In an interesting post over at RCR Wireless, I noticed today that AT&T is about to shut-down their LTE NB-IoT network. And not only in a couple of years from now. No, the full shutdown is scheduled for Q1/2025. So surely there will be a new and shiny replacement technology in place? Hm, no, not … Continue reading AT&T Quits LTE NB-IoT
In the previous post on the topic, I’ve been looking at how 3GPP has studied and then extended the LTE and 5G NR air interface so it can be used over a satellite link. For transmitting data to and from smartphones with omnidirectional antennas over satellites, 3GPP has extended the LTE Narrowband Internet of Things … Continue reading NTN Part 2 – NB-IoT over Satellite
In the previous post I had a lot at how I can get my newly acquired NB-IoT module connect to the network. This is part two that now focuses on how to actually send some data back and forth across the NB-IoT network to a server on the Internet.
Back in 2016 and 2017 I had quite a number of articles on NB-IoT, the Narrow Band Internet of Things technology that can run alongside LTE to connect things to the Internet over the cellular network. From being very power efficient to run over years on batteries to increased in-house coverage, the standard contains a … Continue reading NB-IoT From Theory To Practice
Back in April I wrote a post about a breakthrough Arduino board with a Sigfox chip bundled with a 2 year network subscription. It has since arrived and a number of posts about how it performs in practice will come soon. In the initial post I wrote that in my opinion that’s where 3GPP network … Continue reading An NB-IoT Shield That Includes A 1 Year T-Mobile NL Subscription
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
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.
In the previous episodes, I’ve gone into some of the details of the Non-Terrestrial Network (NTN) extensions specified in 3GPP Rel. 17 36.300 and 38.300. One main aspect I haven’t addressed so far is mobility, so let’s have a look at that today! Actually, mobility in NTN is even more fun than in terrestrial networks … Continue reading NTN – Part 6 – Satellite Mobility
In part 1 of this series, I’ve taken a high level look at how the LTE and 5G air interface specifications have been extended in 3GPP Release 17 to accommodate for weaker signals, longer delays and patchy coverage typically experienced over satellite. In part 2, I’ve chased the question why the LTE NB-IoT and CAT-M … Continue reading NTN – Part 3 – 3GPP Rel. 17 – System Architecture for Satellite Services
