A farming Arduino

Arduino Pro redefines smart agriculture with the new Edge Control

Experience the intelligent future of outdoor environments Arduino Pro announces the launch of the Arduino Edge Control, a smart remote solution for monitoring and control, designed to deploy AI on the edge. Optimized for outdoor environments and easy to place anywhere, it is ideal for precision farming, smart agriculture, and any application requiring intelligent control in isolated locations.The Arduino Edge Control can be expanded with 2G, 3G, CatM1, or NB-IoT modems, Lora, Sigfox, Wi-Fi, or Bluetooth connectivity; it can be managed remotely via the Arduino Cloud or third-party solutions and powered via solar panels. The option to power the device via solar panels as well as the range of connectivity options means the Edge Control can be used in the most remote of locations and monitored from afar. The Arduino Edge Control is able to connect sensors, provide real-time monitoring and automatically drive actuators – such as latching valves commonly used in agriculture – reducing production-related risks. Through this advanced solution, smart agriculture sensors collect data about weather conditions, soil quality, crop growth, and more. The data is then sent to the Arduino IoT Cloud, where valuable analytics can be retained to support business at different levels – enabling better decisions about equipment efficiency, plant growth, and staff productivity, or even automating processes such as fertilization, irrigation, and pest control to boost the quality of crops and minimize human error. During product development, Arduino partnered with Challenge Agriculture to integrate the Edge Control into Irriduo®, the French company's new smart irrigation solution and water management application, the first in a new generation of water management products. Combining Challenge Agriculture's R2-DX with the Arduino Edge Control , Arduino MKR GSM1400 for connectivity and firmware, and including access to a dedicated cloud, Irriduo® takes a closer look at the soil to actively tell farmers how to achieve the best yield while minimizing water consumption and maximizing soil preservation. The inherent nature of arable farming sets its own unique set of challenges: remote locations, changeable soil conditions based on field topography, and specific crop rotation schedules to mention but a few. Challenge Agriculture and Arduino worked to create an optimal solution for these needs, with 6 sensors per field providing accurate readings for 6 crop cycles of 3-4 months each (i.e. 4,000 measurements), or for as long as 4 years in the case of perennial crops. Constant sensing and monitoring are only half the story - by automating irrigation controls, Irriduo® also reacts in real-time to changing conditions. This is especially important in regions suffering from droughts, where strict regulations are enforced to limit the volume of water that can be used and the time of day/night irrigation can be activated. Commenting on the launch, Arduino’s CEO Fabio Violante said, “People are constantly needing to solve everyday problems and improve productivity through their own creativity and ingenuity, and we truly believe they can do this with the Edge Control. We are ready to help companies take the next step in agricultural automation, providing smart irrigation solutions and the ability to apply machine learning on the edge to optimize crop production and increase yields.” Xavier Eftimakis, Founder & CEO at Challenge Agriculture, added, “The Edge Control allows many cost-effective solutions for multiple smart agriculture projects.” The Edge Control’s robust design and solar-powered capabilities mean that it is suited for controlling applications in any outdoor environment. For example, it can be used on construction sites and real estate to monitor and automate access control; moreover, swimming pool maintenance and cleaning companies could take advantage of its capabilities to change their service offering by monitoring and controlling the condition of the pool water remotely. As usual, it is expected that countless ingenious solutions will be provided by the Arduino community using this technology. The Arduino Edge Control is available for €166/US$199 on the Arduino Store. For more information, please visit: arduino.cc/pro

IoT Standards & Protocols Guide - Arya College

The essence of IoT is networking that students of information technology college should be followed. In other words, technologies will use in IoT with a set protocol that they will use for communications. In Communication, a protocol is basically a set of rules and guidelines for transferring data. Rules defined for every step and process during communication between two or more computers. Networks must follow certain rules to successfully transmit data.

While working on a project, there are some requirements that must be completed like speed, range, utility, power, discoverability, etc. and a protocol can easily help them find a way to understand and solve the problem. Some of them includes the following:

The List

There are some most popular IoT protocols that the engineers of Top Engineering Colleges in India should know. These are primarily wireless network IoT protocols.

