Power Consumption Modeling and Analysis of Integrated Optical-Wireless Access...IJECEIAES
The integration of optical and wireless technologies at access networks are considered as a future solution which provide both high bandwidth and high mobility in an efficient way. GPON is a suitable candidate for optical backhaul due to the combination of higher data rates, greater split ratio and support for triple play services hence it offers maximum flexibility and cost advantages. On the other hand, recent developments of new radio access technologies and introduction of femtocell base stations provide the potential of offering broadband services and applications to everyone and everywhere. However, the power consumption of this network demands a particular attention because access networks are the largest contributor the network related electricity consumption. Therefore, in this paper we evaluate the power consumption of integrated optical-wireless access network which is based on independent ONU-BS architecture. We proposed a power consumption model for such network and the assessment has been done under different simulation scenarios. The constructed model will provide insight of the energy performance of the integrated access network so that in the network design process, focus can be done to the most energy saving strategies.

IMPROVED PROPAGATION MODELS FOR LTE PATH LOSS PREDICTION IN URBAN & SUBURBAN ...ijwmn
To maximize the benefits of LTE cellular networks, careful and proper planning is needed. This requires the use of accurate propagation models to quantify the path loss required for base station deployment. Deployed LTE networks in Ghana can barely meet the desired 100Mbps throughput leading to customer dissatisfaction. Network operators rely on transmission planning tools designed for generalized environments that come with already embedded propagation models suited to other environments. A challenge therefore to Ghanaian transmission Network planners will be choosing an accurate and precise propagation model that best suits the Ghanaian environment. Given this, extensive LTE path loss measurements at 800MHz and 2600MHz were taken in selected urban and suburban environments in Ghana and compared with 6 commonly used propagation models. Improved versions of the Ericson, SUI, and ECC-33 developed in this study predict more precisely the path loss in Ghanaian environments compared with commonly used propagation models.
The C-Band Alliance (CBA) proposal to clear 200 MHz (inclusive of a 20 MHz guard band) of C-band spectrum within 18-36 months of a final FCC order remains the fastest, most efficient way to transition a substantial amount of mid-band spectrum to terrestrial 5G mobile service

Cellular Connectivity: Changing the Landscape of the Cellular Backhaul Market...ST Engineering iDirect
The demand for connectivity is surging worldwide. Today more than ever, more people in more places are connecting for work, entertainment, social communications, and education. Increasingly, they’re using smartphones, tablets, and other easy-to-carry devices. And in many underdeveloped parts of the world, smartphones are often the only Internet access technology that’s both affordable and available.
As a result, mobile networks are poised to become the primary way in which we connect. According to the 2018 Ericsson Mobility Report, there will be 7.2 billion smartphone subscriptions by 2023. Total data traffic has surged by 400% from 2013 to today and is projected to explode another 500% by 2023.
Open Access Network (OAN) & Fixed Mobile Convergence (FMC): Foundation for a ...Hedi Hmida (PhD)
Abstract— Today, the increasing adoption of internet applications is driving the demand for high bandwidth communication services to individuals, homes and business premises. Fiber to the home (FTTH) is a future-proof fixed access technology that supports high bandwidth applications to the end user; however its deployment typically requires heavy capital investments that make for a significantly long payback period. For this reason, there has been an increase in fiber access network sharing initiatives between Network Operators. Analysis has shown that sharing the infrastructure on a wholesale basis delivers savings in capital and operational expenses; subsequently shortening the RoI (Return of Investment) period, enabling the faster delivery of services to a greater number of subscribers. This model is known as OAN; a horizontally layered network architecture and business model that separates the physical access of the network from the actual service provision. This paper presents an overview of OAN models, the most commonly shared infrastructure globally, and draws conclusions from experiences in the region. The paper outlines strategic business models, provides guidelines to overcome technical and regulatory implementation challenges and presents a new business model based on the combination of OAN and FMC concept that would enable the future deployment of networks capable of providing broadband services from multiple services providers (retailers) simultaneously.
