3G Americas - This white paper reveals solutions that facilitate a smooth migration for network operators as they deploy LTE.

Ericsson - The GSMA IR.92 voice-over-LTE and GSMA IR.94 IMS conversational video specifications are the preferred industry choices for mass-market voice and video calling services over LTE, satisfying user expectations and providing the most advantageous solutions for operators.

The 3GPP LTE system has been designed to offer significantly higher data rates, higher system throughput, and lower latency for delay critical services.

The expansion and evolution of cellular networks over the past decades has been astounding. Networks initially designed for voice traffic have grown to accommodate increasingly high data-traffic loads. This growth has long relied on a network of macro cells to provide a good balance of wireless coverage and
capacity.

The whitepaper compares wireless Voice calls in LTE networks using Circuit Switched Fallback (CSFB) and  Voice over LTE (VoLTE) – based on actual measurements. Further, the whitepaper compares CSFB and VoLTE to legacy technologies such as 2G and 3G. CSFB provides a mechanism to transfer an initiated voice call to legacy circuit-switched networks.

LTE enables you to redefine the end-user experience with the most advanced packet-based solution in the industry.
