Telephony Broadband
A dominant means of global
broadband connectivity in the
Today ~ 1.2 Billion 2015: 2.1 Billion (?)
Today ~ 4 Billion near future
<80% 3GPP family> 2013: 1 Billion
400+ million 3G/WCDMA subs Today ~140 Million
(including HSPA)
New services are being introduced with the Internet at the heart the services
More powerful and enabled devices are becoming available
Digital content and in particular Digital Home continues to grow
Traffic and data volume is increasing significantly
Customer delight is absolutely essential
Users are adopting new habits
They are becoming more demanding on the quality and price

The Telecom / mobile business rather crowded sector
Europe in lead in mobile services: 119% in Europe, 87% in US and 84% in Japan
Telecom sector growth is slowing but still stronger than rest of economy
The sector growth in EU 26 (down from ~5% in 2004 to less ~ 1% in 2008, down to ~ 0 in
2009 and expected up to more than 1% in 2012)
Telecom sector share of GDP: ~ 3% in EU in comparison to other sectors, e.g. 11% of
transportation
Golden days of Telecom is over

Users are spending more time on the phone and internet
Traffic and data volume is increasing significantly
Average household spending on communication falls
Consumer pay less while getting better value -> they pay ~30% less than 5 years ago
Telecom seems to be the only sector delivering price decrease

* Revenue of 1 Mb voice is 25-40 times more than 1 Mb of data
Cost Vs Revenue does not add up Cap in flat rate
Lower revenue and margin Optimizations and other means
of traffic handling
User experience at risk
New revenue streams and
sources
Limit/control it More efficient deliveries in radio,
Turn it to revenue transport and core network
Bring the cost of it down Lower Capex and Opex
Lower Cost & Better Performance and New Revenue Streams Needed

Small cell
LTE and HSPA link level spectrum efficiencies • Operate at higher SNR, hence improve
close to theoretical limits the achievable spectrum efficiency
Other factors such as Coding & Modulation, • Also improves the QoS in the network –
MIMO and more spectrum contribute towards better user experience
higher capacity – Spectrum highest contributor! • Allows for faster, more felxible, cheaper
Spectrum is scarce and number of antennas is and easier deployment and operation
also limited
Frequency reuse is the key to keep up with exponential increase of traffic in the future
with limited spectrum availability

10. Think Big – Deploy Small Cells
2G and 3G networks (already provide macro coverage) LTE deployment drivers
LTE on 2.6 Ghz initially for high data traffic hot spots
Overlay micro/pico: fast to deploy and cheap and easy to install and operate
Address indoor coverage and capacity with LTE Femto enterprise 1 4
Improve macro (HSPA) coverage by overflowing the traffic to LTE
Use Digital Dividend later on & when the older technologies phase out for 2

13. Summary
Mobile Broadband is a reality and potentials are huge
There is a need for a new paradigm in mobile NW for cost effective
realisation of a true mobile broadband
LTE as a cost effective and future proof technology is a key to future mobile
broadband
New innovative solution, lower TCO, flexibility and scalability in the
deployment, simplicity and ease of operation will be key to the success of
LTE for mobile broadband
An overlay network with small cell deployment is the way forward
NW Sharing from site to spectrum sharing and eventually fully shared NW
with new differentiations will be the way forward