Cloud Radio Access Network (C-RAN) has emerged as a promising solution to meet the ever-growing capacity demand and reduce the cost of mobile network components. In such network, the mobile operator’s Remote Radio Head (RRH) and Base Band Unit (BBU) are often separated and the connection between them has very tight timing and latency requirements. To employ packet-based network for C-RAN fronthaul, the carried fronthaul traffic are needed to achieve the requirements of fronthaul streams. For this reason, the aim of this paper is focused on investigating and evaluating the feasibility of Integrated Hybrid Optical Network (IHON) networks for mobile fronthaul. TransPacket AS (www.transpacket.com) develops a fusion switching that efficiently serves both Guaranteed Service Transport (GST) traffic with absolute priority and packet switched Statistical Multiplexing (SM) best effort traffic. We verified how the leftover capacity of fusion node can be used to carry the low priority packets and how the GST traffic can have deterministic characteristics on a single wavelength by delaying it with Fixed Delay Line (FDL). For example, for L1GE SM =0.3 the added SM traffic increases the 10GE wavelength utilization up to 89% without any losses and with SM PLR=1E-03 up to 92% utilization. The simulated results and numerical analysis confirm that the PDV and PLR of GST traffic in Ethernet network meet the requirements of mobile fronthaul using CPRI. For Ethernet network, the number of nodes in the network limits the maximum separation distance between BBU and RRH (link length); for increasing the number of nodes, the link length decreases. Consequently, Radio over Ethernet (RoE) traffic should receive the priority and Quality of Service (QoS) HP can provide. On the other hand, Low Priority (LP) classes are not sensitive to QoS metrics and should be used for transporting time insensitive applications and services.
Comparative analysis of LTE backbone transport techniques for efficient broad...TELKOMNIKA JOURNAL
In the bid to bring about a solution to the nagging problem associated with the provision of
ubiquitous broadband access, Next Generation Network (NGN) popularly referred to as Long Term Evolution
(LTE) network with appropriate network integration technique is recommended as solution. Currently,
Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) is the transport technique in LTE backbone
infrastructure. This technique, however, suffers significantly in the event of failure of IP path resulting in delay
and packet loss budgets across the network. The resultant effect is degradation in users quality of service
(QoS) experience with real-time services. A competitive alternative is the Internet Protocol/Asynchronous
Transfer Mode (IP/ATM). This transport technique provides great dynamism in the allocation of bandwidth
and supports varying requests of multimedia connections with diverse QoS requirements. This paper,
therefore, seeks to evaluate the performance of these two transport techniques in a bid to establish
the extent to which the latter technique ameliorates the aforementioned challenges suffered by the previous
technique. Results from the simulation show that the IP/ATM transport scheme is superior to the IP/MPLS
scheme in terms of average bandwidth utilization, mean traffic drop and mean traffic delay in the ratio of 9.8,
8.7 and 1.0% respectively.

Range expansion method on heterogeneous network to increase picocell coverageTELKOMNIKA JOURNAL
In this study, picocell planning was carried out on heterogeneous networks by applying the range expansion method. The case study was conducted in Coblong Subdistrict-Bandung on the 1800 MHz frequency. Heterogeneous network (HetNet) is a system that combines microcell networks and small cell networks (picocell and femtocell). The application of the range expansion method in picocell was aimed to broaden the scope of picocell. For the simulation, Atoll 3.3.0 software with observational parameters was implemented, including RSRP, SINR, throughput, and user connected. The planning results showed that the application of expansion method increased the coverage and quality of network, where the RSRP value ≥ -90 dBm was 97.72%, SINR ≥ 5 dB was 70.99%, uplink throughput was 17.80 Mbps, downlink throughput was 21.37 Mbps, and user connected was 99.2%.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

Abstract
A NREN, according to the World Telecommunication / ICT Development Report 2010 (ICT
Development Report, 2010), is a specialized internet service provider (ISP) “dedicated to
supporting the needs of research and education communities within a country”. Therefore,
the fundamental purpose of an NREN is to provide their dedicated services that address the
needs of their communities, with quality, adequate capacity and comprehensive coverage
throughout its region of operation.
However, not always the quality and adequate capacity, in all its coverage area, are possible,
mainly, for the lack of a good and robust telecommunications infrastructure. RNP, the
Brazilian NREN, compelled to improve its service offerings, has been facing this problem, by
building and sharing theses built infrastructures, through partnerships established with
Electric Power Transmission Companies (“Electrics”) and ISPs.
