5G Training, 5G System Survey Training

An important part to understanding 5G protocol and architecture is having a firm grasp of the big picture 5G core network.

The 5G system has been designed to support data connectivity and services which would enable deployment, by the industry, using new techniques such as Network Function Virtualization and Software Defined Networking.

The need for these new techniques was due to the various different profiles of data services that need to be supported by the 5G network. Previously, mobile networks had been designed keeping the average smartphone user in the center but with 5G this has changed as with the boom of data connectivity various use cases having completely different data requirements have come up and the network operator needs to satisfy all these requirements as efficiently as possible.

With this in mind, the 3GPP (standard organizations) has kept the basic idea of having a flat architecture where the Control Plane (CP) functions are separated from the User Plane (UP) in order to make them scaling independent allowing operators to use this functional split for dimensioning, deploying and adapting the network to their needs easily.

For 5G to be deployed, a whole new air interface had to be developed.

An air interface is the radio frequency portion of the circuit between the mobile device and the active base station. The active base station can change as the user is on the move, with each changeover known as a handoff.

5G was initially made available in April 2019, through improvements in LTE, LTE-Advanced and LTE Pro technologies. But this has all led to standalone (SA) 5G, a major step-up with the introduction of a new air interface.

Understanding 5G protocols and architecture takes a bit of doing – especially if you’re not a systems engineer.

Perhaps one of the best ways to understand 5G is by taking a look at the truth behind the architecture – both the good and the bad.

People refer to 5G as revolutionary. 5G is revolutionary because it replaces the hardware components of the network with software that “virtualizes” the network by using the common language of Internet Protocol (IP).

5G is often called “evolutionary.” 5G is evolutionary as both its new radios and the core network functions are defined as a progression from 4G. Like 4G before it, in most markets 5G has rolled out in steps with the goal of standalone (SA) status (independent of 4G technology). 5G is also spectrum dependent. In the long run this means new spectrum allocations. While carriers build out their 5G only infrastructures, the 5G era has begun using old spectrum assignments.

When people call 5G transformational, that’s not exactly true. 5G is not transformational, per se. What will be transformative are the applications that will use the network. The United States was not the first to deploy any of the “G’s” of wireless networks, but nonetheless dominates the wireless ecosystem because of the innovative technologies developed by American entrepreneurs for those networks.

If you’ve heard that 5G is a cybersecurity risk – that is extremely true. 5G is a cybersecurity risk because the network is software based. Earlier networks’ reliance on centralized hardware-based functions offered a security-enhancing choke point. Distributed software-based systems, per se, are more vulnerable.
