Sigfox, a French startup created in 2010, invented a radio protocol entirely dedicated to connecting objects to the internet by transporting very small messages and producing data like GPS position, temperature, movements, water meter reading, battery life, ...
Supported by local operators around the world, Sigfox is rolling out the "0G Sigfox network", a light and smart infrastructure based on Sigfox radio antennas that can listen to billions of ultra-low powered objects emitting data. The over-the-air communication service in now available in 60 countries and is the largest « Internet of Things » network. Today more than 400 startups are developing objects connected to the Sigfox network.
The vision of Sigfox is to connect billions of objects, and make things come alive around the globe, giving companies, institutions, governments a new information space coming from the physical world.

Sigfox technology features
The device only switches on when transferring a message
Very small messages (12 bytes) and very small amount of energy needed to emit these messages
Only a few messages per day (ETSI regulations)
No pairing (unsynchronized transmission between the device and the network)
Maximum autonomy and power efficiency for remote devices
Sigfox operates on a free and shared portion of the radio spectrum (ISM band)
Very low cost modules (< $2)
Energy efficiency and long-range capabilities lead to a lower cost
City : 2-10 km
Rural : up to 100km
The transmission rate for the message is low. This provides longer range
Secure by design
Encrypted and secured messages
Very concentrated signal that uses a small portion of radio spectrum
Ultra-Narrow Band signals have high resilience to jamming
