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.

The Things Indoor Gateway (TTIG)

The Things Indoor Gateway (TTIG) has been announced and distributed during the TheThings conference 2019. Since it was impossible to get some, victim of its success (and the little initial stock). From mid-august it is now possible to get some and I’ve bought one as soon as possible.

The Things Indoor Gateway is a low cost (70€ – 90€), 8 channels (EU868 full gateway), LoRaWan gateway running on TheThingsNetwork. You can’t expect a large coverage with a such solution to be used for city wide network but it will be perfect for covering a large house or a small building where you want to deploy LoRaWan sensors.

IoT Decoded Podcast EP#1

First episode of my IoT podcast. This month is about IoT maket study and how numbers can be bullshit when comes from certain analyst. We also talk about the LoRaWan world distance record.

This first episode is a test, a poor and a bit dirty (or too long) episode for testing podcast concept on my blog. It is going to be a monthly rendez-vous on IoT and especially LPWAn news.

LoRaWan in US915 zone

I’m living in RCZ1 (EU868) area and our zone have some specific rules for using the free radio frequencies like duty-cycle to comply regulation I already shared in the linked post. I was little experienced with the US zone regulations. Thanks to a project made for a North American customer I started working on it and I’ve surprised of the differences and how it impacts the LoRaWan developments.

Yadom Murata CMWX1ZZABZ-091 breakout board under review

Murata CMWX1ZZABZ chip is actually famous for being a powerful LoRaWan multi zone module also able to communicate over Sigfox.

I’ve already published a technical post on Murata CMWX1ZZAB chip in a previous post. You will also find an implementation based on my IoT SDK. Yadom has just released a breakout board ( BRKABZ01) for this chip making it accessible for hackers and for easier prototyping.

This post is going to review this board and demo how to access it really quickly. Are you ready ?

Getting started with ST Murata LoRaWan board

ST Micro-Electronics is providing a development board with a Murata CMWX1ZZABZ-091 chip. This device is a module containing a STM32L0 chip (192Kb of Flash / 20Kb of RAM) associated with a Semtech SX1276 radio chip. This module can be used as a SoC for developing LoRaWan IoT devices. The Semtech chip is also capable of Sigfox. This module is a bit expensive but it is actually the one allowing LoRaWan and Sigfox communication in any of the RCZ zones.
