1700, 1800, 1900, 2100 MHz
 LTE 1800 looks the most promising from re-farmed spectrum

 Eventually LTE may be deployed in all of these bands – and others later

 2.6 GHz (for capacity) and 700/800 MHz (wider coverage, improved in-building) is a good
combination

 LTE offers a choice of carrier bandwidths: 1.4 MHz to 20 MHz; the widest bandwidth will be
needed for the highest speeds

 Availability of new spectrum, particularly in the 2.6 GHz and Digital Dividend bands (700, 800
MHz), is a crucial factor for LTE deployments in many countries, and the regulatory conditions, and
will directly determine deployment and service launch dates in most markets.



700 MHz is a key band for LTE

 700 MHz LTE deployments include Verizon Wireless, AT&T Mobility, several regional players
 700 MHz spectrum availability will extend throughout Americas. This could be earliest in Chile
where LTE trials are planned by Entel PCS, Claro and Movistar. Subtel (regulator) expected to
soon launch a spectrum auction (2.6 GHz, 700 MHz)

 The Indian government has formed a task group to develop a national band plan at 700 MHz

 Consultations on future use of 700 MHz have commenced in New Zealand

Verizon Wireless

LTE commercial launch in 25-30 markets scheduled by end 2010
Nationwide by end 2013



2.6 GHz is a key band for LTE in Europe
and Asia
 Telenor and Netcom have been granted licences and 2.6 GHz spectrum

 TeliaSonera announced LTE commercial service launch in Oslo on December 15, 2009

 Teliasonera, Elisa and DNA have been granted licences for 2.6 GHz spectrum and are building
LTE networks in Finland

 TeliaSonera Sweden is deploying LTE using nationwide 2x20 MHz 2.6 GHz spectrum and
announced commercial service launch in Stockholm on December 15, 2009

 In Hong Kong, 2x15 MHz blocks of 2.6 GHz FDD spectrum have been auctioned, and won by
China Mobile, Genius Brand and CSL Limited

Several auctions of 2.6 GHz spectrum are scheduled or planned
throughout European markets during 2010 and later

800 MHz is a key band for LTE
- Digital Dividend spectrum
- Excellent for rural coverage and in building coverage
 The transition from analog to digital terrestrial television will release large amounts of spectrum
potentially for mobile broadband deployments – the so-called Digital Dividend

 In 2005 the European Commission identified the release of the digital dividend in Europe as a spectrum
policy priority. The Commission later called for efforts to be made at the World Radiocommunication
Conference (WRC-07) to give mobile services the same status as broadcasting services

 WRC 07 identified the 790-862 MHz band for mobile service in Europe, the Middle East and Africa

 Some countries have now confirmed the availability of the 790-862 MHz band (subject to allocation
processes i.e. auction), including Denmark, Finland, France, Germany, Sweden and Switzerland
 Germany recently became Europe’s first country to auction a package of spectrum which included
3 x 20 MHz digital dividend spectrum
 Other governments in Europe will follow in 2010 and beyond

 Many operators will deploy LTE in this band

Recent LTE spectrum auctions
Europe

Germany: After 224 rounds the spectrum auction ended on May 20, 2010 and covered 360 MHz
across 4 bands: 800 MHz (digital dividend), 1800 MHz, 2.1 GHz, 2.6 GHz. THIS WAS EUROPE’S
FIRST AUCTION OF DIGITAL DIVIDEND SPECTRUM. The 4 incumbents acquired 2.6 GHz
channels to be used for LTE. Telefonica O2, Vodafone and T-Mobile (but not E Plus)
additionally acquired 800 MHz digital dividend spectrum which they will use for LTE. The
800 MHz spectrum raised €3.576 billion, i.e. over 81.5% of the auction’s total value. Vodafone and
T Mobile are understood to be currently testing and deploying LTE in 800 MHz.

Netherlands: 2.6 GHz spectrum was auctioned in April 2010 and resulted in spectrum being
awarded to incumbents KPN, Vodafone, T-Mobile, and newcomers Ziggo 4 and Tele2. Unpaired
spectrum was left unsold.

Denmark: The auction of 2500-2690 MHz and 2010-2020 MHz spectrum was completed on May 10,
2010, with spectrum being awarded to Hi3G Denmark ApS; TDC A/S; Telia Nättjänster Norden AB;
and Telenor A/S. TDC has stated it could have a pre-commercial trial network running in June
2010. Information about the auction results is available here:

Migration options

Will HSPA+ deployments delay LTE rollout?

Many operators will invest in both HSPA+ and LTE. GSA sees no evidence of
HSPA+ uptake delaying commitments to deploy LTE. The success of
HSPA/HSPA+ in delivering mobile broadband will fuel demand to support
more customers and for even higher data throughputs including for new
applications, which LTE delivers. LTE brings the opportunity for additional
spectrum in Digital Dividend (700, 800 MHz) and 2.6 GHz bands, initially
giving comparable throughput capacity and performance, and will continue to
improve and also benefit from larger bandwidth deployments (up to 20 MHz).



LTE: a single global standard

 LTE is on track, attracting global industry support. The first LTE systems launched in 2009

 LTE is the natural migration choice for GSM/HSPA operators. LTE is also the next generation mobile
broadband system of choice of leading CDMA operators, who are expected to be in the forefront of service
introduction. A leading WiMAX operator recently announced it is shifting technology to LTE

 As a result of collaboration between 3GPP, 3GPP2 and IEEE there is a roadmap for CDMA operators to
evolve to LTE

 Successful handovers between CDMA and LTE networks have been demonstrated

 The LTE-TDD mode (TD-LTE) provides a future-proof evolutionary path for TD-SCDMA

 With LTE we have one single global standard, securing and driving even higher economies of scale and
importantly, simplifying roaming



LTE: some industry forecasts

 Research and Markets: by 2015, 380 million subscribers In the US, the EU-5 (France,
Germany, Italy, Spain and UK), Scandinavia, China, Japan and South Korea will have access to
mobile data through LTE networks

 Maravedis: The number of LTE subscribers worldwide will pass 200 million in 2015

 Strategy Analytics: the global LTE handset market will reach 150 million sales units by 2013

 ABI Research: by 2013 operators will spend over $8.6 billion on LTE base stations
infrastructure

 IDC: Spending on LTE equipment will exceed WiMAX equipment spend by end 2011, with
worldwide LTE infrastructure revenues approaching USD 8 billion by 2014

 Global mobile Suppliers Association (GSA): up to 22 LTE networks are anticipated to be in
commercial service by end 2010, and at least 45 by end 2012
