2017 was a very exciting year with a lot of new technological trends emerging such as 5G, IoT, MTC, SDN, etc. We tried to cover a vast variety of topics in our blog posts and also introduced the Grandmetric Guidepaper to get deeper understanding of the technological concepts.

In this blogpost, we will discuss the most popular LPWAN technologies which are present in the current market that enable “Connectivity” for these IoT devices.

The 5G System (5GS) will have three main components as defined below: 5G Access Network (5G-AN) 5G Core Network (5GC) Use Equipment (UE) This blog is dedicated to describing the main components of the 5G Core Network as defined by the ongoing efforts at 3GPP SA [1]. The 5G system is being designed to support […]

One of the key requirements for new generation networks like 5G is energy efficiency, meaning reduction of network energy consumption. Example techniques to assure high energy efficiency in mobile networks include: the use of lean carrier, dynamic beamforming, efficient energy saving schemes for Small Cells, virtualization of the network and utilization of dense deployments.   Energy […]

As the “5G” research and standardization is progressing, I would like to elaborate a bit on some concepts that are potentially serving as building blocks for the future systems. They are divided in this post into: Air interface and Networking concepts.   Selected air interface aspects millimeter Wave (mmW) – The high-frequency ranges are currently becoming […]
