Executive summary
The main objectives of cities are to improve citizens' lives, local economy dynamics and to attract new residents and
enterprises to establish locally. Strong evolutions in the fixed and mobile Internet connectivity have impacted the
expectations and behaviours of the people and the enterprises they are working in.
Digital services have become an important part of the daily life, crossing many activities within the day from
personalized morning news, thru latest updates on the transportation schedule (bus, train, road traffic), the operations at
work or schools even up to shopping at the supermarket. This digital revolution has also entered the area of services and
operations delivered by public services such as the city. To adopt this evolution, the Information Communication
Technology (ICT) platforms of the city services should be rethought and changed from the silo strategy to an integrated
approach. To achieve this goal, the ICT of the city should rely on a unified digital multi services infrastructure that
combines cable-based and wireless networks.
ETSI
6 ETSI TS 105 174-7-1 V1.1.1 (2017-06)
This digital multi services infrastructure is supposed to be economic, safe, multi purposes and future proof to enable the
sustainability of the city in regards to its digital services strategy and roadmap.
Up till now silo and vertical ICT have been mainly taken into consideration to deploy services. Since a few years,
various smart city efforts and initiatives suggest to strongly adopt a transversal approach in which services share a
common Internet Protocol (IP) network, co-operate between each other and furthermore enable third parties to leverage
the value offered by the power of data mining and big data processing.
A common and shared multi services architecture for the city's digital services is therefore needed to achieve the city's
goals and ambitions at reasonable cost of ownership and of operation while strongly taking into consideration the eco
efficiency of the different elements of the ICT deployments.
Introduction
Today digital life is leading major evolutions in the expectations that peoples and enterprises have towards the public
administrations. As the local representative and interface, the municipality is in front line. The boom of the mobile
Internet economy has created many new types of services which requires the city to evolve and adapt to such new
behaviours from their target audiences.
City parking or tourism attractiveness are two simple examples of such digital revolution. In both cases, one expect to
have access to digital services which respectively facilitate the discovery of an available parking place or to the
accessibility of local public transportation facility such as bus, tram and even city bikes.
These digital services have increased the requirements of the ICT infrastructures of the city and amplified the need for a
more sustainable information Technology (IT) design. Smart digital city parking service requires sensors to be deployed
within the field, that their real time status (busy of available parking place) are transmitted thru a data network and that
a digital service leverage this information to be made available to the driver but also to the financial department in case
of the parking usage has to be charged.
Today many city applications are to be seen as island or silo application and have their own network, own software
platform and as a results different operations and maintenances. A common architecture will reduce this multiplication
of networks and software solutions while improving the economical and energy efficiently costs.
The present document will contain information which covers topics such as physical network installation, network
transmission implementation, digital services deployments thru an energy efficiency Next Generation Network (NGN).

1 Scope
The present document details measures which may be taken to ease the deployment of smart new services and their
multiservice street furnitures of digital multiservice city within the IP network of a single city or an association of cities
administratively clustered. Furthermore, the suggested measures will enable to engineer a reliable common networking
infrastructure which can improve the Total Cost of Ownership (TCO) for the public administration while improving the
energy efficiency of the overall deployment.
The present document also lists the requirements which have led to this common architecture.
Clause 4 identifies and presents a general overview of a city from small entity to significantly large municipality
clustering several cities and villages.
Clause 5 presents the pursued objectives behind the concept of smart city.
Clause 6 describes the general theoretical pillars which bears the engineering requirements to deploy a digital multi
service city.
Clause 7 identifies the general needs from the cities.
Clause 8 of the present document present a suggestion of an engineered digital multiservice city.
This will enable the proper introduction and implementation of a new service, application or content within the city
digital portfolio on a unified energy efficient network, though it is not the goal of the present document to provide
detailed standardized solutions for network architecture.

4 General overview of a city
4.1 Reaching sustainability thru digital multiservice city
networks
Municipality facilities range from a single premise to multiple buildings located across the city territory. Single premise
municipality come from the origin of this administrative facility: "the city house" were the mayor was living and were
all government administrative duties were performed.
Thru the centuries, the mayor has been supported by more and more complementary staff creating by purposes
respective services departments. Along this employment grow, city properties availabilities or acquisitions, services
offices started to span either across several physical building facilities within the city area either across larger
geographical area when the administrative entity span on multiple contiguous cities or villages.
Municipalities nowadays have also undertaken several other responsibilities such as safety, education, waste
management and recycling, healthcare, water and electricity distribution, public transportation and potentially many
more.
Most of today municipalities are supported by Information and Communications Technologies to help the city staff to
perform the daily work, communicate with each other and with the higher authorities. In that concern, municipalities
operations should be considered as an enterprise ranging from a Small Office Home Office (SOHO), a Small and
Medium Enterprise (SME) up to large enterprise. According to the respective type of enterprise the city can be matched
to, technical recommendations which applies to homes and offices ICT deployments such as ETSI TS 105 174-5-1 [i.4],
ETSI TS 105 174-5-2 [i.5] and ETSI TS 105 174-5-4 [i.6] or to telecommunication services providers such as ETSI
TR 105 174-2-1 [i.7] should be considered to improve the energy management of the city ICT deployment.
Indeed, from a networking perspective municipalities have various challenges to face to.

