Bradford City Council, the Internet-of-Things and better public serviceSource 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, YunusMayat, about the area’s new Low Range Wide Area Network.

Bradford is not normally a city much associated with ‘innovation’. To date, the region hasbeen more synonymous with social deprivation than forward-thinking technology (in 2015one in four children in the region were living below the poverty line). But as enterprisearchitect and information manager of IT Services atBradford City CouncilYunus Mayatexplains, technology can help transform societies, and it is exactly this sort of communityor 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 AreaNetwork). It is only the second city in the UK, after London, to roll one out. London‘sLoRaWan established around 50 base stations in September last year and both theGreater 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 withapps 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 andpublic services.

Bradford City council last month deployed 2 LoRaWAN gateways at the ODI [Open DataInstitute] Leeds and at the Digital Health Enterprise Zone (DHEZ), with a third to be set upin the coming weeks. Each gateway is able to support up to 20,000 connected devicesand can operate at approximately 15 km in suburban settings and 2 km in dense urbanenvironments.

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 fourthgateway for the region.

Floods and binsThe first big project to make use of the technology uses flood sensors which feed databack to the council every 15 seconds. Two were deployed in Bradford Beck and Shipleyfour 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 theplanning 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 normallyreactive regarding flood threats. But analysis of patterns in the data will meanwe 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 oneof several ideas to have come to fruition. Another idea from the event was presented byBradford Beck, a community group lobbying to put sea life back into the river. The projectwill include use of water purity sensors to monitor PH levels and ensure the conditions areright for the reintroduction of wildlife.

Another Lorawan-based scheme currently on trial is the management of council binsusing 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 andwork out where we should remove or put additional bins. This will save timeand 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, roadmonitoring and sound sensors.

HealthIdeas around improvement of social care or health are central to the council’s LoRaWANproject. It is working closely with Bradford University and The DHEZ to develop these withthe aim of allowing vulnerable or elderly people to live on their own for longer. One ideacurrently under consideration would see sensors placed inside the plant pots of elderlypeople. If watered less frequently, they would raise an alarm, as this may indicate adeterioration for dementia patients.

Similarly, computing researchers are collaborating with the University, the DHEZ and thedepartment of adult services at the local authority to develop sensors for wearabledevices that would monitor blood pressure or heartbeat.

They might also be used on doors to ensure they are shut properly or on lights or curtainsto ensure they are being used as normal. Aberrations might indicate some problem thatcan be followed up by social or health workers. Similarly, the same community spacesmight be fitted with sensors to monitor carbon dioxide, or monoxide, as well as act as firealarms 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 whichlocal departments brainstorm with SMEs from the area. The departments are asked topresent problems that the SMEs must solve using IoT technology.

Mayat says:

The ICT department has a grant scheme and will give grants and prizes tothe best ideas to come out of the workshops.

One proposal to come from February’s workshop proposed using sensors to monitorwater coming into and out of people’s homes. The sensors feed data to a household andthe council regarding excessive water use or leaks. The sensors are currently beingtrialled in a house in Bradford. The best ideas will be developed by social impacttechnology start-ups such as Konnecktis or DataFlock.

My takeAlthough 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 aswell as its ready collaboration with bodies such as the DZEH and SMEs in the privatesector make it seen dynamic as few local authorities are. Developers interested in smartcity 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.htmlRédigé par Julien Jormot | Le 15 mars 2017 à 16:04

S’affichant comme l’un des piliers d’une transition énergétique réussie, lescompteurs communicants doivent permettre à tout un chacun de consommer mieuxet réduire sa facture d’électricité. Mais qu’en est-il lorsque la technologie qu’ilsutilisent est imparfaite ?

