Auracast – The new Bluetooth Generation

Up to now, Bluetooth only allowed connection of two devices. The new standard with the resonant moniker Auracast is set to change that – offering many new possibilities for trams. By Ruben Vorwald

The Bluetooth Special Interest Group (Bluetooth SIG) unveiled the new standard called Auracast, with which any number of listeners can receive an audio signal within the range of a transmitting device. This was not possible to date as the conventional Bluetooth standard only allowed coupling of two devices. 

To receive Auracast, however, you need more than a Bluetooth headset. Like WLAN, the desired Auracast must first be selected via smartphone. This audio track is then played back via the desired output path, whether wired or wireless.

For our treasured trams, Auracast offers further barrier-free access possibilities. The new technology can be used to aid the hearing-impaired by playing stop announcements, tips and information directly via a hearing aid. A separate metro radio is also thinkable if no other signal can be received underground.  

Auracast can also be used for touristic purposes. Trams could offer an audio guide, providing information on the sights to the left and right of the cabin, turning tram travel into a mini sightseeing tour. I, myself have often wondered which time-honoured buildings I am passing when travelling on a tram. That’s where an Auracast would be ideal, don’t you agree? 

What do you think? Can you think of further uses for Auracast? If so, drop me a line. Let our minds run free.
