Bringing Better Networking to LTE IoT

  1. 1. Bringing Better Networking To LTE IoT
  2. 2. 2 Challenges In Bridging The LTE IoT Gap Today, Neither LTE IoT standard supports real-time, low power networking 1. Both LTE Cat M1 and NB-IoT are physical layer only 1. Not a complete networking stack 2. TCP/IP is default networking stack 1. Slow, onerous handshaking and authentication 2. NOT low power 3. Weak P2P and ad hoc networking support 4. Can’t support important IoT use cases
  3. 3. 3 The “Haystack Option” Place parallel, low power real-time networking stack with TCP/IP • Two stacks that run concurrently on same silicon • TCP/IP connectivity for conventional WAN comms • DASH7 connectivity for indoor/LAN applications including indoor location, P2P/ad hoc networking • Additional security + other features • Benefits • Minimal memory footprint impact. Haystack (DASH7) compiles into <30KB • No carrier gateway/base station mods required, DASH7 connectivity is LAN-based • Provides viable enterprise market entry strategy for cellular IoT
  4. 4. 4 Result: Complete LPWAN-LAN Connectivity Sample Use Case: Extend Supply Chain Visibility Gaps That WAN’s Can’t Address WAN provides basic wide area visibility via GPS, cellular trilateration Haystack LAN provides indoor location where GPS and cellular trilateration fail LPWAN Provides Wide Area Location, Environmental Visibility Haystack LAN adds to WAN: ‣ Precision, real-time location features ‣ “Hotspot” data transfers ‣ 2-factor authentication ‣ Possible to enable distributed 
 chain-of-custody features ‣ No extra chips Haystack Powered LPWAN-LAN Provides Precise Indoor Location, Environmental Visibility
  5. 5. 5 IoT LTE LoRa SSMSK • SDR-based 4G basebands that can support a range of standards from GSM to OFDM-types are capable of being modified in firmware to support emerging IoT modulations. • Nearly all emerging IoT modulations (SSMSK) have lineage from GSM and CDMA specifications, and represent simple enhancements. source: http://www.slideshare.net/obamalab/4g-iphone-platform-by-open-wireless-architecture-presentation Goal: add emerging IoT modulations to 4G baseband, as a firmware- only solution. Enabling Haystack via LTE
 GMSK Modulation (and others) can be synthesized by 4G/LTE baseband transceiver

  11. 11. 11 Indoor Location with Haystack
  12. 12. 12 AP 1. Access point keeps network synchronized, and gets vertex data from users in the Endpoint 2. Endpoints are mobile, battery- powered devices 3. Small battery or USB-powered “reference nodes” are placed on fixed things & places
  13. 13. 13 AP Today, neither LTE Cat M1 or NB-IoT offers a high-precision, real time, indoor location capability on its own. But Haystack does this. Endpoint Using RSSI & RF “fingerprinting” with scattered reference nodes: ±1m precision has been observed
