It’s the time of the year again to reflect on what has happened in the last 12 months. It’s been quite a ride again, with many things happening, and also some things not happening. So if you are interested, come with me on a trip through my year in tech 2023.
After exploring many new technical topics over the past few months, including Docker and Kubernetes, I ventured out over the weekend to have a look at OpenStack. I wanted to have a closer look because OpenStack is used to provide a private cloud infrastructure, i.e. virtual machines (compute), storage, and networking for many projects. OpenStack … Continue reading Playing with OpenStack – A Rather Unpleasant Experience
Since 2018, I’ve been working in the area of putting 5G into practice. Back then, early versions of the 3GPP Release 15 specification had become available and equipment vendors started shipping first hardware and software. The standards were not developed overnight, however, but were preceded by visions, ideas, studies, and trials by at least half … Continue reading My 6G-Kickoff
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
Happy New Year 2020 to all of you! It’s the time of the year again when it makes sense to take a look back at the last 12 months of 2019 to see which tech things and events ‘have moved me’ during the course of the year. Like in the previous years, it is once … Continue reading Things That Moved Me in 2019
In the previous two parts on the topic I’ve been looking at why there is a need to evolve the initial 5G network architecture in which 5G base stations are merely a side-kick to the LTE access and LTE core to a pure 5G access and a 5G core network. There are several ways how … Continue reading 5G Beyond Option 3 – Pt. 3
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
Back on the history track again, I picked up an electronic copy of Leslie Berlin’s ‘Troublemakers – Silicon Valley’s Coming of Age’ about the early days of Silicon Valley. I’ve read quite a number of books about the rise of Silicon valley in the past, some on famous people like Steve Jobs but most on … Continue reading Book Review – Troublemakers
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.
A few days ago on a sunny but freezing cold Friday afternoon I had a few hours to visit the Centre for Computing History in Cambridge. I was very much looking forward to it as the first computer I ever programmed on was a Sinclair ZX80 that was built in the UK back in 1980 … Continue reading The Computer Must Be Earthed!
