MWC2011: LTE, HSPA+ modems from ST-Ericsson
ST-Ericsson has launched two modems enabling manufacturers to develop devices that can connect to LTE and HSPA+ networks.
The Thor M7400 platform support the latest LTE and HSPA+ dual-carrier technologies and the Thor M7300 supports HSPA+ capabilities up to 84 Mbps, while preserving backward compatibility to existing 3G/2G networks.
The Thor modems supports up to eight LTE/HSPA/GSM bands, enabling development of smartphones, tablets and many other mobile broadband-enabled devices.
The modems include memory-less technology which is used when combining with an application processor in smartphones.
The Thor M7400 is a two-chip LTE/HSPA+ modem. The two-chip Thor M7300 is for the coming dual carrier volume market for smartphones and tablets.
“Our radio solution supports the regional LTE FDD/TDD bands in use in Asia, Europe and North America, as well as HSPA/EDGE networks worldwide,” says CTO Jörgen Lantto.
The modems are based on a common architecture, enabling ST-Ericsson and its customers to benefit from shorter time-to-market by re-using of modem certification and application processor interfaces across platforms, reducing time-to-market.
The new Thor modems are also pin-to-pin compatible which enables customers to completely reuse their design across the two platforms.
Available for operator testing and integration into devices from Q2 2011, the Thor M7400 modem can connect to 2G, 3G, TD-SCDMA, HSPA, HSPA+ dual carrier and LTE FDD/TDD networks.
It offers peak download speeds of up to 100Mbps in LTE networks. The ThorM7400 supports voice calls via fallback to circuit-switched networks and via the VoLTE (Voice over LTE) standard.
Also available for sampling from Q2 2011, Thor M7300 can connect to HSPA+ networks at peak download speeds up to 84 Mbps.
All of ST-Ericsson’s Thor modems are equipped with communication interfaces, enabling them to be integrated with the ST-Ericsson Nova application processors into complete device platforms, including memory-less modem design when combined with an application processor.
