Did we have a Sigfox Connect in 2020 ?

Sigfox Connect is usually one of the MAIN EVENT for the LPWAN community as the technical solutions provided by Sigfox were, in the last 5 years, the one presenting disruptive innovations around low power radio communications suporting the IoT revolution. I was usually rushing on my blog to communicate and explain how these innovations could transform our markets…

This year in 2020, I’ve made 5 days before starting to write something because, I see nothing really interesting to tell about this event, at least on the technical side. I could fill many pages on the quality of the event, starting by the backgrounds, the phone ringing in background, even on recorded conferences and the number of conferences about the same topic (supply chain). Christophe Fourtet had a great talk… for Sigfox beginner… and my preferred event’s backgrounds. But what about the yellow texts scrolling ?!? WTF !

So, I could write tons of line on this topic, but let’s try to go to the only and main announcement of this year, nothing technical, something like a company business pivot. Basically, after watching Ludovic conference, I had to refer to the only one online press post to understand what it was about. The morning keynote had some of the elements related to it but honestly I give the same to my IoT students on the first 30 minutes, so for the vision I’ve been a bit disappointed. You can check my IoT slidedeck.

IoT overview 2020 update

Traditional update of my teaching support on IoT. This year I’ve addressed my speak to larger and different audiences. As a consequence I publish a totally renewed slide-deck with 203 slides. I’ve improved the IoT business model description, use-cases and technology area. I also detailed the platform side of the IoT solutions.

Feel free to reuse this content for your own conference and speak. I’m available for conference, talk … let me know.

The full PDF is available on the following link.

First steps with Helium IoT network

Helium is a crowdsourced-crypto-blockchain-Iot network working with LoRaWan. With all these trendy name, for sure they had the key elements to raise a large amount of money. That’s great for the development of this technology.

I’ve decided to write about this IoT network after an interesting talk given at the Zurich IoT meetup today (thank you CoVID-19 for making us the opportunity to reach such event, today online, bad things can get positive sometime).

Helium is a crowdsourced network. It means, like for TheThingsNetwork or Amazon Sidewalk, the infrastructure, at least the gateways part (antennas) are provided by anybody, basically you and me. That way the network deployment costs are really limited and the network have no boundaries.

Compared to TTN, Helium network is “crypto-blockchained” basically, the gateway owner are mining different challenges like registering some network change, proving the location of a gateway, cryptocurrency transactions… For this work, for maintaining the network architecture and relaying the messages, the gateway’s owner are earning HNT (Helium Network Tokens) ($2.24 each today).

Compared to TTN where you make it running for free, just because you are convinced about the sharing economy, Helium base its business model on a promise of getting some money back from your investment the gateways (+energy, communications…).

Helium is an IoT network, a LPWAN for being more precise. It relies on LoRaWan standard protocol & gateways. You need to add an Helium miner software on a backend system to make it running.

So they are looking to Uber-ize the telecom domain, at least this is what they are expecting.

LORIX One LoRaWan gateway review

Yes, I’ve got one of these LoRaWan light saber I was looking for, since a while! For this I really thank you Wifx who helped me to get one. I know this is really unusual for them to work with blogger, so thank you for your trust. So honestly, even if I’ve been sponsored to get the device, I’m really happy to make that gateway test. As I said this gateway is one of my favorite since a while. The reason are a really compact outdoor design. It makes the difference 😉

I did not made a test previously because this have a cost, about 500€, (549CHF) this not much expensive but a bit high regrading my non-profit activity on TheThingsNetwork local deployment.

Now, I’m done telling you my life, we can see what this gateway is proposing !

What IoT can make against pandemics ?

Pandemic prevention and management is an interesting territory for IoT. I’ve seen different projects and solutions made in emergency to help during the Covid-19 crisis like some connected button distributed in hospitals to get assistance for going to toilets. That’s an interesting use case for IoT where you can deploy quickly a solution (20K have been produced in this example) and make it working in an existing environment (an hospital) with no integration complexity with network or other existing infrastructures.

My favorite example is the Us health Weather Map reporting the human temperature sensor information across the USA. I love this use-case because it works on prevention: detecting the rise of the pandemic, show its movement and scale. The current problem is that these data comes from high-end thermometers, using Bluetooth and the number of device is limited. The other problem are the personal information attached to these device.

This is where LPWAN and Sigfox in particular can be used to propose a innovative solution I’m going to detail a bit.

Low-cost outdoor solar powered LoRaWan Gateway

I really love Reece Innovation Solar powered pod product developed by my friend Jose Marcelino. They’ve made a agricultural / industrial autonomous solar powered LoRaWan gateway for a really competitive price. With much more money to extend TheThingsNetwork in my city I would have used a such solution. But as this is just a hobby for me, I’m looking for really low cost solution, something under 500€ per gateway.

My main issue to extend the network is not really to find roof but to find some where I can pass an Ethernet cable and provide the power from it. I have some place where I could deploy new gateway in conduction to be cable-less. The network is not the main issue as most of the time a WiFi network is accessible. Powering is a larger problem to solve. Advantages of outdoor gateway: you have sun available. So, as Reece Innovation did, I decided to make my solar gateway, the main differences are: my will have no LTE communication capability (only WiFi) and it have to cost as less as possible.

Let see what I’ve done
