u blox's SARA-U260 dual-band 3G/2G module has achieved 'AT&T network compatible' status, allowing customers to design modems into M2M devices operating over AT&T’s 3G network in the USA. Suitable applications include tracking boxes, usage-based insurance devices, smart metering, wearable electronics and connected fitness watches.

SARA-U260 is a complete 3G/2G voice/data module for applications which still require roaming ability with 2G using AT&T’s 3G network coverage. Full voice and data capability and a full suite of IP protocol stacks are provided by the module. Embedded IP protocols include TCP/IP, UDP/IP, HTTP and FTP. Also integrated is in-band modem support for automotive emergency calls like eCall and ERA/GLONASS. The module consumes as little as 0.9mA in cyclic idle/active mode, making it particularly suitable for battery-powered and handheld devices.

In a 16x26mm2 LGA form factor, the module provides efficient and cost-effective mobile connectivity. To support future-proof 4G LTE designs, the module is pin-compatible with SARA-G3 GSM/GPRS modules and layout-compatible with LISA-U2 (HSPA) and TOBY-L2LTE modules.

All SARA modules are based on u-blox’s 'Nested Design' philosophy and share the same form-factor and footprint, allowing engineers to develop one hardware/software platform to support GSM/GPRS, HSPA or LTE. To match u-blox advanced GNSS positioning capabilities, including indoor positioning, the SARA-U260 features direct A-GPS support for accelerated positioning and u-blox’ CellLocate hybrid positioning technology.

For Europe and Asia, u-blox also offers the pin- and software compatible certified version SARA-U270.

“u-blox is proud that AT&T certified our SARA-U260 module for its network,” said Nikolaos Papadopoulos, President, u-blox America. “Our robust voice and data modules deliver powerful 3G connectivity with 2G fallback in the smallest package on the market, at a price that customers recently paid for a 2G module.”
