The last thing I read on 'LoRa' implied that it needed some kind of base station in order to work... Or am I getting confused?
On a slight tangent, I just took an eQ-3 MAX! wireless radiator valve to bits and discovered it's got a CC1101 chip in it, transmitting at 868Mhz. Looking on eBay there are a whole bunch of modules available with that on too - boasting around 350m range.
Seems it's got a whole load of interesting packet handling stuff on it, including the ability to automatically turn the receiver on every Y ms, and then only wake the MCU up if it gets something. It'd be great for low power stuff.
