LoRaWAN is an RF standard for IoT devices to connect to the internet.
Gateway
Research
We decided in the Plenum to buy a LoRaWAN gateway for the space. However, we don't really know kind of gateway to get. Let's figure out what kinds exist today.
Prebuilt
- The Things Gateway [1] - not available yet?
- Kerlink IoT station [2] - can you buy that?
- Microchip LoRa Evaluation kit [3]
- Includes a gateway and two nodes
- RisingHF Gateway RHF2S008 [4] - around 700€ ex. taxes Media:Lora_RisingHF_Prices.pdf
- Product brief Gateway RHF2S008 [xyz]
- Product brief Modem [xyz]
- Product brief Temp/Hum Sensor Node RHF1S001 Media:RHF1S001_Product_Brief.pdf
- AirFy
- [5]
- Supposed to be available sometime in Q4 2016
DIY
- ic880a-gateway
- http://www.instructables.com/id/LoRaWAN-Gateway/
- Single Channel Gateway (not LoRaWAN spec conform, but maybe sufficent for testing?)
SDR
Just some thoughts. The difficult parts to get seem to be the RF modules for a LoRaWAN gateway. How about building one with a SDR? We have a few badges from the last CCCamp at the space, which work like an HackRF...
