Low power 2G M2M module aims at cost-sensitive applications

January 23, 2014 // By Christoph Hammerschmidt
Wireless modules vendor u-blox addresses cost-sensitive M2M applications with the SARA-G340, a dual-band (900/1800 MHz) GSM/GPRS module in a compact LGA module form factor. The device addresses automotive applications such as fleet management and eCall but also industrial M2M applications like metering, security and payment terminals for deployement in Europe and Asia.

The SARA-G340 voice/data module is the ninth variant of the company's SARA modem series consisting of the SARA-G3 GSM/GPRS and SARA-U2 UMTS/HSPA/GSM/GPRS/EDGE module families. The SARA series includes full-featured and cost-optimized versions to cover a wide range of application requirements. Very low power consumption is a primary feature of the SARA-G3 module series, with a standby current of less than 0.9 mA.

In Europe and Asia, GSM/GPRS is a key and popular technology for connected M2M devices. u-blox has optimized the SARA-G340 for these applications, enabling customers to integrate ’smart' M2M connectivity into their products. At the same time, the company's module compatibility philosophy gives customers a path to the creation of an HSPA version of their products via the SARA-U2 series, the industry’s smallest 3G module.

SARA-G340 provides mobile connectivity in an ultra-small 16 x 26 mm LGA form factor. All 9 SARA cellular GSM and UMTS modules provide seamless pin compatibility with each other. They also provide migration to TOBY LTE modules to support future-proof 4G designs.

The SARA-G340 suits to a wide range of M2M applications requiring GSM/GPRS, voice and/or data, internet suite (embedded TCP/IP, UDP/IP, HTTP and FTP), and in-band modem support for eCall and ERA GLONASS vehicle emergency call applications. Very low power consumption recommends it for portable or battery and solar-powered Machine-to-Machine (M2M) communication applications.
