Key Document


The TIDA-00816 reference design has wireless sub-1 GHz communication in a star network between multiple sensor nodes (in this case, fault passage indicators) and a collector using the TI 15.4-stack. This design is optimized for low power consumption for short range (< 50 m) using overhead fault passage indicator (FPI) and a data collector in distribution automation as an application scenario. The CC1310 device from TI's Simplelink family is a highly-integrated, single-chip solution incorporating a sub-1 GHz radio frequency (RF) transceiver and an ArmTM CortexTM M3 MCU. TI 15.4-stack is used to configure beacon mode communication over the US, ETSI, and China frequency bands. Current consumption data is available for a single packet data transfer of 1–300 bytes at a 50-kbps data rate by optimizing transmit power levels (0 to +10 dBm) and beacon intervals (0.3–5 s).

  • Low power consumption for short range communication (≤ 50 meters) for FPI, data collector, substation and distribution automation end equipment:
    • Receive current below 6 mA and transmit current below 16 mA (at +10 dBm)
    • Average current consumption below 20 µA for five second beacon interval (sensor node in receive mode) in a star network
    • Current consumption data provided for US (915-MHz), ETSI (868-MHz), and China (433-MHz) frequency bands
  • Integrating low power RF in grid automation with details on:
    • Network setup
    • Beacon transmission and reception
    • Data exchange
    • Fault identification and data communication
  • Advantages of using CC1310:
    • Low active RF and microcontroller (MCU) current consumption with standby current of 0.7uA with RTC running and RAM and CPU retention
    • TI’s 15.4 stack is used to configure beacon-enabled communication between collector and sensor (fault indicator) node
    • TI SimpleLinkTM platform enables seamless integration with MCU portfolio
