What is Amazon sidewalk?

As usual, I love read what traditional and “tech” press can write about LPWAn technologies. That’s always a pleasure to read such amount of bullshit condensed is a maximum of 10-15 lines. They are directly copied and paste from a press release. The Author added value is a custom and totally wrong clickbait title.

As part of many, the one making me starting this post is from “Le monde informatique”. It is supposed to be a serous source. The title was “sidewalk a threat for LoRa and Sigfox on IoT”.

Just to let you know guys… Sidewalk is just a new Zigbee !

So let see what is really Amazon sidewalk, what are the strength and weakness of this solution

I held the first $1 Sigfox IoT device !

This was 2 years ago during the first Sigfox connect event: Christophe Fourtet was on stage opening a letter and this action was firing a Sigfox message. He was announcing Admiral Ivory service. He was announcing $0.20 solution able to communicate on the Sigfox network. Since this date, the Admiral Ivory service has just been a strategic vision proposed by Sigfox for a future low cost IoT, far from the device maker day to day reality. Far from the minimum $10-$15 devices we currently produce coming with its $2-$5 yearly subscription fee.

Could we imagine, this two years old vision will be the next semester reality ?

Being in relation with the Sigfox lab, I’m back with some really good news about making this vision becoming a reality, let see how it is going to be possible.

MeteoHelix, Sigfox weather station made by Barani Design Tech.

BARANI Design Technology has contacted me to test their weather station product MeteoHelix IoT pro. This is a Sigfox weather station but they also have LoRaWan versions. It is also the first personal weather station class product to meet the World Meteorological Organizations (WMO) measurement accuracy guidelines. So it can be used by scientific and professionals according to its designer. Thanks to LPWAn technologies, it can be deployed anywhere. No power / communication constraints.

I like this kind of product because they are really interesting use cases for LPWAn technologies and useful for agricultural environment. I see a part of my family working in the agricultural domain taking some manual notes about rain daily taken at one point. In 2019 it’s so easy to get graph from a cloud platform and have multiple device for the multiple fields you work on. Sounds like a revolution but it have a price 600€ including communication !

LPWAN is not red ocean market

LPWAN stands for Low Power Wide Area Networks. These technologies are the heart of the innovative IoT technologies. They are allowing sensors / devices to work and communicate for years with really small power requirements. They are enabling long range communication, allowing low costs networks. The first coming on the market was Sigfox with a commercial offer in 2013. After that, a first country-wide LoRaWan public network was deployed in 2016. 3GPP technologies, LTE-M and NB-IoT are completing the panel of solutions with large deployments starting in years 2017-2018.

All along the technology emergence journey, the most frequent question was to find the one going to eat the others. Regarding the market size and the involved money, the communication strategy for the telecoms industry was to consider it and make it a red ocean. The consequences on adoption were not without delaying the customer projects and the IoT market growth.

Blue Ocean strategy is coming from a book written by W. Chan Kim and Renée Mauborgne. Basically it’s about the way you build your business. In red ocean (fishes are fighting each others and blood makes the color) you design your product for targeting the exact same use-cases and clients than competition. You have a frontal competition. In a blue ocean (peaceful) you design your product’s strength based on competition weakness. You create a complementary product on the market. You make different customers satisfied.

Six years from now the first networks was opened. Now that all the technological solutions are proven, I can clearly confirm a blue ocean for all these LPWAN technologies. Actors should switch to blue ocean strategy to accelerate #IoT business and accelerate profit acquisition.

How to transfer pictures over Sigfox network ?

Yesterday in a communication around Securitas Direct deal a small phrase has waked up all the Sigfox community:

Announcing in a certain way the arrival of 600Bps support for Europe (this is already the North American standard speed) to support the picture transfer over the LPWAn network. That said, even at 600Bps it’s a bit complex to transfer a picture… let’s see what we can do with this:

LIbrenard is out – Open Source Sigfox stack implementation

Sigfox is not publishing its detailed specifications. For this reason different people (like me) are doing reverse engineering. Thank to this activity we are now getting more and more information on how the IoT network communication works. I’ve been the first one to publish the uplink frame in details more than a year ago.

Today, during the 35th edition of CCC Congress, Florian Euchner has published, on Github, the first Open-Source Sigfox stack : LibRenard.

This library allows to transform a Sigfox radio signal into a decoded frame (uplink demodulation). It allows to create a Sigfox radio signal from a decoded frame (downlink modulation).

The LibRenard implementation follows the Open Sigfox Protocol specification also host on Github from Florian. It details the uplink as the downlink communication frames. Making this open specification as the real first Sigfox global protocol specification published.

I really want to congratulate Florian for this excellent work. I hope the stack will be soon enriched with the native Sigfox encryption I’ve just finished to detail, with the associated OOB frames.

The Sigfox APIv2 is out !

In a previous post, I was complaining a bit about the Sigfox API. At this time Sigfox was already working on a new version of the APIs.

Today Sigfox released the API version 2 for managing devices, subscriptions, messages… And this new version based on REST and JSON standards is a really positive rupture compared to the previous one.

More than a new version of the API set it’s also the full deployment of some of the new backend components now accessible by the API deployment. As part of this the 2018 deployed new Group entity, the asynchronous device creation/edition processing and the coming replacement of the callback duplicates to the equivalent with API.

As part of this APIs also some coming features like different level of geolocation precision, payload encryption and many more…

SigfoxConnect disclosed – Sigfox micro gateway

This was the more expected announcement for Sigfox Connect  event: the availability of the micro-gateway: a Sigfox gateway you can buy, own and deploy on your own location.

This was expected to be introduce has it has already been disclosed once FCC certification made it public as it has been noticed by Nestor Ayuso on twitter some days ago.

This model is standard for LoRaWan ecosystem running on private network as on public network. For Sigfox it has always been possible to expend the network but it was a little bit complex because you had to rent the basestation from Sigfox and the basestation itself was an operator equipment: something made for being installed on a roof, not in your office.

Sigfox is now proposing the micro-gateway !
