@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.

A friend suggested 20 km coverage: https://qoto.org/@lupyuen/106946495191884623
Anyone knows how far a #LoRa Base Station can cover ... In the tropical forests of Thailand? 🙏
Wild Elephant Tracking in Thailand ... With #LoRa / The Things Network? 🤔

@niclas @lupyuen working on a system to detect elephants to reduce surprise encounters in the wild. Feel free to star and contribute https://github.com/elephant-detection/research

@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.
I hope you have good #TheThingsNetwork Wireless Coverage in your area ...Coverage in Singapore is so spotty 😭
We have just transmitted data from #PineDio Stack BL604 to #TheThingsNetwork Cloud over LoRa ... For Free! (Assuming we have The Things Network coverage)
#TheThingsNetwork receives the data transmitted by #PineDio Stack BL604 thru our LoRaWAN Firmware yay! 🎉
Now we send data from #PineDio Stack BL604 to #TheThingsNetwork ... Here are the commands for our LoRaWAN Firmware
#PineDio Stack BL604 successfully joins #TheThingsNetwork thru our LoRaWAN Firmware yay! 🎉
To join #PineDio Stack BL604 to #TheThingsNetwork, boot the LoRaWAN Firmware and enter these commands
From our #TheThingsNetwork Device, copy the AppEUI, DevEUI and AppKey ... We'll enter these into the LoRaWAN Firmware for #PineDio Stack

Why set LoRaWAN Version to "1.0.2 Rev B"? Because #TheThingsNetwork has been upgraded recently ... Setting the incorrect LoRaWAN Version will cause Message Integrity Code errors! (I tried)

First look at Microchip PolarFire SoC FPGA Icicle #RISCV board
Let #TheThingsNetwork generate the Security Keys for our LoRaWAN End Device
