Lenovo 4XC1Q24434 ThinkPad Quectel RM520N-GL 5G M.2 WWAN module for X1 Carbon Gen 12/T14 Gen 5 content_copy

The Lenovo 4XC1Q24434 is an integrated WWAN module (Wireless Wide Area Network) for laptops, specifically developed for the ThinkPad series X1 Carbon G12, T14 G5, P14s AMD G5, and T14 AMD G5. It serves as a 5G network card and enables mobile data connectivity via various mobile network standards, with communication occurring through an M.2 interface. The module is designed as an internal component module and is integrated into the laptop, with the antenna also placed internally. It supports 5G NR SA and NSA modes as well as older standards such as LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+, HSDPA, HSUPA, and WCDMA, ensuring broad network coverage. The PCI Express M.2 interface technology enables a fast and stable connection to the laptop system. The module is designed for use in laptops and features a compact form factor with dimensions of 52 mm (width) × 30 mm (depth) × 2.3 mm (height) and a weight of 8.7 g.

Applications

The module is designed for mobile work environments where a constant internet connection is required, regardless of the availability of WLAN networks. It is particularly suitable for business travellers, mobile employees, or field personnel working in various regions or on the move. The support for 5G NR enables high data transfer rates and low latency, which is beneficial for applications such as video conferencing, cloud access, or real-time data transmission. Compatibility with the specified ThinkPad models ensures direct integration without additional adapters or configuration steps.

Functions and Features in Detail

The module offers receive diversity, which improves signal quality and network stability, especially in challenging environments or during movement. It supports GNSS functions, enabling use for location services or GPS-based applications. An optional eSIM function is available, allowing flexible and quick network configuration without a physical SIM card. Support for Windows 10 and Windows 11 ensures compatibility with common operating systems in enterprise environments. The module is also designed for operation in a temperature range of -40 °C to 75 °C, enabling use under various climatic conditions. The relative humidity during operation is 5 to 95 %, demonstrating high robustness under different environmental conditions.

Technology Explained Simply

The module uses the M.2 interface, a standard interface for small, high-performance components in notebooks. The WWAN technology enables connection to mobile networks, making the device reachable over the mobile network via the internet. The 5G NR technology (New Radio) is the current standard for mobile networks and offers higher speeds and capacities compared to older technologies like LTE. Receive diversity improves signal quality by combining multiple antenna signals to minimize interference or signal loss. The GNSS function enables the use of satellite navigation systems such as GPS, which is relevant for applications in logistics, navigation, or location tracking.

Compatibility and Accessories

The module is specifically developed for the ThinkPad models X1 Carbon G12, T14 G5, P14s AMD G5, and T14 AMD G5. It is suitable as a replacement or upgrade module for existing systems requiring mobile data connectivity. Compatibility with the specified models ensures direct installation capability without additional modifications. No special accessories are required, as the module is designed as a standard M.2 module.

Installation and Mounting

Installation is performed by inserting the module into the corresponding M.2 slot of the laptop. The exact mounting instructions are described in the respective ThinkPad manual. The module is designed as an integrated component and does not require additional external antennas or connections. Operation begins automatically after installation, once the operating system is started and network settings are configured.

Advantages in Operation

The module provides a reliable and fast mobile internet connection that functions independently of WLAN networks. Support for 5G NR enables high data rates and low latency, which is important for time-critical applications. Receive diversity and GNSS functions enhance functionality and reliability. Compatibility with ThinkPad models ensures easy integration into existing work environments. The robust construction with an operating temperature range of -40 to 75 °C makes the module suitable for use in environments with extreme conditions.
