5G – the book


Our book “5G Mobile and Wireless Communications Technology” has just been published by Cambridge. This is where you will find a full overview of the 5th generation of mobile communications (5G), including use-cases, spectrum aspects and technologies. Let me share with you the story of this book, which mirrors the journey of 5G to date.

If you are a mobile network operator, a regulator, an industry ICT/IoT technology strategist, or an ICT/IoT researcher, this book will hopefully equip you with an insight into the impact and opportunities of 5G.

Model Driven Networking: Looom


Routers used to be embedded systems. They are now complex, distributed systems. So a new design approach is needed to control complexity. We have developed Looom for this – a model driven networking approach.

In this post we’ll take you through a review of the network control plane of today, the history that explains some of the legacy we have in network systems, and dive into our concept, which opens up the ability to define new protocols and services to a much wider group of engineeers and scientists.

Narrowband IoT standardization soon finalized


A new NB-IoT (Narrowband Internet of Things) standard will get us a radio technology that supports massive deployment of IoT devices. It will meet tough requirements on low device complexity and very low battery consumption, as well as extend the coverage range substantially compared to other 3GPP technologies.

Last week, about 40 participants from several companies attended the 3GPP RAN4 meeting in Kista, Sweden with the objective to advance the NB-IoT standard.

IoT Networking

Tokyo in Autumn_3

IoT networks may be built in different ways. Devices can be directly connected to the 5G system, or they can connect through capillary networks using short-range radio to extend the 5G network reach. For efficient management, different radios need to be served in the same IoT platform. At the MWC we showed how to easily manage different capillary topologies and discuss capillary radios such as Bluetooth Low Energy. Continue reading
