Time flies and it’s already 3 years since the previous edition of my book became available. Time for an update and I’ve worked hard over the course of the past 12 months to ensure my introduction book on wireless networks continues to reflect the latest state of how the technology is deployed and functions in … Continue reading From GSM to LTE-Advanced Pro and 5G – My Latest Book Is Now Available!
One of the new features of 5G networks is ‘Network Slicing’. So far I couldn’t really get my head around the concept, everything I heard was just too abstract to make practical sense. Finally, however, things are getting more concrete and 3GPP TS 38.300 has an interesting section of how network slicing will work on … Continue reading 5G – Part 2 – Some Thoughts On Network Slicing
After test driving the Mkrfox 1200 Arduino with Sigfox functionality on board and giving an introduction to programming in the previous two parts it’s time now to have a closer look at some of the basic parameters of a Sigfox network to get an idea of the capabilities and constraints, what that means for devices … Continue reading The Sigfox Arduino – Part 3 – Sigfox Network Basics
This is part 2 of my telescope view on how OneM2M works and deals with a number of additional topics. If you haven’t read part 1 I strongly recommend you do this first before continuing here.
The Internet of Things and Machine to Machine (M2M) communication are not only buzz words in the computing industry today but also in the telecoms sector. In telecoms there is a framework referred to as OneM2M that I’ve come across several times before. However 99% of what I found on the Internet did not bring … Continue reading A Telescope View on How OneM2M Works – Part 1
When the Raspberry Pi came out it was a game changer as for the first time a cheap and easy to use Linux based board with lots of connectivity became available to the masses. Last week I read about a new Arduino board with a Sigfox chip that could be another game changer.
Like every year, time has flown and it is already end of December and thus time to look back at what has happened this year that has literally ‘moved’ me. This year I have three categories: Networks, Linux & General computing and Miscellaneous Other Things. Let’s start with a look back at my year in … Continue reading Things That Moved Me In 2016 – Part 1: Networks
In an earlier post I had a a look at the different options for Cellular IoT (NB-IoT) when it comes to connectivity. One of the options is to use the cellular control plane to forward the raw data without wrapping it into IP data packets (NIDD, Non-IP data delivery). At the time I wondered a … Continue reading Does an IoT device need an IP address?
Another NB-IoT number floating around is that very power efficient NB-IoT devices should be capable to be driven from a small battery for more than 10 years without needing a recharge. Again, I wondered where this number comes from and which assumptions were made to declare that this is possible.
There is an interesting number floating around in various whitepapers and articles on IoT: NB-IoT supports 50.000 devices per sector per cell. So where does that number come from and is it realistic?
