Qualcomm Atheros Introduces First Generation of Wi-Fi Display-enabled Connectivity Solutions

Qualcomm Atheros today day announced the availability of its first generation of Wi-Fi Display-enabled peer-to-peer connectivity solutions. This first set of Qualcomm Atheros' solutions will serve as the foundation for a new generation of interoperable consumer electronics that allow users to easily share content from device to device without the need for an Internet connection, network or access point. Wi-Fi Display is an industry standard devised by members of the Wi-Fi Alliance that enables sharing of the screen image or audio content of one device simultaneously on another nearby device, including simple and secure device discovery and pairing.

For example, the Web page appearing on a computer screen can be shared on the screen of a nearby enabled TV. A typical use case could enable content on one smartphone screen to be shared with a nearby media tablet. The technology underlying Wi-Fi Display allows a direct, peer-to-peer wireless connection known in the industry as Wi-Fi Direct.

The implementation of Wi-Fi Display will be particularly useful for devices like smartphones and tablets, allowing users to consume content on nearby consumer electronics with larger screens. Wi-Fi Display technology leverages the 5 GHz wireless band, which offers up to 24 non-overlapping channels (or the 2.4 GHz band, which offers three non-overlapping channels) for relatively interference-free transmission of latency-sensitive media content. Wi-Fi Direct technology is the foundation for the Qualcomm Atheros Wi-Fi Display implementation, making Wi-Fi Display easy to enable and use. The specification keeps data safe and secure by using the latest Wi-Fi Protected Access II (WPA2) security mechanisms and provides effective, industry-supported content protection mechanisms that free consumers to share content securely between devices. Wi-Fi Display certified devices also eliminate the need for consumers to use cumbersome cables.
