CC1101 is another example of modern radio modules. I might not have the receiver sensitivity or LoRa SX1276, but with proper antennas should give more than 1 km of radio transmission. Recently I got a couple of them, so expect some new projects with CC1101 and Arduino.

Now, something that took me some time to find out, so you will not have to: CC1101 pinout:
