2018 was a very interesting year for us and technology. We introduced our IoT product “Souly”. 5G entered the normative work in standardization and released the first “version” of 5G. Wi-Fi introduced new security schemes and changed nomenclature. The networking world shifted towards SDN/SD-WAN solutions.

LTE and 5G Differences: System Complexity

In this post we discuss the complexity that 5G brings and show some examples of this as compared to LTE including: naming in the 5GS architecture, dual connectivity options in 5G, parameters for L1, base station naming, spectrum aspects.

LTE and 5G Differences: Function Decomposition Between RAN and CN

Let’s take a quick look at some of the differences between LTE and 5G in the area of functional splits between RAN and Core Network. We show and discuss high level splits of selected functionalities of the main “network functions/nodes” in both systems (discussing it from the 3GPP RAN3 WG perspective) from which we can make some conclusions on the differences between those two systems.

5G Core Network Functions

This post touches upon the 5G network functions (NFs) related to core network. Some of them look very similar to the corresponding functions in the previous generations’ core networks. This of course is not surprising, as the network always has to carry out some basic functions such as: communicate with the UE, store its subscription and credentials, allow access to external networks & services, provide security and manage the network access and mobility. However, we will also see some new functions, not present before, which are needed to enable the new network paradigms like slicing and service-based networking.
