PWM duty cycle

The Things Network restrictions If you use The Things Network (free public community LoRaWAN network), the following fair use policy applies: The uplink airtime is limited to 30 seconds per day (24 hours) per node. The downlink messages are limited to 10 messages per day (24 hours) per node .

Duty Cycle = Pulse Width (sec) * Repetition Frequency (Hz) * 100 .

The current LoRaWAN specification exclusively uses duty-cycled limited transmissions to comply with the ETSI regulations [9]. In fact, each device is limited to an aggregated transmit duty cycle of 1% that means 36 seconds per hour .22 Eki 2020

Duty Cycle indicates the fraction of time a resource is busy . When a single device transmits on a channel for 2 time units every 10 time units, this device has a duty cycle of 20%.