With “Electrics”, OPGW cable holders, RNP is deploying its new generation of backbone,
with multi-channel optical links, starting at 100 Gb/s, and significantly reducing costs,
eliminating, through win-win partnerships, IRU purchase or rent, of dark fibre or fraction of
spectrum, or even by simply hiring capacity for these links.
As well, with ISP, RNP is deploying metropolitan networks, based on joint construction, that
has reduced drastically theirs costs, yet with the benefit of the provider partner maintain the
infrastructure at no cost to RNP, guaranteed through a service level agreement (SLA).
This paper aims to present in more detail this strategy, sharing with others NRENs who also
suffer with the lack of a good and robust telecommunication infrastructure for offering their
services, this learning gained over the last years.
Keywords
Telecommunication infrastructure, joint construction, backbone, metropolitan network,
partnership.
2. 1. Introduction
A NREN, according to the World Telecommunication / ICT Development Report 2010, is a
specialized internet service provider (ISP) “dedicated to supporting the needs of research and
education communities within a country”. Therefore, the fundamental purpose of an NREN is
to provide their dedicated services that address the needs of their communities, with quality,
adequate capacity and comprehensive coverage throughout its region of operation.
However, not always the quality and adequate capacity are possible, mainly, for the lack of a
good and strong telecommunications infrastructure, so that its connectivity service has
“generous band”, for the use at education and research activities, and for their value-added
services to promote collaborative research work and facilitate teaching activities.
NRENs, where there are not so good telecommunications infrastructures, depend on public
policies to stimulate their construction, and the abundant supply of dark fibre, spectrum
portions or even high capacity, for their backbones, and last miles, to serve their user
institutions, with high quality and competitively priced.
RNP, the Brazilian NREN, compelled to improve its service offerings, has been facing this
problem by shifting its circuits hiring strategy for its backbone and their ''last miles”, or even
isolated and non-shared construction of metropolitan networks, by a strategy of building in
partnership and sharing infrastructure. For this, it has changed their processes of planning,
construction, operation and maintenance of its optical infrastructures.
Through partnerships established with Electric Power Transmission Companies (“Electrics”),
OPGW cable holders, RNP is deploying its new generation of backbone, with multi-channel
optical links, starting at 100 G b/s, and significantly reducing costs. Through win-win
strategy, it has eliminated the need for payment by the IRU or rent, of dark fibre or fraction
of spectrum, or even by simply hiring capacity for these links, swapping by investments in
lighting a dark fibre from the Electric and sharing the spectrum, fifth-fifty. The next sections
show the current and the backbone 2022, including this strategy of partnership with the
“Electrics” to deploy this new generation.
In addition, by building together with ISP, it has drastically reduced the cost of deploying
metropolitan networks and backhauls, where construction is required, with the benefit of the
provider partner maintain the infrastructure at no cost to it, guaranteed through a service level
agreement (SLA). Based on assumption of counterparts, both RNP and ISP, divide the cost
and the built infrastructure, fifty-fifty. Immediately in sequence, other sections details the
strategy related with metropolitan networks.
Finally, in the final section, it concludes, putting in highlights the benefits by deploying
optical infrastructures with this strategy, contributing to the improvement of the supervision
and control of the electrical systems, in case of the “Electrics” partnerships, and the
availability of infrastructure in metropolitan networks, promoting greater offer of internet
services to the general population through these ISPs partners.
3. 2. The current RNP backbone (2019)
RNP's nationwide infrastructure, known as Rede Ipê, consists of an Internet network with
points of presence in all 26 Brazilian states and, additionally, the Federal District, and
connections to the global Internet and major education and research networks of the rest of
the world.
RNP serves almost all public and several private research and higher education institutions in
the country, and increasingly relies on the Rede Ipê to develop its activities, with the
widespread use of advanced applications and collaboration platforms communication assisted
by interconnected computers.
Due to the increase of numbers of client connections, whether from new institutions or new
campuses from those already connected, as well as special communication and collaboration
needs, the continuous expansion of the national backbone infrastructure is essential. This
expansion requires the adoption of strategies to expand the infrastructure that quickly
accommodates the growing demand of these organizations.
