Google’s Nearby 2.0 released, enabling offline communication, media sharing, and more
Think of it like NFC on steroids, where only proximity is needed rather than a tap, and the amount and size of data is essentially limitless. Such use cases could include sending a message to those in a subway station to inform them of delays, media hubs from which people can stream music or movies to their device, or simply for creating a chat hub at a public venue - all without touching the internet.
In fact, similar implementations are already being built. The Weather Channel is implementing Nearby in its app to help spread urgent weather warnings to those in data-deficient areas, while Hotstar is enabling the ability to share media from its app without an internet connection, and GameInsight is using the technology to run entire games offline.
Unfortunately, the Nearby-powered private driveway/parking spot renting app Google spoke of at I/O has yet to be created. We'll be waiting for that one with baited breath, Google.
