Why LTE? the demand for new MBB services

Over 10 million articles and over 6 million registered contributors on Wikipedia globally

45% of US and European workers are away from their desk more than 20% of their time

Over 4 billion songs,125 million TV episodes and 8 million movies have been purchased and downloaded from iTunes

412.3 years = Time it would take to view all of the material on YouTube.

More than 100 million video views are generated on YouTube every day.

The number of text messages sent and received each day exceed the population of Earth.

If Facebook is larger then Russia, with over 150 million active users.


Market factors

• Almost 5 billion GSM-UMTS users in the world• Almost all GSM operators have adopted EDGE technology• Over 600 million UMTS users in the world on 383 commercial networks• 380 operators in 155 countries offer HSDPA, 103 HSPA+ networks in service


Why LTE? the evolution of voice and traffic data

Traffic statistics for an UMTS-HSPA opeartor, market leader


Why LTE? the mobile Broadband market

“1000-fold percentage”

“+300% in 6 months”“In 5 Months +250%”

“Data traffic +40% per year”

“+500-600% annually”

“MBB to 25% of all subscribers ”

Why LTE? traffic growth in the USA

Source: “Managing Growth and Profits in the Yottabyte Era”,Chetan Sharma, July 2009. One Terabyte is 1000 gigabytes.

Ericsson's researches say that of the estimated 3.4 billion people who will have broadband by 2014, about 80 percent will be mobile broadband subscribers – and the majority will be served by High Speed Packet Access (HSPA) and Long Term Evolution (LTE) networks.

Why LTE? the benefits for the end users

› User benefits–

Mobile Broadband

›

Capacity in downlink >100 Mbps

›

Capacity in uplink > 50 Mbps

–

Data traffic and Internet access with tariffs comparable to fixed networks

–

Large variety and availability of handsets / devices

Tecnologie a confronto: tempo per il download di un DVD (4,6 GB)

GPRS (170 kbps) ⇒ T~ 3 giorni

EDGE (470 kbps) ⇒ T ~ 1 giorno

WCDMA/HSDPA (14,4 Mbps) ⇒ T ~ 1 ora

LTE MIMO 2x2 (173 Mbps) ⇒ T ~ 5 minuti


Why LTE? the benefits for operators

› Benefits for operators–

Simplified architecture –

Data and voice services furnished on a unified packet data infrastructure

–

Flexible use of radio spectrum (from 1,4 MHz to 20 MHz wide channels)

⇒ Reduced network cost

What does LTE mean?› LTE is an acronym for Long Term Evolution and refers to the recent Work

Item in the 3GPP standards body concerned with the evolution of the Radio Access Network.

› The evolutional course that has lead to LTE includes GSM/EDGE, WCDMA and HSPA Evolution (a.k.a. HSPA+)

› The LTE standard was first released in 3GPP Release 8.

What does sae mean?

› SAE is an acronym for System Architecture Evolution and represents the set of 3GPP specifications regarding the evolution of the Mobile Core Network.

› The objective of the SAE specifications is to define the future core network needed to support the services furnished by the LTE access network with a simplified architecture (with respect to the current 3G core network.)

› LTE and SAE are two aspects of the same evolution of the next generation mobile radio network.

Which services?

› Which applications will be possible with LTE?LTE technology continues in the direction undertaken by EDGE and WCDMA/HSPA for “always connected” Mobile Broadband.


LTE Handsets› Will new terminals be necessary?

Yes, new LTE terminals will be necessary. There will be multi-mode, multi-band terminals supporting GSM and WCDMA.


VOICE over IP

› What about voice?LTE/SAE supports Voice over IP (VoIP)


Fixed network vs. LTE

› Will LTE substitute Fixed Broad Band?Today LTE/SAE and fixed broadband technologies based on fiber access or ADSL can be seen as complementary.

Q4

When will LTE/SAE be available? From ericsson


What is 4G?

› IMT-Advanced: ITU requirements for 4° generation› Using “new” spectrum, i.e. Digital Dividend spectrum› But… ITU’s definition has softened


The future of lte

› LTE-Advanced (LTE-A): “Real” 4G› From 3GPP Release 10› Larger channels (at least 40 MHz) › Better performance: higher cell edge bit rates, less latency,

improved coverage› More than 1 Gb/s DL, more than 500 Mb/s UL
