Indoor navigation refers to the use of technology and tools to help individuals navigate and find their way within indoor spaces such as buildings, malls, airports, and other structures. Unlike traditional navigation methods that rely on outdoor landmarks and GPS signals, indoor navigation utilizes a combination of sensors, Wi-Fi, Bluetooth, and other technologies to provide accurate and real-time guidance. This allows individuals to easily locate specific rooms, stores, or points of interest within a building, making it a valuable tool for both personal and commercial use. With the rise of smart buildings and the increasing complexity of indoor spaces, indoor navigation has become an essential tool for efficient and seamless navigation in modern environments.
