TOBY-L3 series - System Integration Manual
TSD-19090601 - R13 System Integration Manual Page 7 of 143
1 System description
1.1 Overview
The TOBY-L3 series modules support multi-band LTE-FDD, LTE-TDD, DC-HSPA+, and (E)GPRS radio access
technologies in the very small TOBY 248-pin LGA form-factor (35.6 x 24.8 x 2.6 mm), which is easy to
integrate in compact designs.
TOBY-L3 series modules are form-factor compatible with the other u-blox cellular module families (including
SARA, LISA, LARA, and TOBY form factors): this allows customers to take maximum advantage of their
hardware and software investments, and provides very short time-to-market.
With LTE category 4 data rates up to 150 Mb/s (downlink) / 50 Mb/s (uplink), the modules are ideal for
applications requiring the highest data-rates and high-speed internet access.
TOBY-L3 series modules include the following product versions:
The “1x” product feature versions, or "SMART modem" product feature versions, which allow customers
to run their own dedicated applications on an embedded Linux distribution with libTS library APIs in the
open CPU on-chip processor
The “0x” product feature versions, or "SLIM modem" product feature versions, which can be controlled
by an external application processor through standard TOBY-L3 series AT commands User Manual [2].
TOBY-L3 series modules are the ideal product for the development of all kinds of automotive or industrial
devices, such as smart antennas and in-dash telematics / infotainment devices. This module supports a
comprehensive set of HW interfaces (including SGMII for Ethernet and digital audio) over an extended
temperature range that allows the establishment of an emergency call up to +85 °C, and complemented
by a set of state-of-the art security features.
TOBY-L3 series modules are also the perfect choice for consumer fixed-wireless terminals, mobile routers
and gateways, applications requiring video streaming and many other industrial (M2M) applications.
TOBY-L3 series modules are manufactured in ISO/TS 16949 certified sites, with the highest production
standards and the highest quality and reliability. Each module is fully tested and inspected during production.
The modules are qualified according to the automotive requirements as for systems installed in vehicles.
