1. Introduction

1.1 The Evolution of Telecom Networks

Telecommunications have evolved significantly, from manual operations in 2G and 3G to semi-automated systems in 4G and 5G. With the advent of 6G, networks are poised to achieve ultra-high speed, reliability, and energy efficiency, marking the transition to fully autonomous operations.

• 1G introduced basic voice communication
• 2G added digital voice and text messaging
• 3G brought mobile data
• 4G introduced high-speed internet
• 5G enabled new applications that require ultra-low latency and allowed for the roll-out of the ‘Internet of Things’, or smart devices.

6G technology is anticipated to build on these advancements, promising a new era of wireless networks that cater to the increasing demand for high data rates and connectivity. The definition of 6G technology revolves around the idea of merging the physical, digital, and biological worlds, creating a hyper-connected – or ‘smart’ – society.
