According to The Telegraph, users could stream music without the need of a WiFi network wih the help of the new upgrade.
The site writes:
“Sources familiar with the iPhone-maker’s plans said that Apple wants to improve the AirPlay wireless music streaming technology, which currently requires Airplay speakers and a WiFi network. The new version will require just speakers or a hifi and an iDevice; the iPhone, iPod or iPad would form its own network to allow a direct connection and music playback.”
The name “AirPlay Direct” is not set to be the final and could be changed until the September 12 Apple event when it is rumored to be introduced.
The reason for bringing an update to AirPlay is the new smaller dock connector.
As Apple plans to implement a smaller dock connector across its entire iOS lineup, current stereos using the 30-pin port won’t be compatible with the new devices.
