SUMMARY:
We speak to Bradford City Council’s enterprise architect and information manager, Yunus
Mayat, about the area’s new Low Range Wide Area Network.
Bradford is not normally a city much associated with ‘innovation’. To date, the region has
been more synonymous with social deprivation than forward-thinking technology (in 2015
one in four children in the region were living below the poverty line). But as enterprise
architect and information manager of IT Services atBradford City CouncilYunus Mayat
explains, technology can help transform societies, and it is exactly this sort of community
or region that stands to benefit most from developments of this sort.
At the heart of the council’s technology push is a new LoRaWAN (a Low Range Wide Area
Network). It is only the second city in the UK, after London, to roll one out. London‘s
LoRaWan established around 50 base stations in September last year and both the
Greater London Authority and Bradford City Council worked closely with digital co-
ordinator Digital Catapult on their projects. Digital Catapult is backed by government-
funded Innovate UK.
The system’s media access control (MAC) protocol allows devices to communicate with
apps over a Wide Area Network. In short, it is the backbone for an Internet of Things-
based smart city with the wider aim of driving innovations in digital health, social care and
public services.
Bradford City council last month deployed 2 LoRaWAN gateways at the ODI [Open Data
Institute] Leeds and at the Digital Health Enterprise Zone (DHEZ), with a third to be set up
in the coming weeks. Each gateway is able to support up to 20,000 connected devices
and can operate at approximately 15 km in suburban settings and 2 km in dense urban
environments.
Mayat explains how the Council is working closely with other bodies on the project,
including the Digital Catapult Centre Yorkshire, the DHEZ and the University of Bradford.
The university set up an Internet of Things lab last year and has purchased a fourth
gateway for the region.
Floods and bins
The first big project to make use of the technology uses flood sensors which feed data
back to the council every 15 seconds. Two were deployed in Bradford Beck and Shipley
four weeks ago with two more on the outskirts of Bradford in Cottingley and Saltaire.
As Mayat explained this is an approach to flood management based on a scheme that the
planning team saw being run in Amsterdam. The sensors used include flood monitors,
gully sensors, and river level monitors. He said:
Bradford has had a flooding problem for a long time. We are normally
reactive regarding flood threats. But analysis of patterns in the data will mean
we can be proactive and anticipate problems before they occur.
The idea was in a part the result of a regular hackathon set up by ODI Leeds and was one
of several ideas to have come to fruition. Another idea from the event was presented by
Bradford Beck, a community group lobbying to put sea life back into the river. The project
will include use of water purity sensors to monitor PH levels and ensure the conditions are
right for the reintroduction of wildlife.
Another Lorawan-based scheme currently on trial is the management of council bins
using sensors, the project is called Binnovation. Mayat said:
Our dust trucks regularly go out of town, but many of the bins aren’t used.
It’s a waste of time. This will allow us to see which bins are full or empty and
work out where we should remove or put additional bins. This will save time
and resources and help manage litter issues within the city.
LoraWan connected devices will help Bradford council manage transport issues too.
Proposals currently under consideration include CO2 sensors, parking sensors, road
monitoring and sound sensors.
Health
Ideas around improvement of social care or health are central to the council’s LoRaWAN
project. It is working closely with Bradford University and The DHEZ to develop these with
the aim of allowing vulnerable or elderly people to live on their own for longer. One idea
currently under consideration would see sensors placed inside the plant pots of elderly
people. If watered less frequently, they would raise an alarm, as this may indicate a
deterioration for dementia patients.
Similarly, computing researchers are collaborating with the University, the DHEZ and the
department of adult services at the local authority to develop sensors for wearable
devices that would monitor blood pressure or heartbeat.
They might also be used on doors to ensure they are shut properly or on lights or curtains
to ensure they are being used as normal. Aberrations might indicate some problem that
can be followed up by social or health workers. Similarly, the same community spaces
might be fitted with sensors to monitor carbon dioxide, or monoxide, as well as act as fire
alarms or temperature sensors.
Within the council itself sensors will soon be deployed to monitor movement of staff,
ensure sign in and out, as well as meeting room and panic-alarm sensors.
New ideas for the best use of sensors are generated during monthly workshops at which
local departments brainstorm with SMEs from the area. The departments are asked to
present problems that the SMEs must solve using IoT technology.
Mayat says:
The ICT department has a grant scheme and will give grants and prizes to
the best ideas to come out of the workshops.
One proposal to come from February’s workshop proposed using sensors to monitor
water coming into and out of people’s homes. The sensors feed data to a household and
the council regarding excessive water use or leaks. The sensors are currently being
trialled in a house in Bradford. The best ideas will be developed by social impact
technology start-ups such as Konnecktis or DataFlock.
My take
Although the Bradford LoraWan is in its infancy, the project’s potential is enormous.
Similarly, the council’s scheme to encourage innovation within its own departments as
well as its ready collaboration with bodies such as the DZEH and SMEs in the private
sector make it seen dynamic as few local authorities are. Developers interested in smart
city projects should certainly watch this space.
D’un pays à l’autre, les compteurs
communicants sont-ils les mêmes ?
Source URL: http://www.les-smartgrids.fr/innovation-et-vie-quotidienne/15032017,d-
un-pays-a-l-autre-les-compteurs-communicants-sont-ils-les-memes-,2087.html
Rédigé par Julien Jormot | Le 15 mars 2017 à 16:04
S’affichant comme l’un des piliers d’une transition énergétique réussie, les
compteurs communicants doivent permettre à tout un chacun de consommer mieux
et réduire sa facture d’électricité. Mais qu’en est-il lorsque la technologie qu’ils
utilisent est imparfaite ?
