STMicroelectronics introduced a high-performance, low-power wireless transceiver for Automatic Meter Infrastructure (AMI) and other wireless sensor node applications, such as alarm and security systems, home and building automation, and industrial monitoring and control.
The SPIRIT1 transceiver handles the communication between smart meters in households and businesses and the neighbourhood data concentrator, which relays the information to the utility provider control centre. By enabling short-range transmissions in frequency ranges below 1 GHz, the device ensures proper wireless signal propagation through concrete walls and building structures.
SPIRIT1 boasts receiver sensitivity of -120 dBm and supports advanced technologies like frequency hopping, auto-acknowledgement and antenna diversity to secure error-free data transmission even in harsh environmental or challenging logistical conditions.
Additional embedded features include 128-bit data encryption, error correction and detection, FIFO memory blocks, as well as highly flexible and programmable data packet management, which contribute to reducing the computation load of the host microcontroller and the overall system cost.