Bluetooth

Bluetooth is a wireless technology standard for exchanging data over some short distances ranges from fixed and mobile devices, and building personal area networks (PANs). It invented by Dutch electrical engineer, that is, Jaap Haartsen who is working for telecom vendor Ericsson in 1994. It was originally developed as a wireless alternative to RS-232 data cables.

ZigBee

ZigBee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols that are used by the students of best engineering colleges to create personal area networks. It includes small, low-power digital radios like medical device data collection, home automation, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, ZigBee is a low data rate, low-power, and close proximity wireless ad hoc network.

Z-wave

Z-Wave – a wireless communications protocol used by the students of Top Information Technology Colleges primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance which allows wireless control of residential appliances and other devices like lighting control, thermostats, security systems, windows, locks, swimming pools and garage door openers.

Thread

A very new IP-based IPv6 networking protocols aims at the home automation environment is Thread. It is based on 6LowPAN and also like it; it is not an IoT protocols like Bluetooth or ZigBee. However, it primarily designed as a complement to Wi-Fi and recognises that Wi-Fi is good for many consumer devices with limitations for use in a home automation setup.

Wi-Fi

Wi-Fi is a technology for wireless local area networking with devices according to the IEEE 802.11 standards. The Wi-Fi is a trademark of the Wi-Fi Alliance which prohibits the use of the term Wi-Fi Certified to products that can successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology mainly include personal computers, digital cameras, video-game consoles, smartphones and tablets, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet through WLAN and a wireless access point. Such an access point has a range of about 20 meters indoors with a greater range outdoors. Hotspot coverage can be as small as a single room with walls that restricts radio waves, or as large as many square kilometres that is achieved by using multiple overlapping access points.

LoRaWAN

LoRaWAN a media access control protocol mainly used for wide area networks. It designed to enable students of private engineering colleges in India to communicate through low-powered devices with Internet-connected applications over long-range wireless connections. LoRaWAN can be mapped to the second and third layer of the OSI model. It also implemented on top of LoRa or FSK modulation in industrial, scientific and medical (ISM) radio bands.

NFC

Near-field communication is a set of communication protocols that enable students of best engineering colleges in India two electronic devices. One of them is usually a portable device like a smartphone, to establish communication by bringing them within 4cm (1.6 in) of each other.

These devices used in contactless payment systems like to those used in credit cards and electronic ticket smartcards and enable mobile payment to replace/supplement these systems. Sometimes, this referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC used for social networking, for sharing contacts, videos, photos,or files. NFC-enabled devices can act as electronic identity both documents and keycards. NFC also offers a low-speed connection with simple setup that can be used by the students of top btech colleges in India to bootstrap more capable wireless connections.

Cellular

IoT application that requires operation over longer distances can take benefits of GSM/3G/4G cellular communication capabilities. While cellular is clearly capable of sending high quantities of data. Especially for 4G with the expense and also power consumption will be too high for many applications. Also, it can ideal for sensor-based low-bandwidth-data projects that will send very low amounts of data over the Internet. A key product in this area is the SparqEE range of products including the original tiny CELLv1.0 low-cost development board and a series of shield connecting boards for use with the Raspberry Pi and Arduino platforms.

Sigfox

This unique approach in the world of wireless connectivity; where there is no signalling overhead, a compact and optimized protocol; and where objects not attached to the network. So, Sigfox offers a software-based communications solution to the students of top engineering colleges in India. Where all the network and computing complexity managed in the Cloud, rather than on the devices. All that together, it drastically reduces energy consumption and costs of connected devices.

SigFox wireless technology is based on LTN (Low Throughput Network). A wide area network-based technology which supports low data rate communication over larger distances. However, it mainly used for M2M and IoT applications which transmits only few bytes per day.