C’est le point soulevé par une récente étude hollandaise dont les auteurs affirment
avoir enregistré des dysfonctionnements sur certains compteurs qui surévalueraient
la consommation des foyers. Cette nouvelle n’a pas tardé à être reprise par les
médias français s’empressant alors de faire un rapprochement avec le compteur
Linky. Pourtant, bien qu’elles soient toutes communicantes, d’un pays à l’autre, les
technologies présentes dans ces nouveaux compteurs ne sont pas nécessairement
les mêmes…
Tout récemment, Le Figaro s’est fait l'écho d'une étude hollandaise publiée le 3 mars
dans la revue scientifique hollandaise IEEE Electromagnetic Compatibily Magazine. Selon
les chercheurs bataves, certains compteurs nouvelle génération dits « intelligents »
transféreraient des données erronées aux centrales de gestionnaires de réseaux
électriques du pays. De fait, des chercheurs de l'université de Twente (Pays-Bas) en
collaboration avec l'université d'Amsterdam des sciences appliquées ont étudié neuf
compteurs intelligents, construits entre 2004 et 2014. Cinq donnaient des résultats plus
élevés – parfois de manière significative – que la consommation réelle. Deux autres des
résultats en deçà de la réalité.
L’équipe de scientifiques explique ces décalages par l’émergence de nouvelles
technologies en matière d'éclairage domestique – par exemple les nouvelles ampoules à
basse consommation et LED – qui altèrent en effet la forme « parfaite » du courant
électrique, le rendent en conséquence plus difficilement mesurable. La technique de
mesure – appelée l'effet Hall – était donc inadaptée. Les compteurs observés « n'ont pas
suffisamment tenu compte des dispositifs de commutation modernes », explique Frank
Leferink, professeur de Compatibilité électromagnétique à l'université de Twente, dans un
article qui relate les résultats de leur étude.
Il faut noter que les compteurs « intelligents » sont censés communiquer directement la
consommation du foyer où ils sont installés, sans qu’un technicien ne doive venir
effectuer une relève sur place. Leur fiabilité est donc cruciale afin d’assurer une
facturation juste aux usagers. Or, il a été observé que dans des cas isolés, certains
compteurs envoyaient des bilans tantôt trop élevés, tantôt sous-évalués. De quoi poser
certaines questions quand on sait que 35 millions de compteurs communicants « Linky »
doivent être déployés en France d’ici à 2021. Aussi, le Figaro s’est fait écho de ces
inquiétudes, ne manquant pas de faire le parallèle avec le compteur tricolore.
Si la fiabilité du compteur Linky n'est pas directement remise en question par cette étude
qui concerne un modèle différent (et par ailleurs moins sophistiqué), le parallèle peut
laisser penser qu’une défaillance similaire pourrait se produire en France. Une crainte à
laquelle Enedis – filiale d’EDF, qui procède actuellement au déploiement des compteurs
Linky – vient répondre au travers d’un communiqué de presse. Enedis assure ainsi que le
boitier français « ne peut être associé à cette étude ». Pour la société, ce bug ne peut
affecter leurs modèles, car « les constructeurs Sagemcom, Itron, ZIV et Elster
développent des compteurs Linky qui n’utilisent pas de capteurs à effet Hall ».
Le mode de mesure de Linky est en effet différent des modèles bataves. Enedis rappelle
que « la mesure est réalisée via un « shunt » (résistance de faible valeur) pour les
compteurs monophasés et/ou un transformateur de courant pour les compteurs
triphasés ». Le groupe poursuit : « les dispositifs de commutation, telles les ampoules à
basse consommation ou LED, sont parfaitement intégrées et comptabilisées par les
compteurs ». Linky a en effet pris en compte les évolutions technologiques qui ont
perturbé le modèle des Pays-Bas. Une information confirmée indépendamment par le
Laboratoire national de métrologie et d’essais (LNE). Fausse alerte, donc.
Aujourd’hui, plus de 3 millions de compteurs Linky ont été déployés en France – et ce
depuis 2009 où un premier lot de 300 000 compteurs avait été installé en Indre-et-Loire et
à Lyon pour faire l’objet d’uneétude pratique. Or, aucune malfonction n’a été relevée.
Voici le communiqué de presse diffusé par Enedis :
COMMUNIQUE DE PRESSE
Les constructeurs de compteurs communicants de type « Linky » (Sagemcom, Itron,
Landis+Gyr, Ziv, Cahors et Elster) et l’entreprise Enedis, gestionnaire du réseau
d’électricité, s’associent pour confirmer la fiabilité métrologique des compteurs
communicants actuellement déployés sur le territoire français.
Une étude de l’université néerlandaise a récemment mis en cause l’effet Hall et l'effet
Rogowski utilisés pour le comptage des données de consommation électrique.
Le compteur français « Linky » est certifié et ne peut être associé à cette étude.
Les constructeurs Sagemcom, Itron, ZIV et Elster développent des compteurs Linky qui
n’utilisent pas de capteurs à effet Hall ou Rogowski pour l’acquisition métrologique, car ils
reposent sur une mesure réalisée via un « shunt » (résistance de faible valeur) pour les
compteurs monophasés et/ou un transformateur de courant pour les compteurs
triphasés.
Le constructeur Landis+Gyr utilise une méthode différente de mesure basée sur une
solution Embedded Coil qui garantit l’ensemble des exigences légales métrologiques
pour toutes les conditions représentatives du terrain.
