5G services have the potential to revolutionize the mobile experience. Here’s how:
In a 5G environment, users will be able to experience life-like multimedia streams more freely. Users will feel as if they are part of the scene when they watch videos on their smart devices. An upcoming service that is expected to provide life-like experience in 5G system is UHD video streaming with its greatly enhanced resolution and clarity. UHD services over terrestrial broadcast are already being standardized in some countries. In addition, smartphones with cameras that can record video with 4K UHD quality are already available in the market. UHD services are expected to go mainstream by 2020, requiring enhanced performance in cellular systems to support such services.
Other examples of "immersive" services that would fundamentally revolutionize entertainment, health, education, and other industry sectors are Virtual Reality (VR) and Augmented Reality (AR). VR will provide a world where physical presence is simulated by computer graphics, and the user can actively interact with the simulated elements, as in immersive sports broadcasting for instance (See Figure 2). In an AR service scenario, computer-aided realtime information based on user context is graphically augmented to the display, delivering added value for the user, as in AR navigation on windshield for instance (See Figure 3).
Samsung is actively involved in the development of 5G technologies to support these immersive VR and AR services, which will entertain users and provide a truly life-like experience on the move.

Devices in future would be able to maintain network connectivity regardless of time and location, and be capable of communicating with other devices without human intervention.
The basic fabric of the 5G system design is the support for up to million simultaneous connections per square kilometer, enabling variety of machine-to-machine services including wireless metering, mobile payments and telemedicine. Intelligent devices will communicate with each other autonomously in the background and share information with each other. This ubiquitous connectivity - which is a basic tenet of the 5G services - will truly enable IoT services which in turn are expected to profoundly change human lives by connecting everything virtually.
In smart office environments, office appliances will be connected with one another and share information. Nearby computers and input/output devices would be able to recognize a user and adapt the settings autonomously based on the user’s preferences stored in the IoT cloud.
When a user steps into a shop, a smart device can alarm the information of new products that may match user's taste. Then, when the user approaches the product, customized alerts for discounted products can be sent to the device.
In a smart home, a smart refrigerator, recommending a recipe based on the ingredients that are in user's refrigerator, is a possible scenario. In addition, healthcare devices connected at home would be able to send vital signs such as heartbeat to an expert system in the hospital in real-time.
Users will be able to control remote machines and appliances as if they are right in front of them, even from thousands of miles away. Thanks to the reliable connections and near-zero latency of 5G, users will be able to control heavy industrial machines, or access hazardous sites remotely.
For safer driving, sensor and camera data in a vehicle as well as supplementary information from the neighboring vehicles will be collected using mobile networks so that a potential emergency situation can be reliably informed to a driver in real-time and timely procedures can be taken to avoid an accident. This operation can eventually be applied to self-driving cars .