Hardware solutions for Eclipse IOT Challenge: Exploring LoRa/LoRaWAN

The Eclipse IOT challenge lead me to research more in depth different technologies both from the hardware and the software aspect. As part of product development and delivery one has to come up with the solution for a problem. In this case the problem is parking in urban areas, or the lack of smarter parking solutions. Such implementation would not only allow end users to have a better parking experience while saving time in finding an adequate spots but also provides the city with valuable data to be used for city planning and city improvement projects.

Once the issue is identified, it was important to find a technical solution that would align with our needs. For city implementations, given the broad area that needs to be covered, we would need a type of communication that is long range and low cost, both in cost of sending data and power consumption. I first tackled the hardware needs once the design was evaluated. The prototype for a smart city solution needs to also be scalable while adding the least overhead in cost and infrastructure needed.

In this article I will go more in depth on the research done to identify one of the key components of the project. I will share a summary of my findings in hopes of helping others that are also exploring similar solutions.

Evaluating communication solutions:

I evaluated BLE, bluetooth, cellular, satellite, Wi-Fi, SigFox, Zigbee and Lora. Bluetooth and Wi-Fi, given its range limitation and cost were not considered for this prototype. Cellular communications have a higher cost as well, and at even steeper price comes satellite communication; both this options were also discarded. SigFox and LoRa/LoraWAN were the runner up candidates. I came across a comprehensive post on the comparison of SigFox and LoRa that is worth the read https://www.link-labs.com/blog/sigfox-vs-lora . The winner was LoRa.

Why Lora?

As explained by Libelium on http://www.libelium.com/development/waspmote/documentation/lora-vs-lorawan/ LoRa contains only the link layer protocol and is perfect to be used in P2P communications between nodes. LoRa modules are a little cheaper that the LoRaWAN ones.. LoRaWAN includes the network layer too so it is possible to send the information to any Base Station already connected to a Cloud platform. LoRaWAN modules may work in different frequencies by just connecting the right antenna to its socket..

LoRa which stands for long range wireless operates at a low bandwidth, meaning that its best application is for sending smaller pieces of data such as sensor data. LoRaWAN is known for its good penetration and long coverage which has been recorded to reach over 10 KM distance. LoRaWAN operates on unlicensed bands, so in most countries is legal to have you own LoRaWAN gateway cutting down the cost given that you will not have to pay a carrier or third party to supply you with the service.

Additionally a selling point for me personally was the wide accessibility to various developer platforms and hardware solutions such as DIY LoRa kits, libraries and Arduino compatible LoRa modules. The Things Network offers a strong platform with access to resources, documentation and a great community of IOT LoRa enthusiast.

Gateway

Lets take a look at one of the hardware pieces now. “Gateways form the bridge between devices and The Things Network. Devices use low power networks like LoRaWAN to connect to the Gateway, while the Gateway uses high bandwidth networks like WiFi, Ethernet or Cellular to connect to The Things Network. Gateways are routers equipped with a LoRa concentrator, allowing them to receive LoRa packets”(see more at https://www.thethingsnetwork.org/docs/gateways/).

Based iC880a concentrator board and a Raspberry Pi 2.

A DIY low-cost LoRa gateway

http://cpham.perso.univ-pau.fr/LORA/RPIgateway.html

The gateway is based on a Raspberry PI. RPI 1B+/2B/3B can be used. The LoRa modules comes from (a) Libelium LoRa radio module, (b) HopeRF RFM92W/HopeRF RFM95W (or RFM96W for 433MHz), © Modtronix inAir9/inAir9B (or inAir4 for 433MHz), (d) NiceRF LoRa1276. Libelium LoRa and RFM92W use the Semtech SX1272 chip while RFM95W, inAir9/9B and NiceRF LoRa1276 use the SX1276 which is actually more versatile.

Note: The LoRa module and the LoRaWAN module are not compatible because the protocols are different. The LoRa module implements a simple link protocol, created by Libelium. However, the LoRaWAN module runs the LoRaWAN protocol, a much richer and more advanced protocol, created by the LoRa Alliance.

