. The former Sigfox entity had raised more than $300 million from investors that included Salesforce, Intel, Samsung, NTT, SK Telecom, energy groups Total and Air Liquide. In November 2016 Sigfox was valued at around €600 million. In January 2022 it filed for bankruptcy. In April 2022 Singapore-based IoT company UnaBiz acquired the Sigfox 0G technology and its French network operations for a reported €25 million ($27m). As of December 2024, the Sigfox 0G network managed by UnaBiz supports over 14 million active connected devices worldwide.

Sigfox employs differential binary

phase-shift keying Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time. I ...

(DBPSK) and Gaussian frequency shift keying (GFSK) over the Short-range device band of 868 MHz in Europe, and the Industrial, Scientific and Medical radio band of 902 MHz in the US. It utilizes a wide-reaching signal that passes freely through solid objects, called " Ultra Narrowband" and requires little energy, being termed a " low-power wide-area network" ( LPWAN). The network is based on one-hop star topology. The signal can also be used to easily cover large areas and to reach underground objects. As of December 2024, the Sigfox 0G global network has covered a total of 5.8 million square kilometers in a total of 75 countries with 1.3 billion of the world population reached. The Sigfox 0G technology is supported by a number of firms in the LPWAN industry such as NXP Semiconductors, Holtek, ST Microelectronics, Semtech and Silicon Labs. The ISM radio bands support limited bidirectional communication. The existing standard for Sigfox communications supports up to 140 uplink messages a day, each of which can carry a payload of 12

Upon acquisition, UnaBiz released the Sigfox device library code for connected objects to the public and IoT development community to drive technology interoperability and the unification of LPWANs in the IoT industry.
