'Smart City'is the usage of advanced information and communication technology (ICT) to solve traffic problems, environmental problems, housing problems, and facility inefficiencies caused in city life so that citizens can enjoy a convenient and pleasant life.
An urban area that uses various types of electronic data-gathering sensors developed by advanced information and communication technology (ICT) to acquire information and use it to efficiently manage assets and resources. The purpose of using information and communication technology is to solve traffic problems, environmental problems, housing problems, and facility inefficiencies caused in city life, and to enable citizens to enjoy a convenient and pleasant life.

Based on IoT smart devices, we develop IoT platforms and services that automatically control various home appliances
and electrical devices in homes and offices/stores, and provide crime prevention and security services
Hub type Wall outlet
Hub type light switch
Hub type smart plug and multi-tap
○ IoT communication terminal environment → Changes in IoT dedicated networks of telecommunication companies (current situation)
- SKT → Stop LoRa network service/ New establishment of Cat.M1 network, KT → NB-IOT service service/ LGU+ → NB-IOT service to be discontinued
○ Designated as a small business field, KT NB-IOT-based remote meter reading IOT communication terminal development started, SKT Cat.M1 selected as a power meter reading operator
- LoRa communication module development boomed from 2016, but failed due to packet size limitations and Up/Down link problems
Recently, a lighting control system is being built using LED lights to save energy in underground parking lots
In the past, wired communication was used due to technical limitations, but recently, a control system using wireless communication has been established
However, although the wireless communication network for the wireless control for lighting control is built in the parking lot, the parking guidance and emergency bell system are being built in the form of wired communication through a separate operator
Parking guidance lamps, LED lighting control, and emergency bell control systems have been developed and configured, resulting in complicated wiring and increased installation costs
○ Object recognition traffic volume measurement technology
> Applied to the city of Pittsburgh by Sutrac, USA
- Reduced driving time by 25%, braking by 30%, and idling time by 40%
- It is planned to expand from the current 50 intersections to 200
> Milton Case, UK: 2,500 AI cameras installed, real-time traffic situation recognition, traffic signal control
> Malaysia applied Alibaba's City Brain, 300 traffic lights, and 500 CCTV cameras
- City Brain improved the average travel speed by 15% and detected traffic violations by 92% when applied to Hangzhou (China)
1. Implementation of user-centered warehouse management system
- It compares the warehouse item arrangement data collected by the algorithm with the batch data finally confirmed by the user to determine the state of import and export
- Product history management and report output with simple input
2. Real-time warehouse status visualization
- Real-time warehouse status from anywhere
- Intuitive and clear product information expression using images and 3D modeling
3. Data Collection & Storage & Loading Integrity Ensuring
- Collect camera and smart IoT hub operation data by MQTT
- Saving time series data to InfluxDB
- Dataization stored in NoSQL DB Alarm for movement of goods by comparing the data directly placed by the user
Due to the limitations of field learning and the lack of professional training personnel,
there is the demand for an education method in the extended reality that allows realistic experiences
Supporting simulation learning methods for nurturing experts in industrial fields by utilizing XR (eXtended Reality) & HMD (Head Mounted Device)
Implementation of education using XR and MR technology within a cross-platform-based real classroom in order to realize education that is more effective than basic automobile maintenance education and has a sense of reality due to the nature of the field
