5G security is built firmly on the foundations supplied by 4G security, albeit with significant enhancements. Here we’ll look at what’s stayed the same and where the differences are in how security is implemented in 4G and 5G. A deeper dive into this topic is available in our 5G Security course. 5G - an evolution not a complete change 5G can be viewed as an evolution of 4G rather than as completely new technology with many 5G features being enhancements, improvements or extensions of the equivalent 4G features. This principle can be seen quite clearly in the area of 5G network security...

5G Network Slicing seems to be one of the hottest buzzwords around at the moment. If you’re looking for an introduction keep reading or have a look at our new course in this area. 5G as a platform delivers in two major areas. Firstly it brings cost efficiency through access to huge areas of new spectrum and the effective use of advanced antenna techniques. It also delivers significantly improved performance and capabilities centred largely on reduced latency, increased reliability, and lower energy use. Although requiring significant initial investment, the first area will allow progressive and cost-effective deployment of much needed capacity into the...

5G, Network Virtualization -

The 5G core network architecture is designed to be cloud native making use of NFV (Network Function Virtualisation) and SDN (Software Defined Networking). NFV is used to decouple the logical function of a network element from its associated hardware and implement that function in software as a VNF (Virtualised Network Function). The VNF may be run on general purpose, off the shelf computing platforms. The VNF may be run on general purpose, off the shelf computing platforms. The main feature of SDN is a clear separation between control and user plane functions. SDN supports centralisation of control plane functionality while at the same time supporting...

5G -

LTE was designed mainly for the delivery of mobile broadband over smartphones. However, a progressive flattening of broadband revenues has led network operators to seek out new markets and new use cases, in which connectivity can provide economic benefits. These use cases often have different use cases from those of mobile broadband. Some of them, for example mMTC (Massive Machine Type Communications), can be addressed by enhancing the LTE specifications. However, other use cases cannot be supported so easily over LTE, and require a new technology to address them properly. The technology is known as the 5G New Radio (NR)....
