What Next For VoLGA?

Operators are getting ready for LTE deployments in second half of 2010. However data only deployment is initially expected, followed by voice later. So how does operators are planning to launch voice services - 3GPP CSFB or IMS based or VoLGA ?

Last year there were discussions all around about inability of 3GPP LTE to handle voice from day 1. Kineto Wireless came forward with VoLGA. The VoLGA (Voice over LTE via Generic Access) Forum was initiated last year to promote an approach for extending traditional GSM and UMTS circuit-switched services over LTE access networks. It was an evolution from UMA/GAN but for LTE.

VoLGA claimed to solve voice problem, as operators around the world would adopt IMS voice on different timelines.

3GPP backers came back strongly and major mobile and converged operators such as AT&T, Verizon, France and Telecom/Orange along with powerful wireless equipment vendors such as Ericsson and Nokia-Siemens announced (November 2009) their plan to follow the IMS-based approach for delivery of voice and messaging services over Long Term Evolution (LTE) broadband mobile radio access.
