How Does Indoor Positioning Technology Work?

Applied Tech Review | Thursday, May 12, 2022

There has been a major evolution in indoor location technology, from traditional compasses to smartphone GPS.

Fremont, CA: Location tracking has become so pervasive that it is nearly impossible to envisage a world without it. Utilizing GPS technology for outdoor navigation is crucial to our daily lives. As valuable as GPS devices are for outdoor tracking, they have never worked inside. This needs indoor location technology or indoor GPS to assist individuals in locating inside spaces. From the use of lodestones for outdoor navigation to the use of indoor positioning technology on smartphones for inside navigation, positioning technologies have undergone a radical transformation.

How does indoor positioning technology work?

Indoor positioning technology and global positioning systems are vastly distinct. Indoor navigation refers to the process of navigating within a building using an IPS (indoor positioning system). An IPS is a network of devices, which is used to precisely find or guide individuals within structures such as airports, parking garages, underground areas, schools, hospitals, resorts, and shopping centers.

There are numerous ways, strategies, and gadgets utilized for indoor navigation, all of which revolve around mobile devices. Smartphones today contain Wi-Fi, Bluetooth, digital cameras, and clocks, all of which can assist in transmitting data to strategically positioned beacons within a given geographical area. The term "indoor positioning technology" is all-encompassing and may be utilized in nearly every business, including commercial, military, retail, and inventory management. Although there are numerous commercial solutions available, there are no standardized indoor navigation platforms yet. The installation process of an indoor navigation platform is instead customized to the customer's spatial dimensions, precision requirements, and budgetary restrictions. IPSs rely on various indoor technologies, such as distance measuring to adjacent fixed anchors, magnetic positioning, and dead reckoning. They either actively find a mobile device or give ambient location or environmental context so that an iOS or Android device can detect its location.
