1.1 Overview
The LARA-R2 series comprises LTE Cat 1 / 2G multi-mode modules supporting up to three LTE bands and up to
two 2G GSM/(E)GPRS bands for voice and/or data transmission in the very small LARA LGA form-factor (26.0 x
24.0 mm), easy to integrate in compact designs:
LARA-R204 is designed primarily for operation in North America (on Verizon network)
LARA-R211 is designed primarily for operation in Europe, Asia and other countries
LARA-R2 series 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 LTE high data rate 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 2G (CSFB) for applications that
require voice, such as security and surveillance systems.