4.2 Inside-building connectivity cabling infrastructure
Regularly the buildings which host the municipal staff are not contemporary and have not been designed with IT in
mind. Furthermore, in important cities, those buildings are often classified heritage buildings and construction works
are heavily constrained.
The result is that network cabling is regularly of a concern. It is common to see physical deployments where rooms are
not correctly equipped with appropriate network access socket, that network cables are inappropriately installed, that
technical facilities such as cable patch panel are imperfectly installed or simply missing, etc. Finally, poor cross-
domains vision leads often to the installation of several independent physical network cabling setups such as:
• Network cablings for analog/digital telephony services.
• Network cablings for emergency (e.g. alarms, elevators) services.
• Network cabling for IT data networking service.
• Network cabling for IP telephony service.
• Network cabling for analog/digital video surveillance service.
• Network cabling for IP video surveillance service.
There is a clear need to unify these ICT independents infrastructures thru a common multi-services physical engineering
architecture.
Requirements, specifications and best practices for the deployment of these physical cabling infrastructures are covered
by various norms such as CENELEC EN 50173-2 [1], CENELEC EN 50173-4 [2], CENELEC EN 50174-1 [3] and
CENELEC EN 50174-2 [4].
4.3 Inter-buildings connectivity cabling infrastructure
Nowadays, in many cases municipalities facilities are spread across many buildings which may or may not be near to
each other's. Besides the constrain of classified heritage buildings, distances between facilities may be large. With that
regards and according to the capabilities, municipalities either opt to deploy their own inter-building cablings either opt
for contracting external service provider(s).
Similarly to the local cabling, poor cross-domains vision regularly leads to the installation of several independent
physical network cabling setups or to establish multiple service contracts with service providers.
There is a clear need to improve the engineering architecture which interconnects the various facilities spread across the
territory.
Requirements, specifications and best practices for the deployment of these physical cabling infrastructures are covered
by various norms such as CENELEC EN 50174-1 [3] and CENELEC EN 50174-3 [5].
4.4 Digital services availability
IP networking technology leverage numerous IT services such as data transfer, digital telephony, video surveillance,
IoT operation and monitoring, etc. IT staff availability within the municipality shall be taking into account and due to
financial constrains regularly missing (Small cities, villages) or outsourced to external services provider. The
consequence is that there is limited or missing engineering view on the deployment of the digital services. It is a
common situation where the IP data network is unfortunately fragmented into multiple independent IP networks
isolated from each other and even requiring to pass thru externals service providers for internal communications.
By example, when migrating from analog/digital telephony or video security to IP telephony or video security, lack of
technical engineering and poor global networking views often lead to mirror traditional POTS (Plain Old Telephone
Service) or situation. Municipalities often deploy independent and isolated IP networks per service and per site (even
per building) whereas technically engineered design would suggest to architecture the deployment as a single unified IP
voice or video platform leveraging a multi service network spanning across the building facilities.

The engineering of a multi-services network would also open the way to innovative IT solution such as voice and video
convergences while also enabling communication between such as:
• physical IP phones and softphone running on municipal employee's computer:
• access to IP camera video streams from authorized computer within the network.
4.5 Network access coherence
Local or inter-buildings physical networking connectivity has constrained the municipal authorities to fragment their
local IP networks into isolated networking areas. Access to the Internet, or specific national network resources, with
such engineering implies to install a dedicated physical connection to a network service provider (e.g. ISP) within each
local network. Unfortunately, it is also common to have cities where Internet connections are even physically linked to
single agent computers therefore removing the capability to share the service provider access with the agent department.
The engineering of a multi-services network would also improve the accessibility to the Internet as well as to other
specific external services (e.g. national citizen or enterprises registries) such as those provided by higher authorities of
the government.
5 General considerations about digital multiservice city
Renowned technology organizations such as the ITU-T describes the concept of the sustainable city with following
terms:
"A smart sustainable city is an innovative city that uses ICT and other means to improve quality of life, efficiency of
urban operation and services, and competitiveness, while ensuring that it meets the needs of present and future
generations with respect to economic, social and environmental aspects."
This definition has been developed based on the work carried out by FG-SSC and UNECE in Recommendation ITU-T
SG5 [i.58].
The point of view of internationally recognized analysts share a strong position that technology organizations emphasis:
the importance of a transversal approach across the various services which build the organization of a city:
"A smart city is based on intelligent exchanges of information that flow between its many different subsystems. This flow
of information is analysed and translated into citizen and enterprises services. The city will act on this information flow
to make its wider ecosystem more resource-efficient and sustainable. The information exchange is based on a smart
governance operating framework designed for cities sustainable." (Gartner, 2011)
An increasing number of everyday machines and objects are now embedded with sensors or actuators and have the
ability to communicate over the Internet. Collectively they make up the Internet of Things (IoT).
With the development of the IoT, more and more of the