Figure 1 below shows the fully “gigatized” Rede Ipê backbone, with all its circuits with
bandwidth from 1 to 100 Gb/s, at the end of September 2019. In addition to these illustrated
circuits, there are some contingency circuits, but not shown in Figure 1.
Figure 1 – Rede Ipê network topology in September 2019
4. This Rede Ipê backbone illustrated in Figure 1 currently contains own circuits, already
deriving from investments made in the infrastructure of one of the “Electrics” and by several
other circuits of different Brazilian operators, specially Oi, Embratel and Telebras.
3. The next generation of the RNP backbone (2022)
Backbone infrastructure growth is being planned since 2017, within the 100G backbone
deployment strategy, by 2022, based on the following points:
a) Infrastructure sharing agreement between RNP and Brazilian Companhia Hidrelétrica
de São Francisco (Chesf), with duration of 20-year, signed September 2016, which
covers approximately 6,900 km of optical fibers in the Northeast Region. Originally
planned to be illuminated in 3 phases over three years, was updated to be illuminated
in two phases, as shown in Figure 2 (phase I in cyan and phase II in green). The
implementation of phase I and the consequent commissioning took place in August
2019.
Figure 2 – Project Phases of the new 100G Backbone with Chesf (Phase I: Cyan, Phase II: Green)
b) Infrastructure sharing agreement between RNP and Brazilian Furnas Centrais
Elétricas (Furnas), with duration of 20-year, signed in November 2017, covering
approximately 4,600 km of optical fibers in Southeastern, Midwest and southern
Brazil. Originally planned to be illuminated in three phases over three years, as
shown in Figure 3, with phase I in cyan, phase II in yellow and phase III in red
connecting São Paulo to Foz do Iguaçu Brazil, frontier with Paraguay.
5. Figure 3 – Project phases of the new 100G backbone with Furnas (phase I: cyan, phase II: yellow and phase III
in red)
c) Infrastructure sharing agreement between RNP and Brazilian Eletrosul Centrais
Elétricas (Eletrosul), with duration of 20-year, signed in January 2018, covering
approximately 5,000 km of optical fibers in Southeastern, Midwest and Southern
Brazil. It is designed to be illuminated in four phases over three years, as shown in
Figure 4, with phase I in cyan , phase II in red,, phase III in yellow, and phase IV in
blue.
6. Figure 4 – Project phases of the new 100G backbone with Eletrosul (phase I: cyan, phase II: red, phase III:
yellow and phase IV: blue)
d) Other infrastructure sharing agreements that RNP has with other power transmition
companies, often with duration of 20-years, for the use of fiber optic pair of its
OPGW optical cables, routes in the Midwest, North and Northeast, specially with the
Taesa, signed in May 2019, which includes the Araraquara – Londrina, and Brasília -
Salvador routes. These routes are important for the connection of the Southeast to the
South region and Midwest and Northeast jointing the two optical infrastructures of
Furnas and Eletrosul and Brazilian capital(Brasília-DF) and Salvador, Bahia state
capital, respectively, as shown in Figure 5, and to be illuminated in a single phase.
7. Figure 5 – Routes of new 100G backbone with Taesa (phase I – red and phase II - blue)
e) Agreement between RNP and Telebras, a Brazilian Public Telecommunication
Company, within the scope of the National Broadband Plan, established in early 2019
and effective for 15 years, for sharing optical infrastructure, which foresees RNP's
investments in optical modules, in swapping for use, without cost, optical channels in
the Telebras backbone optical infrastructure. With this agreement, RNP will have 14
circuits of 100 Gb/s for the backbone, mainly in the routes of the north and Midwest,
as shown in Figure 6, in the first quarter of 2021, being deployed over this and the
next year.
8. Figure 6 – Optical routes for new 100 G Backbone, derived from the Telebras agreement
f) RNP's 10 and 100 Gb / s optical channel swap agreements and capacities with
different regional providers, to obtain complementary backbone circuits that could not
be provisioned through the above agreements, with Telebras and the electricity sector
companies - Chesf, Furnas, Eletrosul and Taesa.
Figure 7 below illustrates the pursued 100G backbone for 2022 and the strategic partnerships
to deploy it.
In sequence, Figure 8 shows the 2022 backbone and, alongside, the configuration of
international connections until 2022, directly to the USA, Europe and Africa.

