Overview
The TOBY-L4 series modules support multi-band LTE-FDD, LTE-TDD, DC-HSPA+, and (E)GPRS radio access
technologies (see Table 1) in the very small TOBY 248-pin LGA form-factor (35.6 x 24.8 mm), which is easy to
integrate in compact designs.
TOBY-L4 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-Advanced carrier aggregation category 6 data rates up to 301.5 Mbit/s (downlink) / 51.0 Mbit/s
(uplink), the modules are ideal for applications requiring the highest data-rates and high-speed internet access.
Reduced cost variants supporting LTE Cat 4 or LTE Cat 1 will be available for lower speed or “pure” telematics
devices.
TOBY-L4 series include the following LTE Cat 6 modules with 3G and 2G fallback:
TOBY-L4006 modules, mainly designed for operation in North America
TOBY-L4106 modules, mainly designed for operation in Europe
TOBY-L4206 modules, mainly designed for operation in Asia-Pacific and South America
TOBY-L4906 modules, mainly designed for operation in China
TOBY-L4 series modules include the following product versions:
The “00” product versions, integrating the u-blox uCPU on-chip processor to allow customers to run their
dedicated applications on an embedded Linux distribution based on Yocto, with RIL-Core connectivity APIs
The “50” product versions, which can be controlled by an external application processor through standard
and u-blox proprietary AT commands described in the
u-blox AT Commands Manual
TOBY-L4 series modules are the ideal product for the development of all kinds of automotive devices, such as
smart antennas and in-dash telematics / infotainment devices, supporting a comprehensive set of HW interfaces
(including RGMII/RMII for Ethernet and analog audio) over a very extended temperature range that allow the
establishment of an emergency call up to +95 °C, complemented by a set of state-of-the art security features.
TOBY-L4 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-L4 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.
