Star Network Architecture

A device is not attached to a specific base station unlike cellular protocols. The broadcasted message is received by any base station in the range, which is 3 in average.

Small Payload

An uplink message has up to 12-bytes payload and takes an average 2s over the air to reach the base stations which monitors the spectrum looking for UNB signals to demodulate. For a 12-byte data payload, a Sigfox frame will use 26 bytes in total. The payload allowance in downlink messages is 8 bytes.

Lightweight Protocol

SIGFOX has tailored a lightweight protocol to handle small messages. Less data to send means less energy consumption, hence longer battery life.

Ultra Narrow Band radio modulation

Using the Ultra Narrow Band modulation, Sigfox operate in the 200 kHz of the publicly available band to exchange radio messages over the air. Each message is 100 Hz wide and transferred at 100 or 600 bits per second a data rate, depending on the region. Hence, long distances can be achieved while being very robust against the noise.
