made, i.e. the right resources are not allocated
to the most valuable areas for the sake of
greater efficiency in the others. To be clearer,
I had experience of some projects where, for
example, remote management and Smart City
devices were provided everywhere in all areas,
when it would be more correct to foresee a
share of these investments for all projects only
in the most prestigious areas.
A truly intelligent lighting, based on real-time
measurement sensors, is by definition
a lighting that is able to immediately redefine
the ways in which it relates to the surrounding
environment, depending on the environmental
conditions. Unlike the lighting based on pre-set
adjustment times, which is by its nature rigid and
invariant to the needs of the connected city, the
intelligent lighting can determine connectivity
gradients between different areas.

best scenario for that context and at that
particular time. In this case, we speak of a real
"City Automation".
The possibility of exploiting the Cloud allows
the different areas to interact in a synergistic
way, creating a real "city neural network" that
reacts in real-time, just like in the human body.
The city speaks and communicates its needs to
the Cloud through technology combined with
street lights, reducing the light when it is not
needed in an adaptive way, through targeted
and careful dimming, depending on traffic and/or
weather conditions – in compliance, for instance,
with the UNI 11248 regulation, which considers
both TAI (traffic adaptive installation) and FAI
(full adaptive installation) –, or by increasing the
light when needed, for example at a pedestrian
crossing. In short, a "neural" and neuralgic
network that exploits the pervasiveness of public
lighting and existing networks by equipping it
with IoT technology, to improve the quality of life
of cities and citizens by increasing the degree
of service offered at the same time.

The technology we have developed
addresses the issue of the urban landscape
and light pollution in relation to what happens
in the city. Thanks to UNI 11248, it is possible
to control and limit lighting, while fully
respecting environmental safety. These
parameters remain unchanged even by lowering
illuminance levels to contain the effects of light
pollution. The TAI (traffic adaptive installation)
and FAI (full adaptive installation) protocols
are useful for managing vehicle traffic and the
different weather conditions that may occur.

The differences should be addressed in the
design stage: a good professional and a
quality project can perform well at this end
and, thanks to LEDs, much better than in the
past. Everything is then filtered, and sometimes
distorted, according to the available resources.
Unfortunately, sometimes you see "non-
projects", or situations in which choices are not

Greatly. The results coming from the many
systems in operation and managed by
real-time sensors (adaptive lighting) show that
the reduction of CO 2 emissions and light pollution
can reach more than 50% compared to a
"non-intelligent system". From this point of view,
the investment in intelligent lighting not only
pays for itself in a few years, but it also has
enormous value for safeguarding the
environment. These data have been proven
thanks to the LIFE DIADEME project, funded by the
European Union, which has seen the installation,
in Rome EUR, of a thousand devices capable of
achieving adaptive and more sustainable lighting,
as well as allowing a detailed monitoring
of noise, traffic, and air quality.

or celebrations. However, it also becomes a tool
for urban renewal in poor quality areas: in the
suburbs, as well as in less-valued areas, lighting
plays a central role, first and foremost capable of
restoring safety and space to the citizens, but
that is not all. Areas become meeting places,
sites where events may be held, where a new
agorà will be created, often even in neglected
areas, where opportunities for the city and
citizens can really arise.
A Smart City is also an "interconnected" city.
And how can a city, the sum of multiple
urban fabrics, multiple areas, even located in
marginal areas, become interconnected? Also
having to guarantee safety, and above all
sustainability? There are several solutions that can
be adopted, but the Public Lighting infrastructure
certainly offers an affordable and low-cost
solution. The City must become interconnected
and interactive with the citizens to whom it must
offer services. Thanks to the capillarity of the
Public Lighting network and UVAX technology, the
network becomes a large Metropolitan Area
Network (MAN), with a Data Transfer Rate of over 1
Gb/s. Thanks to this transmission capacity, we are
able to interconnect the city buildings and the
entire municipal area, furthermore allowing

Historically, lighting has always been one of
the key elements that have distinguished the
level of enhancement of the cities. The main areas
of the city of Byzantium, which in 600 A.D. was
the renowned capital of the Eastern Roman
Empire, were fully illuminated, while the large
cities of Longobard Italy (Cividale, Aquileia
Concordia, etc.) were mostly left in the dark or to
the free initiative of the citizens. The very safety of
the cities was determined by the lighting; poorly
lit areas were often no man's land where
personal safety was far from guaranteed. The
border areas, where light was not yet ruling out
the shadow, were extremely dangerous territories.
Over the years, urban lighting, thanks also to
technological advancement, began to play an
increasingly active role in city life; today, it
represents an indispensable element in the urban
economy. Thanks to LEDs and control systems, the
historic centres have acquired a new centrality, as
light has become a form of art capable of
enhancing and emphasizing the artistic beauties
of the city. However, we can no longer define it as
a static beauty: it has become a dynamic beauty
that evolves, follows seasons and events.
By virtue of technology, light becomes an
aggregation tool for cities on important occasions
1
Public Administrations to have their own
communication infrastructure: the city becomes
interconnected. Lighting is intelligent and
futuristic, and ready for a further quantum leap,
the Li-Fi, which will increasingly make lighting
become the main data carrier.
Lighting, with the help of technology, has
become an architectural element of
enhancement of urban areas and even more often
of suburban ones, where multiple needs must be
met: safety, enhancement of the landscape,
reduction and limitation of light pollution.
Technology has become a key element in
ensuring that these needs are best served.
Lighting, thanks to the Uvax technology and the
LEDs, becomes a dynamic tool, which allows to
reach a high level of flexibility in all conditions,
restoring the right features to the landscape,
without losing the focus on safety, and
significantly reducing light pollution. All of this
can be achieved thanks to the Uvax technology,
which exploits PLC communication in
broadband: the system, which can be created
without additional wiring, allows to reach very
high data rates, therefore offering real-time
services, proving to be resistant to interference
and, lastly, offering unlimited security.
