Telecommunication Industry Scenarios: Evolution Waves
Internet Mobile Internet Internet of Things Tactile Internet
Transformation
Enabled global communications;
New form of entertainment;
Communication cheaper;
Communications everywhere;
Reachability of users and services;
Smartphone: becoming the main device for
access to content;
Smartphones => Beginning of Digital
Transformation;
Potentialized the use of Social Networks;
It will revolutionize all industrial segments
through electronic integration and
transaction, improving and optimizing its
production processes;
New innovation platform,
inaugurating a new economic moment;
Experience not only audiovisual, but full
immersion;
They will help users (humanity) in
complementing the perception of the
world by bringing more information
through sophisticated applications of
Augmented Reality and Virtual Reality;
Market
Voice traffic superior to data;
Voice is the most important service;
Non-Real-Time Applications
Fixed broadband growth is 42% (CAGR)
against 22% for mobile accesses;
Fixed Broadband> 64 kbps;
Default ADSL.1 = 1-8 Mbps
Growth of fixed broadband is 8% (CAGR)
against 33% for mobile broadband;
The number of MBB exceeds that of FBB in
2013;
Data traffic already outperforms voice
traffic. Data becomes more the most
important service;
In the next decade will be some tens of
billions of connected objects Explosion of
connected objects;
Services with low latency and security have
another relevance;
The 5G is promising with: expectation of 1
billion subscribers in less than 5 years of
operation; above 10 trillion in revenue
over the same period;
Latency becomes more relevant than

How Oi can fit new Low latency business
Oi is the operator that has the largest fiber optic network in the country with over 375,000 km of fiber cables for local and long
distance access;
The Company has a large long-distance fiber optic network serving more than 2000 Brazilian municipalities that are being upgraded
to support 100 Gbps speeds;
Oi has wide real estate facilities to support fixed and mobile networks, such as thousands of DSLAM & OLT cabinets, remote stages,
cell sites, buildings, etc.
All installation sites for TDCs follow criteria with double fiber approach - OTN Network Sites with reliable transmission approach;
Preference for sites with InnerCore and Outercore routers; Lower latency between sites; Better traffic distribution among regionals;

Summary
● Low Latency is becoming the king: The new wave for upcoming data services will have latency as main attribute. Low latency will allow inedited immersive/real time
services, becoming a new internet era: Tactile Internet. There are lot of technologies that enable low latency and catalyze Tactile Internet, such as: 5G,& Edge
Computing;
● Tactile Internet requirements: The immersive services experience depends on which type of human sense reaction is used, and vision reaction is one critical one,
which requires latency below 5 ms. New robotics control for Industry 4.0, will require a very low latency as well for proper production integration;
● Low Latency is a key enabler for 5G: Since to provide new Ultra Reliable Low Latency Communication Services till to allow algorithms to resource and interference
management and optimization for improve network capacity
● Edge Computing: It is the most important toll to reduce latency and consists to facilitate data processing at or near the source of data generation (Gartner). Thus, it
avoids the application data travels from the source to very far application and processing hosts;
● Reducing the Latency. The overall transport network proper dimensioned and configured can certainly improve the network low latency. However, new transport
architecture with simplification collapsing network layers, network aware multidomain control, automation etc. will be definitively key aspects for optimizing latency for
new critical applications. Improving processor performance using technologies beyond regular x86 servers, such as: GPUs, FPGA, DPDK etc, can reduce the time of
workloads and delivering/returning data to user application with readiness;
● Upcoming Low Latency Opportunities: Edge Internet economy (Low Latency Services) will be over $4.1 Trillion worldwide. The initial growth will come from Edge
serving existing use cases and will gradually be accelerated by the new use cases as the deployment becomes more widespread and developers learn to take
advantage of the Edge Internet architecture for applications across industry domains in all major markets;
● Edge Computing Opportunities: The opportunities for MNOs will be beyond of supporting directly services and use cases to end customers. It can open a several
opportunities such as Service Integration, Managed Services, IaaS/PaaS/SaaS, new collocation business modelling etc.
● Capex Optimization: Besides latency, in general Edge Computing can bring an immediate benefit around local traffic offloading that implies in reducing overall CapEx
cost. Higher Traffic Density can rapidly justify the Edge Computing deployment
● How Oi can help; Oi is the operator that has the largest fiber optic network in the country with over 375,000 km of fiber cables for local and long distance access; It has
a large long-distance fiber optic network serving more than 2000 Brazilian municipalities that are being upgraded to support 100 Gbps speeds; It has wide facilities to
support fixed and mobile networks, such as thousands of DSLAM & OLT cabinets, remote stages, cell sites, buildings, served by abundant optical transport network.
