Duty cycle

* Duty cycle is 1% of the time per hour (36 seconds). For an 8 to 12 bytes payload, this means 6 messages per hour,
140 per day.
** Frequency hopping: The device broadcasts each message 3 times on 3 different frequencies. Maximum On time
400 ms per channel. No new emission before 20 s.
*** Listen Before Talk: Devices must verify that the Sigfox-operated 200 kHz channel is free of any signal stronger
than −80 dBm before transmitting.
Sigfox’s high limit EIRP recommendation is included in each column although regulations sometimes allow for more
radiated power than the Sigfox recommendation.
Sigfox’s recommendation is set to comply with the Sigfox technological approach of:
Low current consumption
Balanced link budget between uplink and downlink communication
