How to calculate Air on time for my data

hey I am using Rn2483 as end device and my payload size is 30bytes so home much will it take for air on time, is there any calculation charts please share with me, thanks in advance.

If you expand the payload coming into your TTN Application Data window - it has estimated Airtime used if that’s of any help

This tool is reasonable;

Payload length is 13 bytes for the LoRaWAN header plus your actual sent data length.

my payload size is 30bytes

Hey, this question has been asked and answered before. Search the forum to find the answers.

> my payload size is 30bytes

Yes, you already told us that.
