At&T Inc. has selected a new technology standard to support the telecommunications giant's ongoing rollout of its AT&T U-verse-branded services.

The company chose HomePNA 3 technology to be integrated into television set-top boxes developed by AT&T vendors Scientific Atlanta, 2Wire Inc. and Motorola Inc. AT&T chose the technology after extensive testing by AT&T Laboratories.

CopperGate Communications, a Challenge Fund II portfolio company, will be providing the chip sets that power the technology to AT&T's vendors.
