MADRID, Spain — Qualcomm Incorporated (Nasdaq: QCOM), Telefónica Espa?a and Huawei Technologies announced the completion of a 3G UMTS and HSDPA field trial using 900 MHz spectrum in Talarrubias, located in the Extremadura region of Spain.

The trial results validated that UMTS can co-exist with GSM at 900 MHz. Furthermore, it was proven that the propagation advantage of 900 MHz may be used to extend the significant spectral efficiency gains of UMTS for voice and data coverage relative to 2100 MHz that is currently used in European 3G markets.

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

Under Telefónica’s guidance, Qualcomm’s Engineering Services Group (ESG) led the execution of the UMTS 900 technology trial that involved Huawei UMTS/HSDPA 900 MHz base station products and Qualcomm’s Mobile Station Modem™ (MSM™) chipset-based terminals.

“UMTS 900 enables far superior signal penetration for in-building coverage than at 2100 MHz, which will improve the user experience significantly,” said Mr. Yu Chengdong, wireless president, Huawei Technologies. “The band also allows for far fewer cell sites, which reduces network build-out costs to reach the desired coverage and quality in all areas. The trial demonstrates that infrastructure solutions are mature for commercial deployment.”
