As the importance of location-based services has grown in recent years, many people are also aware of indoor location services that can replace GPS indoors. Beyond the technology that can only estimate approximate locations, I would like to introduce in detail the indoor positioning technology that is developing with increasing accuracy.

What is an indoor positioning system?

An indoor positioning system is a technology that tracks the location of a moving object in a building or in an indoor environment. As buildings become larger and more complex, and indoor activity time gradually increases, indoor positioning technology is implemented in various ways and technologies.

What techniques and methods do you use?

Major indoor positioning techniques and methods include.

  • Wi-Fi-based technology
    Use Wi-Fi signals to locate devices. If you know the location of the Wi-Fi access point, you can determine the location based on the device’s corresponding point, distance, and signal.

  • Beacon technology
    A beacon is a small device that uses BLE technology to stagnate location information on peripheral devices. Beacons can be used to measure the user’s location.

  • Inertial Navigation System(INS) technology
    It uses the same sensors as accelerometers and gyroscopes to track your movement patterns and extract your location from them. However, errors can occur over time.

  • Ultra-wideband(UWB) technology
    UWB technology is a wireless technology that enables very limited distance measurement and can be used for indoor location-side locations.

What field is it used in?

Indoor positioning technology plays an important role in various fields.
There are some examples below.

  • Location-based services
    Indoor positioning technology is indoor navigation and location-based technology using mobile devices such as smartphones, tablets, and smart watches. This allows you to identify the exact location of users within buildings such as shopping malls, airports, museums, and hospitals to provide services such as directions, location information, and store search.

  • Responding to safety and emergency situations
    Indoor positioning technology enables rapid response in emergency situations. Accurate location information can be provided to rescuers and emergency relief teams to support lifesaving and safe evacuations in situations such as fires and earthquakes.

  • Smart Home and IoT
    You can manage and control your smart devices in your home. Devices such as smart lights, security cameras, and robot vacuum cleaners can be automatically operated or adjusted depending on the user’s location and environment.

  • Manufacturing and logistics
    Indoor positioning technology is used to track and manage products, inventory, and resources within factories and warehouses. This will help improve logistics and production efficiency, and reduce errors.

  • Distribution and retail business
    Indoor positioning technology can track customer movements and purchasing patterns within the store. Floating population data in indoor space helps with commercial area analysis.

Indoor positioning technology is very important in modern society and is actively used in various fields. If you have any questions regarding indoor positioning technology or indoor maps, please feel free to contact us.
