Duty Cycle = Pulse Width (sec) * Repetition Frequency (Hz) * 100 .
Read moreHow many messages per day can LoRaWAN transmit?
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 .
Read moreWhat is LoRaWAN duty cycle?
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
Read moreWhat is duty cycle in IoT?
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%.
Read moreWhat is difference between LoRa and LoRaWAN?
LoRa is the physical layer or modulation technique used for long-range, low-power communications links. LoRaWAN is a communication protocol and network architecture that sits on top of the LoRa physical layer.

The iM881A-M is a compact, low power, bidirectional radio module for the 868 MHz frequency band using Semtech’s LoRa® modulation technology. It has been specifically designed for battery driven devices.
Read moreWhat are LoRaWAN channels?
LoRaWAN defines 64, 125 kHz channels from 902.3 to 914.9 MHz increments . There are an additional eight 500 KHz uplink channels in 1.6 MHz increments from 903 MHz to 914 MHz. The eight downlink channels are 500 kHz wide starting from 923.3 MHz to 927.5 MHz. The maximum output power for North America is +30 dBM.
