SIMCom's LTE Cat 4 module drives remote monitoring, interoperability, and predictive maintenance in e-mobility infrastructure.

SIM7600G-H-PCIE: Engineered for Demanding Environments and Global Deployments

The SIM7600G-H-PCIE series module, part of SIMCom's established SIM7600X-H-PCIE series, is a robust LTE Cat 4 communication solution tailored for demanding industrial applications such as EV charging stations. It offers download speeds up to 150 Mbps and upload speeds up to 50 Mbps, while supporting fallback connectivity modes like UMTS/HSPA+ and GSM/EDGE to ensure continuous network coverage.

The module also carries certifications from leading operators like AT&T, Verizon, T- Mobile, Deutsche Telekom, Orange, and Telstra, as well as regulatory approvals including CE, FCC, IC, GCF, and PTCRB, streamlining global deployment and compliance.

Designed for Integration: Compact Form Factor with Extensive Interfaces

The SIM7600G-H-PCIE features a Mini PCIe form factor, making it suitable for customer integration. With compact dimensions (50.8*31*5.35 mm) and a typical power supply of 3.0-3.6 V, it integrates easily into EV charger controllers, industrial gateways, or embedded supervisory systems.

To ensure broad platform compatibility, the module includes USB drivers for Windows, Linux, and Android, and RIL support for Android versions 5.0 to 12. It also offers an extensive set of industrial interfaces, including USB, UART, GPIO which is suitable for main IoT applications.

Advanced Features for Secure Connectivity and Remote Management

Beyond stable connectivity, the SIM7600G-H-PCIE includes advanced features essential for industrial IoT. It supports key networking protocols such as TCP/IP/IPV4/IPV6/Multi-PDP/FTP/FTPS/HTTP/HTTPS/DNS, ensuring safe communication with cloud services and backend platforms.

The module supports remote firmware updates via FOTA or USB, a critical feature for distributed deployments where physical intervention is costly or impractical. Additional capabilities such as VoLTE, USB Audio, and audio playback support make it adaptable to solutions involving user interaction or voice communication.

Moreover, it optional integrates a high-precision multi-constellation GNSS receiver support, compatible with GPS, GLONASS, BeiDou, and Galileo, making it ideal for mobile charging units or applications requiring accurate geolocation.

Applications in EV Charging Infrastructure

The SIM7600G-H-PCIE is particularly well-suited for a wide range of applications in electric vehicle charging infrastructure, where robust, reliable, and easily integrable connectivity is essential for distributed systems. Key use cases include:

• Remote management of charging stations (CSMS and backend)

The module enables persistent connections between the local controller of the charging station and the central Charge Station Management System (CSMS). This allows real- time operational data collection — such as availability status, energy consumption, fault reporting, and session usage — critical for performance monitoring, billing, and remote diagnostics. Thanks to support for multiple networking protocols, the SIM7600G-H- PCIE can be seamlessly integrated into OCPP-based systems, the industry standard for EV charging.

• Access control, authentication, and payments

LTE connectivity allows stations to authenticate users via mobile apps, RFID cards, or roaming platforms. The secure exchange of tokens and credentials is enabled by TLS encryption, ensuring transaction integrity and interoperability with e-mobility operators, even in locations without fiber or Wi-Fi.

• Predictive maintenance and asset management

The module enables periodic or on-demand transmission of key sensor data — current, voltage, system temperature, fault status — facilitating the implementation of predictive maintenance algorithms and real-time alerting. It can also send event logs, usage statistics, and environmental parameters for advanced analytics or compliance reporting.

• Geolocation and deployment logistics

With its integrated optional GNSS receiver, the SIM7600G-H-PCIE delivers high-accuracy positioning, making it ideal for mobile or temporary EV charging stations used at events, in emergencies, or for trial deployments. It also supports RTLS (Real-Time Location Systems) for tracking assets during transport or relocation.

• Remote firmware updates (FOTA)

Built-in FOTA capabilities allow manufacturers and operators to update the software of the local controller or embedded system over-the-air, reducing maintenance costs and enabling support for new features or protocol updates such as OCPP revisions.

• Redundancy and fallback connectivity

In critical installations, the SIM7600G-H-PCIE can serve as a redundant communication channel, ensuring continuity of service if the primary fiber or Wi-Fi connection fails — especially important for fast or ultra-fast charging stations where uptime is essential.

A Strategic Solution for the New Energy Infrastructure

In a rapidly evolving electromobility sector, where charging stations must be smarter, more autonomous, and always connected, the SIM7600G-H-PCIE emerges as a strategic enabler. With its combination of powerful LTE connectivity, flexible integration options, and industrial- grade reliability, this module accelerates IoT development, ensures compliance across regions, and supports the operational continuity of mission-critical EV infrastructure.

SIMCom's SIM7600G-H-PCIE is not just a communication module — it is a technological enabler for the future of sustainable mobility.
