These radios have been available for quite some time, it's the Semtech SX127x line (e.g. SX1276). I was looking into LoRa and other long-range IoT WAN radios about a year ago for a research project. You can get cheap (22 USD) Arduino-compatible development boards here using HopeRF modules, which work great with the RadioHead library: http://www.anarduino.com/miniwireless/ http://www.anarduino.com/miniwireless/ http://www.airspayce.com/mikem/arduino/RadioHead/ http://www.airspayce.com/mikem/arduino/RadioHead/ (I have no affiliation with the websites.)