En matière de fiabilité métrologique, les compteurs Linky répondent à la norme MID. Et
pour aller au-delà de cette norme, ENEDIS a imposé à chacun des constructeurs de
passer des « essais d’immunité aux perturbations conduites en mode différentiel avec une
gamme de fréquence 2-150kHz » afin de respecter la norme EN 61000-4-19. Cette norme
fait référence au rapport technique CLC/TR 50579, et permet de s’assurer que les
dispositifs de commutation, telles les ampoules à basse consommation ou LED, sont
parfaitement intégrées et comptabilisées par les compteurs.
Enfin, Le LNE* a certifié les compteurs Linky conformément à la Directive Européenne
MID et selon les normes associées, dont la norme NF EN 61000-4-19.
Plus de 3 millions de compteurs communicants ont été installés sur l’ensemble du
territoire après avoir subi des tests très poussés au sein du LNE, chez les constructeurs
mais également au sein du laboratoire d’Enedis. En plus des salariés d’Enedis, 10 000
hommes et femmes sont mobilisés au quotidien pour fabriquer, remplacer et recycler les
anciens compteurs.
Turin to become Italy’s first 5G city, aims
for total deployment by 2020

By: James Bourne
Turin will become the first city in Italy with a 5G mobile network after the municipality
signed a memorandum of understanding with Telecom Italia (TIM).
The project is expected to start its metropolitan trial in 2018, with the aim of covering the
whole city by 2020. The telco will install more than 100 small cells in the main areas of the
city, as well as at both the city’s universities, with 3,000 users being made part of the trial
process.
While plenty of the industry discussion around 5G has been that of bluff and bluster – it
was the second most frequently cited term at MWC behind the Internet of Things – more
concrete plans are starting to emerge in terms of a ‘pan-European’ network of 5G-
connected cities. Bristol threw its hat into the ring bidding to become the first UK city to
test 5G last month, while Amsterdam, one of 13 cities hosting the European Football
Championship in 2020, hopes to use the network to transmit high quality video streams at
the tournament.
“The project is expected to start its metropolitan trial in 2018, with the aim of covering the
whole city by 2020. The telco will install more than 100 small cells in the main areas of the
city, as well as at both the city’s universities, with 3,000 users being made part of the trial
process.”
The International Telecommunications Union (ITU) published a draft last month over what
it believed would be the final 5G specification. To fit the bill, networks needed to hit a
minimum requirement of 20 Gbit/s for downlink peak data rate and 10 Gbit/s for uplink.
As this publication reportedat the time, the benchmarks were “ambitious but could be
achievable.”
TIM added that this deal reinforced its ‘commitment to mobile innovation’ as well as
‘contributing to the definition of the 5G standard’.
“When we talk about big data, digital identity and the Internet of Things, we are aware that
underlying all this there is always quality and the speed of the networks,” said Giuseppe
Recchi, TIM executive chairman. “TIM has the privilege of being a leading company in the
development of the digital culture of the country and today this agreement adds another
important element to our strategy.”
“It is a positive sign that TIM has chosen Turin as an urban area to test an innovative
technology such as 5G, linked to the mobile network,” said Chiara Appendino, mayor of
Turin in a statement. “The high speed services and applications can only bring benefit, in
the immediate future, to the manufacturing world and the community.”
Going further down the line, the proposal will also take into accountsmart cityplans, from
managing public transport fleets, to remote surveillance and virtual reality for tourism, as
well asIndustry 4.0initiatives.
Roberto Minerva, chairman of the Internet of Things initiative at IEEE, cites Venice as an
example of an Italian city which was ‘challenging’ to get off the ground as a smart city. He
told this reporter at the end of last year that cities do not have one single model for
‘smartness’, and that the cultural and social perspectives were key. “It should be a
combination of the technology, and the ability of the technology to capture a large number
of data in that specific environment,” he said.
According to the GSMA, commercial 5G networks will be ‘widely deployed’ by the
beginning of the next decade, with connections to hit 1.1 billion globally by 2025.

Schneider Electric targets IoT and edge
apps with micro data centre

edge-apps-micro-data-centre/
Hannah Williams - Reporter 15th March 2017
Schneider Electric develops the micro data centre with IoT, edge & cooling products.
Schneider Electric has introduced its Micro Data Centre (DC) Xpress line of connected
products, for what it is calling a faster, easier and more effective way to build and deploy
micro data centres at the network edge.
Micro DC Xpress is available in 24U and 42U, as well as customisable configurations,
which have been testes in the company’s factories to ensure reliability.
Also using Schneider Electric’s Data Centre Infrastructure Management (DCIM) software
suite, StruxureWare for Data Centres, is built on its EcoStruxure integrated architecture
platform. The service can be integrated into a customer’s larger IT-asset monitoring
system or a managed service provider’s RMM and remotely managed via the cloud for
maximum uptime and connectivity.
Chris Hanley, SVP, Data Centre Systems, Schneider Electric said: “In our digitally-
connected world, businesses and consumers have a low threshold for interruptions to
service.
“Edge computing solves real-time data transmission issues by bringing bandwidth-
intensive content and latency-sensitive applications close to the users or data sources to
ensure reliable connectivity.”
It is designed to enable customers to pre-install IT equipment before shipment, and
comes with complete data centre physical infrastructure and management software in a
single self-contained and secure enclosure.
In addition to this, Schneider Electric also delivered its new Ecoflair Indirect Air
Economizer cooling solution, a new system that is able to reduce operating costs by over
60 percent.
The new system uses a proprietary polymer heat exchanger technology, which provides a
cost-effective and highly energy efficient approach to data centre cooling.
