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
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
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?
At the end of the 1990s I was working on embedded devices that monitored the wear of wind turbine gears and which could be accessed remotely via a dial-up circuit switched modem connection. This eventually evolved into using the dial-up modem of the device to let it connect to the Internet so it could be … Continue reading The IoT Elevator Pitch
The Internet of Things (IoT) that some are also calling the “Internet of Targets” is currently one of the hot topics in wireless. One flavor of IoT is Cellular-IoT for devices that for some reason can’t be connected to a local area network and only infrequently transmit small amounts of data.
In the previous post I had a couple of links to interesting information on what is between an antenna and the baseband radio chip in today's smartphones. As a quick follow-up here's my cheat-sheet which lists the components which is best used with this diagram over at Anandtech: Downlink (Receive, RX) Path: RF Front End … Continue reading More Details on What’s In Front of the Baseband – Part 2
