ST's SPIRIT1 transceiver handles the communication between smart meters in households and data concentrator, which relays the information to the utility provider control center. By enabling short-range transmissions in frequency ranges below 1 GHz, SPIRIT1 ensures proper wireless signal propagation through concrete walls and building structures.
SPIRIT1 boasts an outstanding receiver sensitivity of -120dBm. It delivers an unparalleled competitive advantage of extremely low current consumption, slashed by as much as 50% over existing solutions in the market. It is packaged in a very small QFN20 4*4 mm package.