Ecoflair is available in 250kW and 500kW modules and is designed to offer flexible and
greater customisation, based on the cooling requirement and local condition, simplified
installation and associated expenses. This also includes increased serviceability together
with lowered maintenance costs.
The rate of the reduced costs enables a greater proportion of data centre energy to be
available for powering IT equipment and improving facility Power Usage Effectiveness
(PUE).
By being able to reduce cooling costs by a large amount compared with legacy systems
based on chilled water or refrigerant technologies, the overall efficiency of Ecoflair has
been found to be better than other by between 15 and 20 percent.
This increased efficiency provides customers with options for energy savings such as,
increasing the IT load with the same electrical infrastructure and reduction in the overall
CAPEX due to a smaller electrical infrastructure needed from a smaller electrical
distribution and back-up power requirements.
Its scalable approach is said to make the Ecoflair system to be particularly suited for
colocation facilities between one and 5MW (250kW modules) and large hyperscale or
cloud data centres rated up to 40MW (500kW modules).
This is developed in order to help data centre owners standardise the cooling architecture
of their facilities around the world, with provided designs which speed the deployment
and reduce operational and maintenance costs.
The Micro DC Xpress will be available to order in UK, North America and France in April
2017 and to be deployed across Europe later in the year.
Big data lab to boost digital economy
Source URL: http://www.chinadaily.com.cn/business/2017-
03/14/content_28543800.htm
By Ouyang Shijia | China Daily | Updated: 2017-03-14 08:51
China launched its first national engineering laboratory for big data distribution and
exchange technologies on Saturday.
The move is seen boosting the country's digital economy and helping build its strengths
to compete in the global market.
Yang Shanlin, director of the lab and an academician at the Chinese Academy of
Engineering, said the lab will seek breakthroughs in the research and application of big
data.
It will also help the government better regulate the exchange and distribution process.
"We will actively conduct research in the fundamental theories of big data, including data
collection, open data and data security. In terms of applying big data to industries, we will
build innovation centers and conduct research in key technologies for industries like
finance, media, advanced manufacturing, energy, healthcare and education."
He also said the lab will research policy, to help set quality and service standards in big
data.
The lab was approved by the National Development and Reform Commission, China's top
economic planner, in February.
The lab will be led by Shanghai Data Exchange Corp. Other backers include China
Internet Network Information Center, China United Network Communications Group Co,
Fudan University, the China Academy of Information and Communications Technology,
and Inspur Group Co Ltd.
"We will work closely with our partners to promote research into key technologies and
applications of big data in different fields," said Tang Qifeng, CEO of Shanghai Data
Exchange Corp.
According to Tang, 13 research centers have been set up to conduct related research.
The centers would be led by different enterprises, institutions and universities.
Tang said about one-third of the investment came from the NDRC, and the rest was
contributed by Shanghai Data Exchange Corp and its partners.
With more than 700 million internet users and over 1.3 billion mobile phone users, China
is among the largest data producers on the globe, and is entering a period of rapid
development of information and technology industries.
From 2010 to 2015, China has doubled its sales in the information industry, hitting 17.1
trillion yuan ($2.47 trillion), according to a government plan unveiled in January.
Project Sunroof Now Predicting Rooftop
Solar Potential In All 50 US States
Source URL: https://cleantechnica.com/2017/03/16/project-sunroof-now-predicting-
rooftop-solar-potential-50-us-states/
March 16th, 2017 by Joshua S Hill
Google’s has announced that its revolutionary Project Sunroof tool is now able to provide
a reliable estimate of how much sunlight a given rooftop might receive in all 50 US states,
up from 42 states nearly a year ago.
The last we heard from Project Sunroof, it was revealed that it had been expanded to
provide data to 42 states across the US, up from 10 states only a few months earlier.
Project Sunroof started as one of Google’s 20% projects — projects Google employees
can work on in 20% of their time at Google, which sometimes then get branded as a
Google product with the company’s full backing. Project Sunroof uses imagery from
Google Maps and Google EARTH, 3D modelling, and machine learning to estimate how
much sunlight a given rooftop receives, helping to answer how much energy a given
rooftop could produce if it had solar panels.
Visualization of solar potential at the Googleplex in Mountain View, CA.
Google announced on its The Keyword blog this week that Project Sunroof is now
providing data for all 50 US states, and according to Joel Conkling, product manager, the
expanded data has shed some light (get it?) on some interesting insights about the
potential US solar industry:
79% of all rooftops analyzed are technically viable for solar, meaning those rooftops
have enough unshaded area for solar panels.
Over 90% of homes in Hawaii, Arizona, Nevada, and New Mexico are technically
viable, while states like Pennsylvania, Maine and Minnesota reach just above 60%
viability.
Houston, TX, has the most solar potential of any US city in the Project Sunroof
data, with an estimated 18,940 gigawatt-hours (GWh) of rooftop solar generation
potential per year. Los Angeles, Phoenix, San Antonio, and New York follow
Houston for the top 5 solar potential cities — see the full top 10 list in the chart
below.
“If the top ten cities above reached their full rooftop solar potential, they’d produce
enough energy to power 8 million homes across the US,” Conkling said.

