What is the expected range of this thing? How far can it communicate?

Couple of miles line of sight. But depends on the spreading factor and bandwidth.

  With good line of sight, LoRa can reach hundreds of km with pretty low power. Extremely low throughput, though, but can still be useful.

    I mean, with large enough resources it can bounce off the moon: https://www.satelliteevolution.com/post/world-record-european-scientists-bounced-first-ever-lora-message-off-the-moon https://www.satelliteevolution.com/post/world-record-europea...

    A few miles with a non-directional antenna and a useful data rate.

Line of sight range is huge, current record is a little over 200 km I think, but practical range is much less. TTN Mapper[1] is a map that shows you estimated approximate range of existing public nodes. The guy behind it also has a good video on Youtube about the algorithms used[2]. The Things Network[3] has has their own map. Finally there is Helium that also has a map[4, but I think you have to participate in their crypto thing to use their network.

Also used in (cubesat) satellite communication. More than 1000 km is common. See for example what has been received by this ground station today: https://tinygs.com/station/Pegasus@5256664939 https://tinygs.com/station/Pegasus@5256664939

We use LoRa transmitters/receivers for RC planes and they can easily go tens of kilometers. I've gone 11 km with a tiny, 5mm ceramic antenna on the receiver and 200 mW on the transmitter. It's insane.
