For his entry into the 2019 Hackaday Prize, [Marin Vukosav] is working on an ambitious project to create a small GPS tracking device which utilizes Narrowband IoT (NB-IoT) for long range communications. Rather than using a GSM modem which would suck the batteries dry in short order, NB-IoT can theoretically maintain a connection within a 10 to 15 kilometer range while keeping the energy consumption low enough that the tracker could go up to a year before needing to be recharged.
At this point, the hardware is still in the proof of concept phase. [Marin] is using an Arduino with a GPS shield and a SIM7000 NB-IoT module to experiment with the concept, but ultimately says he wants to shrink the hardware down to the point it could fit inside of a bike light. Looking even farther ahead, he’d like to make deals with bike manufacturers so the module could be integrated into the frame itself, where a thief wouldn’t be able to access it at all.
Of course, nothing says this technology has to be limited to bikes. If [Marin] can get it small enough, and reach even half of his goal battery life, he’d have a very compelling product on his hands. Who wouldn’t want to add something like this to their long-range drone in case it gets lost?
There’s still a long way to go on this project, and it’s not all hardware. [Marin] will also have to create the software side of things, a site where you can register your tracker and be able to view its near real-time position on the map. It’s a lot of work, especially if you’re planning on turning it into a commercial product, and we’re very interested to follow along and see where the project goes throughout the year.
