Our portfolio of sub-1 GHz solutions includes transmitters, transceivers, modules and System-on-Chips 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, 512, 868, and 915 MHz and several modulation schemes such as LoRa, 2(G)FSK, (G)MSK, 4(G)FSK, BPSK, 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-1 GHz modules, operating in IMS and SMD band, are based on our transceivers and are equipped with antenna, xtal and balun. They provide a ready to use solution, fully RF, ETSI, IC and FCC certified, that helps minimize time to volume.

Our Sub-1 GHz SoCs, are the firsts in the world to combine an STM32 architectural basis and a LoRa radio on the same silicon die. They offer ease-of-use, affordability, BOM costs optimization capabilities, reliability, while being perfectly tailored for a wide range of industrial and consumer applications.

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