"Rooftop Base Station Measured with AR" KT Develops 'Base Station Twin'

[Asia Economy Reporter Koo Chae-eun] KT has developed a solution called 'Base Station Twin' that measures information on the construction of 5G base stations (antennas) located far away using augmented reality (AR) technology. This solution helps engineers build 5G networks in a safe environment by utilizing AR.

On the 19th, KT announced that with the development of the 'Base Station Twin' solution, engineers can now determine the angles of base stations without having to climb rooftops themselves. Previously, engineers had to directly approach the equipment to measure base station construction information. This method took a lot of time and required working in hazardous environments such as building rooftops.

KT's Base Station Twin solution is expected to reduce these inconveniences. It usually takes about 10 minutes for engineers to climb onto building rooftops and measure 5G base station construction information using a compass and angle gauge, but with Base Station Twin, it is possible to measure and store all values in an average of just 3 minutes. For telecom operators to deliver wireless services to customers without interruption, construction information such as the angle and height of base stations must be precisely managed. If the location or direction of a base station changes due to external factors, the wireless communication service radius may overlap with adjacent base stations or narrow, causing shadow areas.

Base Station Twin can automatically update the 5G base station construction information extracted in real time to a data storage server. Engineers can handle all tasks from measurement to recording on-site without returning to the office. According to KT's field verification of Base Station Twin, when engineers measured the construction information values of base stations located about 30 meters or more away, the average deviation was about 1 degree for the tilt angle and about 7 degrees for the azimuth angle.

Lee Jong-sik, Head of the Infrastructure Research Institute at KT Convergence Technology Institute (Senior Executive Director), said, “Base Station Twin is the result of researchers' continuous efforts to develop differentiated technologies to provide top-tier 5G quality.” He added, “To enhance customers' perceived 5G service quality, we plan to actively apply various latest technologies, including remote base station management technology through digital twin construction and artificial intelligence (AI) technology, to 5G network operation tasks in the future.”
