KT Succeeds in NB-IoT Communication Demonstration in LTE Commercial Network Environment
Published2016.08.31 16:10IoT Services Possible in Locations with Weak Signal Strength Such as Underground Parking Lots and Mountain Trails
KT announced on the 31st that it has successfully demonstrated key NB-IoT technologies based on 3GPP standards in an LTE commercial network environment for the first time in the world in collaboration with Nokia.
NB-IoT (Narrow Band IoT) is an IoT standard technology specialized for small data communication between remote, low-power consuming objects using a narrow 200 kHz bandwidth compared to existing mobile communication methods such as LTE and 3G. With very affordable module pricing, it is well-suited for various Internet of Small Things (IoST) services such as smart metering (remote meter reading) and smart street lights.
Following joint technical verification conducted at Nokia Labs in June after the completion of NB-IoT standardization at 3GPP, KT successfully demonstrated NB-IoT technology interoperability utilizing Nokia's base stations and NB-IoT dedicated core network equipment in an LTE commercial network environment, achieving narrowband (200 kHz) communication and maximizing coverage through power boosting technology.
Through this technical demonstration, KT proved that NB-IoT can amplify signal strength with low power due to its frequency characteristics, enabling service in areas where coverage was previously difficult such as underground parking lots and remote mountain trail areas, and can be immediately applied in existing LTE commercial networks. KT forecasts that IoT services through NB-IoT will be activated much more rapidly.
Going forward, KT plans to complete NB-IoT nationwide network deployment within the year following service field trials in the latter half, and plans to take the lead in the Internet of Small Things market by continuously developing services in various sectors including NB-IoT-based smart metering, safety and security services, asset management, smart factories, and smart cities.
Seo Chang-seok, Senior Executive Director of KT's Network Strategy Division, stated, "KT plans to complete all preparations from technical verification to network deployment by year-end for early commercialization of NB-IoT in the first half of next year," and added, "Going forward, we will strengthen our technological leadership in the IoT field through close collaboration with global manufacturers including Nokia."
