The Route To 5G

The key features of next generation cellular communications and the key technology components required.


The mobile phone has seen explosive growth over the last two decades to become an essential part of our everyday lives. Right from the outset, ARM has been at the heart of these devices enabling ever more sophisticated capabilities whilst maintaining a focus on maximizing battery life through industry leading power efficiency. The complexity of smartphones is not often fully appreciated, with the average smartphone containing over 10 ARM based processors managing functions such as touch screen, sensor processing, location/positioning, camera, graphics, applications as well as the ever growing plethora of connectivity such as Wi-Fi, Bluetooth and LTE.

With the wireless industry gearing-up to standardize the next generation of mobile broadband devices, or so called ‘LTE-Advanced Pro’ and ‘5G’, this white paper takes a look at what that will mean in terms of technologies, challenges and the use cases that it will ultimately enable. In particular we look at how the recently announced ARM Cortex-R8 real time processor ‘under the hood’ will enable a new breed of multi-Gigabit devices whilst still keeping power efficiency at the heart of its design
