Sigfox

Sigfox 0G technology is a global Low-Power Wide-Area (LPWA) networking protocol founded in 2010 and adopted by 70+ Sigfox 0G Network Operators globally. This wireless network was designed to connect low-power objects such as electricity meters securely, at low-cost, emitting small amounts of data. Sigfox is based in Labège near Toulouse, France, and once had over 375 employees in Madrid, San Francisco, Sydney and Paris. 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. Following the acquisition, national operators that owned their own infrastructure continued service independently. In Mexico, the network operator reported processing over 8 million messages daily from more than 500,000 endpoints without service interruption during or after the insolvency process.
