Until now, all the Helium data-only hotspot I have been tested where DiY devices. They are not really complicated to manage but they are not ready-to-go, so you need to manually on-role them with a wallet and some complex CLI operation for the non-experts. This SenseCAP M2 is the first one I’m testing, ready-to-go or close to be ready-to-go (that does not means it is the only one existing).
As it is a Data-Only hotspot, it means it does not participate to the Proof of Coverage, as a consequence, there is no related rewards for this device. This device only earn the DC (Data Credit) for transferring the communications, so $1 for 100.000 packets. Before getting question, this have no return on invest in a crypto point of view. This has been made to help supporting professional applications on the Helium network.
In some of my previous post, I did talk on Kineis IoT satellite solution. The competition is that area is large and one of the other player is Astrocast. I really thanks them for getting me in the program to explore this technology (and I apology to have been a bit long to start using it).
Astrocast is a Swiss company launching nanosatellites to currently provide Europe, Asia, Africa coverage for IoT. It uses L-Band (1-2 GHz) radio. The transmission period will be 15 minutes once the constellation will be fully deployed. The current constellation is 10 satellites for a target of 100 satellites by 2025.
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?
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.
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!
