AT&T extends VoLTE to new markets

11 Dec 2014

AT&T Mobility has introduced voice-over-Long Term Evolution (VoLTE) and HD Voice technology in select areas of the District of Columbia (DoC), Georgia, Illinois, Indiana, Maryland, Michigan, Minnesota, Nevada, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Texas, Utah, Virginia, Washington and Wisconsin. The carrier’s first VoLTE deployments occurred in Illinois, Indiana, Minnesota and Wisconsin in May this year.

In addition, as reported by TeleGeography’s CommsUpdate last month, AT&T and rival Verizon Wireless have agreed to ensure that VoLTE calls made by customers using the carriers’ respective networks can interconnect with one another. Engineers from both companies are working through a full set of requirements, starting with extensive lab testing and then moving on to field trials. The cellular duo hopes to enable VoLTE-to-VoLTE connections in 2015.
