Qualcomm Technologies Inc., a wholly owned subsidiary of Qualcomm Inc., has released a line-up of products and technologies aimed to drive high-performance computing and connectivity to entry-level and mainstream smartphones and tablets. The latest addition to its Qualcomm Snapdragon 200 tier, the Snapdragon 210 processor, will offer integrated multimode 3G/4G LTE and LTE Dual SIM for entry-level smartphones.

QTI also unveiled the company's first LTE-equipped tablet reference design, enabling OEMs and ODMs to create and introduce a class of multimode 3G/4G LTE connected tablets. Initial versions of the tablet reference design will be available with the Snapdragon 410 and 210 processors. Lastly, QTI announced its latest 28nm transceivers that are optimised to support LTE and LTE Advanced devices in the mid and entry tier, as well as its next-generation Qualcomm RF360 front-end solutions that enable device makers to easily customise LTE Advanced products for global or regional band combinations with enhanced performance and power efficiency.

Additional features of the Snapdragon 210 processor include: seamless, advanced LTE connectivity with fully integrated 4G LTE-Advanced Cat 4 carrier aggregation, LTE broadcast and LTE Dual SIM/Dual standby, high-quality yet cost-effective multimedia experiences with Full-HD (1080p) playback with hardware HEVC, enhanced performance and power efficiency in the entry-level tier with quad CPU and Qualcomm Adreno 304 graphics, up to 8MP camera support and enhanced computational camera functionalities such as zero shutter lag, high dynamic range (HDR), autofocus, auto white balance and auto exposure, and Qualcomm Quick Charge 2.0 support, enabling up to 75 per cent faster battery charging than devices without fast-charging technology, said Qualcomm.

Additional features of the Qualcomm Reference Design (QRD) version of the Snapdragon 210 processor, available in both smartphone and tablet configurations, include all of the aforementioned features in the processor as well as advanced connectivity capabilities including integrated 4G LTE-Advanced Cat 4 carrier aggregation, RF transceiver chip WTR2955, and the Qualcomm RF360 front end solution for multiband and multimode support, noted the company.

Additional features of the QRD based on the Snapdragon 410 processor, also available in both smartphone and tablet configurations, include high-performance, low-power consumption mobile computing with quad-core and 64bit capabilities and the latest Android mobile operating system, stunning multimedia and graphics with the Adreno 306 GPU, and seamless communications virtually anytime, anywhere with an integrated 4G LTE World Mode modem with CAT4 speeds of up to 150Mb/s, detailed the company.

Additional features of the 28nm transceivers and Qualcomm RF360 front end solutions include two 28nm transceivers, the WTR4905 and WTR2955, which pair with the Snapdragon 410 and 210 respectively, and are optimised to support LTE and LTE Advanced multimode devices in the mid and entry tier; and Qualcomm RF360 CMOS power amplifier and antenna switch solutions in both integrated and modular architectures designed to address the growing complexity of carrier aggregation and allow device makers to easily customise LTE advanced products for global or regional band combinations with a 30 per cent reduction in footprint, with enhanced performance and power efficiency, over the previous generation.

Also, the transceivers and front end solutions incorporate the next generation Qualcomm RF360 integrated power amplifier and antenna switch, the QFE3320, a configurable carrier aggregation solution that can be optimised for regional band combinations for mid- and entry-tier devices to address the immediate need of the LTE Advanced ecosystem; modular Qualcomm RF360 front end solution based on separate power amplifiers, the QFE3335/3345, and antenna switches, the QFE1035/1045, that add design flexibility and simplify routing for 2x and 3x carrier aggregation to support all 3GPP approved LTE carrier aggregation band combinations that are commercial or soon-to-be launched by operators worldwide in a single SKU; and next generation Qualcomm RF360 antenna matching tuner, the QFE25xx, with higher linearity and enhanced modem control for stronger LTE connections in the presence of physical impediments such as the user's head or hand.

The Snapdragon 210 processor and QRD reference tablet are expected to be available in commercial devices in 1H15. The RF360 front end products are expected to be available in commercial devices in 2H14.
