Internet of Things (Internet of Things, IoT) is becoming commonplace at a faster rate, thus the study of low-power long-distance communication is being accelerated. In addition, localization based on wireless sensor network bas been interested. Positioning using LoRaWAN boasts relatively excellent accuracy compared to other technologies, but it seems a lot of error in the nature of other wireless technologies in indoor environment. This paper correct TDOA localization result using in advance constructed TDOA correction database in such indoor positioning.
