5G for mobile augmented reality

Recent years, remarkable progress was made with 5G and mobile consumer devices. The 5G network as a technology inherently brings aspects such as high-speed, ultralow latency, and high bandwidth—all in a wireless communication network. 5G will especially help establish the Internet of Things as an indispensable part of our world, by laying the foundation for unleashing its full potential. It is a long way to when 5G becomes mainstream, but businesses need to start now with developing and reimagining services and products to leverage 5G's superior capabilities. Moreover, modern mobile devices, such as smartphones and tablet computers, offer multicore processors and graphics processing cores which open up new application possibilities such as augmented reality (AR) and virtual reality (VR). AR is a key technology that will facilitate a major paradigm shift in the way users interact with data and has only just recently been recognized as a viable solution for solving many critical needs. Enter AR technology, which can be used to visualize data from hundreds of sensors simultaneously, overlaying relevant and actionable information over your environment through a headset. 5G makes AR technology much faster, with much more data flow. With easier and more accessible use, for a variety of different functions (besides video gaming), widespread adoption seems likely. In summary, AR in the era of 5G is a really cool upcoming wave where the vast repositories of data will enable an AR lens into the scenarios in ways that provide near immediate insight at a level of depth unimaginable previously. This special issue brings the latest results over 5G and mobile AR technologies for various applications. It can help technicians to exchange the latest technical progresses. “Privacy Information Antistealing Control Method of Medical System Based on Cloud Computing”1 explored the privacy information antistealing control method of medical system based on cloud computing.
