With the WifiNan app, you can easily discover nearby devices that are using this app as-well and connect with them. Google has been working on local discovery technologies that apps can take advantage of to find nearby objects and users. It’s designed as a research, demonstration, and testing tool for developers and vendors.
The future prospect of this app can allow Android devices to connect with each other over far greater distances than Bluetooth. Making it possible to send messages to each other, or transfer large amounts of data without an internet connection.
NAN, also known as Neighbor Awareness Networking. Allows Android 8.0+ devices to “discover and connect directly to each other without any other type of connectivity between them. Devices talk to each other like on an active internet connection.
The APIs work to discover nearby devices and create network connections. That can “share large amounts of data” or send short messages. Google says this technology supports “higher throughput rates across longer distances than Bluetooth connections.
How will WiFiNan app revolutionize the world around us?
With the current status of the app. You can use it as a publisher or a subscriber to receive data and info. But just for the sake of understanding the purpose simply, users can securely send a document to a printer without first logging onto the network.
Developers and researchers can use this app to validate distance/range measurements. Enabling the development of peer-to-peer ranging and data transfer, find my phone and context-aware applications based on the Wi-Fi Aware/NAN API.
Companies can Automate and timestamp check-ins by the associated device that walks in through the door. Customers can easily view a restaurant menu. And be able to make a reservation while walking by without an internet connection.
The possibilist are endless and the exclusion of an internet connection automatically secures the chatter between devices to a certain extent. With this app, it is possible to obtain a distance measurement between two devices. A precision of about 1 meter with phones up to 15 meters apart.
The latest WIFI-Aware upgrades in Android 11 and further improvements in android 12 WiFiNan connectivity can be expected to get further improvements.