10. Figure 8 – 100 Backbone 2022 and the international links
11. All of the agreements with Power Companies (“Electrics”) - Chesf, Furnas, Taesa &
Eletrosul (OPGW holders), follow the same strategy:
Agreement for 20 years,
RoU (Right of Use) of 1 dark fiber pair
No IRU (Indefeasible Right of Use) direct payment
Counterpart: RNP lit up w/ 40 optical channels, 20/20 RNP/Power Company
Initially 2 X 100G, 1 X 100G each one
All routes of the Power Company, except Taesa
Initially, it was planned to implement phase I of these partnerships with the Power
Transmission Companies (Chesf, Furnas and Eletrosul) in 2018 and 2019. However, due to
the difficulties of making resources available to implement them, it was only possible, until
now, the implementation Chesf Phase I, completed in July 2019, as shown in Figure 9, and
the beginning of the implementation of Furnas and Eletrosul Phase I, expected to be
completed in December, 2019, as shown in Figure 10.

12. Figure 10 – Phase I - Furnas green and Phase I Eletrosul - red, in progress, of the new 100G Backbone 2022,
respectively, with Furnas and Eletrosul
In order to meet the network implementation deadline (Q1 2022), mitigating the need to
increase recurring expenses with hiring new backbone circuits, RNP seeks to complement
investments of about US $ 18 million in three years, required for activation of the Southeast-
Midwest and South optical routes.
The other circuits of the new 100G Backbone 2022, not belonging to the Chesf, Eletrosul,
Furnas and Taesa phases routes, and not resulting from the partnership with Telebras for the
Midwest and North region, shall be supplied through exchanges with providers and
contracting with telecommunications operators and providers
As RNP is deploying its backbone with multiple optical channels available along several
routes, it permits to share the backbone built with regional ISPs and States
Information Highways (“Infovias”)
4. The Metropolitan Network Deployment Program (Redecomeps)
The Redecomep (Community Education and Research Networks) Initiative is part of a
broader Ministry of Science and Technology, Innovations and Communications (MCTIC)
action aimed at deploying high-speed optical networks in the country's major metropolitan
regions, capitals, and major inland cities with two or more public institutions of education
and research - federal and state.
In capital cities, these networks connect directly to RNP's Points of Presence (PoPs). Inside,
these networks connect to Aggregation Points (PoA), which, in turn, are connected to RNP
Points of Presence (PoP).
The Redecomep Initiative, coordinated by RNP, supported by its Brazilian Regulatory
Agency SLP (Private Limited Service) License authorization, aims to deploy optical
infrastructures in cities and metropolitan regions, linking research and higher education
institutions. The network deployment model foresees the construction of entirely new
infrastructure and / or the use of existing ducts, cables and optical fibers, through partnerships
13. for joint construction, sharing and maintenance.
Redecomep networks deployed in the interior are connected to the RNP State PoP through
transport circuits, initially at 1 Gb/s and 10 Gb/s, and 100 Gb/s transport circuits in the
medium term. To assist the operation of the PoP in each capital, RNP implements PoAs
(Aggregation Points) at the Redecomeps of inner cities, at one of the participating institutions
of the network, preferably at a federal or state public university campus or headquarters in
these cities. A PoA supports the PoP in the capital, for attending the final service to their
institutions remotely.
There are currently about 40 operational Redecomeps throughout Brazil, distributed in
capitals and inner. Figure 11 shows the locations where there are Redecomeps, deployed until
July 2019.
Figure 11 – Redecomep locations deployed, July 2019.
Table 1 shows the locations and the current status of Redecomeps. About 860 institutions are
currently connected to these networks. Except the networks of São Paulo, Belo Horizonte,
Ouro Preto and Mariana, which are IRU - Indefeasible Rights of Use in the market; and João
Pessoa and Porto Velho, which are the result of Technical Cooperation Agreements between
14. RNP and State Governments, all the others are their own constructions.

15. 5. The New Metropolitan Networks Deployment Strategy and the
Expansion of Existing Redecomep Networks
Initially, these metropolitan networks of the Redecomep Initiative were fully implemented by
itself RNP.
From 2016, the new established strategy required to implement such networks always in
partnership with ISP. After the pre-project of a network, the partner ISP is selected through a
bidding process to implement it.
