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).
