BARCELONA, Spain, Feb. 25, 2013 /PRNewswire-FirstCall/ -- Qualcomm Incorporated (NASDAQ: QCOM) today announced that its wholly-owned subsidiary, Qualcomm Technologies, Inc., in conjunction with Sierra Wireless and Ericsson, has successfully demonstrated LTE carrier aggregation and Category 4 data rates. LTE carrier aggregation is an important new technology that combines radio channels within and across bands to increase user data rates, reduce latency and enable LTE Category 4 downlink throughput speeds of up to 150Mbps for operators without 20MHz of continuous spectrum. The demonstration, powered by the third-generation Qualcomm Gobi 4G LTE MDM9225™ chipset -- the first in the industry to support LTE carrier aggregation -- Sierra Wireless' AirCard mobile hotspot and Ericsson network infrastructure will be displayed at the Qualcomm and Ericsson booths at Mobile World Congress in Barcelona. "4G LTE networks are being deployed around the world and across a wide range of spectrum holdings -- more than 20 frequency bands and counting. The ability for multimode, multiband 3G/4G LTE mobile devices to connect across two or more LTE bands will be an important part of providing the best possible mobile data experience to consumers," said Cristiano Amon, executive vice president of Qualcomm Technologies and co-president, Qualcomm Mobile and Computing. "Qualcomm is committed to the successful deployment of 4G LTE networks worldwide. The milestone we have achieved with Sierra Wireless and Ericsson is a key step towards making LTE carrier aggregation technology a commercial reality." The Qualcomm Gobi MDM9x25 chipset, manufactured using a 28nm process, also is the first in the industry to support 3GPP Release 10 multicarrier HSPA+ and LTE Advanced. It features significant improvements in performance and power consumption from previous generations. The chipset occupies a smaller design footprint and features significant RF enhancements with an industry-leading combination of carrier aggregation, extensive 2G/3G/4G frequency band support, superior performance and a small PCB footprint with low power consumption.
