Two years since I did not published my IoT slide deck. Here is the new version, now about 345 slides about IoT topics including Sigfox, LoRaWan, Helium and much more. In this edition, you will also find some slide about the digital transformation impact on the society and the environmental impact.
All the slides on this deck can be freely reused for any educational content; Most of them are also used in my different MooC you can fin on my Youtube IoT Channel

The new baby in Kerlink family has arrived, it’s iZeptoCell ! Ok, I’m a bit late to write this blog post and it came alive a couple of months ago. When I say baby, I really mean baby, no due to its age but more related to its size !
This LoRaWan gateway is really small and can take place in any indoor environment looking like a sensor but providing a wide range connectivity for many devices deploy around. This is a really good option to cover a small / medium company floor up to a building.
This gateway exists with an Ethernet connectivity like the one I’m testing and with a Cellular connectivity, something appreciated when corporate IT dislike having devices on the corporate network.

The Dragino LPS8, LoRaWAN gateway is a helium ready device you can add to Helium as a Data-Only. It means it does not participate to PoC but earn HNT for transferring traffic.
It’s not a ready-to-go data-only, so you need to register the hotspot in the helium block-chain on your own but it run the gateway-rs software internally.
This device as been designed for Helium, but not only, it can be connected to TTN or another different network, like a private network. The installation with Helium network is not really complicated but you will need to process some command on a terminal and manipulate wallet-cli.
To save you some time, I do not recommend this hardware, as it suffers from two main issues: poor noise isolation leading to low reception quality, and overheating problems that cause frequent unexpected reboots.

ChirpStack is an open-source LoRaWAN network server that is being use in a coming future with Helium as a replacement of the console. This blog post explains how to install it with the companion solution I’ve built to interact with Helium router.
This blog post requires you to own an OUI.

The Arduino board MKR1310 is the new revision of the MKR1300 board dedicated to LoRaWan. This board is a SAMD21 Arduino board with a Murata ABZ module based on a STM32 with an SX1276 transceiver. Basically a bit outdated and expensive modem now.
After using this board for some teaching project, it’s a good time to make a feedback about it as many things need to be improved on that board to get benefit of it.

This week saw the return of face-to-face of The Things Conference after long years of virtual events. The Things Conference is the major LoRaWAN ecosystem event. Not as commercial as LoRa Alliance event (even if the conference is a source of revenue for TheThingsIndustry), thanks to the presence of most of the guy’s who are doing the IoT.
This edition has interesting weak signals like the presence of a team from Unabiz (previously Sigfox), some Helium bashing at some time, even if most of the attendees have been participating on The People Network.
It’s a conference I can place on the maturity rising, many talk about use-cases, less about technologies. Lots of workshops where we have been able to implement / test advanced technologies like Lacuna Space communications or Semtech low power tracker.
Here are my through from the really great edition of TheThingsConference2022

Some time ago, a twitter thread made the community react about the amount of $6600 of communications consumption on the Helium network. This thread was full of approximations in order to present negatively the growth of the Helium network. But it is also an opportunity to take stock of the development of the use of the network. We will see in this article who operates the Helium decentralized network, what are the current data volumes and what are the associated financial metrics.
In short, we cannot talk about Nova Labs’ revenue with respect to direct communication costs because these costs are associated with different third parties offering the packet routing service. We cannot rely on this cost to estimate an associated business volume because there are many indirect costs as I have already specified in my blog post analyzing the running costs of a Helium router/console. Finally, regarding a long period where gamers found a way to earn a few dollars on the back of Nova Labs, involving many ancillary costs, distorted the data for June. You will understand all this in the rest of the article.

The Helium router (aka console) is the LoRaWan network server. In a previous post I described how to setup a Helium router / console. In this post I will give you some details of what you can see in the grafana monitoring dashboard and this will help you to understand better how the network works to process the LoRaWan packets. We are going to detail what is an offer, a packet and the different monitoring information we can get from the router.
