Wingbits, The DePIN FlightRadar24, ADS-B setup review

Wingbit is a new DePIN blockchain whose goal is to collect ADS-B information provided by aircraft in flight to enable precise tracking, similar to what we know from FlightRadar24, but with a more massive, dense, and global approach. The underlying business model is the resale of this information to companies interested in exploiting it. It remains to be seen how large the demand for this will be in the long term.

However, this project is quite engaging, centered around a topic that resonates with many people, even outside the blockchain and geek spheres. Since it involves radio reception, the choice of hardware is an important consideration when starting the project. As a result, I conducted a small benchmark of various easily accessible equipment to design an efficient, low-cost receiver.

This article will interest anyone who wants to receive aircraft information (ADS-B), including for other projects, as Wingbit has just closed the possibility of building your own receiver.

The Hidden Side of LoRa

While I was working on a blog post about Meshtastic (which will be online soon), I started questioning the time on air in a non-LoRaWAN context, where the online simulators I usually use did not work. This led me to investigate the LoRa frame format (not LoRaWAN, just LoRa, the underlying layer), and to confront the “sync word”, the functioning of a chirp… a whole range of concepts for which I expected to find abundant documentation. After all, in the LoRaWAN world, the open nature of the technology has been emphasized since its inception. However, after quite a bit of research, I still remain somewhat uncertain about the basic workings of LoRa, which at the very least calls for a blog post to compile the information I have found.

I invite those with a solid understanding of the subject to enrich this post with comments, and I will incorporate the key elements accordingly.

Evolution of Usage on the Helium IoT Network

In an article written in 2022, following an unwarranted and poorly executed attack that reduced the value of the Helium network to the nascent consumption of data, erroneously overvalued at $6600, I began monitoring the usage of the network over the months.

To give some context, Helium is a DAO governing the operation of several networks: LoRaWan (IoT), CBRS (4/5G), and WiFi. A DAO is a distributed organization using blockchain to govern its operational processes. This project is one of the pioneers of what we now call DePIN (Decentralized Physical Infrastructure Networks), which bridge the virtual world of blockchain with the physical world around us and generally translate into service offerings consumable in the traditional economic circuit, competing with equivalent services in the traditional economy.

Helium is the largest deployed LoRaWan network in the world. It is used for roaming by numerous telecom operator networks and natively by many companies deploying fleets of connected objects. For my part, since 2021, I have been the first to provide commercial and open access to individuals and businesses to this network to connect their objects, through the service Helium IoT Console delivered by IngeniousThings. For this reason, I pay particular attention to monitoring usage on the IoT network.

IoT Antenna matching with Atyune

Recurrent step when making an IoT device, the antenna matching is a key activity to get the right radio performance for your device. You radio strip and antenna must be tuned to match a 50 Ohm impedance. For doing this I’m using a miniVNA Tiny Vector Network Analyzer (until a switch to my Rigol Spectrum Analyzer) as described on the previously linked post.

The impact of a correct antenna matching has been addressed in an old post on this blog also.

Currently, to tune my antennas, I’m also using the Atyune tool. This tool is free and really good to make the tuning but also to get a better understanding of what you are doing. Let’s see how to proceed.

Sigfox Radio Signal Analyzer

Sigfox just released publicly its Radio Signal Analyzer tool. This is a tool for the device & module maker to prepare the P1 certification : basically it checks the radio signal shape, power… and tell you if you are following the requirements.

The tool have to be used with the SIGFOX SDR dongle provided with the SNEK tool.

The software solution can be downloaded here : https://support.sigfox.com/downloads/sigfoxradiosignalanalyzer.iso

Learn about Sigfox and LoRa radio technologies

This post is a VLOG entry, as usual in French, you will find the english text version in the next part of the post.

Basically, I’m explaining how the two LPWAN technologies : Sigfox and LoRa use the radio frequency to communicate with a low power consumption in a wide area environment.

In this video you will find a mix of demonstration with voice to highlight how it works with day-to-day life example and spectrum capture of both technology to visualize how it looks like.
