What is 5G?

5G refers to the 5th Generation Wireless System. The 3GPP (3rd Generation Partnership Project), a global telecommunications standardization body, is the main setter of 5G specifications. Since 2015, it has launched 5G standardization pre-research to understand the new services and technical requirements required by the market. In 2018 and 2019 it released its first and second stage 5G technical standards respectively.

Three goals set by the International Telecommunication Union (ITU) for the formulation and use of various 5G standard technologies are to achieve: enhanced mobile broadband (eMBB), high reliability and low latency communication (uRLLC), and large-scale Machine type communication (mMTC). In short, the three major characteristics of 5G are: "high speed", "low latency" and "multiple connections".

From 1G, pure analog voice communication, to 2G for sending text messages, to 3G for basic Internet access, to 4G, where many people use mobile phones to watch movies and play games, developments in mobile phone technology have surpassed those of the computer. This was absolutely unexpected when mobile communication first started. Every generation of communication technology has responded to the evolution of market demand. When new services are launched, consumers' usage habits also change. 91ÊÓƵ¹ÙÍøever, compared with 3G and 4G, which developed in response to consumers' needs for mobile services, 5G has developed more as a way to meet the needs of industrial development, having a wider range of applications than previous generations of communication technologies.

In addition to its high speed, two other features of 5G are its multi-connection and low latency capabilities. These features help enterprises accelerate digital transformation and solve many of the pain points in the development of factory automation technology.

Taking automated guided vehicles (AGVs) commonly used in automated production lines as an example, AGVs are mainly used to perform logistics handling between production lines, which can improve productivity and reduce labor costs. 91ÊÓƵ¹ÙÍøever, AGVs are mostly driven by Wi-Fi connection. The frequency band used by Wi-Fi is a license-free open frequency band. Not only is the connection quality susceptible to interference from other devices, but also information security risks. In addition, when Wi-Fi switches between different base stations, it needs to be reconnected. This may cause the unmanned vehicle to be disconnected or stopped during the moving process, which can affect the operation efficiency of the production line. Through the low-latency and multi-connection features of 5G, the unmanned vehicle has a more immediate signal response time. Multiple devices can be connected at the same time through a command and dispatch platform, allowing for multiple tasks to be performed with improved stability.

In addition to unmanned vehicles, another key technology in industrial automation is automatic monitoring. Automatic monitoring is the monitoring of production line status through artificial intelligence image recognition technology. For automatic monitoring to be carried out smoothly, the high transmission speed of 5G is required to transmit high-resolution images to the back end of the computer in real time. In the event of industrial safety hazards, with low-latency support, the system can quickly react. In the Internet of Things (IoT) era where all devices are connected and driven by the network, 5G will penetrate into various vertical industries, such as smart retail, smart medical care, and smart transportation, and enhance the development of infrastructure in various fields.
