A global positioning system (GPS) is widely used to determine a location anywhere in the world. It works best when there is an unobstructed line of sight to four or more satellites. This results in relatively weak signals inside structures, such as buildings. An indoor positioning system (IPS) is used to determine a location inside buildings by taking advantage of infrastructure such as Wi-Fi access points that are present at fixed locations and transmit signals.
There are several commercial systems available that use various technologies, including Wi-Fi and Bluetooth, for providing IPS. Vendors of such systems need to survey the interior space of buildings to enable indoor positioning. The precision of indoor location is dependent on the technology used. Bluetooth-based IPS is generally more accurate and reliable than Wi-Fi-based IPS.
ArcGIS Indoors for Android supports bluetooth-based IPS provided by Indoo.rs.
Mobile operating systems have location-service-specific settings that determine the most accurate positioning in an indoor space. The following settings are recommended for a good IPS experience:
Turn on the Location setting and set Location mode to High accuracy. Turn on the Scanning setting for Wi-Fi and Bluetooth.
If your organization is using Indoo.rs IPS, the mobile map packages must include a specific set of configurations related to it.
