This is an activity to innovate the national industry by digitizing the entire process of the existing manufacturing industry using information and communication technology and transforming it into a future high-tech industry (Digital Transformation). Production of products, production systems, and related businesses, as well as manufacturing linked thereto. Includes activities.

Smart factory manufacturing refers to an intelligent factory that improves a company's productivity and quality by implementing automated and digitalized factories by applying ICT technologies such as IoT, AI, and big data to all or part of the manufacturing process.

The main terminals connected to the network at existing industrial sites were PCs and smartphones, but recently, different communication connection requirements have been introduced for robots, drones, sensors, 4K/8K CCTV, AR/VR devices, and autonomous vehicles (AGVs). Various devices with are connected to the 5G commercial network, and based on the three characteristics of 5G, eMBB, URLLC, and mMTC, many devices are capable of real-time monitoring and control due to ultra-low latency characteristics, and Big Data processing and AI due to large-capacity information transmission characteristics. The need and usability of smart manufacturing and factories incorporating technology are being demanded.

The 5G commercial network is built around NSA (None Stand Alone) Mode and provides services that coexist with LTE. In Korea, the N78 Band 3300~3800MHz frequency and the N257 Band 26.5~28.9GHz are used as commercial 5G networks.

Specialized networks refer to private 5G networks in which specific companies and organizations build their own networks. In the case of Korea, the N79 Band 4.72~4.82GHz and N261 Band 28.9~29.5GHz frequencies are used, and the specialized network is a communication method that provides specialized services for specific buildings and specific field services, especially IIoT IIoT: Industrial Internet of Things, a wide range of industrial objects.
