High Accurate Automatic School Bell Controller Based On ESP-32 Wi-Fi

Wi-Fi Based Positioning System

 Abstract—In today’s era position of any outdoor element can be determine precisely using GPS. But in the indoor environment like house, colleges, underground construction site GPS does not work well. As now-a-days all house and colleges are equipped with Wi-Fi access point, precise position can be found out using Wi-Fi using method name Received Signal Strength Indicator (RSSI). A series of e...

Designing High Performance Enterprise Wi-Fi Networks

Use of mobile computing devices such as laptops, PDAs, and Wi-Fi enabled phones is increasing in the workplace. As the usage of corporate 802.11 wireless networks (WLANs) grows, network performance is becoming a significant concern. We have built DenseAP, a novel system for improving the performance of enterprise WLANs using a dense deployment of access points (APs). In sharp contrast with wire...

Refining Wi-fi Based Indoor Positioning

The increasing demand for location-based services inside buildings has made indoor positioning a significant research topic. This study deals with indoor positioning using the Wireless Ethernet IEEE 802.11 (Wi-Fi) standard that has a distinct advantage of low cost over other indoor wireless technologies. Most of the proposed Wi-Fi indoor positioning systems use either proximity detection via ra...

Automatic Construction of Wi-fi Radio Map Using Smartphones

Indoor positioning could provide interesting services and applications. As one of the most popular indoor positioning methods, location fingerprinting determines the location of mobile users by matching the received signal strength (RSS) which is location dependent. However, fingerprinting-based indoor positioning requires calibration and updating of the fingerprints which is labor-intensive an...
