On 9th of April 2018 we hit above 34[km] of line-of-sight transmission
We hit the record by transmitting an unconfirmed packet using our LoRaWAN tester/tracker (which is still under development) held in hand but standing at the bottom of the Sleza hill with antenna pointing straight up.
Our transmission took place from the lower mountain shelter's area (called Schronisko Wiezyca) from where there is a beautiful view in the Wroclaw's direction.
