Sigfox

Sigfox employs differential binary phase-shift keying (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.{{cite book|author1=Giedre Dregvaite|author2=Robertas Damasevicius|title=Information and Software Technologies: 22nd International Conference, ICIST 2016, Druskininkai, Lithuania, October 13-15, 2016, Proceedings|url=https://books.google.com/books?id=ApcoDQAAQBAJ&pg=PA665|date=30 October 2016|publisher=Springer|isbn=978-3-319-46254-7|pages=665–}} The signal can also be used to easily cover large areas and to reach underground objects.{{cite book|author1=Khaldoun Al Agha|author2=Guy Pujolle|author3=Tara Ali Yahiya|title=Mobile and Wireless Networks|url=https://books.google.com/books?id=_BzfDAAAQBAJ&pg=PA241|date=17 August 2016|publisher=Wiley|isbn=978-1-119-00755-5|pages=241–}} 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.{{Cite web|url=https://www.sigfox.com/en/sigfox-story|title=Our Story {{!}} Sigfox|last=|first=|date=2020|website=Sigfox|archive-url=|archive-date=|access-date=2020-11-26}}

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 octets at a data rate of up to 100 bits per second, and/or 600bps in some regions.{{Cite web |author=News Desk |date=2024-05-02 |title=UnaBiz reduces device energy consumption |url=https://www.iotinsider.com/news/unabiz-reduces-device-energy-consumption/ |access-date=2025-02-21 |website=IOT Insider |language=en-GB}}{{Cite journal|last1=Augustin|first1=Aloÿs|last2=Yi|first2=Jiazi|last3=Clausen|first3=Thomas|last4=Townsley|first4=William Mark|date=2016-09-09|editor-last=Kim|editor-first=Dongkyun|title=A Study of LoRa: Long Range & Low Power Networks for the Internet of Things|journal=Sensors|volume=16|issue=9|pages=2–3|doi=10.3390/s16091466|pmid=27618064|pmc=5038744|bibcode=2016Senso..16.1466A|doi-access=free}}

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.{{Cite web |title=UnaBiz puts Sigfox device library in public domain |url=https://www.iotm2mcouncil.org/iot-library/news/iot-newsdesk/unabiz-puts-sigfox-device-library-in-public-domain/ |access-date=2025-02-10 |website=IoT M2M Council |language=en-US}} The developer community can now visit the 0G technology’s [https://github.com/sigfox-tech-radio Github page] and [https://build.sigfox.com/new-sigfox-open-souce-protocol-library?__hstc=43356922.13164a2f029bd024df3715b046fa94c3.1726112798900.1738914145379.1739159571355.99&__hssc=43356922.1.1739159571355&__hsfp=3380644065 Build] to access the new device library codes and related documentation.
