AT&T’s Cingular Wireless unit announced plans on Monday to use Qualcomm’s new MediaFlo wireless network for the delivery of live television programming to wireless phone subscribers by the end of this year. The agreement follows on a similar arrangement between Qualcomm and Verizon Wireless, which intends to use MediaFlo to launch its V Cast television service to customers during the first quarter of this year. Other U.S. carriers, such as Sprint Nextel, T-Mobile and Alltel, have tested MediaFlo or plan to do so in the near future. Already, Qualcomm has lined up a variety of content partners, including CBS and Fox television networks, Viacom’s Comedy Central and NBC Universal, that will provide live programming for the MediaFlo network. Although details of Cingular’s agreement were not disclosed, a spokesman confirmed that two of the channels offered to subscribers would be exclusive to Cingular. Sources also say that the pact deals a blow to Crown Castle’s Modeo venture, which uses a rival platform known as DVB-H to provide live television services to wireless phone customers. Although DVB-H has attracted a following in Europe, it has yet to catch on in the U.S. market. Praising the agreement, Qualcomm CEO Paul Jacobs explained: “we share with AT&T an exciting vision of a world in which consumers have access to a high quality mobile-media experience wherever they are, whenever they want it.”
