MADRID, Spain -- Qualcomm Incorporated(NASDAQ:QCOM), Telefonica Espana and Huawei Technologies today announced thecompletion of a 3G UMTS and HSDPA field trial using 900 MHz spectrum inTalarrubias, located in the Extremadura region of Spain. The trial resultsvalidated that UMTS can co-exist with GSM at 900 MHz. Furthermore, it wasproven that the propagation advantage of 900 MHz may be used to extend thesignificant spectral efficiency gains of UMTS for voice and data coveragerelative to 2100 MHz that is currently used in European 3G markets.

UMTS/HSDPA technology at 900 MHz spectrum makes the delivery of voice andhigh-speed 3G services more cost effective as compared to 2100 MHz becauseat lower frequencies, the propagation advantage allows for a significantincrease in the area covered by a base station. This advantage translates tosignificant cost savings for operators and better in-building coverage toimprove the overall user experience for their customers.

Under Telefonica's guidance, Qualcomm's Engineering Services Group (ESG) ledthe execution of the UMTS 900 technology trial that involved HuaweiUMTS/HSDPA 900 MHz base station products and Qualcomm's Mobile StationModem(TM) (MSM(TM)) chipset-based terminals.

"UMTS 900 enables far superior signal penetration for in-building coveragethan at 2100 MHz, which will improve the user experience significantly,"said Mr. Yu Chengdong, wireless president, Huawei Technologies. "The bandalso allows for far fewer cell sites, which reduces network build-out coststo reach the desired coverage and quality in all areas. The trialdemonstrates that infrastructure solutions are mature for commercialdeployment."

"The European mobile industry stands to benefit significantly from thepotential redeployment of the 900 MHz band for UMTS/HSDPA. Qualcomm isworking with its European partners to drive the development of products andservices in this band at a nascent stage through the leadership of ourdedicated European Engineering Services Group," explained Andrew Gilbert,executive vice president and president of Qualcomm Internet Services,MediaFLO Technologies and Qualcomm Europe.