C’est le point soulevé par une récente étude hollandaise dont les auteurs affirmentavoir enregistré des dysfonctionnements sur certains compteurs qui surévalueraientla consommation des foyers. Cette nouvelle n’a pas tardé à être reprise par lesmédias français s’empressant alors de faire un rapprochement avec le compteurLinky. Pourtant, bien qu’elles soient toutes communicantes, d’un pays à l’autre, lestechnologies présentes dans ces nouveaux compteurs ne sont pas nécessairementles mêmes…

Tout récemment, Le Figaro s’est fait l'écho d'une étude hollandaise publiée le 3 marsdans la revue scientifique hollandaise IEEE Electromagnetic Compatibily Magazine. Selonles chercheurs bataves, certains compteurs nouvelle génération dits « intelligents »transféreraient des données erronées aux centrales de gestionnaires de réseauxélectriques du pays. De fait, des chercheurs de l'université de Twente (Pays-Bas) encollaboration avec l'université d'Amsterdam des sciences appliquées ont étudié neufcompteurs intelligents, construits entre 2004 et 2014. Cinq donnaient des résultats plusélevés – parfois de manière significative – que la consommation réelle. Deux autres desrésultats en deçà de la réalité.

L’équipe de scientifiques explique ces décalages par l’émergence de nouvellestechnologies en matière d'éclairage domestique – par exemple les nouvelles ampoules àbasse consommation et LED – qui altèrent en effet la forme « parfaite » du courantélectrique, le rendent en conséquence plus difficilement mesurable. La technique demesure – appelée l'effet Hall – était donc inadaptée. Les compteurs observés « n'ont passuffisamment tenu compte des dispositifs de commutation modernes », explique FrankLeferink, professeur de Compatibilité électromagnétique à l'université de Twente, dans unarticle qui relate les résultats de leur étude.

Il faut noter que les compteurs « intelligents » sont censés communiquer directement laconsommation du foyer où ils sont installés, sans qu’un technicien ne doive venireffectuer une relève sur place. Leur fiabilité est donc cruciale afin d’assurer unefacturation juste aux usagers. Or, il a été observé que dans des cas isolés, certainscompteurs envoyaient des bilans tantôt trop élevés, tantôt sous-évalués. De quoi posercertaines 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 cesinquiétudes, 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 étudequi concerne un modèle différent (et par ailleurs moins sophistiqué), le parallèle peutlaisser penser qu’une défaillance similaire pourrait se produire en France. Une crainte à

laquelle Enedis – filiale d’EDF, qui procède actuellement au déploiement des compteursLinky – vient répondre au travers d’un communiqué de presse. Enedis assure ainsi que leboitier français « ne peut être associé à cette étude ». Pour la société, ce bug ne peutaffecter leurs modèles, car « les constructeurs Sagemcom, Itron, ZIV et Elsterdéveloppent 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 rappelleque « la mesure est réalisée via un « shunt » (résistance de faible valeur) pour lescompteurs monophasés et/ou un transformateur de courant pour les compteurstriphasés ». Le groupe poursuit : « les dispositifs de commutation, telles les ampoules àbasse consommation ou LED, sont parfaitement intégrées et comptabilisées par lescompteurs ». Linky a en effet pris en compte les évolutions technologiques qui ontperturbé le modèle des Pays-Bas. Une information confirmée indépendamment par leLaboratoire 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 cedepuis 2009 où un premier lot de 300 000 compteurs avait été installé en Indre-et-Loire età 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 réseaud’électricité, s’associent pour confirmer la fiabilité métrologique des compteurscommunicants actuellement déployés sur le territoire français.

Une étude de l’université néerlandaise a récemment mis en cause l’effet Hall et l'effetRogowski 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 quin’utilisent pas de capteurs à effet Hall ou Rogowski pour l’acquisition métrologique, car ilsreposent sur une mesure réalisée via un « shunt » (résistance de faible valeur) pour lescompteurs monophasés et/ou un transformateur de courant pour les compteurstriphasés.

Le constructeur Landis+Gyr utilise une méthode différente de mesure basée sur une solution Embedded Coil qui garantit l’ensemble des exigences légales métrologiquespour toutes les conditions représentatives du terrain.

