In spite of having only launched its LTE network a few weeks ago, AT&T is already looking forward to the deployment of even faster networking technology. AT&T Labs head Krish Prabhu has expressed his company's intention to deploy LTE-Advanced in 2013, which keeps broadly in step with Sprint's plans to roll out the same connectivity in the first half of that year. Notably, there's no word yet about when or if AT&T will offer Voice over LTE (VoLTE), which Sprint includes among its 1H 2013 plans, but at least we can be assured that Ralph de la Vega's team is working to an aggressive roadmap. LTE-Advanced should do pretty much what its name suggests in expanding capacity for carriers and raising the speed ceiling for mobile broadband users.
