Google’s new app “WifiNanScan App” can now connect nearby smartphones and users without Bluetooth. As per the search giant, this Wi-Fi Aware supports “higher throughput rates across longer distances than Bluetooth connections.”
This mobile application can measures distance between two smartphones using the Wi-Fi Aware protocol. Wi-Fi Aware is also known as Neighbor Awareness Networking (NAN). This protocol allows all devices running Android 8.0 and above to “discover and connect directly to each other without any other type of connectivity between them”. The WifiNanScan app is designed as a research, demonstration, and testing tool for developers, vendors, universities, and more. It lets you use NAN to know the distance between two devices.