Revue de presse IoT / Data du 19/03/2017

  • 1. Revue de presse IoT / Data du 19/03/2017 Bonjour, Voici la revue de presse IoT/data/energie du 19 mars 2017. Cette semaine, Google étend son projet de détection des potentiels toits solaires (à tester !), plusieurs villes qui ne sont pas des hubs de l’innovation se lancent dans des initiatives de smartcity et de 5G. La data des réseaux subit des évolutions dans différents points de vues, d’une fabrication qui met en doute au compteur communicant à l’exploitation (en Chine) en passant par les datacenter Schneider pour traiter les données au plus proche du lieu de leur production. Bonne lecture et à la semaine prochaine ! Sommaire : 1. Bradford City Council, the Internet-of-Things and better public service 2. D’un pays à l’autre, les compteurs communicants sont-ils les mêmes ? 3. Turin to become Italy’s first 5G city, aims for total deployment by 2020 4. Schneider Electric targets IoT and edge apps with micro data centre 5. Big data lab to boost digital economy 6. Project Sunroof Now Predicting Rooftop Solar Potential In All 50 US States Bradford City Council, the Internet-of- Things and better public service Source URL: http://diginomica.com/2017/03/16/bradford-city-council-internet-things- better-public-service/ SUMMARY: We speak to Bradford City Council’s enterprise architect and information manager, Yunus Mayat, about the area’s new Low Range Wide Area Network. Bradford is not normally a city much associated with ‘innovation’. To date, the region has been more synonymous with social deprivation than forward-thinking technology (in 2015 one in four children in the region were living below the poverty line). But as enterprise architect and information manager of IT Services atBradford City CouncilYunus Mayat explains, technology can help transform societies, and it is exactly this sort of community or region that stands to benefit most from developments of this sort. At the heart of the council’s technology push is a new LoRaWAN (a Low Range Wide Area Network). It is only the second city in the UK, after London, to roll one out. London‘s LoRaWan established around 50 base stations in September last year and both the Greater London Authority and Bradford City Council worked closely with digital co-
  • 2. ordinator Digital Catapult on their projects. Digital Catapult is backed by government- funded Innovate UK. The system’s media access control (MAC) protocol allows devices to communicate with apps over a Wide Area Network. In short, it is the backbone for an Internet of Things- based smart city with the wider aim of driving innovations in digital health, social care and public services. Bradford City council last month deployed 2 LoRaWAN gateways at the ODI [Open Data Institute] Leeds and at the Digital Health Enterprise Zone (DHEZ), with a third to be set up in the coming weeks. Each gateway is able to support up to 20,000 connected devices and can operate at approximately 15 km in suburban settings and 2 km in dense urban environments. Mayat explains how the Council is working closely with other bodies on the project, including the Digital Catapult Centre Yorkshire, the DHEZ and the University of Bradford. The university set up an Internet of Things lab last year and has purchased a fourth gateway for the region. Floods and bins The first big project to make use of the technology uses flood sensors which feed data back to the council every 15 seconds. Two were deployed in Bradford Beck and Shipley four weeks ago with two more on the outskirts of Bradford in Cottingley and Saltaire. As Mayat explained this is an approach to flood management based on a scheme that the planning team saw being run in Amsterdam. The sensors used include flood monitors, gully sensors, and river level monitors. He said: Bradford has had a flooding problem for a long time. We are normally reactive regarding flood threats. But analysis of patterns in the data will mean we can be proactive and anticipate problems before they occur. The idea was in a part the result of a regular hackathon set up by ODI Leeds and was one of several ideas to have come to fruition. Another idea from the event was presented by Bradford Beck, a community group lobbying to put sea life back into the river. The project will include use of water purity sensors to monitor PH levels and ensure the conditions are right for the reintroduction of wildlife. Another Lorawan-based scheme currently on trial is the management of council bins using sensors, the project is called Binnovation. Mayat said: Our dust trucks regularly go out of town, but many of the bins aren’t used. It’s a waste of time. This will allow us to see which bins are full or empty and work out where we should remove or put additional bins. This will save time and resources and help manage litter issues within the city. LoraWan connected devices will help Bradford council manage transport issues too. Proposals currently under consideration include CO2 sensors, parking sensors, road monitoring and sound sensors.
