  1. 1. Where IoT Connects Will Low-Power Devices Bring High-Volume IoT Deployments? An M2M Zone Webinar Moderated by: Robin Duke-Woolley Founder & CEO Beecham Research Presenter: Rod Montrose VP Engineering Numerex Corp. Beecham Research December 10, 2015 Sponsored by:
  2. 2. Introduction Robin Duke-Woolley
  3. 3. As IoT develops, connected devices everywhere”
  4. 4. All Connectivity types have a part to play in IoT 1. Cellular 2G/3G/4G . . . 5G 2. WiFi 3. Bluetooth, ZigBee 4. Fixed Broadband 5. Wireless Broadband5. Wireless Broadband 6. Satellite 7. LPWA – Low Power, Wide Area 8. . . . many others But what about the need for low power edge devices themselves?
  5. 5. Need for low power devices in many sectors
  6. 6. 1. Increasing need for security at the edge 2. Increasing need for processing at the edge. Even sensors becoming more intelligent – and need power 3. Need for data storage at the edge 4. Long distance Some of the challenges 4. Long distance 5. Remote locations 6. Connectivity requirement 7. BUT data from these locations becoming increasingly important – mission critical. Must be reliable.

  8. 8. Where is IoT?
  9. 9. Where is IoT?
  10. 10. What are Low Power IoT Devices? • Low RF Power Short Range Devices ZigBee, BlueTooth Low Energy, Z-Wave, 413/900/2400 MHz ISM • Low RF Power Longer Range Devices SigFox, LoRA, Ingenu and other LPWANSigFox, LoRA, Ingenu and other LPWAN • Low Power Usage Devices Portable or Mobile Device Battery or Power Source with Limited Energy Short or Long Range Need to Conserve Power
  11. 11. What are Low Power IoT Devices? • Low RF Power Short Range Devices ZigBee, BlueTooth Low Energy, Z-Wave, 413/900/2400 MHz ISM • Low RF Power Longer Range Devices SigFox, LoRA, Ingenu and other LPWANSigFox, LoRA, Ingenu and other LPWAN • Low Power Usage Devices Portable or Mobile Device Battery or Power Source with Limited Energy Short or Long Range Need to Conserve Power
  12. 12. Why Low Power Usage Devices? • Devices in Remote Areas or Power Too Expensive to Provide Constant Power is Not Available - Portable One On Site Visit (Truck Roll) can Eliminate any Benefit for M2M • Cannot Change Batteries• Cannot Change Batteries Explosive Atmospheres (Intrinsic Safety) • Issues with Transportation of Lithium Batteries • Very Sporadic Reporting or Information on Demand • Need to Minimize Life Expense of Device
  13. 13. What Are High Volume Deployments? • Supply Chain Asset Management When, Where and How Assets Are Used Assets Integrated with ERP & CRM Systems Low Cost with Long Battery LifeLow Cost with Long Battery Life • Medical Devices Very Low Maintenance with Long Life Battery • Security Long Product Lifetime with Very Low Maintenance Personal Security Needs Battery Operation
  14. 14. Example Use Case Application: Supply Chain Asset Tracking Business Model: Managed Service • Device Supplied with Service • Customer Selects Life of Contract• Customer Selects Life of Contract • Inclusive of Device, Airtime, Application Customer Data Connectivity: • Web Portal • REST API to Gateway Portal
  15. 15. Supply Chain Asset Tracking Use Case • High Value Equipment Manufacturer • Multiple Suppliers • Multiple Manufacturing Facilities Part Location Drives Just In Time• Part Location Drives Just In Time Manufacturing Reduces WIP in Facility • Identify Long Dwell Times http://numerex.com/wp-content/uploads/2015/09/iManage_CaseStudy0805-3.pdf
  16. 16. What is a Managed Service? New Business Models Driving IoT • Managed Service Model Reduces Capital Expenditures • Leads to Faster High Volume IoT Deployments Shared Interest in Customer Success Need to Maintain Margin Drives: • Need to Minimize Costs of Lifetime of Product – Responsible for Device Replacement for Life of Contract • Reduce Support Costs
  17. 17. Supply Chain Device Requirements • 4 Year Battery Life on 1 Set of User Replaceable Batteries • Report Set Times per Day at Rest • Report Set Times at Start, Stop and In-Motion • Location Aware• Location Aware Dynamic and Static Geo-Fences • Asset Condition Tilt Detection Sensor Inputs
  18. 18. How Do We Achieve Low Power Utilization? TechnicalTechnical Discussion Ahead
  19. 19. Technical Challenges for Low Power • Radio Transmitters Cellular Radios often Require >1 Amp Current Pulse Cellular Registration can take 2 minutes or Longer Form Factor often Dictates Small AntennaForm Factor often Dictates Small Antenna • Small Antenna = Reduced Signal = Increases Retries with Higher Power • GPS GPS can take 5 minutes or more to acquire a lock GPS Receivers often Require 30 mA or more Current
  20. 20. Technical Challenges for Low Power Device is Often in Very Low Power Sleep Mode • Difficult to Communicate Communication Only When Awake • Long Latency for Commands Messages Not Received Until Next TransmissionMessages Not Received Until Next Transmission • Long Sleep Cycles Increase Passivation in Lithium batteries Need occasional currents pulse to reduce damage • Cannot be used for Time Critical Monitoring
  21. 21. Technical Challenges for Low Power • Low Cost Often Throwaway Devices • High Reliability Won’t be There to Hand-hold or Replace DeviceWon’t be There to Hand-hold or Replace Device • Long Device Life Need High Physical Security Need to Withstand Environment • NEMA and IP Rating • Material Construction for Environment
  22. 22. Technical Challenges for Low Power
  23. 23. Technical Challenges for Low Power Sensor Power • Power Sensors Only When Measuring Include Setup or Stabilization Time • 4-20 mA Devices Often Need 12V or more to Operate• 4-20 mA Devices Often Need 12V or more to Operate • Pulse Current Requirements • Read Often but Transmit Only for Exceptions Need to Normalize Readings for Thresholds No Linear Devices Need Formulas to Determine Thresholds
  24. 24. Overcoming Technical Challenges Need a Fresh Design • Reusing Normal Powered Device Designs Often Limited by Inherited Technological Decisions • Difference Between Standard Products and Purpose Built TechnologiesPurpose Built Technologies • Measure Power Usage of EVERY Section Under All Modes of Operation • Every Component on Separate Power Control to Minimize Power Usage Leakage currents adds up!
  25. 25.
