Qualcomm confirmed that its next generation Gobi modem chipsets, the MDM8225, MDM9225 and MDM9625 chipsets, will begin sampling in Q4 2012 and will be the first to support both HSPA+ Release 10 and the next-generation of the LTE mobile broadband standard, LTE Advanced.
The MDM9225 and MDM9625 chipsets, which represent Qualcomm’s third generation LTE modem chipsets, will also support LTE carrier aggregation and LTE Category 4 with data rates of up to 150 Mbps. These chipsets will be implemented in a 28nm manufacturing process, enabling significant improvements in performance and power consumption from previous generations for smartphones, tablets, ultra-portable notebooks, portable hotspots, dongles and CPE. Qualcomm noted that these designs integrate 7 different radio access modes on a single baseband chip: cdma2000 (1X, DO), GSM/EDGE, UMTS (WCDMA, TD-SCDMA) and LTE (both LTE-FDD and LTE-TDD).
In addition to supporting both LTE Advanced (LTE Release 10) and HSPA+ Release 10 (including 84 Mbps dual carrier HSDPA), they are backward compatible with other standards including EV-DO Advanced, TD-SCDMA and GSM.
“Our newest generation of Gobi modem chipsets will allow mobile device OEMs to design products that can operate on nearly any mobile broadband network worldwide,” said Cristiano Amon, senior vice president of product management, Qualcomm. “In addition to supporting the latest mobile broadband technologies, these chipsets improve over Qualcomm’s previous 7-mode 28nm LTE chipsets (MDM9x15) by offering a reduction in power consumption and overall board area, enabling OEMs to design smaller, sleeker devices with longer battery life.”
LTE carrier aggregation combines multiple radio channels within and across bands to increase user data rates, reduce latency and enable Category 4 capabilities for operators without 20 MHz of continuous spectrum.
The MDM8225 chipset supports UMTS only devices, the MDM9225 chipset supports LTE and UMTS devices and the MDM9625 chipset supports LTE, UMTS and CDMA2000 devices. All three chipsets are expected to begin sampling in Q4 2012.
