SARA-U2 UMTS/HSPA modules provide efficient and costeffective high-speed mobile connectivity in an ultra-small LGA form factor. The SARA-U2 series offers seamless drop-in migration from GSM (SARA-G3 modules) and CDMA (LISA-C modules) as well as easy migration to LTE (TOBY-L modules).

SARA-U2 modules feature HSPA data-rates of 7.2 Mb/s (downlink) and 5.76 Mb/s (uplink). The modules have an extended operating temperature range of –40 to +85 C, low power consumption, and a rich feature set including dualstack IPv4 / IPv6.

The SARA-U2 series is ideal for a wide range of industrial and consumer applications, such as connected navigation systems, mobile-internet devices, security and surveillance systems, eCall, fleet management, metering, anti-theft systems, and other automotive applications.

SARA-U2 modules provide a fully integrated interface to u‑blox satellite positioning chips and modules to support telematics applications.

The SARA-U2 series include variants supporting band combinations for North America and Europe/Africa/Asia. For each combination, a cost-saving UMTS-only variant is available.

An extensive set of national regulatory and operator certificates is available, with additional certifications in progress. RIL software for Android and Embedded Windows is available free of charge. SARA-U2 modules are manufactured in ISO/TS 16949 certified sites. Each module is tested and inspected during production. The modules are qualified according to ISO 16750 – Environmental conditions and electrical testing for electrical and electronic equipment for road vehicles.
