Products & Services

For network functioning the technology of supernarrowband wireless connectivity is used. The network is based on topology "star". By the way, such topology is characteristic of most LPWA. A set of devices on wireless connection transfer data to gateways, and gateways redirect information on the server. Each device can transfer up to 140 outgoing messages a day to networks. The volume of the message does not exceed 12 bytes. The maximum quantity of incoming messages – 4, the volume of everyone – up to 8 bytes.

The network works with not licensed frequency range. For communication services provision the range of 868 MHz in Europe and 902 MHz in the USA is used. Sigfox networks are developed more than in 26 countries of the world.

Sigfox published^[1] at the beginning of 2019 of the specification of the radio protocol for the connected objects. Earlier the company provided specifications only on a request and within the nondisclosure agreement.

The release of these specifications will give more opportunities to developers and producers of the connected objects. Having tested development, the producer will need to register the object in Sigfox network. Sigfox expects that it will sharply increase quantity of the objects connected to its network. The ecosystem of Sigfox will extend in process of democratization of technologies out of limits of producers of devices, said in the message^[2]. Base stations and infrastructure of Sigfox still remain are protected by patents.
