AT&T testing HSPA+ network in Chicago

An AT&T spokesperson recently confirmed that the carrier has been running trials in Chicago that test upgrades to its HSDPA network that would offer data speeds of 7.2Mbps or more. AT&T previously confirmed that it would be using LTE^(INFO) for its 4G network, but is also planning to update its HSDPA^(INFO) network to the faster HSPA+^(INFO) technology first.

HSPA+ not only increases downlink data connection speeds up to 14.4Mbps, but also increases uplink speeds, as well, which enables faster uploading from cell phones. AT&T spokesperson Mark Siegel confirmed the tests, but declined to explain what technology was being used to achieve these faster data speeds.
