  3. 3. How to ask a question • Visit http://forum.link-labs.com/ to submit your question
  4. 4. What is LPWA? • Low Power, Wide Area Networks • Low data rate = High sensitivity = Long Range • Multiple Access = One-to-Many Architecture • Mostly Unlicensed Spectrum = duty cycle limits (ETSI) or time-on-air limits (FCC) • Carrier Deployed vs. Customer Deployed
  5. 5. History of LPWA 1990-2000s 2G/3G 2000s ARDIS Network 2010s 2014-2016
  6. 6. Licensed vs. Unlicensed Spectrum • 902-928 MHz • 868 MHz (EU) • Can’t count on band quality • Licensed use in band
  7. 7. Technology Snapshot LTE Cat-M1 • What is this? • 1.4 MHz Frontend (vs. 20 MHz) + 1 Antenna • 1 Mbps Half-Duplex Less Expensive Chipset Power Saving Mode (PSM) Extended Discontinuous Reception (eDRx)
  8. 8. LTE Cat-M1 • Very good US Coverage* • TCP/IP Network – Connect to any server • Fast data rates • Can be very power efficient • Better UL power utilization than NB-IOT • Power budget • Carrier Firmware Upgrades use power • Areas with limited coverage • System costs higher than some LPWA • Must implement IPSec • IPR Risk • Certification Advantages Considerations * In 2017, Verizon and ATT
  9. 9. LTE Cat-M1 Key Takeaways • It will be available by mid 2017 nationwide in US. • Provides power efficient data transport, with (relatively) high speeds. • Modules costs ~$15, data $1 - 3/mo • Look for LTE CAT-M “only” modules that do not require Linux and long boot times out of PSM.
  10. 10. LTE-M Sensor Suite • PTCRB and VZN Certified communication board • Open source power/sensor board • Open Source Atmel L21 project for user application
  11. 11. Link Labs IOTSystem Communications and Host Board Power and Sensor Board Enclosure Subscription and Data Management Application Enablement in Hours • LTE – M • NB – IOT • Symphony + Atmel Host MCU with open source libraries and community + + + • Battery • Solar • AC/DC • Open Source + Huge array of available sensors (GPS, IO, Motion, Environmental, etc) • Internal Antennas • Indoor rated • Outdoor (IP67) + Fast customization via our enclosure partners • Manages MNO Subscription • Manages data post endpoint • Handles sleepy device addressing • Firmware upgrades Confidential for Telit
  12. 12. Technology Snapshot NB-IOT • How is this different? • Cat- NB1 • 200 kHz • Max 144 kbps uplink • Half Duplex • Chipsets could be slightly less than LTE-M1
  13. 13. NB-IOT • Good hardware prices • Link Margins are Good • Data Rates Support FOTA and advanced Use Cases • Less IPR Risk • Much better bi-directional data than most unlicensed LPWA • No US Announcements • Monthly Subscription • Not TCP/IP Direct • May be limited to Europe/Asia initially • No mobility, only idle- rejoin Advantages Considerations
  14. 14. NB-IOT Key Takeaways • If LTE-M is “LTE-Light,” then NB-IOT is LPWA on steroids. • Appropriate for sending “sensor messages” but not data streams. • Deployments in 2018. US may lag significantly. • Modules <$15?, Service costs? • Market perception about advantages over LTE Cat-M1 (Power, cost, coverage) do not hold.
  15. 15. Technology Snapshot SIGFOX • Narrowband psuedo-DBPSK (MSK) • Hundreds of Uplink Channels • Completely Asynchronous • Transmit 3 times and hope • Limited Downlink • Uses “Stock” UHF RF Chips
  16. 16. SIGFOX • Good hardware prices • Hard to Jam • Simple to implement • Very small payloads: 12 bytes • Americas/US Coverage Lacking • Vendor Risk Advantages Considerations
  17. 17. SIGFOX Key Takeaways • For simple, infrequent sensors, a good choice, if there is network coverage. • Modules <$10, Data costs <$1/mo
  18. 18. Technology Snapshot LoRaWANTM • Based on LoRa PHY Technology • Asynchronous Uplink • “Dumb” Gateway, “Smart” Cloud • Hybrid Business Model – Carrier + DIY The LoRa® name, LoRa® logo and LoRaWAN™ are trademarks of Semtech Corporation or its subsidiaries in the U.S. and/or other countries.

  20. 20. LoRaWAN • Good hardware prices • Simple to implement • Do-it-yourself option • Good ecosystem of vendors • Needs Cloud Server for MAC • Messages lost at >15% capacity or with ACKs • Dynamic Range Losses • Complicated Key Management • 1% Duty Cycle Limit (EU) • Shared Channel Interference • Additional Application Requirements Advantages Considerations
  21. 21. LoRaWAN Key Takeaways • Good do-it-yourself option for simple applications. • Identity and provisioning management is complex. • Message delivery not guaranteed. • Multiple gateways may be needed. • Firmware upgrades not really possible.
  22. 22. LoRa is an RF Technology. Symphony Link is an Industrial IOT System. LoRa Link Labs
  23. 23. Technology Snapshot Symphony Link • Uses LoRa Hardware • Different Protocol Stack • Synchronous / Slotted • Quality of Service • 100% Acknowledgements • Repeaters • Firmware-over-the-air • Multicast/Control • Auto-provisioning • No cloud needed
