Forget Wi-Fi for your Chromecast connectivity needs, as Google has found a more interesting way to pair the dongle with nearby devices for streaming purposes, GigaOm reports. The Chromecast team has figured out how to use inaudible ultrasonic sounds to pair the entertainment device with supported smartphones and tablets. The new pairing feature will do away with the mandatory Wi-Fi connection that’s currently needed to control the Chromecast from a mobile device, allowing Chromecast owners to share control of their dongles with family and friends without laborious setups. The TV-connected Chromecast will emit a unique ultrasonic sound through the TV’s speakers, which will be picked up by nearby mobile devices, but not humans. This is how a connection is established.
