  • 3. 1. Introduction 3
  • 4. M2M: The Next Big Thing Important historical events: • Early 1990s: digital technology drove deployment of Supervisory control and data acquisition systems (SCADA) as industrial control system with multiple sites and large distances. • 1995: Siemens set up a dedicated department inside its mobile phones business unit to develop and launch a GSM data module called “M1”[7] based on the Siemens mobile phone S6 for M2M industrial applications, enabling machines to communicate over wireless networks. 2000: the modules department formed a separate business unit inside Siemens called "Wireless Modules" which in June 2008 became a standalone company .The first M1 module was used for early point of sale (POS) terminals, in vehicle telematics, remote monitoring and tracking and tracing applications. • • 2009 : AT&T and Jasper Wireless entered into an agreement to support the creation of M2M devices jointly. They have stated that they will be trying to drive further connectivity between consumer electronics and M2M wireless networks, which would create a boost in speed and overall power of such devices. • 2010: in the U.S., AT&T, KPN, Rogers, Telcel / America Movil and Jasper Wireless began to work together in the creation of a M2M site, which will serve as a hub for developers in the field of M2M communication electronics 4
  • 5. M2M: The Next Big Thing Definition: Information exchange between devices without any human interaction (sensors,smart meters,…) Is M2M hype or the future of our information society? M2M in the context of the mobile Inernet has been a subject of intense discussion over the past three years Next technology revolution after computer and The Internet cautious with wait-and-see attitude 5
  • 6. M2M: The Next Big Thing Predictions and statistics: • Revenues of US $300 billion [ Harbor Research 2009] • 50 million connected devices by 2020 [AT&T] or only 100M true M2M deployments exist today along with over 1 million innovators are working on smart devices [Intel] • Use of M2M devices will grow to 100 devices per person [Wirefree at TIA 2012] Big industry players (Ericson, Samsung, Alcatel-Lucent ,….)

  • 11. M2M & IoT 11
  • 12. M2M Trends 1. Device functionality and usage models 1.1.Indirect nodes and sensors : provide monitoring services , and frequently use WPAN 802.11 wireless communication. 1.2. Direct nodes: operates in a stand-alone capacity to send & receive data. 1.3. Gateways: aggregate data from indirect nodes and sensors and deliver commands back using multiple radio technologies. 12
  • 13. M2M Trends 2. Innovative solutions from horizontal providers: M2M Application Platforms (MAP) are enabling over-the-air provisioning and software updates for devices as well as implementing the policy and security to protect data and policy. Key functions are Dashboards, Enterprise connectivity , and Secure Remote Access. 3. Vertical markets are expanding : Initial M2M deployments have been focused on the energy industry and smart meter deployments. This has been accelerated by the European Commission mandates for Smart Grid and Smart Metering technology. Video infotainment and auto telemetry are growing markets. Industrial, building and home automation industries are expected to begin deploying M2M as well. Another important vertical market is the medical equipment industry where there will most likely be subset markets that deploy M2M; for example in-home patient care versus in hospital care or assisted living options. 13

