YAKIMA, Wash. — AT&T officially rolled out the fourth-generation LTE cellular data network service this morning.

Local customers saw the LTE status as early as Friday afternoon, but AT&T officials said Monday that it was just a test.

The network rolled out after final testing was complete, AT&T spokesman Andy Colley said in an email.

Until this past weekend, most local customers had access to a network called Evolved High Speed Packet Access, or HSPA+, which offers speeds faster than the third-generation (3G) cellular data network once prevalent in the area. Though HSPA+ was marketed as 4G service, it was not as fast as LTE, which stands for Long Term Evolution.

Even under a 4G LTE network, speeds can vary greatly, but in general providers claim it can provide speeds up to 10 times faster than 3G that would allow customers to stream video and download content much more easily.
