Nokia Siemens Networks Deploying LTE Overlay on CDMA Network in Japan
Published on:
Nokia Siemens Networks says that it is implementing its Circuit Switched Fallback (CSFB) technology to enable CDMA and LTE technologies to work together in KDDI's network in Japan.
Nokia Siemens Networks provided the CDMA network, and is supplying and deploying KDDI's LTE radio network.
KDDI expects to launch LTE services by the end of 2012.
"CDMA is recognized for its high voice quality and high call capacity," said Scott Mottonen, head of the CDMA/LTE business line at Nokia Siemens Networks. "Until LTE technology matures and Voice over LTE (VoLTE) has been optimized, CDMA will fully meet subscribers' expectations while increasing KDDI's return on network investment."
Nokia Siemens Networks' CDMA-LTE CSFB solution is implemented via software on the existing CDMA 1X system, which interfaces with KDDI's LTE network.
Trials of end-to-end CSFB have already been successfully conducted and the nationwide deployment will be completed by mid 2012. This ensures readiness of end-to-end CSFB functionality in anticipation of KDDI's commercial LTE network launch later in 2012.
