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.

Make Sigfox works with potatoes, an ultra low power story

Sigfox Connect yearly event is the opportunity for the company to present its vision on IoT technology evolution. As part of the 2019 edition, the company has introduced Ultra-Low-Power Sigfox communication. In this domain, we are talking about micro-watt to send a radio message over the air the Sigfox network will be able to capture on the fly. You can find a lot of different use-cases for a such communication system. Industrial environment sounds to be the primary market but it can also be included in final products. The main interest of ultra-low-power is to not needing battery but harvesting its energy from many sources, up to the existing WiFi network energy captured from the air.

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.

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:
