Google today announced a new beacon technology called Eddystone along with APIs that together it hopes will make it easier for Android and iOS-powered devices and beacons in close proximity to communicate with one another. Unlike iBeacon, Apple’s take on the Bluetooth-based protocol, Eddystone is open source and designed to be easily extendable, compatible with any device which supports the use of beacons. A new API announced alongside Eddystone, compatible with iOS and Android devices and available to Android developers today (iOS support forthcoming), uses inaudible sound emitted from device speakers and heard from other devices using their microphones to determine when other smartphones and tablets are nearby so data can be transmitted between them.