Check out their Github page with detailed documentation https://github.com/CongducPham/LowCostLoRaGw

Conclusion on gateways:

The gateway is a key portion of this solution given that the sensors will need to send the information “somewhere” where it can either be analyzed on the edge or sent to the cloud. After considering price ranges on both the parts needed for a DIY solution or a full blown gateway I considered those solutions that would be cost effective and which I was most familiar with. The “LG01 LoRa OpenWrt IoT Gateway by Dragino Tech” seemed the best approach. The developer kit counts with an Arduino developer node and a Developer gateway. Note that this solution only counts with ONE channel, in comparison with other solutions that allow 8+ channels. This was a compromise that was evaluated and given that this will be a prototype the one channel option seemed sufficient.

In the following articles I will showcase both the remaining hardware parts and the software portion along with updates on how the project is coming along.

How does LoRa sensor works

Those sensors which are based on LoRa technology is known as a LoRa sensor. LoRa sensors have capabilities for geolocation, allows for low power consumption and long-range transmissions (typically more than 10 km). Hence, we can use these via timestamps from various gateways to triangulate positions of devices. LoRa sensors allow for long-range connectivity between devices to allow for an effective Internet of Things (IoT) implementation. This has applications across multiple industries.

How Does LoRa Sensor Send and Receive data

A LoRa network uses LoRaWAN protocol for sending and receiving data from LoRa sensors. LoRaWAN is a cloud-based media access control (MAC) layer protocol but acts mainly as a network layer protocol. We use LoRaWAN for managing communication between LoRa gateways and LoRa devices (nodes). It functions as a routing protocol and the LoRa Alliance maintains it. The first version of LoRaWAN was released in the year 2015.

LoRaWAN defines the system architecture and the communication protocol for the LoRa network. It allows for a secure and reliable long-range communication link. LoRaWAN also manages data rates, communication frequencies, and power optimization for all LoRa devices.

LoRa nodes in a LoRa network are based on asynchronous communication, and they start transmitting when they have data available to send. This enables a LoRa network to trade off sensitivity for data rate with a fixed channel bandwidth. It mainly involves selecting the amount of used spread (which is a selectable parameter between 7 and12). This spreading factor determines the sensitivity of a LoRa node and determines its data rate.

Data transmitted by a LoRa node is received by multiple LoRa gateways, which forward the received data packets to a centralized network server (IoT server). The IoT server filters out the duplicate packets, manages the network and performs security checks. The server then sends this data to the application modules, control panels, or connected smart devices. This way LoRaWAN protocol shows high reliability and accuracy for the moderate load.

Additionally, LoRa uses Forward Error Correction coding. This improves the LoRa network's resilience against any kind of high interference. The high range of a LoRa network is characterized by very high wireless link budgets, which are around 155 dB to 170 dB.

How to make LoRa Sensors?

We typically integrate LoRa sensors into IoT networks. The sensors which we mostly use with LoRa technology are,

DHT11

It is a basic temperature and humidity sensor.

Ultrasonic Sensor

We use this sensor for checking if there is an object in front of it.

Photosensitive sensor

We use this sensor for monitoring the ambient light.

Flame sensor

It detects the presence of fire or a flame.

Relay

We use this for controlling the power of a device.

Buzzer

We use this for alarming or warning nearby individuals.

LED

These are for showing the progress or status of any process.

A collection of these sensors when combined with a GPS module via a microcontroller (usually Arduino or Raspberry Pi), forms a LoRa Sensor.

How to use LoRa sensors?

For using a LoRa sensor, we have to set up an effective LoRa Network. A typical LoRa network includes the following,

1. LoRa Node

A LoRa sensor, when embedded with wireless connectivity and LoRa protocol, then it forms a LoRa Node. A LoRa node collects the required sensor data and sends it over to the LoRa Gateway.

2. LoRa Gateway (LG01) A gateway is generally a device which we use for connecting various types of Network. LG01 is a LoRa Gateway which we use for bridging the LoRa wireless network and IP network. Its main features are,

a. It is the central point for forming a LoRa network.

b. Receives data from LoRa device (Node) in LoRa Network via LoRa wireless and sends it to IoT server in the IP network via

Wi-Fi

Ethernet

3G/4G etc.

c. Receives command from the IoT Server and sends it to LoRa device (Node).

