AT&T said that its 3G mobile broadband network will support Sling Media’s SlingPlayer Mobile app.

Sling Media, a wholly owned subsidiary of EchoStar, has developed its wireless app to make use of 3G network bandwidth and to conserve the finite wireless spectrum available to the wireless industry.

Since mid December 2009, AT&T has been testing the app and has recently notified Sling Media and Apple that the optimised app can run on its 3G network.

Ralph de la Vega, president and CEO of AT&T mobility and consumer markets, said: “Just as we’ve worked with Sling Media in this instance, we look forward to collaborating with other developers so that mobile customers can access a wider, more bandwidth-sensitive, and powerful range of applications in the future.

“Collaboration with developers like Sling Media ensures that all apps are optimised for our 3G network to conserve wireless spectrum and reduce the risk that an app will cause such extreme levels of congestion that they disrupt the experience of other wireless customers. Our focus continues to be on delivering the nation’s most advanced mobile broadband experience and giving our customers the widest possible array of mobile applications.