  • 3. Health Ideas around improvement of social care or health are central to the council’s LoRaWAN project. It is working closely with Bradford University and The DHEZ to develop these with the aim of allowing vulnerable or elderly people to live on their own for longer. One idea currently under consideration would see sensors placed inside the plant pots of elderly people. If watered less frequently, they would raise an alarm, as this may indicate a deterioration for dementia patients. Similarly, computing researchers are collaborating with the University, the DHEZ and the department of adult services at the local authority to develop sensors for wearable devices that would monitor blood pressure or heartbeat. They might also be used on doors to ensure they are shut properly or on lights or curtains to ensure they are being used as normal. Aberrations might indicate some problem that can be followed up by social or health workers. Similarly, the same community spaces might be fitted with sensors to monitor carbon dioxide, or monoxide, as well as act as fire alarms or temperature sensors. Within the council itself sensors will soon be deployed to monitor movement of staff, ensure sign in and out, as well as meeting room and panic-alarm sensors. New ideas for the best use of sensors are generated during monthly workshops at which local departments brainstorm with SMEs from the area. The departments are asked to present problems that the SMEs must solve using IoT technology. Mayat says: The ICT department has a grant scheme and will give grants and prizes to the best ideas to come out of the workshops. One proposal to come from February’s workshop proposed using sensors to monitor water coming into and out of people’s homes. The sensors feed data to a household and the council regarding excessive water use or leaks. The sensors are currently being trialled in a house in Bradford. The best ideas will be developed by social impact technology start-ups such as Konnecktis or DataFlock. My take Although the Bradford LoraWan is in its infancy, the project’s potential is enormous. Similarly, the council’s scheme to encourage innovation within its own departments as well as its ready collaboration with bodies such as the DZEH and SMEs in the private sector make it seen dynamic as few local authorities are. Developers interested in smart city projects should certainly watch this space. D’un pays à l’autre, les compteurs
  • 4. communicants sont-ils les mêmes ? Source URL: http://www.les-smartgrids.fr/innovation-et-vie-quotidienne/15032017,d- un-pays-a-l-autre-les-compteurs-communicants-sont-ils-les-memes-,2087.html Rédigé par Julien Jormot | Le 15 mars 2017 à 16:04 S’affichant comme l’un des piliers d’une transition énergétique réussie, les compteurs communicants doivent permettre à tout un chacun de consommer mieux et réduire sa facture d’électricité. Mais qu’en est-il lorsque la technologie qu’ils utilisent est imparfaite ? C’est le point soulevé par une récente étude hollandaise dont les auteurs affirment avoir enregistré des dysfonctionnements sur certains compteurs qui surévalueraient la consommation des foyers. Cette nouvelle n’a pas tardé à être reprise par les médias français s’empressant alors de faire un rapprochement avec le compteur Linky. Pourtant, bien qu’elles soient toutes communicantes, d’un pays à l’autre, les technologies présentes dans ces nouveaux compteurs ne sont pas nécessairement les mêmes… Tout récemment, Le Figaro s’est fait l'écho d'une étude hollandaise publiée le 3 mars dans la revue scientifique hollandaise IEEE Electromagnetic Compatibily Magazine. Selon les chercheurs bataves, certains compteurs nouvelle génération dits « intelligents » transféreraient des données erronées aux centrales de gestionnaires de réseaux électriques du pays. De fait, des chercheurs de l'université de Twente (Pays-Bas) en collaboration avec l'université d'Amsterdam des sciences appliquées ont étudié neuf compteurs intelligents, construits entre 2004 et 2014. Cinq donnaient des résultats plus élevés – parfois de manière significative – que la consommation réelle. Deux autres des résultats en deçà de la réalité. L’équipe de scientifiques explique ces décalages par l’émergence de nouvelles technologies en matière d'éclairage domestique – par exemple les nouvelles ampoules à basse consommation et LED – qui altèrent en effet la forme « parfaite » du courant électrique, le rendent en conséquence plus difficilement mesurable. La technique de mesure – appelée l'effet Hall – était donc inadaptée. Les compteurs observés « n'ont pas suffisamment tenu compte des dispositifs de commutation modernes », explique Frank Leferink, professeur de Compatibilité électromagnétique à l'université de Twente, dans un article qui relate les résultats de leur étude. Il faut noter que les compteurs « intelligents » sont censés communiquer directement la consommation du foyer où ils sont installés, sans qu’un technicien ne doive venir effectuer une relève sur place. Leur fiabilité est donc cruciale afin d’assurer une facturation juste aux usagers. Or, il a été observé que dans des cas isolés, certains compteurs envoyaient des bilans tantôt trop élevés, tantôt sous-évalués. De quoi poser certaines questions quand on sait que 35 millions de compteurs communicants « Linky » doivent être déployés en France d’ici à 2021. Aussi, le Figaro s’est fait écho de ces inquiétudes, ne manquant pas de faire le parallèle avec le compteur tricolore. Si la fiabilité du compteur Linky n'est pas directement remise en question par cette étude qui concerne un modèle différent (et par ailleurs moins sophistiqué), le parallèle peut laisser penser qu’une défaillance similaire pourrait se produire en France. Une crainte à
  • 5. laquelle Enedis – filiale d’EDF, qui procède actuellement au déploiement des compteurs Linky – vient répondre au travers d’un communiqué de presse. Enedis assure ainsi que le boitier français « ne peut être associé à cette étude ». Pour la société, ce bug ne peut affecter leurs modèles, car « les constructeurs Sagemcom, Itron, ZIV et Elster développent des compteurs Linky qui n’utilisent pas de capteurs à effet Hall ». Le mode de mesure de Linky est en effet différent des modèles bataves. Enedis rappelle que « la mesure est réalisée via un « shunt » (résistance de faible valeur) pour les compteurs monophasés et/ou un transformateur de courant pour les compteurs triphasés ». Le groupe poursuit : « les dispositifs de commutation, telles les ampoules à basse consommation ou LED, sont parfaitement intégrées et comptabilisées par les compteurs ». Linky a en effet pris en compte les évolutions technologiques qui ont perturbé le modèle des Pays-Bas. Une information confirmée indépendamment par le Laboratoire national de métrologie et d’essais (LNE). Fausse alerte, donc. Aujourd’hui, plus de 3 millions de compteurs Linky ont été déployés en France – et ce depuis 2009 où un premier lot de 300 000 compteurs avait été installé en Indre-et-Loire et à Lyon pour faire l’objet d’uneétude pratique. Or, aucune malfonction n’a été relevée. Voici le communiqué de presse diffusé par Enedis : COMMUNIQUE DE PRESSE Les constructeurs de compteurs communicants de type « Linky » (Sagemcom, Itron, Landis+Gyr, Ziv, Cahors et Elster) et l’entreprise Enedis, gestionnaire du réseau d’électricité, s’associent pour confirmer la fiabilité métrologique des compteurs communicants actuellement déployés sur le territoire français. Une étude de l’université néerlandaise a récemment mis en cause l’effet Hall et l'effet Rogowski utilisés pour le comptage des données de consommation électrique. Le compteur français « Linky » est certifié et ne peut être associé à cette étude. Les constructeurs Sagemcom, Itron, ZIV et Elster développent des compteurs Linky qui n’utilisent pas de capteurs à effet Hall ou Rogowski pour l’acquisition métrologique, car ils reposent sur une mesure réalisée via un « shunt » (résistance de faible valeur) pour les compteurs monophasés et/ou un transformateur de courant pour les compteurs triphasés. Le constructeur Landis+Gyr utilise une méthode différente de mesure basée sur une solution Embedded Coil qui garantit l’ensemble des exigences légales métrologiques pour toutes les conditions représentatives du terrain. En matière de fiabilité métrologique, les compteurs Linky répondent à la norme MID. Et pour aller au-delà de cette norme, ENEDIS a imposé à chacun des constructeurs de passer des « essais d’immunité aux perturbations conduites en mode différentiel avec une gamme de fréquence 2-150kHz » afin de respecter la norme EN 61000-4-19. Cette norme fait référence au rapport technique CLC/TR 50579, et permet de s’assurer que les dispositifs de commutation, telles les ampoules à basse consommation ou LED, sont parfaitement intégrées et comptabilisées par les compteurs.
