AUSTIN, TX--(Marketwired - Dec 13, 2013) - VoLTE, or Voice over LTE, is very important to mobile operators because this technology enables them to eventually terminate their legacy, circuit-switched voice 2G/3G network infrastructure in favor of consolidating voice traffic on the LTE network platform. Gradually, VoLTE will allow many operators to refarm spectrum away from 2G/3G to LTE, which will significantly lower voice infrastructure costs.

Several major U.S. mobile operators will likely make VoLTE commercially available on a wide basis in the second half of 2014. Until that time operators will continue testing with select users, resolving significant technical issues, and finalizing their deployment strategy. Once VoLTE is widely deployed, iGR expects the number of VoLTE subscribers to grow significantly -- at a CAGR of 187 percent between 2012 and 2017.

"VoLTE promises to energize both mobile operators and vendors," said Iain Gillott, president and founder of iGR, a market research consultancy focused on the wireless and mobile industry. "Consumers will benefit from the many new multimedia products and services that mobile operators will be able to offer as they transition from legacy voice solutions to the new platform."