En matière de fiabilité métrologique, les compteurs Linky répondent à la norme MID. Etpour aller au-delà de cette norme, ENEDIS a imposé à chacun des constructeurs depasser des « essais d’immunité aux perturbations conduites en mode différentiel avec unegamme de fréquence 2-150kHz » afin de respecter la norme EN 61000-4-19. Cette normefait référence au rapport technique CLC/TR 50579, et permet de s’assurer que lesdispositifs de commutation, telles les ampoules à basse consommation ou LED, sontparfaitement intégrées et comptabilisées par les compteurs.

Enfin, Le LNE* a certifié les compteurs Linky conformément à la Directive EuropéenneMID 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 duterritoire après avoir subi des tests très poussés au sein du LNE, chez les constructeursmais également au sein du laboratoire d’Enedis. En plus des salariés d’Enedis, 10 000hommes et femmes sont mobilisés au quotidien pour fabriquer, remplacer et recycler lesanciens compteurs.

Turin to become Italy’s first 5G city, aimsfor total deployment by 2020Source 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 municipalitysigned a memorandum of understanding with Telecom Italia (TIM).

The project is expected to start its metropolitan trial in 2018, with the aim of covering thewhole city by 2020. The telco will install more than 100 small cells in the main areas of thecity, as well as at both the city’s universities, with 3,000 users being made part of the trialprocess.

While plenty of the industry discussion around 5G has been that of bluff and bluster – itwas the second most frequently cited term at MWC behind the Internet of Things – moreconcrete 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 totest 5G last month, while Amsterdam, one of 13 cities hosting the European FootballChampionship in 2020, hopes to use the network to transmit high quality video streams atthe tournament.

“The project is expected to start its metropolitan trial in 2018, with the aim of covering thewhole city by 2020. The telco will install more than 100 small cells in the main areas of thecity, as well as at both the city’s universities, with 3,000 users being made part of the trialprocess.”

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 aminimum 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 beachievable.”

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 thatunderlying all this there is always quality and the speed of the networks,” said GiuseppeRecchi, TIM executive chairman. “TIM has the privilege of being a leading company in thedevelopment of the digital culture of the country and today this agreement adds anotherimportant element to our strategy.”

“It is a positive sign that TIM has chosen Turin as an urban area to test an innovativetechnology such as 5G, linked to the mobile network,” said Chiara Appendino, mayor ofTurin in a statement. “The high speed services and applications can only bring benefit, inthe immediate future, to the manufacturing world and the community.”

Going further down the line, the proposal will also take into accountsmart cityplans, frommanaging public transport fleets, to remote surveillance and virtual reality for tourism, aswell asIndustry 4.0initiatives.

Roberto Minerva, chairman of the Internet of Things initiative at IEEE, cites Venice as anexample of an Italian city which was ‘challenging’ to get off the ground as a smart city. Hetold 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 acombination of the technology, and the ability of the technology to capture a large numberof data in that specific environment,” he said.

According to the GSMA, commercial 5G networks will be ‘widely deployed’ by thebeginning of the next decade, with connections to hit 1.1 billion globally by 2025.

Schneider Electric targets IoT and edgeapps with micro data centreSource 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 connectedproducts, for what it is calling a faster, easier and more effective way to build and deploymicro 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) softwaresuite, StruxureWare for Data Centres, is built on its EcoStruxure integrated architectureplatform. The service can be integrated into a customer’s larger IT-asset monitoringsystem or a managed service provider’s RMM and remotely managed via the cloud formaximum 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 toservice.

“Edge computing solves real-time data transmission issues by bringing bandwidth-intensive content and latency-sensitive applications close to the users or data sources toensure reliable connectivity.”

It is designed to enable customers to pre-install IT equipment before shipment, andcomes with complete data centre physical infrastructure and management software in asingle self-contained and secure enclosure.

