The LE920A4 LTE Module has been specifically developed for Automotive applications. It supports the latest approved eCall and ERA GLONASS standards for protocols and in-band modem. Each of the product variants supports voice over LTE (VoLTE) with circuit-switch fallback (CSFB) to 3G or 2G aligned with regional requirements. The module delivers LTE data rates of 150 Mbps downlink and 50Mbps uplink with fallback support to HSPA+ at 42Mbps down and 5.76Mbps up. Additional fallback to UMTS, EDGE or GPRS gives the module the widest possible combination of connection technologies to ensure the customer application will stay connected, particularly in life-critical situations.

The module&rsquos internal application processor is a 1.2GHz Cortex A7 CPU rated at 2,300 Dhrystone MIPS running embedded Linux Operating System. The Telit AppZone Application Development Environment (ADE), available for use with the LE920A4, helps automotive OEMs and tier-one suppliers develop and/or port application software to the module quickly and easily, enabling reuse of their own libraries along with the extensive resources available for development in the Linux environment.

The module&rsquos audio interface can include an internal codec for direct analog connection and eSIM support is available, tailored to individual requirements of the OEM or tier one integrator. An efficient firmware over the air (FOTA) solution framework allows the automaker to implement revision control and update of all module software. Optional hardware features include dead-reckoning location support, serial gigabit media independent interface (SGMII) for Ethernet connectivity to other data appliances in the car and an interface to connect the module directly to an external advanced Wi-Fi integrated circuit.

The LE920A4 is a member of the Telit xE920 automotive IoT module family. Its 34 x 40 mm LGA form factor is delivered in a ruggedized, mechanically robust package with excellent thermal characteristics for effective heat dissipation. With an operating temperature range of -40°C to +85°C, it is suitable for demanding applications and environments in a cost effective, high-reliability mounting solution. xE920 modules are designed and manufactured according to ISO TS16949 processes to ensure quality and compliance with automotive OEM and tier-one supply chains requiring this certification.
