We're iFroglab and we did a cool thing of LoRa,Regarding to LoRa alliance has publish News and released such solution of IOT.
its good product can be extend for WiFI/BTLE using distance for such RF technical. (e.g can be extend to 2Km)
but,the LoRa gateway is quite expensive and can't be accepted.(around $1600-$2100)
therefore,we did a LoRa dongle that can be solved this problem if you want to design LoRa topology;
we have LoRa module that can connection with LoRa gateway(Raspberry Pi+LoRa dongle).
yes.,we can plug in a LoRa dongle on your raspberry PI that running our sample code then it will become to LoRa gateway(Low cost).
if you have interest to see this,Welcome to Our booth #51234 in Eureka Park(7th Jan 2017) of CES show.
we have dedicate Sales and engineer will explain more about this.
