AT&T, playing catch-up in the mobile broadband wars, detailed its 4G network plans today while rolling out new devices at its Developer Summit at this week’s Consumer Electronics Show.
AT&T’s will basically have two networks, one starting today based on HSPA+ technology and a new LTE network coming in 2011 and beyond. AT&T has completed the upgrade of its 3G network to HSPA+ in almost all of its markets, the company said.
Motorola Mobility CEO Sanjay Jha demoed the first Webtop-enabled handset, the Atrix 4G, which he billed as the most powerful smartphone in the world. HTC CEO Peter Chou introduced his company’s new Inspire 4G, the first U.S. device to make use of HTC’s new Sense cloud-services and context-aware user interface. Samsung President H.K. Shin unveiled the Samsung Infuse 4G, which he billed as the thinnest yet largest-screened (4.5 inches) Android smartphone ever built.
Though those three devices were featured, de la Vega promised AT&T would deliver 20 “4G” devices in 2011, including HSPA+ and LTE tablets, laptop cards, netbooks and handsets.
