Here's a look at seven 4G smartphones that goes past the marketing hype to see what to really expect from the devices and networks
Motorola ATRIX 4G
Why it’s relevant: The Atrix's most interesting feature is its ability to integrate its screen, applications and capabilities to a desktop computer. AT&T offers the ATRIX along with a laptop dock to let users hook the smartphone up to a big-screen monitor and a physical keyboard.
Like all other "4G" devices on AT&T and T-Mobile, the ATRIX 4G uses HSPA+, an advanced version of the GSM-based 3G HSPA standard that delivers significantly higher speeds than its predecessor. Whereas older HSPA networks would typically deliver mobile download speeds of under 1Mbps, tests have generally delivered download speeds in the 2Mbps to 4Mbps range.
