It was a good weekend. At least for me and CDEbyte E45-TTL-100 868MHz LoRa serial wireless modules based on SX1276. Why? Since weather was nice and looks like those modules are way better than datasheet specifies. Specs states: 3km in open space. And I've proven almost twice that much range! Last Friday I've placed one E45-TTL-100 with stock antenna on my balcony, took second with me and went for a car ride.

E45-TTL-100 LoRa 868MHz range test results

Area around my home is full of small hills and copses, so most of the time something was blocking the line between transmitter and receiver. But every time I was high enough, I was getting clear signal without any packets lost. At the furthest point of my trip I was 5.7km from the transmitter, inside a car and a copse was between me and TX module. That means no line-of-sight and as a result I'm pretty, pretty sure E45-TTL-100 should be able to work on much higher range that that. I only have to find a good place to test it.
