Voice call performance measurements in 2G, 3G and VoLTE in LTE networks
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. VoLTE, on the other hand, is a fully packet switched technology which uses Voice over IP (VoIP) technologies.
