"AT&T has formally announced plans for deploying its 7.2 Mbps mobile data service upgrade this year, which will support faster iPhone models expected to be released this summer.
AT&T said the upgrade to High Speed Packet Access (HSPA) 7.2 technology, which delivers theoretical peak speeds twice that of the company’s current 3G network, will continue through 2011. Next year, the company will also begin trials of LTE (Long Term Evolution), with deployment of that technology to begin in 2011. LTE plans to eventually reach theoretical peak speeds of 20 Mbps.
