@lupyuen it's time like these when I'm grateful for the Internet. 🙂

@mishari @lupyuen I wouldn't know... You can probably look up attenuation numbers for various types of foliage and figure out an estimated reach. OR, do what I did; test it. Put up a gateway, and drop N sensors (of any type) in "nature" at height where you expect them to be later, and monitor for a few days, possibly move them around a lot and plot the RSSI and SNR at each of these locations.

@niclas @lupyuen how well does Lora work through forest cover?

@lupyuen Sure, but students should get the school to invest $150-250 (Dragino LG308 for instance) in a LoraWAN gateway. And hobbyist could then possibly rely on schools.

@lupyuen I work quite a lot with LoraWAN, to read room temperature data. It should be understood that if you need coverage, you install gateways yourself... Otherwise, your devices/users may be without coverage without notice.
