Over the past months, 3GPP was quite busy to ensure the NB-IoT made it into Release 13 before time ran out. So far, I’ve been looking into CRs and the Work Item description to get an idea of what is standardized because the Release 13 specification documents themselves did not yet contain NB-IoT content. Fortunately … Continue reading Cellular IoT – Part 8 – A Whitepaper and 3GPP Spec References
This is part 7 of my series on Cellular-Internet of Things (CIoT) and NB-IoT. So far I always thought things above layer 2 were simple. There’s IP and that’s it then. But recently I came across an interesting paper by Rhode & Schwarz that suggests that this might not necessarily be the case.
In the three previous parts (here, here and here) on the Internet of Things and 3GPP, I’ve described Cat-1, Cat-0 and Cat-M1 devices. In this post we get down to the really interesting development in 3GPP on this topic: Narrow Band Internet of Things (NB-IoT) and Cat-NB1 devices (previously referred to as Cat M2 devices).
After an overview in part 1 and and introduction to rather simple enhancements for the Internet of Things (IoT) with LTE Cat-1 and Cat-0 devices in part 2, this 3rd part in my mini-series on the cellular Internet of Things (IoT) takes a look at some of the more profound changes in the LTE specifications … Continue reading Cellular IoT – The Dust Slowly Settles – Part 3 – Cat-M1 Devices
In part 1 on this topic I’ve been giving a quick overview of Machine Type Communication (MTC) and Internet of Things (IoT) from a cellular network operator and 3GPP point of view. In this post I’ll jump right to the first couple of enhancements made the 3GPP LTE specifications over the years to show which … Continue reading Cellular IoT – The Dust Slowly Settles – Part 2 – Cat-1 and Cat-0 Devices
