Overview
The SARA-R4 series comprises LTE Cat M1 / NB1 multi-mode modules in the miniature SARA LGA form-factor
(26.0 x 16.0 mm, 96-pin), that allows an easy integration in compact designs and a seamless drop-in migration
from u-blox cellular module families.
SARA-R4 series modules are form-factor compatible with u-blox LISA, LARA and TOBY cellular module families
and are pin-to-pin compatible with u-blox SARA-N, SARA-G and SARA-U cellular module families. This facilitates
migration from the u-blox NB-IoT, GSM/GPRS, CDMA, UMTS/HSPA and other LTE modules, maximizes customers
investments, simplifies logistics, and enables very short time-to-market.
The modules are ideal for LPWA applications with low to medium data throughput rates, as well as devices that
require long battery lifetimes, such as connected health, smart metering, smart cities and wearables.
SARA-R4 series includes the following modules:
SARA-R404M single-band modules designed primarily to operate in North America on Verizon network
SARA-R410M-01B quad-band modules designed primarily to operate in North America on AT&T network
SARA-R410M-02B multi-band modules, with software-based bands’ configurability for worldwide operation
LTE Cat M1 supports vehicular handover capability and delivers the technology necessary to enable the use of
the modules in applications such as vehicle, asset and people tracking where mobility is a pre-requisite. Other
applications where the module is well suited include and are not limited to: smart home, security systems,
industrial monitoring and control.
SARA-R4 series modules support data communication up to 375 kb/s over an extended operating temperature
range of –40 to +85 °C, with low power consumption, and with coverage enhancement for deeper range into
buildings and basements (and underground with NB1). The modules will also support Voice over LTE Cat M1.
The flexibility extends further through dynamic mode selection as M1-only/preferred or NB1-only/preferred.
