One of the big challenges in any IoT project is connectivity. In a few proofs of concept and prototype projects I have worked on the choices have basically come down to either Wifi or 3G/4G connections. Both are ubiquitous and have their place, but both also have significant drawbacks that hinder deployment. Wifi usually requires access codes, has crap range, chews up battery and has FAR more bandwidth than most IoT projects really need. 3G/4G means a subscription or some kind of data plan and most carriers aren’t exactly easy to work with. While platforms like Particle make this easier, it is still relatively expensive to send data and I’d like more choice in which embedded platform to use. Are there any good alternatives?
Turns out there are, and one alternative in particular is appealing for the kind of open IoT projects that will drive us toward the future. LoRaWAN is a Low Power Wide Area Network (LPWAN) specification governed by an open, non-profit organization that aims to drive adoption and guarantee interoperability. With members such as Cisco, IBM and Semtech and an experienced board consisting of senior leaders from many of these same companies and others, the LoRa Alliance is well positioned to make this happen. So that’s one possible standard but how does this enable an open IoT network? How does it solve the problems laid out earlier and make some kinds of IoT projects easier (or possible at all)?
Enter The Things Network (TTN). The mission of The Things Network is to create a crowdsourced global LoRaWAN network to foster innovation in much the same way as the early days of the Internet. By deploying a free, open LPWAN, The Things Network hopes to enable innovators to build and deploy new IoT technologies that can change our communities. That’s a mission I can get behind!

Our team seeks to built a Things Network community in the Birmingham, Alabama area. We have already started reaching out to people across our metro in analytics, RF engineering, embedded systems, software development, entrepreneurship, community engagement / advocacy and government with the goal of building a consortium of local organizations to support a free and open IoT network. Our vision is to build the open and transparent infrastructure required to support the future of smart cities. Birmingham is a great place to do this. The city center is relatively small so establishing full coverage should be achievable. We have other smart cities initiatives in the works, including some things funded by an IBM Smarter Cities Challenge grant. We have an active and growing technology community anchored by such institutions as the Innovation Depot, local groups like TechBirmingham and maker spaces like Red Mountain Makers. We have active civic organizations with goals across the public sphere from economic development to air quality. We have a can-do spirit and our eyes aimed firmly toward the future while being well aware of our past.
Assuming we can get a larger team assembled and this network launched, what do we plan to do with it? A lot of that will come down to the people that join this effort and bring their own ideas to the table. Initially the first few gateways will be launched in support of an air quality monitoring program using a series of low cost monitors deployed within the city. Ideally this will expand quickly to other uses, even if those are just proofs of concept. I, for one, plan to install a simple sensor system to tell me when the parking spaces in front of my condo building are available. I hope others adopt this platform to explore their own awesome ideas and those ideas go on to inspire our city to become a leader in digital transformation.
I hope you will join us at the Birmingham Things Network Community and help us build the future one node at a time.
