Optimized for logistics control of shipments to every corner of the country
First applied to a specialized specimen transportation company, scheduled to be applied to approximately 30 medical foundations in the future.

KT announced that it has launched a 'cold chain' service utilizing the commercially available nationwide IoT LTE-M and GiGA IoT platform.

'Cold chain' service monitors changes in delivery status and quality of temperature-sensitive products in real time from loading to unloading, making it suitable for high-value logistics markets requiring sorting and packaging, such as blood, specimens (materials needed for testing, also known as test materials), and agricultural and marine products.

KT has applied its LTE-M network, which ensures nationwide coverage and superior quality, to cold chain services that require the preservation of inherent quality until delivery to the customer. In addition, by utilizing the GiGA IoT vehicle platform specialized for mobile logistics, it has enhanced the convenience of integrated control by enabling easy real-time monitoring via smartphones.

The IoT device serving as the foundation for the 'cold chain' service was developed by Sammi Information Systems, a company specializing in the manufacturing of industrial computers and system development. Instead of using tag-based devices such as RFID currently available on the market, an LTE-M device was embedded in the exterior of the sample box to enable real-time monitoring.

KT and Sammi Information Systems conducted several months of field tests and terminal verification tests to ensure that the LTE-M device achieves the quality level of existing mobile phones. The actual LTE-M device implements a low-power design that allows it to be used for about a week on a single charge, despite frequent use for checking delivery status, such as location reporting and temperature reporting.

Market expansion is expected in cold chain distribution for live fish and horticultural products, as well as in the high-value logistics market.

The 'Cold Chain' service will be first commercialized through Shinil Delivery, a company specializing in specimen transportation, and is expected to manage the safe transportation of temperature-sensitive logistics such as specimens, blood, and medical equipment. KT plans to continuously enhance additional features and expand their application to approximately 30 medical foundations in Korea.

Kim Jun-geun, Head of KT’s GiGA IoT Business Unit, stated, “Based on KT’s proven network, we plan to gradually expand into areas requiring cold chain services, such as specimens, live fish transportation, and horticultural crops.”
