    One technology that’s become recently available is LoRa, which is a ISM (900 MHz) band system that’s optimized for data transmission. More details at https://www.lora-alliance.org/ but PCB’s with LoRa radios on them are available from Tindie.com at reasonable pricing (sub $20 ish). It looks like these would require a base station to complete a network, but they claim 5 to 10 km of coverage, which might be sufficient for may applications. I’m not affiliated with them, I just find the technology interesting.
