AT&T Picks Alcatel-Lucent, Ericsson for LTE Network

AT&T has tapped Alcatel-Lucent and Ericsson to deliver network equipment and related engineering services for the U.S. wireless carrier's upcoming deployment of a high-speed 4G network based on long-term evolution (LTE) technology. The financial terms of the supplier contracts were not disclosed.

The new agreements with Alcatel-Lucent and Ericsson, which build on earlier relationships with AT&T, are expected to enable the wireless carrier to take full advantage of compatibility between the suppliers' existing 3G equipment and forthcoming LTE upgrades, AT&T Operations CEO John Stankey said Wednesday.

"AT&T has a key advantage in that LTE is an evolution of the existing GSM family of technologies that powers our network and the vast majority of the world's global wireless infrastructure today," Stankey said. "As some competitors move away from their existing investment in niche 3G platforms, we are able to efficiently and quickly move toward LTE while enhancing our existing 3G performance and providing access to a strong ecosystem of customer devices."

An Important Step Forward

The selection of Alcatel-Lucent and Ericsson is an important step forward in AT&T's ongoing mobile broadband strategy, Stankey said. LTE field trials are slated to begin later this year, with the first commercial deployments of the equipment at cell sites across AT&T's network in 2011.

AT&T is following in the footstep of rival Verizon Wireless, which likewise tapped Alcatel-Lucent and Ericsson a year ago to serve as the primary vendors of LTE infrastructure equipment for the carrier's 4G deployments. Verizon plans to deploy LTE commercially beginning this year, thus giving it a potential head start over rival AT&T.

However, Verizon's apparent timing advantage may be limited to nothing more than "some marketing hype," noted Gartner Research Vice President Phil Redman. "National coverage is not promised by year-end 2010," which means "it will be even less available than 3G," he said.

Moreover, LTE-compatible phones will not become available this year and maybe even next year, Redman observed. "The volumes aren't there yet to get the manufacturers to commit to anything before 2012," Redman explained. So LTE will basically be limited initially to "PC cards and notebooks that will also roam onto 2G/3G networks where coverage allows." (continued...)
