Functional description
Overview
The LARA-R2 series comprises LTE Cat 1 / 3G / 2G multi-mode modules in the very small LARA LGA
form-factor (26.0 x 24.0 mm, 100-pin) that are easy to integrate in compact designs.
LARA-R2 series modules support up to four LTE bands, up to two 3G UMTS/HSPA bands and up to
two 2G GSM/(E)GPRS bands for voice and/or data transmission.
LARA modules are form-factor compatible with u-blox SARA, LISA and TOBY cellular module families:
this facilitates easy migration from u-blox GSM/GPRS, CDMA, UMTS/HSPA, and other LTE modules,
maximizes the investments of customers, simplifies logistics, and enables very short time-to-market.
The modules are ideal for applications that are transitioning to LTE from 2G and 3G, due to the long
term availability and scalability of LTE networks.
With a range of interface options and an integrated IP stack, the modules are designed to support a
wide range of data-centric applications. The unique combination of performance and flexibility make
these modules ideally suited for medium speed M2M applications, such as smart energy gateways,
remote access video cameras, digital signage, telehealth and telematics.
LARA-R2 series modules support Voice over LTE (VoLTE) and voice service over 3G or 2G (CSFB) for
applications that require voice, such as security and surveillance systems.
