This wireless network was designed to connect low-power objects such as electricity meters securely, at low-cost, emitting small amounts of data.

[3][4] 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.

[6] A year later, US semiconductor company Semtech, owner of the LoRa physical-radio layer technology (and licensor of hardware running the LoRaWAN transmission layer network protocol), integrated Sigfox into its flagship LoRa-based hardware and software platforms, marking a seismic turnaround for Sigfox, the original pioneer technology in the LPWAN space.

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 existing standard for Sigfox communications supports up to 140 uplink messages a day, each of which can carry a payload of 12 octets at a data rate of up to 100 bits per second.
