Survey on Wireless Fidelity (Wi-Fi) Based Indoor Location Technology for Mobile Devices

Implementing destination operations in a confined area may be revolutionized by indoor localization if the current inadequacies can be solved. Consequently, the development of a widespread indoor localization system (ILS) is now required. Cell phones and Internet-based indoor navigation could be used to achieve widespread use because cellphones are widely available and most buildings have WiFi. WiFi signal strength varies greatly depending on the environment and the configuration of the devices that use it. Because of this, a universal ILS that is widely accessible and does not need specialist hardware support remains a long way off in the future. Thus, this research examines the current level of WiFi-based algorithms for indoor positioning and their potential to be used in a wide variety of contexts. As a result, an ILS that relies on WiFi for availability is the fundamental objective of this study, and it aims to identify and recommend future research priorities. Using a real-world dataset, some experiments have been done to show how hard it is to put this kind of system into place.
