On 14th of June 2018 we hit above 42[km] of transmission from 2[m] above the ground
We hit the record by transmitting an unconfirmed packet using our LoRaWAN tester/tracker (which is still under development) in a car on the move with antenna mounted on its roof and pointing straight up.
Our transmission took place on a S5 road near Zmigrod city from where we were lucky to reach one of the Wroclaw's gateway.
