KT Successfully Demonstrates First NB-IoT Service on LTE Network
Published2016.09.20 15:03KT and Daejeon City Pursue Cooperation to Provide NB-IoT-Based IoT Services
KT announced on the 20th that it has demonstrated various IoT services using NB-IoT technology on a commercial LTE network for the first time in the world in cooperation with government agencies and domestic and international partners, including Daejeon City, Nokia, Kolon Industries FnC Division, and Intel.
KT collaborated with Kolon Sport, an outdoor brand of Kolon Industries' FnC Division, to develop an 'IoT Safety Jacket (prototype)' equipped with Intel's NB-IoT module in a hiking jacket, and demonstrated that IoT services are possible with low power consumption and low capacity even in emergency situations or on hiking trails where communication signal strength is weak.
NB-IoT (Narrow Band IoT) is an IoT standard technology that uses a narrow bandwidth of 200 kHz to support low transmission speeds and wide-area services of more than 10 km. As it was standardized last June, it is evaluated as a low-cost, low-power, low-capacity IoT service specialized for exchanging only small amounts of information.
The 'IoT Safety Jacket' demonstrated this time is designed to automatically operate by detecting abnormal movements of the person in distress via an axis sensor, even in distress situations during hiking where voluntary reporting is impossible.
In the event of a distress situation, a distress alert message sent via an NB-IoT communication module is linked with the LTE commercial network and KT's IoT platform 'IoTMakers' to transmit the status and location of the person in distress to the control room. In addition, the alarm LED and sound sensor built into the jacket activate automatically, allowing rescue teams to easily locate the person in distress even at night.
In addition to this, KT also showcased an 'IoT Smart Tent (prototype)' that detects fires and notifies the control room, and prevents theft and fire accidents inside the tent through human and fire detection sensors.
Following a technology demonstration in August that integrated Nokia's base station and NB-IoT dedicated core network equipment in a commercial LTE network environment, KT has now succeeded in a real-world service demonstration using Intel modules and Kolon Sport's mountain-related products, enabling it to provide various IoT services based on LTE-M and NB-IoT on a single integrated LTE network.
Meanwhile, KT plans to pursue cooperation with Daejeon City on public IoT service projects utilizing NB-IoT technology, and will sequentially commercialize IoT services in various fields, ranging from safety and security services for individual customers to asset management and smart factory services for corporate customers.
"Through this world's first NB-IoT service demonstration, we were able to confirm not only the technical value but also the business value," said Kim Hyung-wook, Head of Platform Business Planning at KT. "We will build a nationwide NB-IoT network early and collaborate with over 500 partners within the GiGA IoT Alliance to introduce innovative services and lead the expansion of the new IoT market."
Song Cheol-un, Director of Information Technology at Daejeon City, stated, “Daejeon City plans to expand IoT services into the smart city and environmental sectors in cooperation with KT based on NB-IoT,” adding, “The world’s first demonstrated Internet of Things service will foster various local businesses and improve the quality of life for citizens."I hope it will serve as a driving force," he stated.
"This demonstration is a very important achievement for our IoT partnership with KT," said Andrew Cope, Country Manager at Nokia. "We will work with various partners to prove that NB-IoT technology enables public safety and new IoT services."

LTE-M or LoRa? The War to Build 'Commercial Networks' for the Internet of Things Within the Year
As IoT dedicated networks specialized for Internet of small Things (IoST) are being rapidly built, related IoT services are expanding accordingly. Internet of small Things (IoST) is a transmission technology characterized by low cost, low power consumption, and low capacity, capable of operating on batteries alone without requiring small data transfers and constant power supply. This is because not all things exchanging data through the internet necessarily require expensive ultra-high-speed networks. Accordingly, major domestic telecommunications providers are expanding their IoST network construction and successively launching IoT services based on these networks. IoT dedicated networks specialized for IoST initially highlighted LTE-M technology utilizing existing networks, but low-power long-distance communication technology (LPWA) for the IoT field is also gaining attention. LPWA technologies such as LoRa, NB-IoT, and SigFox are competing in this space.

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