3.IoT server

An IoT server is basically a cloud server that allows connectivity between various devices. It receives and stores data from multiple devices and allows access across multiple platforms. In the case of a LoRa network, the IoT server receives data from the LoRa Gateway and then stores it accordingly. This data can is then accessible from any smart device (A computer, laptop, mobile phone, or tablet, whichever is convenient).

When we want to scale the performance of LoRa sensors up or down or if we want to increase or decrease the range of their measurements, then the IoT server also allows for that. In this case, we send the commands from the control panel (any smart device) to the IoT server. The IoT server sends the command to the LoRa gateway, which in turn sends it to the Lora Node (device). The command is interpreted at the LoRa node, and the LoRa sensors follow it accordingly.

So, this is how we set up LoRa sensors within a LoRa network. A LoRa network can accommodate as many LoRa sensors as required.

Why Use LoRa Sensors?

LoRa technology, compared to other disruptive technologies, is not a promise of the future but is available today throughout the world. There are 600 known cases of deployment of LoRa technology in citywide IoT implementations, and this number is growing steadily. According to an estimate, more than 105 million LoRa devices are deployed around the world. LoRa sensors combined with the LoRaWAN protocol are helping in creating a smart world. Analysts predict that by 2023, around 43% of all IoT implementations will incorporate LoRa technology. Hence, LoRa technology is realizing the potential for IoT applications.

LoRa Technology Fills a Technological Gap

LoRa technology is revolutionizing IoT by using very little power and enabling data communication over a long-range. LoRaWAN fills the technology gap of Wi-Fi/BLE and cellular-based networks, which require either high power or high bandwidth and have the inability to penetrate shielded indoor environments or have a limited range. Hence, LoRa technology is efficient for usage in any indoor or rural settings.

2. LoRa Technology Complements Other Technologies

LoRa technology operates in the unlicensed band like Wi-Fi and is very secure from end devices to the IoT server like Cellular. This makes it suitable for both indoor and outdoor use. LoRaWAN protocol offers a flexible, economical, and efficient connectivity solution that is ideal for IoT applications, whether installed in private, public, or hybrid networks. LoRa sensor data can fuel analytics platforms that use machine learning and artificial intelligence. These technologies need data diversity, which is accommodated by LoRa sensors at a very low cost and power consumption.

3. Global Network Availability

LoRa devices (nodes) operate on the LoRaWAN protocol, which is an open standard. It is backed by the LoRa Alliance, a nonprofit association that is promoting worldwide adoption of LoRa technology. The ecosystem of LoRa alliance has over 500 members, which include 100 public network operators with service offerings in more than 58 countries. LoRaWAN based networks are globally accessible and are available in more than 100 countries. Therefore, this existing and established infrastructure makes it more efficient and easier to immediately deploy LoRa based solutions.

4. A Rapidly Growing Ecosystem

The ecosystem supporting LoRaWAN and LoRa includes a wide range of hardware manufacturers, service providers, network operators, software designers, universities, and industry associations. These play an integral role in creating devices, applications, and networks. The ecosystem is growing rapidly, and entities are adopting LoRa technology across multiple segments.

What are some prospective applications of LoRa Sensor ?

LoRa Sensors offer a wide range of possibilities that we can use for applications across multiple sectors. Some of the prospective applications of LoRa sensors are,

Smart Agriculture

IoT is widely being used in agriculture from measuring environmental conditions that affect crop production to tracking the health indicators of livestock. This allows for the minimum strain on the environment, maximization of yield, and minimization of expenses. LoRa devices (nodes) and LoRaWAN protocol can significantly improve the effectiveness of such networks. Some case studies have shown that the use of LoRa sensors has reduced the water consumption of commercial farms up to 50%. LoRa sensors have long-range connectivity and consume low power. Hence, they are able to send data from agriculture farms to the Cloud Server. The data is processed and analyzed there for improving operations.

