Although the company is calling its HSPA+ devices "4G," AT&T Mobility CEO Ralph De La Vega announced here that AT&T will also of its legitimately 4G LTE network, saying that the carrier will begin building the network this year and will complete the project in 2013. AT&T LTE service will start surfacing in certain markets in the middle of 2011, he said.
