 Instantaneous uplink peak data rate of 50 Mb/s (2.5bps/Hz within a 20 MHz uplink allocation)

 Downlink: average user throughput per MHz, 3 to 4 times Release 6 HSDPA

 Uplink: average user throughput per MHz, 2-3 times Release 6 enhanced Uplink

 E-UTRAN optimised for low mobile speed: 0-15 km/h. Higher mobile speed between 15-120 km/h
should be supported with high performance. Mobility shall be maintained at speeds 120km/h-350km/h (or
even up to 500 km/h depending on the frequency band)

 Spectrum flexibility: scalable to operate in 1.4, 2.5, 5, 10, 15 and 20Mhz allocations: Uplink and
downlink, paired and unpaired

 Co-existence with GERAN/3G on adjacent channels: with other operators on adjacent channels:
overlapping or adjacent spectrum at country borders: handover with UTRAN and GERAN

 Increased peak data rates, with the potential for 100 Mbps peak downstream and 50 Mbps peak
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

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 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;
regulator Subtel expects to launch a 2.6 GHz LTE spectrum auction in December 2010, which is
earlier than originally expected, and up to 140 MHz may be available. It means LTE services could
be launched in 2012.
Anatel will auction 120 MHz of 2.6 GHz spectrum, most likely by mid-2013, while giving
operators the option to deploy LTE earlier should they acquire an MMDS operator who currently
holds spectrum. The 2.6 GHz band had been allocated to MMDS operators for pay TV, and they
will keep 70 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. DNA obtained 40 MHz of 2.6 GHz spectrum

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

 MVNO and cable operator Telenet is trialing LTE in Mechelen, ahead of the 2.6 GHz auction
expected in September 2010. Mobistar is also testing LTE.

 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

 The regulator MCMC plans to auction 3 blocks of 2.6 GHz spectrum for LTE in 2011, and is also
consulting on re-farming 850/900/1800 spectrum for 3G services
Several auctions of 2.6 GHz spectrum are scheduled or planned throughout European
markets during 2010 - 2011

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

 Several 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 was Europe‟s first country to auction a package of spectrum which included 3 x 20 MHz
digital dividend spectrum
 Other governments in Europe arefollowing in 2010 and beyond
 In June 2010, the Australian Government confirmed it would release 126 MHz of digital dividend
spectrum (694 – 820 MHz) due to be cleared by end 2013

 Many operators will deploy LTE in digital dividend spectrum

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.

LTE TDD

The LTE market includes TDD as well as FDD systems

“While the majority of LTE deployments today are using the FDD mode, the report
confirms significant operator interest in the TDD mode. LTE FDD and LTE TDD
are complementary technologies and standardized by 3GPP. A number of key
technology milestones have been demonstrated in recent weeks which confirm
how the LTE TDD system is maturing towards commercialization. The recently
concluded BWA spectrum auction in India has paved the way for early and large
scale introduction of TDD LTE into the world’s fastest developing market”

large-scale trial network covers the whole 5.28 square-km site, outdoors and in 9 pavilions and 2 demonstration
centers. Several products supporting the trial network are launched or planned including WWAN cards, routers and
dongles. Key milestones achieved in the trial include:

 Demonstration of LTE TDD HD video telephone in single 20 MHz spectrum with peak DL speeds of up to 80 Mbps
 Demonstration of VOD, video communication, and other high-speed mobile broadband apps
 Demonstration of 24-channel video streaming
 Mobile HD video conferencing between the trial network and another location
 Inter-Operability Test of multiple LTE TDD USB dongles in a single mobile network cell

China Mobile will establish 3 further trial LTE TDD networks in Qingdao, Xiamen and Zhuhai - beginning Q3 2010.
China Mobile is also partnering with foreign operators to establish trial LTE TDD networks overseas, including Taiwan.

India is a key market for LTE TDD following the BWA spectrum auction. Qualcomm through its JV with local partners is
committed to LTE TDD and anticipates commercial service from 2011. Some other BWA spectrum winners are finalizing
their technology choice, so more winners may also choose LTE TDD.
