What positions for 5G and other wireless technologies in the industrial world?

The industry is changing, digitalizing, let’s call it the industry of the future or industry 4.0, it is increasingly integrating data into decision-making. If data has been driving the industry for a long time, we are now talking about another scale, that of massive data, on which it is possible to make faster, more efficient, more relevant decisions with impactful effects.

The quality and performance of the decision is directly related to the diversity and quantity of data processed for decision making. The industry already produces large volumes of data from production processes which already allow a strong creation of value using industry 4.0 solutions. The capture of industrial data then develops in its diversity component to pass a new stage, bringing a look upstream and ahead of the production chain.

This data collection is made possible through new communication technologies such as 5G, but not only. After having experienced the media campaigns on the impact of 5G in the industry, and elsewhere, at the beginning of 2021, I will try to present where to position this technology by its singularities.

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?

COTX-X3 helium miner review

After reviewing different Helium miner like RAK, Sensecap, Kerlink, Nebra… now comes the Cotx-X3 miner. This miner has a long story and a bad reputation, due to something not really clean the maker did with the first units.

This is not related to the hardware quality and I’ve been happy to buy some of them for reviewing it. This miner is a full miner, based on a standard design using a Raspberry Pi 4. It has the particularity of having a front screen and an audio jack ! Don’t laughs, the reason is simple, this device has a different usage before becoming an helium miner.

Deploying Helium-ETL instance with API

Helium blockchain ETL is basically a copy of the Helium Blockchain into a database. That way you can query the helium blockchain history to build apps like monitoring, tax management…

The Helium blockchain API project is connected to the Helium ETL to get an easy access to these data.

I’m currently building a tool to monitor and alarm a fleet of hotspots (stay tuned) and it currently uses the Helium API (api.helium.io). But helium APIs are a bit overloaded and not made to support high rate querying from each of the application any member of the community is developing. So I’ve been decided to make my own instance of ETL and API for my own purpose. This is the experience I’ll describe in this blog post:

Helium solar hotspot (Data-Only) 2021 update

Posted on by

In a previous blog post about 18 month ago, I designed my first Low Cost LoRaWAN Solar Gateway. This year, I did some updates to create a new version to support Helium Data-Only Hotspot (basically it works for any LoRaWAN networks like TheThingsNetwork).

In this version, I’m using a RAK wisegate Lite gateway, it is a bit more power consuming than the TTIG but can work on any LoRaWAN network. I’ve also changed the outdoor enclosure to get a larger and single battery.

You will also see that I’ve been updated the monitoring dashboard to get something better and free of charge. Two of them are in production. One is already deployed as an upgrade of the 1st one and the second one is in the testing phase. The First version has been on the field for more than a year. It has been offline about 10 days during that year, due to the weather conditions. This is a service level of 98,29% from its start until now. With the larger battery I’m expecting to resolve some of the small service interruption I’ve issued during last winter.

Helium Kerlink Miner iFemToCell

Kerlink Helium Miner iFemToCell

Kerlink is a LoRaWan hardware player since the first ages of this technology. This French company has equipped most of the operator’s network and is used to propose high quality industrial products.

The iFemToCell is not a new product. It exists since a couple of years and I already tested the IFemToCell 4 years ago. Recently the company has created a Helium edition we are going to review in this blog post.

This is an interesting device as it is a kind of hybrid between a light miner and a full miner. Even if the Kerlink platform is powerful, it is far away the power of a raspberry Pi and certain operations like consensus group can’t be performed. As this is now delegated to Validator, this difference have no impact on rewards. In another hand, this device is consuming less power and it is possible to power it with sun more easily. This is quite interesting.

Let see what is this device and what is specific during its deployment.

Migrate any LoRaWAN gateway to helium network as a Data-Only hotspot

Posted on by

Migrating existing LoRaWAN network to Helium or joining Helium for new deployment is accessing to the world largest LoRaWAN network and enable your devices to be deployed in the large covered zone. By doing this you extends the community network and as a counter part getting benefit on future data transfer and immediately get an access to the low cost ecosystem (data transfer, network server, high redundancy network…)

In a previous post I explained how to configure a RAK Wisgate as a Helium Data-Only hotspot. In a such situation your LoRaWAN gateway becomes a hotspot relaying the Helium traffic and getting some little rewards for the data transfer. The more important is to extend the coverage. This way of doing is good but I’ve got some issues on the field: The data transfer from the hotspot to the blockchain (even if just the state channels) is high and the software, currently in alpha, is not totally stable. When deploying a gateway is isolated area to provide new coverage, honestly, these two issues are blocking points.

The second important consideration is the existing gateways, already deployed on the field: they are currently used for private networks. They have been deployed some years ago and are not in the compatibility list of Helium hardware. Even if they are, deploying a new software on them, remotely can be a problem.

For these different reasons, I’ve been investigating a different approach by creating centrally hosted hotspots connected to different LoRaWAN gateways through the legacy Semtech protocol. This is what we are going to detail on this blog-post.

First IoT frame sent to space with Kineis devkit

The Kineis IoT solution is an IoT network based on satellite’s communications. Thank to it, a device can communicate from any point of Earth with a single technology. Kineis is using an existing fleet of Argos satellites launched during the last 40 years and is already commercially available. This fleet will grow fast in the next two years to offer a communication window up to 4 times per hour.

In this blog post, I’m going to detail my first experience with Kineis for sending frames through the satellites of the fleet. I’ve been using a KIM Arduino Devkit. The on-boarding is quite fast, let’s see this!