2. Smart Cities

We can make municipal operations more efficient with the long-range and low power LoRa sensor. These sensors provide secure and GPS-free geolocation capacities. If city services such as parking, lighting, and waste removal are connected together, then cities can optimize the use of personnel and utilities for saving money and time.

3. Smart Healthcare

The low cost and low power consumption of LoRa sensors make them suitable for healthcare applications, which are critical and require reliability. IoT solutions based on LoRa sensors and gateways can help in monitoring high-risk patients around the clock. Therefore, this will help in ensuring that the medical safety and health of critical patients is never overlooked.

4. Smart Industrial Control

Operations in the industry can benefit from the LoRa sensors, which have continuous monitoring functions. Due to long-range and low power consumption of LoRa devices (nodes), we frequently use them in manufacturing industries and plants. They can also relay important data via LoRaWAN protocol to the concerned network. This can allow for analysis of data and subsequent optimization of business operations.

5. Smart Utilities

Conventional utility operations use subjective measurement by field technicians, and hence, they are labor-intensive. On top of that, meters are often located indoors, underground, or dense urban environments. This makes it difficult for most wireless technologies to reach them. So, using LoRa sensors and LoRaWAN protocol will allow metering and utility companies to collect data remotely. Therefore, it will also help them in streamlining the operations by using their personnel more efficiently.

6. Smart Supply Chain & Logistics

LoRa sensors make it affordable and easier for logistics and supply chain to track high valued assets that are in transit. The long-range and low power consumption of LoRa sensors makes it easier for GPS-free geolocation of vehicles and cargos. Hence, we can easily monitor any kind of assets within harsh environments and large geographic regions.

7. Alzheimer Patient Tracking

LoRa technology wearable tracking devices can alert caregivers when an Alzheimer patient leaves a designated safe zone. This will help in ensuring round the clock safety in the absence of physical supervision.

8. Smart Homes & Buildings

LoRa sensors can send data even from within buildings constructed from dense materials, and they consume low power. This makes LoRa sensors ideal for manufacturing smart home and building devices. Additionally, long-range capabilities of LoRa sensors and LoRaWAN protocol allow them to track assets that may stray away from home. LoRa sensors in smart home and building applications can optimize utility usage, detect danger, and improve the safety & convenience of daily life.

9. Smart Refrigeration Solutions

LoRa technology can help in smart refrigeration solutions, which can help in tracking food temperatures for the food retail industry. Global developments in established supermarket chains can save a lot of money every year. LoRa sensors can also help restaurants in reducing food waste and optimize the operational costs of food management.

IoT: sortir de l'Internet des Silos

Il ne passe pas un jour sans qu'on entende parler du dernier saint Graal: la plateforme IoT. Une plateforme qui connectera tous les objets de l'entreprise, en remontera les données via un réseau et exposera ces données sous la forme d'API prêtes à s'intégrer dans vos applications ou sous la forme d'un tableau de bord prêt à l'emploi. L'internet des objets serait donc en train de réaliser sa promesse de 30 à 50 milliards d'objets en 2020 et surtout des milliards d'économies en performance industrielle et nouveaux services ? Mais ce qui ne rassure pas GreenSI ce sont toujours les discours un peu trop marketing, avec des idées simplistes qui sèment la confusion chez les décideurs IoT, qu'ils soient en train d'urbaniser leur "smart city" ou de moderniser leur "usine 4.0". Ce billet va essayer d'éclairer une de ces idées, souvent poussées par ceux qui auraient un intérêt à ce qu'elles se réalisent...

L'internet des objets sera interopérable

Pour GreenSI, dans l'idée même de l'internet des objets, donc une nouvelle ère de l'internet qui va connecter à l'échelle de la planète les objets en plus des humains, la notion d'interopérabilité finira par s'imposer. Un feu rouge ou un réverbère de marque X devra pouvoir envoyer des informations à une plateforme Y par le réseau Z. Cette interopérabilité sera soit "restreinte" au sein de grands écosystèmes qui auront décidé de partager des standards communs, soit native par l'émergence de standards plus globaux comme dans la v1 de l'internet avec IP ou Http.

