Does this provide a bare IP connection or is it just for MQTT channels back to your servers? I can't tell if that's "the" method of communication or just a helpful thing that you're offering. Basically, is this something that I would be able to use directly with my company's CoAP APIs?

The protocol speaks LoRaWAN, which isn't IP. The data will get sent via a distributed network, over IP (using MQTT), to a server of your choice. This application server (run by you or someone else) can then store the data, have a REST API endpoint, MQTT channel, or whatever service that runs there.

Anyone know what frequency bands these are being deployed in in the US? I am assuming they using the 902-928Mhz ISM license free band.

Licensed frequencies would make this significantly more involved to deploy in the US.

915 MHz

How can we get this in Victoria, BC, Canada? Anybody want to team up?

Two questions: 1) are there technical restrictions for using this mesh network with remote aerial sensors, i.e. does it hurt badly when nodes move? 2) how well would it perform indoors in manufacturing plants? I'm thinking of low-cost adhoc industrial IoT prototyping.

Support The Things Network. They are not only supplying easy to activate hardware, they are hard at work at an excellent architecture ( http://forum.thethingsnetwork.org/t/request-for-comments-net... ) and a clean, easy to use integration framework.

it would be so cool to just fiddle with IoT sensors without worrying about a nearby wifi hotspot with access. Just using the Things network as a free and open road is a beautiful idea.

And I have gotten my base IoT node down to about 2.50$. How?

Arduino Nano ($1.80) nRF24L01+ (0.63$)

Both from Aliexpress. Combine it with MySensors library and off you go.

For secure connections, use the USB-serial gateway, change the default channel, turn on encryption as well as signing support.

I use Node-red to get the data and do stuff with it.

According to the spec [1] it's for both mobile and fixed devices:

"LoRaWAN™ network protocol which is optimized for battery- powered end-devices that may be either mobile or mounted at a fixed location. "

I spoke with one associated with the lora alliance today and 1) yes, up to about 300 km/h, and 2) they perform well up to 20m underground in cities if gateways are placed every 500-1000m.
