1 INTRODUCTION
5G is said to be disruptive…. change is evident and it is unknown what the future may hold. And yet,
analysts are projecting the expected results from 5G technology while the early stages of trials and pre-
standardized deployments are just beginning and commercial 5G deployment is clearly on the horizon.
5 Billion people forecast to be accessing the internet via mobile by 2025
5G coverage will roll out rapidly to cover 440 percent of the global population by 2025
5G will account for almost 1 in 7 connections (14 percent) by 2025
Global penetration rate for all mobile connections will reach 110 percent worldwide by 2025
9 Billion mobile connections by 2025
5.9 Billion unique subscribers in 2025
25 Billion Internet of Things devices globally in 2025
(11.4 Billion Consumer IoT; 13.7 Billion Industrial IoT in 2025)
Global Mobile Annual Revenue of $1.1 Trillion in 2025

All of this may be enabled through the LTE-Advanced and 5G specifications created by hundreds of
contributing scientists and engineers at the Third Generation Partnership Project (3GPP). The
transformation to 5G will also transform our lives, our economy, our jobs, our industries. The early signs
are beginning to show. Wearables are developing in such a way that they may become self-contained
mobile computing devices, for example the cellular Apple Watch or connected glasses. The big expectation
is the connected car; autonomous vehicles will give us back commute time for new activities in our lives.
The healthcare system is changing as remote monitoring and robotic surgery provides a different level of
care. Drones will be used for transportation, surveillance and rescue operations. Robots and Artificial
Intelligence (AI) will result in a new relationship for both humans and machines. The wireless industry is
virtualizing; Multi-Access Edge Computing (MEC) is going to redefine computing itself and certainly impact
the mega-networks of things in the future… billions of connected things… billions of connected people…
and a major shift in network operations and management.
Since the wireless industry coalesced around Long-Term Evolution (LTE) in recent years, it has brought
together the entire mobile industry, evolving deployments to a single technology, enabling an ecosystem
larger than ever before. Already more than a quarter of all global mobile subscribers are using (LTE) and
it’s expected that by 2021 this will increase to more than half. While LTE deployments continue to expand,
and grow across the world, certain regions such as Korea, Japan, China and the U.S. have nearly reached
or exceeded 90 percent penetration of LTE. This pushed up the focus in the mobile industry towards 5
th
Generation (5G) mobile technology, standards development, demos and trials. There continues to be
growing demands for higher throughputs and more data capacity, particularly for video, to provide better
broadband services. But data demand is just one of the drivers for 5G. In addition, 5G is targeted to address
new vertical markets including massive Machine-Type Communications (mMTC), Ultra-Reliable Low
Latency Communication (URLLC) and a broad range of Internet of Things (IoT) applications in general.
The evolution of LTE (LTE-Advanced Pro) continued its standardization in 3GPP Rel-14, which was frozen
by mid-2017 and potentially ended specifications on LTE -- a decade since its initial specification in Rel-8 -
- included features such as further Multiple-Input Multiple-Output (MIMO) antenna enhancements, Carrier
Aggregation (CA) enhancements, enhanced Licensed Assisted Access (eLAA), enhanced LTE Wireless
Local Area Network Aggregation LWA (eLWA), Voice-over-LTE (VoLTE) enhancements and
