This document discusses the digital transformation of telecommunication networks through new technologies like NFV/SDN. It covers several topics: 1. The evolution of networks from 4G to 4.5G to 5G and the transition to virtualized platforms. 2. Scenarios driving network transformation like the internet of things and tactile internet that will require networks to support higher data rates, lower latency, and more connections. 3. The challenges of planning networks to support new technologies and services while balancing costs and optimizing resources.

Combination of huge number of Smallcells with fiber premises for connectivity
will bring an important concern for 5G infrastructure.
CRAN requires a tighter latency requirement for
interefrence control (e-ICIC and CoMP) - In general IP
backhaul transport cannot accomplish this latency level
in X2 interface.
CRAN unfolds complexity of capillarity for access
trasportation;
mmWave has a benefit to provide a very high capacity
but a short range coverage. Thus, multiplying the
number of Smallcells .

9. TCO Optimization & Reduction
● Simplification of IP hierarchies by providing a more "flat" network;
● Integrated planning of IP and Transmission networks;
● Service virtualization, network optimization, and on-demand allocation;
● Time-to-market agility;
● Programmability, service automation and speed of provisioning;
● Reduction of Network Costs (CAPEX and OPEX), with the reduction of the number of routers, spare-
parts, support contract, management license etc.
● Data Plane Control Plane Separation, vendor-independent unified control;
● Reduction of Engineering sites, main sites in the SDN-NFV model, Telco-Datacenters;
● Integration of IP core and TX (OTN + DWDM), full-mesh core (minimize latency and router interfaces),
SDN-WAN multilayer;
Typical Multilayer
Node
● Superchannel DWDM (400G / 1T) in the short and
medium term, single-carriers grouped with more
spectral efficiency.
● Same modulation of 100G, optimizes costs and
covers the same distance (span).

11. Lifecycle Management
Optimization of Total Costs:
Voice: 2G => 3G and Data: 3G => 4G bring significant savings in terms of total network costs;
Service balancing should take into account not only the network cost but the best use of an expensive
and scarce resource: spectrum;
Phaseout Management:
Today the mobile network has 3 access technologies (2G / 3G / 4G) that need to be realized:
management, planning, deployment, O & M, etc. multiplying operating costs (OpEx) and investments
(CapEx);
Some operators have already announced the end of either the 2G network or the 3G network aiming not
only to simplify and reduce operating costs, but also to re-use spectrum;
User Experience:
Churn is still the biggest challenge for operators, mainly due to the costs associated with acquiring new
users in a consolidated market.
The negative perception of services due to poor user experience is the main reason for the cancellation
and / or change of service provider.
Asset Management:
Technology evolution takes better advantage of features and brings a general improvement in overall
user experience. It also optimizes long-term investments and spectrum.
Technology and life cycle management is not simple, but it is one of the most important tools for
network strategic planning and even for tactical and operational planning.

13. Digital Transformation in Telecommunication Industry
Source: World Economic Forum 2017 : Digital Transformation Initiative Telecommunications Industry
Digital transformation in telecommunications could unlock more than $2 trillion in
value for the industry, consumers and wider society over the next decade.
● Accordingly with WEF 2017, SDN & NFV plays the central
role of Digital Transformation of Operator Network
● These technologies promise several important benefits: SDN
by separating the control and data layers; and NFV by
replacing complex network functions with easy-to-
manipulate virtualized software.
● Widespread adoption of these technologies will be driven
primarily by network cost reduction – 64% of operators
rated this as the main adoption trigger in a recent survey.
● It is estimated that SDN and NFV could generate savings of
25% to 75% of overall operator operating expenditure
thanks to significantly reduced provisioning, monitoring and
hardware costs.
● These technologies also promise to create value for
customers through flexible services, faster times to market
and improved user experiences.
● The ability to view and manipulate network functions on
demand, and at a granular level, will catalyse service
innovation and allow stronger collaborations between
customers and providers.
