Cellular IoT – How to find out more about NB-IoT in 3GPP – Part 5

In part 4 of my mini-series about 3GPPs Internet of Things standardisation for cellular networks I’ve given an overview of the currents state of the NB-IoT standardization in 3GPP. Most of what I’ve written in there is based on a 3GPP Technical Report that summarizes the different options that were studied and RP-151621 which contains … Continue reading Cellular IoT – How to find out more about NB-IoT in 3GPP – Part 5

I haven’t written a lot about the Internet of Things (IoT) so far as there are so many different approaches discussed, specified, prototypes tested and proprietary solutions rolled out these days. In other words, it’s not easy to keep an overview and to get a feeling which solutions might might become popular and which will … Continue reading Cellular IoT – The Dust Slowly Settles – MTC, NB-IOT and Things In Between – Part 1

My 6G-Kickoff

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

Verizon: The End Of Circuit Switching – The End Of An Era

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
