    5G Core Network – a Short Overview

    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 […]

    LTE-Advanced Pro with WiFi: RAN-level integration

    WiFi has been considered as an offload mechanism since the introduction of LTE in 3GPP Rel-8. However, the initial inter-working between the two Radio Access Technologies (RATs) was very loose, with WiFi connected to the Evolved Packet Core (EPC) with the help of add-on functions (such as ANDSF hidden deep in the network) making suggestions for […]

    5G Energy efficiency – how to achieve it?

    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 […]

    LTE-Advanced Pro – what is evolved LTE?

      As 3GPP Rel-13 has been already frozen (with the exception of Narrow Band IoT), the time has come to provide an overview for the evolved LTE under the name of LTE-Advanced Pro. As already mentioned in one of the previous articles (LTE evolution: from LTE, via LTE-Advanced, towards LTE-Advanced Pro), LTE-Advanced Pro is a […]

    Will a mobile system (finally) become an alternative to fixed access?

    With the recent hype on 5G, an interesting question could be raised, namely: will a mobile system finally become an alternative to fixed access? Can we really answer that question at this point? As of now, we cannot say for sure what 5G will become, since its still being discussed, the requirements specification is ongoing, and the actual […]

    HetNet challenges with an outlook towards 5G

    Booming mobile data demand observed in cellular networks all over the world and forecasted by various studies (e.g. Cisco VNI[1]), driven by the increasingly growing availability of wide range of data-hungry mobile devices, is commonly considered as the main driver for mobile networks evolution Towards 5G. It’s not only the smartphones, tablets and/or phablets with […]

    Radio networks technology trends – a look back to 2011

    To start our journey towards the deep waters of radio networks and future mobile communications, I would like to move us back a couple of years, where we just entered the world of 4G with the introduction of LTE-Advanced. So if we imagine to be in 2011, the telecom trends back then looked like this… We are in […]