A la clef, notamment au niveau des équipements et des réseaux, la capacité de trouver les business modèles qui financeront cet internet avec des logiciels plus intelligents qui dégageront des économies ou de nouveaux revenus en exploitants ces nouvelles données. Sans cette valorisation, l'internet des objets sera stérile et surtout non financé, mais comme pour la ruée vers l'or il aura enrichi les vendeurs de pioches. On se souvient il y a 30 ans du hardware "PC compatible IBM" qui en se déployant a été le fédérateur de l'industrie logicielle qui a pu se développer comme on l'a connue par la suite. Si cette interopérabilité n'arrive pas, l'internet des objets risque d'être réduit à un "Internet des silos" comme l'appelait Philippe Krief de la fondation Eclipse dans une de ses conférences. Des silos comme aujourd'hui les distributeurs automatiques de billets (DAB), ces objets connectés partout en ville depuis 30 ans qui continuent de ne délivrer que des billets, avec une interopérabilité limitée aux banques - on peut retirer des billets dans le DAB d'une banque en ayant un compte dans une seconde - alors qu'en 30 ans ils auraient pu devenir multi-services et générer des revenus additionnels (au delà du chargement des cartes de mobiles). Tous ceux qui ne jurent que par une plateforme unique, voir un duopole, ont certainement l'agenda caché de vouloir reproduire le réseau des DAB et de vendre de pioches.

Le billet publié cette semaine sur Les Echos pour "Faire de la France un nouveau laboratoire mondial de l'Internet des objets" a attiré l'attention de GreenSI. La première vision simpliste de ce billet est de ne mettre en avant que la partie réseau alors que la plateforme IoT commence bien sûr par les objets. Et la France regorge de Fablabs pour les fabriquer, c'est une compétence reconnue et enviée, comme avec celui #FrenchTech d'Orléans : le Lab'O.

La France a aussi un mouvement des "makers" très dynamique et même d'une Citée de l'objet connecté à Angers, également #FrenchTech, une ville qui va accueillir en octobre 2017 le prochain WEF, le forum mondial de l'électronique, une technologie de base de l'IoT. L'atout de la France sur ce premier niveau du modèle IoT est donc certain. Sur le niveau des applications également il ne fait aucun doute. La seconde vision simpliste est surtout de limiter les réseaux connectés aux objets à deux réseaux, Lora et Sigfox, ceux qui ont certainement les budgets marketing les mieux fournis. Pourtant l'IoT en France et l'avenir de l'Internet ne s'écrira pas avec seulement ces deux sigles, souvent seuls cités par la presse. Même en France ça n'est déjà plus le cas quand on analyse les usages dans le détail et aux États-Unis l'histoire reste à écrire. Il y a bien sûr de multiples moyens de connecter les objets industriels en commençant par le Wifi 802.11 où la bonne vielle carte SIM en 3G ou 4G. Et puis ce serait oublier les réseaux déjà en place dans les villes pour télé-relever en France les compteurs d'eau et de gaz (LPWA 169Mhz) et qui sont autant d'atouts pour la France comme laboratoire de l'IoT pour tous les usages dans l'environnement ou pour la performance énergétique quand on recherche une longue portée et une très faible consommation d'énergie ou capter à l'intérieur des bâtiments. Sans compter comme nous le rappelle l'analyste Gartner, les réseaux qui arrivent prochainement à maturité comme la 5G ou le NB-IoT et qui vont redistribuer les cartes. Les standards sont donc encore largement ouverts.

