  4. Internet of Things

  5. Quick Review • An Internet of Things is an “Internet-LIKE” collection of objects that communicate together • Grew out of RFID and tagging • The medium by which the IoT communicates depends on the application(s) and topography

  6. Topography Mesh Star Cluster Tree

  7. Physical Data Link Network Transport Session Presentation Application The ISO:OSI 7 Layer Model

  8. Communications • Optical – bar code, QR, OCR, bio • Passive transponder – RFID • PAN – ZigBee, BTLE, other 15.x • WiFi (802.11x) • ISM • Cell • Wired xxbaseT, CAN, others • Others, “all of the above”

  9. Personal Area Networks • IEEE 802.15.x • BlueTooth • BTLE • 15.4 – low speed • ZigBee • Z-wave • Proprietary (Z-star, SMAC, etc)

  10. WiFi • IEEE 802.11x (x=a, b, d, g, n, etc) • High-speed, high power, medium range • Topography • Point-to-point • Star (tree) • Advantages: universal, bandwidth • Disadvantages: power, crowded BW, multiple access points needed to go beyond star

  11. Free Bands (ISM)

  12. ISM (other than PAN and LAN) • Essentially point-to-point structure, can be made star or even tree with protocols • Advantages: If links already established (PHI and TRANSPORT), can communicate with existing devices. Also can make use of perhaps less crowded frequencies • Disadvantages: roll your own, bands may be geographically limited by regulation

  13. Other channels • Cell (GSM, 3/4G, etc) – “unlimited” range as long as service available. Requires account with carrier. Protocols established. • Wired – (established protocols) • USB • baseT • CAN

  14. Protocols • Each communications channel has its own protocol. Other protocols can be layered on top as needed. • There are some competing protocols being used (and proposed) for networks – more on this Thursday when we discuss standards. • IPv6 is always an option

  15. Tying it Together • Many concepts of the IoT involve using a number of the previous methods for communicating between “things” in the IoT. Tags and RFID may be scanned and read into a location’s database, then that database form a “thing” in a company’s global IoT, along with sensors, geo tracking, and other inputs and controls. • More on this Friday!

  17. Please stick around as I answer your questions! • Please give me a moment to scroll back through the chat window to find your questions • I will stay on chat as long as it takes to answer! • I am available to answer simple questions or to consult (or offer in-house training for your company)c.j.lord@ieee.orghttp://www.blueridgetechnc.com

  18. Apologies to the late Douglas Adams and late Theodor Seuss Geisel for the blatant misuse of their brilliant creative material…You are both missed.
