This month is about Sigfox Connect event:

As usual you have 2 version of the podcast in French and English but that time, the English version is different. I’ve record a round table with some of the Sigfox Ambassadors (Jose, Marc and Claudio). Thank you so much for joining me in this episode friends !

The other Sigfox Connect news

During Sigfox Connect 2019 we had different announcement like ultra-low power devices and ultra-low-cost IoT devices with a BOM under a single $. There are the main announcement in my point of view but we have also had much more coming with updates on previously seen technologies.

At first Sigfox announced the ability to deploy a private network, we are going to see what it could means as the details have not yet been given. Next I’ve got update on satellites connectivity and bubble service announced last year.

All about the Sigfox Connect button

As a gift to the participants of 2019 Connect forum, Sigfox has offered a connected button. This button is the first official device based on the ultra-low cost technology detailed in my previous post about $1 Iot. This device is based on a single SoC, a CMT2189C chip from CMOSTEK. This chip usually made for garage door remote controller is offering a low-cost solution ($0,25) with a MCU+Radio solution, compatible with Sigfox.

In this post I’ll detail what are the components of this solution and the real price you can achieve for a such device to verify the low cost promise.

Sigfox published the reference design for this type of IoT devices, including the button elements. Where writing this post, I did not add a chance yet to read the final version of the document and the estimate is based on reverse engineering of a prototype I’ve got a month ago. The reference design can be obtained from build.sigfox.com.

Make your own $1 Sigfox IoT device

Previously in my blog post “I held the first $1 Sigfox device“, I’ve explained how the Sigfox network will soon accept some really low cost Radio MCU chip on its network. One of them is the cmostek CMT2189C MCU. It has a cost around $0.25 and has it own integrated radio compatible to Sigfox. This device has initially been made to support garage door remote and it has a lot of limitation. However, you can imagine many application. This post details the first steps to get a development environment ready. And this should save some of your time by going directly to the right way.

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.

Sigfox monarch

Sigfox Monarch service is a free global service allowing to determine the zone where a device is located.

By zone location I mean RC (Radio Configuration zone). It basically defines the European Zone (RC1) or the North American Zone (RC2)…

Thank to this technology a world-wide device, having no GPS to get its location, is able to determine its radio configuration and the associated frequencies to use for transmissions.

This service is covering most of the airports and ports around the world to support the existing customer use-cases like Louis-Vuiton tracker and Safecube container tracking.

It would be great if this service could, in the future, be also used to broadcast/multicast information to devices. It could be used to get time from the network and later be also used to transport custom data to the group of devices. But currently it does not transport any data.

In this post I propose to detail the Monarch technology and then, in a second post to see how to use it with the first released devkit from Unabiz supporting Sigfox Monarch.

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.
