Connects nearby devices without Bluetooth, Internet. Presenting Google Wi-Fi Aware !

Google has found a new way to keep nearby devices and users connected as it has launched its "WiFiNanScan App".

Google has spent years developing a very quick and easy way to share content between two Android devices, and it's finally cracked the problem.

So Hi there, This is Mayank and here in this blog, you will get to know about Google's new Wi-Fi Aware App.

Daniel Marcos Schwaycer, a Product Manager on Android, announced Nearby Share yesterday, describing it as "a platform to enable reliable and easy sharing across thousands of Android phone models and billions of people." Sharing content on Android until now has meant searching for a contact, attaching a file to a message, and sending it, but Nearby Share is meant to replace that process entirely.

Nan: Neighbor Awareness Networking

In case you don't know, wi-fi aware is Neighbor Aware Networking (NAN) that let smartphones running on android 8 and above version to "discover and connect" directly to each other without any other type of connectivity between them."
The API discovers the nearby devices and creates a network for sharing data or sending short messages.
As per Google, this wifi network-aware support "higher throughputs rates across longer distance than Bluetooth connections."


What is the WifiNanScan App and how does it work?

WifiNanScan App is designed as a research, demonstration, and testing tool for developers, vendors, universities, and more.

-Using this app, users can send a document to a printer without the need to first log onto the network.

-The app lets users reserve a restaurant and view its menu while walking by it without an internet connection whether it is open or closed.

-The app also helps to automate and timestamp the check-ins and roll-call in a school.

-Using this app, users can replace their physical ID such as a driver’s license or passport with mobile identification. This helps travelers to easily pass the airport security, customs, and immigration process, traffic police without requiring to present a physical ID.

The WifiNanScan App (made by ‘Developed with Google’) Play Store listing gives us a bit more idea about it. “With this app, it is possible to obtain a distance measurement with a precision of about 1 meter with phones up to 15 meters apart. Developers, OEMs, and researchers can use this tool 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 WiFi Aware/NAN API,” stated the listing.

It is worth adding that some enhancements have been made in Android 12 as well when it comes to Wi-Fi Aware. It includes efficiency improvements and addressing lost connections.
