Google releases ‘WifiNanScan App’ on Play Store to measure distance between phones – 9to5Google

Wi-Fi Aware— also known as Neighbor Awareness Networking (NAN)– allows Android 8.0+ gadgets to “find and connect directly to each other with no other kind of connectivity between them,” like an active web connection. The APIs work to develop and discover nearby devices network connections that can “share big quantities of information” or send out brief messages.

Google says this innovation supports “greater throughput rates across longer distances than Bluetooth connections.” Possible use cases promoted by the Wi-Fi Alliance include:

  • Securely send a file to a printer without very first logging onto the network
  • View a dining establishment menu and make a reservation while walking by without an internet connection, even when the dining establishment is closed
  • Automate and timestamp school check-ins and roll-call
  • Improve airport security, custom-mades, and immigration processing flows using mobile recognition (ID) such as a driver’s license or passport without requiring travelers to provide a physical ID

Earlier this week, Developed with Google released the WifiNanScan App (Play Store) to demonstrate how you can use NAN to get the distance in between 2 devices:

With this app it is possible to obtain a range measurement with a precision of about 1 meter with phones approximately 15 meters apart. Developers, scientists and oems can utilize this tool to validate distance/range measurements enabling the advancement of peer-to-peer ranging and information transfer, discover my phone and context-aware applications based upon the WiFi Aware/NAN API.

It compliments the WifiRttScan App released 2 years back to utilize Wi-Fi Round Trip Time for indoor positioning as an option to GPS.

In Android 12, Google made some improvements to Wi-Fi Aware, including effectiveness enhancements and attending to lost connections.

For the past several Android releases, Google has been working on regional discovery innovations that apps can benefit from to find nearby objects and users. Its latest contribution is the Google Play release of a “WifiNanScan App” for developers to explore Wi-Fi Aware.
