LoRa is a low power long range radio data transmission technology. LoRaWAN is a wide area network protocol on top of LoRa, that makes it easy to hook up lots of wireless, battery powered devices to the internet or to your personal server. We will introduce you to LoRaWAN, tell you what it can be used for, and how it works.
With “the things network” there exists an open source community that aims at creating a global network for LoRaWAN devices. You can use it to have your own technical creations reach your server at home from wherever there is a gateway. You can set up your own gateways to help build that network and share the coverage created by you with the community.
We are working with this technology on a daily basis at our jobs (at Lobaro GmbH [1], a small company creating industrial IoT solutions), and find that it has high potential in many geek/hobby/maker projects. With "the things network" [2] there exists a community based open source initiative for making it available (think "freifunk" for IoT), but still there is not much knowledge about it in the scene. It's a cool technology that people should know about!
Our introductions will be centred around Arduino based hardware, which is what most are familiar with.
We will also have a LoRaWAN TTN Gateway at our assembly (which is Deep Cyber [3]) along with some LoRaWAN devices, so that people who get interested by the talk and want to try out how it feels to work with the technology can come to our assembly and have a go at it.
We are aware that there has been a talk about LoRa at 33C3 [4], but that had a totally different scope than ours. They focused on the modulation and how bits are physically transmitted. We want to talk about LoRaWAN, which is build on top of LoRa, and which provides an affordable and easy to use way of data transmission.
