Our portfolio of sub-1GHz solutions includes transmitters, transceivers and modules supporting a host of different applications in home and building automation (Smart Home and Smart City) as well as industrial process control (Smart Factory) and automated metering infrastructures (Smart Grid) or, more broadly, for the Internet of Things (IoT).

They support network operated in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz and several modulation schemes such as 2(G)FSK, 4(G)FSK, OOK and  ASK.

ST transceivers also support advanced technologies such as frequency hopping, auto-acknowledgment and antenna diversity to secure error-free data transmission even in harsh-environmental or challenging-logistical conditions

Our Sub-1GHz modules, operating in IMS and SMD band, are based on our transceivers and are equipped with antenna, xtal and balun. Modules are available with or without the host microcontroller for enhanced flexibility. They provide a ready to use solution, fully RF, ETSI, IC and FCC certified, that helps minimize time to volume.

Our ICs and module are supported by an extensive set of evaluation boards, software, firmware and application notes.

SPIRIT1 ultra-low-power sub-GHz RF transceiver

The SPIRIT1 high-performance wireless transceiver boasts an outstanding receiver sensitivity of  120 dBm combined with an unparalleled competitive advantage of extremely low current consumption. This enables SPIRIT1-equipped applications to operate for up to twice the time over existing solutions without the need to replace the batteries. The transceiver also supports advanced technologies such as frequency hopping, auto-acknowledgment and antenna diversity to secure error-free data transmission even in harsh-environmental or challenging-logistical conditions.

Extend battery lifetime with ultra-low power, high-performance, sub-1GHz RF transceiver

The  S2-LP transceiver is designed for superior RF performance and unparalleled energy efficiency extending battery life from months to more than 10 years. The embedded radio guarantees an RF link budget in excess of 140 dB besides a compelling output power up to +16 dBm, resulting in a robust and reliable communication link. The S2-LP is ready for Sigfox, Wireless M-Bus, 6LowPAN and IEEE 802.15.4g networking connectivity, simplifying the design of IoT applications and enabling remote sensors to directly connect to the cloud without the need for a local gateway.