ISPs wishing to submit proposals for joint construction in the locations covered by the
Redecomep Initiative should consider, in the bidding process, the required number of fiber
pairs for the RNP.
RNP acquires the optical cables required to deploy a network, and the selected ISP takes over
its launch, including the purchase and mounting of pole mounting accessories when the
method is for aerial cabling. After deployment, the RNP and the selected ISP share the
optical cable. In addition to sharing, the ISP is responsible for maintaining the network core ,
accesses and their future extensions of the deployed network, according to SLA agreed
between the parties.
In order to ensure with the electricity utility the assignment of the right to use pole space,
RNP normally agrees with the utility to assign, in return, 1 (one) or 2 (two) pairs of fiber for
it unrestricted use.
RNP also accepts the proposal to share existing ISP network infrastructure for deployment of
its networks. In such cases, ISPs wishing to submit proposals for sharing their existing
infrastructure in the localities should detail the infrastructure they may have, and the
conditions for sharing, while paying attention to the minimum amount of fiber required by
RNP. In this case, the original owners of their respective optical infrastructures themselves
must maintain shared networks.
The following are possible cases and conditions of sharing expected to be received in the
detailed proposals:
1. ISP already has part of the infrastructure in the locality of RNP's interest, but

RO Porto Velho In operation Unavailable for swapping.

16. it is interested in expanding it and, therefore, proposes to build jointly, as
described above, complementary, to meet RNP's points of interest, according
to the topology agreed between the yielding fiber pairs where it already has
infrastructure.
2. ISP already has the full infrastructure in the locality, which meets RNP's
points of interest, according to a topology agreed between the parties, and
proposes to share it, assigning fiber pairs throughout its infrastructure, and
proposing to receive, in exchange, as counterpart, fiber pairs in existing RNP
networks, from Table 1
The possible swap may be made, Km X Km, in the ratio of 1: 1 or 1: X, if one side considers
its given infrastructure of higher value than the received infrastructure. This can occur if the
locations are of significant size difference between them. RNP already has experience in
barter and practices market valuation, facilitating the measurement of the value of the
infrastructure involved in the barter (Grizendi, 2019).
The fiber exchange strategy with ISPs is also practiced for the expansion of existing
metropolitan networks and even for their maintenance. In case of:
Swapping of fiber pairs vs. maintenance in the same location, RNP: cedes 1 (one)
fiber pair, ISP: undertakes to provide maintenance under SLA: Examples: Manaus,
Rio de Janeiro, Porto Alegre;
Swapping of fiber pairs in same/different location(s) or long-distance fiber, fiber x
fiber (km-pair) in the same (1:1) or different location (1:n); fiber x fiber (km-pair) of
metro network for long-distance fiber (1:n)
Figures 12 and 13 below exemplify, respectively, a metropolitan network constructed in
conjunction with ISP and another expanded metropolitan network through ISP fiber
exchange.

6. Conclusions
As seem, through partnerships established with Power Transmission Companies
(“Electrics”), OPGW cable holders, RNP is deploying its new generation of backbone, with
multi-channel optical links, starting at 100 Gb/s. At the same time, RNP is significantly
reducing costs, according as it has eliminated the need for payment by the IRU or rent, of
18. dark fiber or fraction of spectrum, or even by simply hiring capacity for these links.
Also by jointly building with ISP, it has drastically reduced the cost of deploying
metropolitan networks and backhauls, where construction is required, yet with the benefit of
the provider partner maintain the infrastructure at no cost to it, guaranteed through a service
level agreement (SLA).
As such, RNP is deploying optical infrastructures where they do not exist or are precarious
for providing services to their communities while sharing their infrastructure and
collaborating with public policy. In addition, with this strategy, it contributes to the
improvement of the supervision and control of the "Electrics" systems, and the availability of
infrastructure in metropolitan networks, promoting greater offer of internet services to the
general population through these ISP partners.
Concluding, by deploying optical infrastructures with these strategies, RNP improves its
infrastructure to provide better services. While same time, it contributes to the improvement
of the supervision and control of the electrical systems, in case of the “Electrics”
partnerships, and the availability of infrastructure in metropolitan networks, promoting
greater offer of internet services to the general population through these ISPs partners
(Grizendi, 2019).
