Recently, on Linkedin, I reacted on a publication that is looking like this one. I’m used to react on LPWAN publication when they are comparing technologies as this one. Comparing apples with eggs and usually meaningless. This one was particularly interesting me because, most of the content is non-sense and scientifically subject to discussion. I’ll detail it in this blog post.
It’s really interesting the way it has been made and also the way the author publish it, react on it on Linkedin and what objectif is serves : capture people in a world where the truth is adapted to make you think only one of the technologies serves all the possible use-cases and all the others are the worst existing. The purpose is to sell you some books and services. This is really looking like the way flat hearth believers, radio waves danger believers and other groups do to find adepts and to sell goods to them. It’s really funny to see and discuss.
As the Author of the original document above considers his slide as “art” you can’t use, copy, cut (even if he published it online on social network) I have made my own one and simplify it to not entering in the expecting promotion this guy is looking for and to troll on the social networks. The curve you see are the exact copy of the original one. These data seems to come from a university work and are needed to be debunked. I just not mention the highlighted technologies other than Sigfox and LoRaWan because they are the one the slide tries to discredit and we will see how that’s wrong.
I do not identify the original author of that “artistic work” because I consider the scientific aspect of that “work” so bad that it discredit too much this person, its student and the associated university, that I don’t want to discredit these people directly. As I did on Linked-in but the author has immediately identify itself to start its promotion.
As I did not had access to the full study, sources of these graph, I can’t tell if the initial work quality that as been done is bad or if the context of the experience is explained. May be the original document explains different conclusions, so I’ll try to not judge too much the original work that has been done. I’ll judge what the author of the slide gave to us, as a single slide with pseudo-scientific information and a fake conclusion. Apparently, if you are ready to pay for the book / register… , you can get more details, thing I do not want to do to feed the troll.
Since yesterday, the microcosm of the IoT has been in turmoil, Sigfox, the Toulouse company, pioneer of the Internet of Objects, the one which had carried out remarkable fundraising for France: 100M then 150M is placed in receivership. But is it really a surprise? Is this the end of this technology?
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.
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.
In a previous post I’ve been presented an idea for creating a kind of satellite solution for watching over pandemic progress over the world using low cost connected thermometers. You can get the details of this idea in my blog post “What IoT can propose against Pandemic“. Basically the proposal is to add an ultra low cost IoT communication feature into a thermometer and report the information when an over heat has been detected. That way we could be able to determine the level of pandemic and its geographical progression over time. So I won’t detail all the business model and financing proposal, you will find all of this in my previous post.
The second step is now to make a prototype of a such device to show how too make it possible. For making this I’ve selected the thermometer you see on the picture above and decided to hack it and connect it to Sigfox network. This thermometer comes from Amazon and cost 14€ but is really like all low cost thermometer we can find.
Ten month ago, I was starting investigating the Ultra Low Cost Iot thanks to Sigfox given access to the experimentation they made in this area. The Ultra Low Cost IoT is defined by manufactured devices under or near the cost of $1.
Such level of price are enabling scalable deployment of devices and mass data capture, more than it has ever been able to made. And basically, it is not a question of device cost, it is a question of scalable use-cases where the higher device cost where a business model killer.
This is basically reducing the price of devices by a factor of 5x to 10x. No miracle, this is also reducing the device capabilities and concerns different use-cases than the one previously designed. In another word, Low Cost IoT is not classical IoT for a lower price, it’s a new IoT area where we find new use-cases, new business model and more generally is source of innovation.
I’ve recently made a post on how to make a pandemic alarming system based on low cost connected thermometers. This post was more about the organization model and business model than the technological solution and implementation. So I also wanted to continue to investigate the connected thermometer solution, mainly for the fun. As I’ve been sponsored by digitspace.com for some free hardware, it has been the opportunity for testing contact-less thermometers module.
The design I’m going to propose in this post will not apply to the low-cost connected thermometers as the technology I’m going to use is far more expensive to the one I proposed in my previous post.
That said, this design can be useful for companies, public site or free access thermometer booth anyone would like to design at low cost.