Sur le long terme, la question de la technologie réseau est surtout celle de sa pérennité pour l'entretenir et maintenir un coût d'accès (abonnement) abordable. La pérennité des acteurs financés par des levées de fonds sera fonction de l'atteinte rapide des objectifs commerciaux fixés par les actionnaires. A l'inverse avoir une première base installée d'usages stables comme le comptage des fluides et une roadmap de déploiement du réseau financée pour cet usage jusqu'en 2022, avec des engagements jusqu'en 2042, est certainement un atout solide pour la longue portée 169MHz et son Alliance Wize. La technologie n'est donc pas tout dans ces choix, l'existence de suffisamment de clients avec des usages sur le moyen-long terme est aussi essentiel. Alors pour ne pas tomber systématiquement dans la simplification, l'image à garder pour le moyen terme c'est d'imaginer l'internet des objets comme un internet interopérable à trois niveaux, les objets, les réseaux (via des gateways) et les plateformes pour développer les usages. Il y aura des milliards d'objets mais aussi des dizaines de réseaux disponibles sur un territoire, et c'est tant mieux pour réduire les futures zones blanches et choisir le réseau le plus adapté en fonction des usages souhaités.

Un internet des objets plateforme de développement

L'Internet des objets doit être également être vu comme une plate-forme de développement aussi diversifiée et interopérable qu'innovante. Il impacte déjà les architectures des SI pour intégrer le temps-réel et la sécurité et fait en fait émerger de nouvelles.

Diversifiée car comme pour les réseaux, il serait illusoire de croire qu'il n'y aura que quelques plates-formes sur lesquelles on pourra développer les technologies de l'IoT. L'histoire des GAFAs qui ont dominé l'Internet 1.0 et 2.0 avec leurs plateformes mondiales centralisées ne sera pas facile à reproduire pour l'Internet des objets car il faudrait être à la fois leader sur le matériel, de la voiture au bracelet montre en passant par la machine outils, et en même temps sur le logiciel dans tous les métiers de l'entreprise. Android a certes pris un temps d'avance mais Android est ouvert et pour l'instant son modèle n'est pas celui du contrôle. L'analyste IDC présente un classement des éditeurs de plateformes, qui se verraient bien en nouveaux GAFAs de l'Internet des objets: IBM Watson, PTC Thingworx, GE Predix... Des plateformes qui sont fonctionnellement redondantes en partie avec les services offerts par ceux qui opèrent les réseaux pour gérer les objets ou les configurer. En revanche elle vont plus loin sur le traitement des données et les tableaux de bords temps réel. Mais comme trop souvent dans ces classements d'analystes, les solutions open source sont oubliées. Ce graphique n'est donc pas complet et les revenus de ces éditeurs ne sont pas pertinents pour apprécier les leaders d'une chaîne complète "objet - réseau - plateforme - applications smart". Or dans l'Internet des objets l'open source est omniprésent dans les choix logiciels mais aussi matériels, par exemple avec la plateforme de cartes Arduino, un standard ouvert qui permet de faire des prototypes d'objets ou avec le Raspberry Pi sous Linux pour plus de puissance de calcul embarquée. La société Smile a d'ailleurs écrit un ouvrage pour recenser les solutions open source pour l'IoT et un autre pour les solutions Linux dans des systèmes embarqués. On pourra y vérifier le poids de l'open source. Côté logiciel on va retrouver l'incontournable Node-RED qui permet de créer le "câblage numérique" nécessaire pour les données le long de ces nouvelles chaînes de mesures. Un code qui s'exécute ensuite soit dans l'objet soit dans le Cloud.

Ensuite côté portails ou applications mobiles pour développer les usages et valoriser les données, l'open source a déjà démontré sa capacité à être une plateforme incontournable pour de simples applications web (Symfony2, Angular, ...) à l'analyse des données massives (Hadoop, Spark...). Donc pour échapper au chant des sirènes marketing, la bonne question à poser aux vendeurs de technologies est finalement simple: comment votre solution est interopérable horizontalement avec vos pairs et verticalement dans la chaîne de communication ? Si elle ne l'est pas aujourd'hui, elle devra l'être demain, sinon les projets IoT termineront dans les limbes de "l'internet des silos". Des silos souvent relayés par la presse et les analystes qui aiment bien les histoires simples, mais après les premiers prototypes, ces histoires simplistes pourraient mal se terminer pour les investissements à long terme. from www.GreenSI.fr http://ift.tt/2tUnfyl
