  4. Rich and Flexible Wireless Software Libraries

  5. A Z-Stack solution is… • Standardized • Interoperability using application profiles • Off the shelf solutions/tools/modules • A mesh network (robust/self healing) • Aimed at large networks (hundreds of nodes) • Intended for monitoring & control applications • Easy to deploy (low installation cost) • Between 64 and 128 Kbytes in size; depends on configuration • Full-featured • Frequency agility, routing, over the air download, binding, cluster library, security • Supported on all 2.4GHz IEEE 802.15.4 compliant platforms • DSSS included in the HW of the IEEE 802.15.4 compliant CC products

  6. A SimpliciTI solution is… • Simple • Very basic 7 – 9 function-call API • Low Cost • Uses < 12K FLASH, 1K RAM depending on configuration • Aimed at small RF networks • Networks that require long battery life, low data rate • Simple star + routers or p2p topology • Low power – sleeping end devices • Highly flexible • Full source code and low-level implementation provides high design freedom • Achievable with many Stellaris + LP-RF transceiver pairs • CC1101 (1GHz), CC2500 (2.4GHz), CC2520 (2.4GHz 802.15.4)

  7. A Proprietary Solution is… • Full SW design freedom • You can implement exactly what you need/want • Optimal code size • Possible to leverage the lower layer of SimpliciTI (MRFI layer) • You can use any TI LP RF transceivers with Stellaris • Any frequency, modulation, topology • Only limitation given by regulations like FCC, ETSI, etc…

  8. 13.56 MHz ISO 14443 is… • An 8 kbit memory chip with a radio • An automatic way to collect information or data on People, Products, Places, Times, or Transactions • Identification performed in milliseconds: • No line of sight required • Contactless • Works in a harsh environment • ID “Tags” that can: • Read & write unique ID information • Perform encryption (3DES) and authentication • Be read simultaneously • Impervious to most materials, with the exception of metals • Tags are mainly in label (flat) format and moderately inexpensive.
