Huawei completed an end-to-end voice interoperability test for LTE TDD to CDMA.
The test used the Qualcomm Snapdragon 400 (8X30) processor and its solutions for CSFB (Circuit Switched Fallback) and eCSFB (Enhanced CSFB). Huawei said CSFB and eCSFB voice solutions will play significant roles during the initial deployment of LTE networks.
Kevin Wu, President for CDMA/LTE Wireless Networks at Huawei, said, “This successful test is a milestone for the commercialization of LTE voice technologies. It gives CDMA operators more choices for smoothly evolving to a wholly integrated LTE system, and reaffirms Huawei’s commitment to protect existing investments and improving the operational efficiency of multi-mode and multi-frequency networks.”
