LTE?
LTE™ is a radio access
technology for cellular
telecommunications
networks, developed by
the 3rd Generation
Partnership Project,
3GPP.

Why LTE?
2004:
3G (UMTS, HSPA) already a great
improvement on 2G (GSM, EDGE /
PDC / CDMA).
• Many networks deployed, growing
commercial experience, technical
standard still evolving.
But …

Whence LTE?
2004:
Already an awareness that even more
performant radio access technology
would be needed in the long term.
• So …
3GPP Long Term Evolution study
begins.

Whence LTE?
2005:
ITU forecasts that mobile data will
increase from 610 petabytes per year
in 2010 to 1450 PB/yr in 2020.
2010:
Actual mobile data is seven times the
ITU prediction of five years ago.
2012:
Demand for mobile data is huge and
rising.

Whence LTE?
2005:
ITU begins to develop its “IMT
Advanced” concept to take over from
where “IMT 2000” left off.
3GPP approves Technical Reports
25.912 and 25.913 covering,
respectively a feasibility study on the
evolution of the 3G radio access
technology UTRA*, and requirements
for the radio parameters of such a
technology.
* 3GPP bashfully coined the term Universal Terrestrial
Radio Access for its W-CDMA offering.

Conclusions of the 3GPP studies (1)
Throughput to be up to five times that
of 3G UTRA.
Improved spectral efficiency (bits per
second per herz of bandwidth)
• Improved radio technology (D/L OFDMA,
U/L SC-FDMA)
• MIMO (U/L & D/L)
Simple channel structure
• Catering for point-to-point and point-tomultipoint transmission
Simple radio resource control state
model
• Idle, Connected

Conclusions of the 3GPP studies (2)
And a simpler network architecture,
less expensive to install and maintain

LTE or E-UTRA?
Thus was launched 3GPP’s work item
on the long term evolution of its radio
access technology, termed
Evolved Universal Terrestrial Radio
Access, E-UTRA
• But the world’s technical press had
latched on to the term LTE – which
persisted!

This is LTE
The result was the Release-8 set of
36.-series technical specifications

Conclusions of the studies (3)
2008:
A further report 3GPP TR 36.913 laid
the foundations for an even more
powerful radio access technology

3GPP: from generation unto generation
1G = analogue cellular (TACS, NMT, …)
2G = GSM
• 2.5G = EDGE*
3G = UTRA
• 3.5G = HSPA
• 3.75G = HSPA+
4G = LTE
LTE-Advanced

* Some operators claim EDGE exhibits 3G capability.

functionality worldwide while retaining
the flexibility to support a wide range of
services and applications in a cost
efficient manner;
compatibility of services within IMT and
with fixed networks;
capability of interworking with other radio
access systems;
high quality mobile services;
user equipment suitable for worldwide
use (worldwide roaming capability);
Why LTE Advanced? (2)
LTE Advanced
• user-friendly applications, services and
equipment;
• enhanced peak data rates to support
advanced services and applications (100
Mbit/s for high and 1 Gbit/s for low
mobility.

How many megabits per second???
LTE Advanced
• user-friendly applications, services and
equipment;
• enhanced peak data rates to support
advanced services and applications (100
Mbit/s for high and 1 Gbit/s for low
mobility.
Compare these rates with
today’s wire line offerings
from ISPs.

So is LTE a technical success?
YES !
• LTE and of course LTE Advanced offers
always-on packet connection with
excellent throughput rates (better than
wire line).
• Use of femto cells (Home eNode-B) for
coverage of hard-to-reach areas or high
population density areas, or closed
subscriber groups for blanket coverage of
commercial/industrial sites can ensure
excellent quality of service.

But is it a commercial success? (1)
Commercial viability was a
requirement built in from the start of
the LTE study.
Around 100 LTE networks are already
in commercial operation in some 50
countries around the world.
A further 350 operators interested or
committed to opening LTE service.
19
© ETSI 2012. All rights reserved
But is it a commercial success? (2)
Some 28 million LTE terminals are in
operation (50% in the Americas).
Around 420 LTE terminals on the
market:
• Samsung (Galaxy SIII)
• HTC (One)
• Huawei (Ascend P1)
• Nokia (Lumia)
• Apple (iPhone5)
• Amazon (Kindles)
• …

But is it a commercial success? (3)
First UK LTE network from EE trialling
in London, to cover 16 cities by end
2012, 98% of population by end 2014.

Whither LTE? (1)
Improved antenna technology will
increase the level of MIMO and the
accuracy of beamforming / tilting.
Carrier aggregation will allow
consistently high bandwidth and
enable operators to make the most of
their fragmented spectrum
allocations.
Network infrastructure shared
between two or more operators will
reduce capital and operational costs
for operators.
22

Whither LTE? (2)
Machine-to-machine (“internet of
things”) communications will increase
total data communications
enormously.
• Does not necessarily need high speed
data or low latency for any one device,
but …
• There will be many millions of devices
competing for available bandwidth, so
high speed and low latency – and low cost
– will be vital.
LTE selected for the next generation of
public safety (blue-light) services in
the USA.

So is it all plain sailing?
Bandwidth is in short supply, though
regulators are continually making
more available:
• Digital dividend from closure of analogue
TV broadcasting
• Refarming of 2G and even 3G bands
• New allocation of spectrum to meet ever
rising demand
LTE is designed to operate in a large
number of bands* but not all
terminals yet support all bands (thus
hampering roaming).
* Commercial services currently operating in 700, 800,
850, 1700, 1800, 1900, 2100, 2600 MHz bands..

The greening of mobile
The standardization community has an obligation to look
at the impact of technology evolution on society.
3GPP is taking environmental issues very seriously.
Reducing the carbon footprint and improving energy
efficiency are key requirements for 3GPP Members.
• Socially responsible
• Cheaper to run
Dedicated feasibility study included in Release 10 on
energy savings management (3GPP TR 32.826) and a
guide to potential solutions for energy saving in LTE
networks (3GPP TR 36.927).

But that’s not all, folks!
A workshop held just before the 56th plenary meeting of
3GPP’s technical specification group on radio access
networks concluded that, for Release 12 and beyond, it
would concentrate on a number of topics such as
• Energy saving
• Cost efficiency
• Support for diverse application and traffic types
• Backhaul enhancements
• Small cell enhancements, including backhaul
• Self-organizing/optimizing networks
• Terminal-to-Terminal services (to meet public safety
service needs)
It would also continue its work on increasing capacity
(data traffic is predicted to double in each of the next
five years)
