South Korean operator KT is using internet of things (IoT) and big data analytics to monitor and analyze air quality 24 hours a day, 365 days a year. The initiative supports government-led efforts to reduce fine dust levels, The Korea Times reports. Under its "Air Map Korea" project, launched in September 2017, KT has established a fine dust observation network at 1,500 spots such as base stations and public telephone booths nationwide.
KT has also deployed an integrated fine dust control center at the KT Intelligent Network Support (INS) unit in Gwacheon, Gyeonggi Province. According to Kwon Hye-jin, head of KT’s INS unit, the company checks any errors or failures of 1,500 networks around the clock, and when a non-functional network is found, the control center indentifies its location immediately and sends technicians to the spot.
Information such as fine dust levels, temperature, noise levels and humidity, collected by the observation networks, is transmitted to the company's "Air Map Platform" every minute, and the control center manages such information in real time, Hye-jin added.
The company said its big data analytics is used to systematically manage fine dust levels as it analyzes mobile population and the volume of traffic as well as the locations of facilities that emit sources of air pollutants. The technology can also be used to see if policies designed to reduce fine dust levels are actually effective.
"We are developing a variety of measures to reduce fine dust levels based on our observation networks and big data analytics," said Lee Kwang-uk, head of the environment and safety business department at KT. "We plan to develop a mobile phone app within the year to share fine dust information with more people", Kwang-uk also said.
