MetroPCS Schedules VoLTE Transition for Early 2012
MetroPCS today revealed that it plans to begin transitioning its CDMA-based voice traffic to a new voice-over-LTE system starting in the first quarter of 2012. During its recently quarterly earnings call, MetroPCS CEO Roger Linquist said, "We are planning to begin introducing VoLTE-capable handsets early next year to move voice as well as data traffic to our LTE network." MetroPCS is already moving some of its services, notably SMS/MMS, to its LTE infrastructure. Voice calls placed over the LTE network won't be traditional circuit-switched calls, but will instead rely on VoIP. The move is meant to help MetroPCS make more efficient use of its spectrum assets, which lie in the PCS (1900MHz) and AWS (1700MHz) bands.
