Overview of telecom network architecture

“

Did you know that the hardware-powering legacy networks might be holding back the innovation? That is what has happened in the telecom space. Today, we will uncover how traditional telecom infrastructure became trapped in proprietary systems and why this matters deeply for our future networks. Let's break down the network. At a higher level, we know there are three components, which is radio access network, transport network, and the core network. But under the hood lies a major bottleneck in legacy networks. Every component in these networks is built as closed, vendor-specific hardware. That means there is no mix and match of different vendors for different equipments. There is no choice and less scope of innovation. If we start with the legacy networks, for example, 4G, where we have the architecture starting from the radio access network, let's understand how it worked so far so that we can compare it with the 5G networks and its architecture and evolution. So in case of 4G…
