KT's Air Map Korea project is transforming into a national platform providing customized fine dust information that can be accessed by anyone, anywhere, anytime in South Korea.
KT held an Air Map Korea press conference at KT Square in Gwanghwamun, Seoul, and announced on the 18th that it would provide a lifestyle guide that would allow anyone to check fine dust information in real time and prevent damage using KT's platform.

The Air Map Korea Project is a social contribution activity by KT that supports the establishment of fine dust policies through IoT solutions and big data analysis. KT is conducting a fine dust reduction demonstration project by establishing a comprehensive response situation room and setting up routes for water sprinklers and dust collectors in cooperation with local governments across the country through its own measuring network of approximately 2,000 points built over two years.


Air Map Korea application provides real-time fine dust information.
KT's Air Map Korea application provides a function that allows users to compare fine dust levels by region as well as by their current location.
By setting a location and time in "Schedule Management," you can receive regular updates on fine dust forecasts for your designated area. For added convenience, we also provide a lifestyle guide that combines fine dust data with daily activity information, such as "laundry," "exercise," and "car wash" indices, based on fine dust levels.

Users can also choose between 7 or 4 levels of air quality standards based on the domestic Ministry of Environment and WHO recommendations. In the future, we plan to introduce a 'safe school route, pedestrian route' service that combines the mobile population of telecommunication companies and public information.

Air Map Korea can be downloaded for free from Google Play Store, One Store, and Apple App Store, and can be used regardless of carrier.

KT's Air Map Korea application provides real-time weather and fine dust information at 'the closest location to me' and 'breathing height.'

KT has installed approximately 2,000 measuring stations nationwide, and the spacing between the measuring stations in Seoul has been set at approximately 1㎢, allowing for the verification of living area information in nearby areas. KT is collaborating with the Korean Society for Atmospheric Environment to ensure measurement data accuracy.


Combining the AirMap platform with big data to analyze fine dust diffusion patterns and provide reduction solutions.
KT has launched the Air Map Korea mobile application, which provides personalized fine dust information so that all citizens can utilize the Air Map Korea project. It has also announced plans to ▲provide fine dust predictions and lifestyle guides based on big data analysis and ▲expand a seamless measurement network by introducing mobile observation sensors.
According to an analysis of information observed and collected by KT at its fine dust measurement station, on January 11, when high concentrations of fine dust occurred consecutively, the fine dust levels in Seoul differed by more than twice in each region despite being at the same time.

On days when fine dust levels fluctuate significantly, minute-by-minute figures showed differences of up to 87㎍/ ^m3 even within an hour. This section shows that it is important to receive fine dust information based on the living area and to identify the spread path through real-time forecasts.


AI voice guidance improves access to information for vulnerable groups.
KT confirmed through big data analysis that even on days when fine dust levels were 'bad', the number of pedestrians aged 65 and older in city parks, where vulnerable groups are concentrated, did not decrease.

Despite the equally poor conditions in mountainous areas on days with high levels of fine dust, the number of hikers remained unchanged. The study also identified temperatures at which fine dust concentrations worsen in winter (-1℃: poor, 7℃: very poor) based on daytime highs, highlighting the need for careful management of outdoor activities.

Based on this, KT plans to actively support the installation of fine dust signal lights on hiking trails, parks, and other locations in cooperation with relevant organizations to make fine dust-related information more readily accessible. It also plans to provide a lifestyle guide based on big data analysis to encourage all citizens to make efforts to reduce fine dust.
In this way, KT also provides video and voice guidance services through Olleh TV and Giga Genie to improve information accessibility for the elderly and others who are not familiar with using mobile devices. By simply asking, "Genie! Tell me about fine dust," you can receive on-screen and voice guidance on the fine dust status and concentration at your residence and destination, as well as lifestyle precautions.

Even within the same city center, there was a difference of about 30㎍/ ^m3 depending on road width and the number of parked and stopped vehicles. Even though the traffic volume on a 10-lane road was about three times that of a 4-lane road, the fine dust level was actually lower. Based on this, a test on fine dust generation according to gear shifting showed that shifting from drive mode (D) to park (P) or neutral (N) when the vehicle was stopped had a 20% reduction in fine dust concentration. This confirmed that efforts to reduce fine dust can be made by correcting driving habits.

While preparing for the Air Map Korea project, KT also found a solution that would improve energy efficiency in managing fine dust.

We collected and analyzed data on the effects of air conditioning operation on air quality at a busy train station. The results showed that while higher fine dust levels were associated with improved air quality, there was no significant difference when fine dust concentrations fell below a certain level (50㎍/ ^m3 based on a set schedule (05:00-23:00). Efficient air conditioning operation (from 18 hours to 15.8 hours) is expected to result in a 14% energy efficiency increase, equivalent to 2.2 hours.


We will secure a 10,000-unit measurement network by the second half of the year to improve accuracy.
KT will build a seamless fine dust measurement network by adding 500 additional measurement stations, including approximately 2,000 external measurement stations established across the country, and deploying approximately 7,000 mobile observation sensors. First, we plan to distribute 'smart safety helmets' equipped with small air quality monitors to field workers after a pilot operation.

The smart safety helmet was developed by Goodbro, a childcare company under the Gyeonggi Creative Economy Innovation Center. It has a small sensor attached to the helmet that can collect air quality data around the worker's respiratory system. When a dangerous level of fine dust concentration is measured, a linked application provides guidance on wearing a mask, and there is a safety helmet wearing notification function to prevent disasters.
In addition to the smart safety helmet Goodbro, KT is committed to creating an ecosystem by cooperating with related companies such as traffic lights (UClab), air purifiers (LG Electronics), air conditioners and air showers (Shinseong E&G), Ecotree, and reduction benches.

Since December 2018, KT has been working with the United Nations Environment Programme (UNEP) to promote the global expansion of the Air Map Korea project.

This project is to select, design, and construct measurement equipment locations based on data analysis, including floating population, to establish an optimal measurement network through selection of candidate countries with UNEP.

KT will also provide consulting services for Environment Live, a UNEP environmental data knowledge platform, based on its know-how.

KT Future Platform Business Division Head Lee Dong-myeon said, “The KT Air Map Korea project is now moving beyond Korea to become global,” and added, “Through the launch of the mobile application, we will check the fine dust information in the area where I breathe and continuously suggest ways to reduce fine dust in my daily life and prevent damage. At the same time, we will take the lead in improving the global environment through cooperation with international organizations.”
