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.
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.
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!
Sensecap is one of the Helium miner official hardware. This one has been made in collaboration with Seeed a big hardware maker and provider.
The production and distribution has started on July 2021 and that solution is really promising to help solving the shortage issues currently seen in the Helium market. As a reminder, Helium growth has been from 15.000 hotspots to 100,000 hotspot in less than 8 months. In a period of global shortage in semi-conductor market it is quite challenging for the hardware provider and the current estimates are about 200,000 – 400,000 back orders.
Sensecap coming batch of 10,000 and more units are really welcome, with the promise of selling produced only devices instead of pre-orders. It sounds like a good choice now days.
So let’s review the technical part of the Sensecap miner.
Even if you think it is the first time you heard about Kineis, you are basically wrong in some ways ! This company is a recent “Startup”, existing since June 2019 but for real, they are managing an IoT offer based on top the famous and quite experienced Argos system, started in 1978 and now operating more the 22.000 devices running application like animal tracking, ocean safety and many scientific programs. The service is running over the 8 satellites currently in orbit, making Kineis the most advanced satellite IoT solution commercially available as of today.
Thanks to the polar orbit of the satellites, the whole earth is covered, no white zone, no blind spots from pole to pole, ocean to desert, device are communicating from everywhere, autonomously.
This blog post is the first of a series made with the help of Kineis to introduce you the technology and my experience with it. As usual, there is no sponsoring for these blog posts but a close work with Kineis as the offer is only open to business companies currently.
Companies like Exotic Systems, Arribada or Advanced Tracking, have already started to make products using Kineis network for asset tracking applications mainly.
When making IoT development, you need to debug on the Field. I’ve been using some serial logger to store information and analyze them after (I’ll post something about it once a day). But sometime you want to watch it in real time. So you need a small terminal you can easily transport with you. Smartphone could be cool and I’m sure we can hack something fun with a BLE connectivity. By the way, what I had in stock for doing a such thing was a Wio Terminal from Seeed.
This device is an Arduino compatible solution including a LCD screen 320×200, some interesting embedded sensors and a lot of IO to play with. The only bad point for me and the design I want to do is the absence of internal battery so you need to power it a different way.
What I need is just a Serial line to print on the LCD screen all what my IoT device want to share. Let see how I did make it.
