AT&T Mobility is getting close to a "soft launch" of its 3G Microcell product, which will use femtocell technology, according to an Unstrung report citing an anonymous source. The carrier could roll out the femtocell product in Atlanta, San Antonio, Seattle and at least one city in North Carolina, according to the report. An AT&T spokesman told FierceWireless that the carrier is currently conducting "customer trials," and that AT&T would have more to share ahead of a possible commercial launch. Earlier this week at 4G World in Chicago, Kris Rinne, senior vice president of architecture and planning at AT&T, said the company continues to test the technology, but did not offer information on possible commercial deployments. Both Verizon Wireless and Sprint Nextel sell femtocells. Article