In addition to this, Schneider Electric also delivered its new Ecoflair Indirect AirEconomizer cooling solution, a new system that is able to reduce operating costs by over60 percent.

The new system uses a proprietary polymer heat exchanger technology, which provides acost-effective and highly energy efficient approach to data centre cooling.

Ecoflair is available in 250kW and 500kW modules and is designed to offer flexible andgreater customisation, based on the cooling requirement and local condition, simplifiedinstallation and associated expenses. This also includes increased serviceability togetherwith lowered maintenance costs.

The rate of the reduced costs enables a greater proportion of data centre energy to beavailable 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 systemsbased on chilled water or refrigerant technologies, the overall efficiency of Ecoflair hasbeen 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 overallCAPEX due to a smaller electrical infrastructure needed from a smaller electricaldistribution and back-up power requirements.

Its scalable approach is said to make the Ecoflair system to be particularly suited forcolocation facilities between one and 5MW (250kW modules) and large hyperscale orcloud 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 deploymentand reduce operational and maintenance costs.

The Micro DC Xpress will be available to order in UK, North America and France in April2017 and to be deployed across Europe later in the year.

Big data lab to boost digital economySource URL: http://www.chinadaily.com.cn/business/2017-03/14/content_28543800.htmBy Ouyang Shijia | China Daily | Updated: 2017-03-14 08:51

China launched its first national engineering laboratory for big data distribution andexchange technologies on Saturday.

The move is seen boosting the country's digital economy and helping build its strengthsto compete in the global market.

Yang Shanlin, director of the lab and an academician at the Chinese Academy ofEngineering, said the lab will seek breakthroughs in the research and application of bigdata.

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 datacollection, open data and data security. In terms of applying big data to industries, we willbuild innovation centers and conduct research in key technologies for industries likefinance, media, advanced manufacturing, energy, healthcare and education."

He also said the lab will research policy, to help set quality and service standards in bigdata.

The lab was approved by the National Development and Reform Commission, China's topeconomic planner, in February.

The lab will be led by Shanghai Data Exchange Corp. Other backers include ChinaInternet 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 andapplications of big data in different fields," said Tang Qifeng, CEO of Shanghai DataExchange 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 wascontributed by Shanghai Data Exchange Corp and its partners.

With more than 700 million internet users and over 1.3 billion mobile phone users, Chinais among the largest data producers on the globe, and is entering a period of rapiddevelopment of information and technology industries.

From 2010 to 2015, China has doubled its sales in the information industry, hitting 17.1trillion yuan ($2.47 trillion), according to a government plan unveiled in January.

Project Sunroof Now Predicting RooftopSolar Potential In All 50 US StatesSource 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 providea 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 toprovide 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 employeescan work on in 20% of their time at Google, which sometimes then get branded as aGoogle product with the company’s full backing. Project Sunroof uses imagery fromGoogle Maps and Google EARTH, 3D modelling, and machine learning to estimate howmuch sunlight a given rooftop receives, helping to answer how much energy a givenrooftop could produce if it had solar panels.

Google announced on its The Keyword blog this week that Project Sunroof is nowproviding data for all 50 US states, and according to Joel Conkling, product manager, theexpanded data has shed some light (get it?) on some interesting insights about thepotential US solar industry:

79% of all rooftops analyzed are technically viable for solar, meaning those rooftopshave enough unshaded area for solar panels.Over 90% of homes in Hawaii, Arizona, Nevada, and New Mexico are technicallyviable, 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 Sunroofdata, with an estimated 18,940 gigawatt-hours (GWh) of rooftop solar generationpotential per year. Los Angeles, Phoenix, San Antonio, and New York followHouston for the top 5 solar potential cities — see the full top 10 list in the chartbelow.

“If the top ten cities above reached their full rooftop solar potential, they’d produceenough energy to power 8 million homes across the US,” Conkling said.
