GPS reception is usually non-existent inside buildings; hence the need for other positioning technologies. One option is to use indoor navigation although it is only possible with automatic positioning. The technology is used as a client-based application meaning that the position is determined directly on a user’s Smartphone. You require an app since the location is determined via beacons or Wi-Fi. Also, there is a feedback channel for sending push notifications.

Use of Wi-Fi

Indoor navigation with a Wi-Fi gives 5-15 meter accuracy. The major advantage of Wi-Fi is that you can use the available infrastructure e.g. routers and customer hotspots. All you need is to activate your Wi-Fi on your Smartphone. You don’t need a connection for this, but if you are using client-based positioning via Wi-Fi, you cannot use Apple devices.
Use of Beacons

The use of beacons for indoor navigation is a widespread phenomenon since Bluetooth transmitters function across different platforms with 1-3 meter accuracy. The common types are Beacon from Apple and Eddystore from Google; the two operate using the BLE standard but are energy efficient. The devices have a battery life of about three years, and the cost depends on the functional scope and type of batter. A beacon needs replacement after every 7-10 meters depending on the accuracy level. Beacons offer high-level accuracy and flexibility making them quite popular among users.
Use with Ultra-Wideband

Indoor navigation with ultra-wideband has some significant benefits in industrial applications. It has an accuracy level of 10-30 centimeters which makes it better than working with a Wi-Fi or beacon. Although latency is minimal, you can measure the difference in height more accurately.
Various Applications for Indoor Navigation

In most cases, an indoor application is requited when navigating through multifaceted buildings. Nonetheless, it can also be used in other unique visitor services. The functions come alongside the navigation function, and they include:

Train stations to inform visitors about current delays and in tracking changes.

In offices for booking meeting rooms, invitation management, colleague finder, and cafeteria layout are excellent functions.

In the retail industry- location based advertisements, car finders, and coupons and location-based marketing offer helpful features.

Hospitals integrate the booking of extra services. It can include a calendar with treatment schedules and a barrier-free routing into the patient’s app.
