5G for Hyper-connected Society
|In the era of the Fourth Industrial Revolution, everything is connected and analyzed. It is also believed that the cyber space may not be discerned from the real world eventually. However, explosive data growth expected by the Fourth Industrial Revolution cannot be handled by existing network infrastructures. This is where the 5G mobile communication network plays and why 5G is called a “steam engine of this age.”
5G technology is characterized as ultra-fast speed, ultra-low latency, and hyper-connectivity. A physician on the land can operate on a patient at a medical facility in an island village through a hologram delivered on 5G networks. And 5G technology realizes offline services in the virtual world such as finance, shopping, and performance that has been provided in the real world. In addition, ultra-high-quality media such as UHD and VR / AR are delivered to users through 5G networks as if they are actually seen.
It is also expected to evolve into a hyper-connected society developed through 5G and IoT technologies. For constructing the hyper-connected society, the smart city and the smart factory are essential components. The 5G infrastructure built in the smart city delivers traffic signal and intersection conditions to autonomous vehicles, letting them know which lane they should move to. Additionally, IoT devices detect accidents and disasters in the city and simultaneously spread the disaster situation through the 5G network, greatly reducing the risk. And the smart factory can replace human labor with machine operation through unmanned process in factory for citizen to concentrate on creative work.
In a world where everything is connected, information security threats must be carefully addressed. Attacks on traffic, electricity, and communication infrastructure control systems in the smart city will pose a serious threat to social safety. And if manufacturing information and systems in the smart factory are attacked, corporate losses will be astronomical. Therefore, strong communication security by 5G infrastructure will be a basis of the bright future of the hyper-connected society.