  • 15. M2M Elements 3 key elements at the core of M2M: 1.Mobility: the distribution and consumption model of these services will primarily be mobile. so the need for a platform and architecture to securely mobilize the data into consumable consumer and enterprise applications becomes critical. 2.Big Data: connecting the physical world is creating a data exhaust of incredible volume. With the addition of social channels like Facebook and twitter, the Big Data challenge must deal with unstructured data in addition to the structured data generated by devices, sensors, and machines. the key challenge is to convert this data into information and wisdom. This will require entirely new software platforms, tools, and techniques, including in-memory analytics, device connectivity, event-driven execution, and dynamic user experiences to enable this brave new world. 15
  • 16. M2M Elements 3.The Cloud: Best developments of M2M communications to manage hundreds of devices are implemented in the cloud. This allows providers to manipulate more effectively the knowledge derived from the Big Data without extra infrastructure. Communication solution providers (CPSs) are positioned to take a leadership role in this marketplace. 16
  • 17. 2.M2M Applications and Usage models 17
  • 18. M2M Applications An increasingly useful way of assessing the market opportunities in M2M is by categorizing M2M applications into three different types: 1.After Market : category of applications usually involve retrofitting connectivity to products already installed and working in the field, for example connecting vending machines and monitoring environmental conditions. They tend to automate operations already running and are typically introduced to gain operational cost savings. These applications occur in all business sectors and require high levels of technical support to implement. As a result, they tend to be relatively low to medium volumes and medium to high cost per unit. 2.Regulatory : applications are created by the introduction of new regulations, usually associated with particular applications. Road pricing for Heavy Goods Vehicles in Germany and congestion charging in London are typical applications, as are smart metering applications in a growing number of countries 18
  • 19. M2M Applications An increasingly useful way of assessing the market opportunities in M2M is by categorizing M2M applications into three different types: 3.Line Fit/OEM: are most often driven by product manufacturers , acting either in concert with partners or on their own, to create new services opportunities related to their products . These applications can apply to almost any product in any sector, so the opportunities are particular broad. A classic example of this is OnStar Telematics in the US. 19
  • 20. M2M Applications 20
  • 21. M2M Usage Models 1.Utilities (Smart Grids) : Smart grid integrates communication capabilities with utility generation (e.g., electric power, gas,water) and delivery infrastructure to automate monitoring and control. Significant savings in resource consumption when utility supply is dynamically matched with demand like smart metering, distribution network automation. M2M-enabled smart meter : to collects utility usage information from home appliances via short- range radio or a home area network. The M2M aggregation device : collects information from many smart meters in the area and sends the aggregated information to the M2M application server. 2.Vehicular Telematics : Most vehicular M2M applications can be categorized into one of the following: safety and security, Information and navigation, diagnostics, or entertainment. An example of a safety and security service is Automatic Crash Notification. This service utilizes various crash sensors on the vehicle to report the location and extent of damage to the vehicle in the event of a crash. 21
  • 22. M2M Usage Models 3.Healthcare (M-Health) : M-Health is a nascent market aimed at improving the quality of patient care and reducing Healthcare costs like telemedicine to improve patient care by virtue of more accurate and faster reporting of changes in the patient’s physical condition,Or remote patient monitoring and care, wherein a patient wears bio-sensors to record health and fitness indicators such as blood pressure, body temperature, heart rate , and weight. These sensors forward their collected data to an M2M device (e.g., a patient’s cellphone) that acts as an information aggregator And forwards the data to the M2Mapplication server in the cloud. 22
  • 23. M2M Usage Models 4. Secured Access & Surveillance / Public safety M2M applications meant to prevent theft of vehicles and insecure physical access into buildings. Buildings and vehicles can be outfitted with M2M devices that forward data in real time to the M2M serve whenever movement is detected. An alert signal can then be sent to the M2M user whenever car tampering or building intrusion has occurred. M2M devices can also be configured to trigger M2Mequipped Surveillance cameras to record and transmit video in real-time to the M2M server when movement is detected. 5. Tracking, Tracing, and Recovery Mainly related to services that rely on location-tracking information. For example, in order to provide vehicular tracking services such as navigation, traffic information, road tolling, automatic emergency call, pay as you drive, etc. tracking/tracing/recovery of animals, persons, leisure vehicles (boats, RVs,etc.), construction equipment, plant machinery, shipments, and fleet vehicles. WAN M2M services allow a company totrack its fleet, get breakdowns of miles covered, analyze average speeds and identify/respond to driver issues. 23

  • 25. 3. M2M Standards & Architecture 25
  • 26. Standards for M2M Industry has become more active in standardizing M2M Because of the market demand Multitude of technical solutions result in slow development of M2M market Cost-effective solutions Essential for long term development of technology For interoperability of networks Ability to “roam” M2M services over international frontiers Reduced complexity Due to potentially heavy use of M2M devices and thus high loads onto networks, interest from ETSI TC M2M and recently oneM2M Partnership Project 3GPP (GSM, EDGE GPRS, UMTS, HSPA, LTE) IEEE 802.16 (WiMAX) The starting point is to have popular M2M applications identified and then refine scenarios in each application to identify the areas needing standards. 26
  • 27. Examples: EU Mandates European Commission Mandate 411 March 2009: to build standards for European smart meters, (electricity / water / heat / gas) allowing interoperability and Consumer actual consumption awareness. Reaching completion with a final set of standards expected Q1 2013 European Commission Mandate 490 March 2011: to build standard European Smart Grids. Entering Phase 2, with issues identified for Security and privacy of sensitive data – ICT standards have been included in the list of referenced standards. ETSI TC M2M is coordinating work inside ETSI and contributing to the mandates M411 and M490. 27
  • 28. ETSI: TC M2M 2009: Technical Committee (TC) created for M2M service level standards Mission: develop standards, identify gaps, and re-use existing standards Very collaborative (e.g., with 3GPP, BBF, OMA, industry fora, etc.) Participants: (2009 figures) 28