  • 6. Enfin, Le LNE* a certifié les compteurs Linky conformément à la Directive Européenne MID et selon les normes associées, dont la norme NF EN 61000-4-19. Plus de 3 millions de compteurs communicants ont été installés sur l’ensemble du territoire après avoir subi des tests très poussés au sein du LNE, chez les constructeurs mais également au sein du laboratoire d’Enedis. En plus des salariés d’Enedis, 10 000 hommes et femmes sont mobilisés au quotidien pour fabriquer, remplacer et recycler les anciens compteurs. Turin to become Italy’s first 5G city, aims for total deployment by 2020 Source URL: https://www.iottechexpo.com/2017/03/smart-cities/turin-become-italys- first-5g-city-aims-total-deployment-2020/ By: James Bourne Turin will become the first city in Italy with a 5G mobile network after the municipality signed a memorandum of understanding with Telecom Italia (TIM). The project is expected to start its metropolitan trial in 2018, with the aim of covering the whole city by 2020. The telco will install more than 100 small cells in the main areas of the city, as well as at both the city’s universities, with 3,000 users being made part of the trial process. While plenty of the industry discussion around 5G has been that of bluff and bluster – it was the second most frequently cited term at MWC behind the Internet of Things – more concrete plans are starting to emerge in terms of a ‘pan-European’ network of 5G- connected cities. Bristol threw its hat into the ring bidding to become the first UK city to test 5G last month, while Amsterdam, one of 13 cities hosting the European Football Championship in 2020, hopes to use the network to transmit high quality video streams at the tournament. “The project is expected to start its metropolitan trial in 2018, with the aim of covering the whole city by 2020. The telco will install more than 100 small cells in the main areas of the city, as well as at both the city’s universities, with 3,000 users being made part of the trial process.” The International Telecommunications Union (ITU) published a draft last month over what
  • 7. it believed would be the final 5G specification. To fit the bill, networks needed to hit a minimum requirement of 20 Gbit/s for downlink peak data rate and 10 Gbit/s for uplink. As this publication reportedat the time, the benchmarks were “ambitious but could be achievable.” TIM added that this deal reinforced its ‘commitment to mobile innovation’ as well as ‘contributing to the definition of the 5G standard’. “When we talk about big data, digital identity and the Internet of Things, we are aware that underlying all this there is always quality and the speed of the networks,” said Giuseppe Recchi, TIM executive chairman. “TIM has the privilege of being a leading company in the development of the digital culture of the country and today this agreement adds another important element to our strategy.” “It is a positive sign that TIM has chosen Turin as an urban area to test an innovative technology such as 5G, linked to the mobile network,” said Chiara Appendino, mayor of Turin in a statement. “The high speed services and applications can only bring benefit, in the immediate future, to the manufacturing world and the community.” Going further down the line, the proposal will also take into accountsmart cityplans, from managing public transport fleets, to remote surveillance and virtual reality for tourism, as well asIndustry 4.0initiatives. Roberto Minerva, chairman of the Internet of Things initiative at IEEE, cites Venice as an example of an Italian city which was ‘challenging’ to get off the ground as a smart city. He told this reporter at the end of last year that cities do not have one single model for ‘smartness’, and that the cultural and social perspectives were key. “It should be a combination of the technology, and the ability of the technology to capture a large number of data in that specific environment,” he said. According to the GSMA, commercial 5G networks will be ‘widely deployed’ by the beginning of the next decade, with connections to hit 1.1 billion globally by 2025. Originally published on Telecoms Tech. Schneider Electric targets IoT and edge apps with micro data centre Source URL: http://www.cbronline.com/news/data-centre/schneider-electric-targets-iot- edge-apps-micro-data-centre/ Hannah Williams - Reporter 15th March 2017 Schneider Electric develops the micro data centre with IoT, edge & cooling products. Schneider Electric has introduced its Micro Data Centre (DC) Xpress line of connected products, for what it is calling a faster, easier and more effective way to build and deploy micro data centres at the network edge.
