T7211 cellular system solution

Best-in-class complete solution for TD-HSDPA/EDGE with dual-mode automatic handover for multimedia-rich feature phones

The T7211 offers all the qualities of the T7210 with a smaller PCB footprint, thanks to the repacking of some of the components. This dual-mode TD-HSDPA/EDGE solution brings 3G functionality to the China market. It is a state-of-the-art design that offers best-in-class multimedia applications, including video and connectivity. It places our market-proven EDGE functionality alongside type-approved, field-tested TD-HSDPA capability developed by our affiliate T3G Technologies. The solution is capable of receiving data at the industry’s highest downlink speed, yet offers ultra-low power consumption. It is provided in a feature phone reference design that provides a complete solution for multimedia-rich feature phones.

The TD-HSPA modem is based on ST-Ericsson's embedded vector processor (EVP) which allows full flexibility and fast time-to-market. Read more about our latest EVP VD32041 by clicking here.
