Most cellular network operators around the world still have a circuit switched core network today for voice and SMS services for their 2G/3G access networks. There are a few exceptions like one operator in India that launched with an LTE-only VoLTE network a few years ago. But apart from a few, that is the status … Continue reading Verizon: The End Of Circuit Switching – The End Of An Era
It’s been a while since I talked about LTE based technologies for the Internet of Things (IoT) or Machine to Machine (M2M) communication. Slowly but steadily, we are now seeing NB-IoT and CAT-M1 technology deployed in practice even though I would have thought things would move faster. 3GPP has not slept in the meantime, however, … Continue reading CAT-M Evolution in 3GPP Rel. 14
We are quite a bit into January 2018 already and I still haven’t come around to reflect which things from back in 2017 ‘moved’ me. But finally here we go this is my 2017 round up from cellular to history.
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
After reading about the MKRFOX 1200 Arduino with built in Sigfox connectivity and a 2 year subscription for 50 Euros (including VAT and shipping), I ordered one right away and was pleasantly surprised that it arrived only a few days later. This and the following posts document my first impressions and give a basic overview … Continue reading The Sigfox Arduino – Part 1 – First Impressions
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
