I dived into what I called narrowband networks for IoT 2011 since there was an obvious need for an infrastructure that didn’t exist. I used to say “think cat, bicycle and smoke detector” to put the finger on the need. Or translated into requirements: low cost and often small and light communication modules, low cost connectivity and very low energy consumptions. The answer to that would be inexpensive infrastructure which is providing primarily heart beats, events and when needed position. The first solution I found was Sigfox and after a training in Toulouse I wrote this post.
There are four key alternatives for LPWAN emerging: Sigfox, LoRa, 6LoWPAN and NB IoT. Each have it’s strengths and weaknesses and it’s likely they all will play a significant role in the rapidly emerging new generation of Internet.
Sigfox is a proprietary solution with national networks built with Sigfox base stations operated by national Sigfox operators using the same back-end system operated by Sigfox. Sigfox has networks in some 30 countries today, with over 8 million connected devices and have a well developed eco system of developers and vendors on the terminal side.
LoRaWAN is a global LPWAN specification created by the LoRa Alliance to drive a single standard for seamless interoperability across the industrys. Networks are built with LoRa Gateways and LoRa Network Servers available from several different vendors. LoRa alliance has some 400 members and continue develop the standard. LoRa could be compared with WiFi since networks can easily be built with one base station covering an area like a campus or square and expanded to cover cities and countries. But there is no common back-end arrangement for roaming, service level agreements etc.
6LoWPAN is a concept originated from the idea that IP, the Internet Protocol, could and should be applied even to the smallest devices, and that low-power devices with limited processing capabilities should be able to participate in the Internet of Things. It’s worked on by an IETF working group. 6LoWPAN is similar to LoRa since networks typically are deployed independently in a campus, city or building with no global back-end service.
NB-IoT is the narrowband bet by the mobile operators. It differs since it is using private spectrum and typically the infrastructure already in place in mobile networks. The initiative has been developed in record time and most mobile operators are planning roll-outs. The first NB IoT networks are expected mid 2017 and we have just started to see modules, developer tools etc. It is also interesting to follow how NB IoT relate to 5G since support for narrowband has become a key part of what is targeted.
Due to the very big interest and potential for narrowband networks there are several other vendors and efforts to address this need.
LPWAN is now the hottest of questions in IoT
since manufacturers, vendors, users, developers, consultants, operators, teachers and journalists all need to understand what it is, the different solutions available, how to develop applications for LPWAN and when to choose which solution. This is why I try to run as many “Get On Top Of LPWAN events
” as I can to ensure Swedish IoT
will remain leading edge.
Finally, I’m glad to let you know that we finally have a Sigfox operator also in Sweden! IoT Sweden
was just announced and have started to roll out their network in larger cities already. They run their launch event at THINGS March 21
if you’re interested.

The telecom industry got a head start in the early days of IoT aka M2M. Ericsson took the lead with the 50B connected devices mantra which translated well into an obvious role for huge operators with millions of connected users and massive investments in wireless networks. And it went without saying that the obvious providers of technology and solutions would be the telecom vendors already in the family. This was a clever and well executed plan by primarily Ericsson since the operators were looking for the next massive growth opportunity after having connected most people and given them data buckets. Operators went for it with one primary caveat – we will not only provide connectivity.
Now, only few years later IoT has gone from a connectivity focused baby to a data centric young adult. IoT is only a new phase of Internet – we’re adding things to people and businesses already connected – which explains the speed of development. From a usage point of view, Internet including IoT and the enabled services and solutions will remain customer focused and very fragmented and the operators will continue working hard to figure out their role beyond connectivity.
Here’s what I would do. The two major challenges for IoT are security and privacy. The smaller one is security since we are used to repair and plug holes as we go, and since we tend to have a very short memory. But privacy is really challenging since nobody knows how the requirements will develop over time. When your data is out you can never get it back why any service will need a solid privacy architecture to cope with future requirements without having to rebuild from scratch. The user must own his or her data and decide who should get hold of it.
But privacy is not only a technical issue why we need trusted partners to help us manage our data. Today most of us trust serious banks to manage our financial data as an example. Our trusted partner needs big muscles to force and enforce proper agreements and obviously have to walk the talk themselves. Operators already manage a lot of our private data and provided they do that well, this is a great position to build the trusted partner role on. The trusted partner role can also be required to build and orchestrate a fair and robust sub-eco system in a specific market like smart homes or connected cars.
So why is privacy of importance anyway? Today most users of internet applications sign up without even reading the agreements. One often hear “I’ve nothing to hide” as the key argument to avoid the hassles of reading and thinking. But with today’s capabilities in data analytics, all digital traces and information we leave behind can quite easily be used to picture an individual, understand how a product is designed, see patterns, understand security procedures and arrangements and so on. In the wrong hands this can be really bad and this type of information is already very useful for burglars to know when people are away and industrial espionage for example. A small example of what could, technically, be in use today is recruiters knowing without asking that a female candidate is pregnant, don’t exercise or have a heart problem.
I am absolutely convinced neither consumers nor policymakers will let this development continue as today. And this is where I believe operators with a relevant brand can find their role in IoT beyond connectivity. A role which will be increasingly important and valuable as far out as I can see. Two good examples of operators I see moving in this direction today are Telefonica and Telia Company (see FAQ 6 and 7).
