AT&T's Eslambolchi said his company would be investing in optics, broadband, and wireless and is looking to integrate voice and data at the edge of the network.
"It's not really the core of the network we're investing in, it's at the edge of the network," he said.
Eslambolchi, commenting on the potential for deploying wireless networking as last-mile connection method, said wireless currently lacks the speed needed for this. But in two to three years, speed will improve dramatically, he said.
Kriens, commenting on the economic slowdown in the technology sector, said, "We're going to see fallouts and we're going to see failures," but "we're going to see more business in bandwidth and services."