  • 8. Micro DC Xpress is available in 24U and 42U, as well as customisable configurations, which have been testes in the company’s factories to ensure reliability. Also using Schneider Electric’s Data Centre Infrastructure Management (DCIM) software suite, StruxureWare for Data Centres, is built on its EcoStruxure integrated architecture platform. The service can be integrated into a customer’s larger IT-asset monitoring system or a managed service provider’s RMM and remotely managed via the cloud for maximum uptime and connectivity. Chris Hanley, SVP, Data Centre Systems, Schneider Electric said: “In our digitally- connected world, businesses and consumers have a low threshold for interruptions to service. “Edge computing solves real-time data transmission issues by bringing bandwidth- intensive content and latency-sensitive applications close to the users or data sources to ensure reliable connectivity.” It is designed to enable customers to pre-install IT equipment before shipment, and comes with complete data centre physical infrastructure and management software in a single self-contained and secure enclosure. In addition to this, Schneider Electric also delivered its new Ecoflair Indirect Air Economizer cooling solution, a new system that is able to reduce operating costs by over 60 percent. The new system uses a proprietary polymer heat exchanger technology, which provides a cost-effective and highly energy efficient approach to data centre cooling. Ecoflair is available in 250kW and 500kW modules and is designed to offer flexible and greater customisation, based on the cooling requirement and local condition, simplified installation and associated expenses. This also includes increased serviceability together with lowered maintenance costs. The rate of the reduced costs enables a greater proportion of data centre energy to be available for powering IT equipment and improving facility Power Usage Effectiveness (PUE). By being able to reduce cooling costs by a large amount compared with legacy systems based on chilled water or refrigerant technologies, the overall efficiency of Ecoflair has been found to be better than other by between 15 and 20 percent. This increased efficiency provides customers with options for energy savings such as, increasing the IT load with the same electrical infrastructure and reduction in the overall CAPEX due to a smaller electrical infrastructure needed from a smaller electrical distribution and back-up power requirements. Its scalable approach is said to make the Ecoflair system to be particularly suited for colocation facilities between one and 5MW (250kW modules) and large hyperscale or cloud data centres rated up to 40MW (500kW modules). This is developed in order to help data centre owners standardise the cooling architecture

The Micro DC Xpress will be available to order in UK, North America and France in April 2017 and to be deployed across Europe later in the year. Big data lab to boost digital economy Source URL: http://www.chinadaily.com.cn/business/2017- 03/14/content_28543800.htm By Ouyang Shijia | China Daily | Updated: 2017-03-14 08:51 China launched its first national engineering laboratory for big data distribution and exchange technologies on Saturday. The move is seen boosting the country's digital economy and helping build its strengths to compete in the global market. Yang Shanlin, director of the lab and an academician at the Chinese Academy of Engineering, said the lab will seek breakthroughs in the research and application of big data. It will also help the government better regulate the exchange and distribution process. "We will actively conduct research in the fundamental theories of big data, including data collection, open data and data security. In terms of applying big data to industries, we will build innovation centers and conduct research in key technologies for industries like finance, media, advanced manufacturing, energy, healthcare and education." He also said the lab will research policy, to help set quality and service standards in big data. The lab was approved by the National Development and Reform Commission, China's top economic planner, in February. The lab will be led by Shanghai Data Exchange Corp. Other backers include China Internet Network Information Center, China United Network Communications Group Co, Fudan University, the China Academy of Information and Communications Technology, and Inspur Group Co Ltd. "We will work closely with our partners to promote research into key technologies and applications of big data in different fields," said Tang Qifeng, CEO of Shanghai Data Exchange Corp. According to Tang, 13 research centers have been set up to conduct related research. The centers would be led by different enterprises, institutions and universities. Tang said about one-third of the investment came from the NDRC, and the rest was contributed by Shanghai Data Exchange Corp and its partners.

With more than 700 million internet users and over 1.3 billion mobile phone users, China is among the largest data producers on the globe, and is entering a period of rapid development of information and technology industries. From 2010 to 2015, China has doubled its sales in the information industry, hitting 17.1 trillion yuan ($2.47 trillion), according to a government plan unveiled in January. Project Sunroof Now Predicting Rooftop Solar Potential In All 50 US States Source URL: https://cleantechnica.com/2017/03/16/project-sunroof-now-predicting- rooftop-solar-potential-50-us-states/ March 16th, 2017 by Joshua S Hill Google’s has announced that its revolutionary Project Sunroof tool is now able to provide a reliable estimate of how much sunlight a given rooftop might receive in all 50 US states, up from 42 states nearly a year ago. The last we heard from Project Sunroof, it was revealed that it had been expanded to provide data to 42 states across the US, up from 10 states only a few months earlier. Project Sunroof started as one of Google’s 20% projects — projects Google employees can work on in 20% of their time at Google, which sometimes then get branded as a Google product with the company’s full backing. Project Sunroof uses imagery from Google Maps and Google EARTH, 3D modelling, and machine learning to estimate how much sunlight a given rooftop receives, helping to answer how much energy a given rooftop could produce if it had solar panels.

  • 11. Google announced on its The Keyword blog this week that Project Sunroof is now providing data for all 50 US states, and according to Joel Conkling, product manager, the expanded data has shed some light (get it?) on some interesting insights about the potential US solar industry: 79% of all rooftops analyzed are technically viable for solar, meaning those rooftops have enough unshaded area for solar panels. Over 90% of homes in Hawaii, Arizona, Nevada, and New Mexico are technically viable, while states like Pennsylvania, Maine and Minnesota reach just above 60% viability. Houston, TX, has the most solar potential of any US city in the Project Sunroof data, with an estimated 18,940 gigawatt-hours (GWh) of rooftop solar generation potential per year. Los Angeles, Phoenix, San Antonio, and New York follow Houston for the top 5 solar potential cities — see the full top 10 list in the chart below. “If the top ten cities above reached their full rooftop solar potential, they’d produce enough energy to power 8 million homes across the US,” Conkling said.
