LoRa radios are very long-range (multiple miles/km) using small antennas and very low power. In exchange for this, they give up speed; the longest-range LoRa modes operate at only around 300bps. My lorapipe program aims to provide some nice Unixy interfaces to LoRa. See also XBee SX; those radios are similar, but offer hardware meshing and some additional nice properties. I have written quite a bit about LoRa; see my blog series about LoRa.| www.complete.org
