Nokia Siemens Networks gets technology deal from KDDI in Japan

Network equipment vendor Nokia Siemens Networks (NOK, SI) said Thursday it has been chosen to implement technology that enables two types of radio communication technology to work together in KDDI Corp’s (9433.TO) network in Japan.

MAIN FACTS:

-Implementing its Circuit Switched Fallback (CSFB) technology to enable Code Division Multiple Access (“CDMA”) and Long Term Evolution (“LTE”) technologies to work together in KDDI’s network in Japan.

-The deployment will allow KDDI to use its existing CDMA network to continue delivering high-quality voice services while maximizing the efficiency of its newly deployed LTE network.

-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. The operator will be able to maximize the effectiveness of its LTE network bandwidth delivering high-speed data services, while high-quality voice services are carried on the CDMA 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.
