SARA-R4 (x2B) series
Multi-band LTE-M / NB-IoT and EGPRS modules
Product description
At 16 x 26 mm, the SARA-R4 (x2B) series modules provide an
ultra-compact LTE-M/NB-IoT and EGPRS multi-mode product
in a single hardware design. They have software-based LTE
band configuration, and come in an LGA package for easy
manufacturing.
The SARA-R410M and SARA-R412M variants simplify diverse
deployments worldwide and provide enormous operational
eciencies. Software-based congurability of operator proles
and LTE bands enables a wide range of multi-regional coverage.
The exibility extends further through system selection as
LTE-M, NB-IoT, EGPRS single or preferred modes. Customers
can future-proof their solutions by means of OTA rmware
updates, thanks to the uFOTA client/server solution, which
utilizes LWM2M, a light and compact protocol ideal for IoT
applications. The modules oer low power consumption by
utilizing PSM and eDRX, which extend battery life to up to 10
years. Coverage enhancement reaches deeper into buildings
and basements (and underground with NB1) with up to 15 dB
improved MCL compared to GSM or LTE Cat 1.
With many interface options and an integrated IP stack, the
SARA-R4 modules are targeted to a wide range of data-centric
IoT applications, such as smart metering, smart lighting,
telematics, asset tracking, remote monitoring, alarm panels,
and connected health. The SARA-R4 modules target long life,
low-maintenance, cost-sensitive, lower power consumption,
extended battery life applications.
The SARA form factor follows the u-blox nested design prin-
ciple and is compatible with other u-blox product families,
which facilitates easy migration from 2G, 3G and 4G. This also
maximizes the investments of customers, simplies logistics,
and enables very short time-to-market.
The temperature range of –40 to +85 °C guarantees operation
in harsh environments. The module is manufactured in ISO/TS
16949 certied sites with the highest production standards,
quality and reliability. Each module is fully tested and inspected
during production.
