# Revolution or Evolution? Technical Requirements and Considerations towards 6G Mobile Communications
## 3 Use Cases and Applications of 6G  
This section presents some of the potential use cases and applications of 6G for industry and public consumers. Fifth generation is evolving, and what has been deployed in 5G mainly focused on mobile broadband, while other aspects of 5G, such as automation, low latency, and high reliability for manufacturing, e-health, gaming, and connected vehicles, are yet to come and are subject to the Release 16, 17, and 18 [33; 34; 35]. The network technology is evolving to a flexible and agile infrastructure, and it is expected that 6G, like the previous generations, will be influenced by today's emerging technologies. \"Twelve Global Megatrends\" key themes are expected to shape society at large by 2030, as proposed by Frost & Sullivan's Visionary Innovation Group [36]. The 6G network will satisfy the requirements of many forthcoming technological trends and themes, such as factories of the future, autonomous mobility, and towards \"zero\" world (\"zero\" energy, touch, and error). So far, communication systems have transmitted data that interact with the two human senses, hearing and seeing. Thus, one of the main goals of 6G is to transmit data related to other human senses, such as touch, smell, and taste. This additional human sense transmission refers to the fourth dimension (4D), which will allow the communication systems to transmit other sensory information, such as air, noise, and light pollution. In this regard, 6G can be broadly characterized as integration between communication and sensing, which would lead to much smarter, relevant, and personalized services and would effectively and naturally integrate the physical and virtual world together [37]. Sixth generation is also going to use mobile technology to deliver AI to everyone, anywhere, at any time, that will leverage the 6G wireless network as a sensor network. Therefore, by integrating communication with sensing and AI, 6G will be an intelligent network that will open and unlock several new industrial applications, such as intelligent video analysis, real-time ubiquitous intelligence systems, and intelligent customer engagement services. The following points list some of the potential applications of 6G [38; 39]:  
* Transportation: autonomous vehicles interacting with the environment and cooperating driving. * Retail: near real-time and end-to-end no-touch transactions from production to consumption. * Manufacturing: autonomous and dynamic reconfigurable production lines based upon near real-time demand. * Healthcare: robotic controlled surgery, remote surgical procedures, and enhanced precision surgical capabilities. * Industrial/Public: cooperative manufacturing, massive embedded intelligence, low-power sensor deployment across supply chain and surroundings. * High fidelity gaming: Play instantly without download, subscription enabled, and direct distribution model. * Robotic construction: autonomous worksite equipment, real-time on-site planning and construction. * Instantaneous delivery: massive fleet logistics and dynamic delivery locations. * Automation: process automation, cognitive process automation, virtual agents and analytics, AI- and machine learning (ML)-based execution, and intelligent enterprise. * Truly immersive extended reality (XR): Combining VR, AR, and mixed reality (MR) and utilizing it in entertainment, medicine, science, and education. * High-fidelity mobile hologram: as a next-generation of media technology to provide real-time services. In 6G, ultra-reliable low latency communications (uRLLC), enhanced mobile broadband (eMBB), and massive machine-type communication (mMTC) will be extended to another three dimensions [40], which are ubiquitous mobile ultra-broadband (uMUB), ultra-high data density (uHDD), and ultra-high-speed-with-low-latency communications (uHSLLC). Meanwhile, uMUB in 6G systems enables the transmission of any desired performance throughout the space-aerial-terrestrial-sea domain.
