The Lenovo 4XC1Q24438 is an integrated WWAN module in M.2 form factor, specifically developed for integration into ThinkPad laptops. It serves as a mobile broadband modem and enables wireless network connection via 4G-LTE networks. The module is based on the Quectel EM061K-GL chipset and supports LTE-Advanced technology of category 6. It is designed for use in professional environments where a reliable and fast mobile internet connection is required, for example, in mobile workstations, field service, or vehicles.

Applications

The module is primarily intended for use in ThinkPad notebooks that feature a corresponding M.2 slot for WWAN modules. It is suitable for users who require a constant network connection independent of fixed WLAN infrastructures. The worldwide coverage of LTE-A and UMTS/HSPA+ networks makes it a flexible solution for international business travel. Support for Windows 11 ensures compatibility with current operating systems.

Functions and Features in Detail

The module offers a theoretical maximum data transfer rate of up to 300 Mbit/s in the downlink and 50 Mbit/s in the uplink, sufficient for smooth video and data transmission. The USB 2.0 interface enables communication with the host system. The integrated eSIM function (optional) allows flexible network configuration without a physical SIM card. The module is designed for faster, more precise, and more reliable positioning, which is particularly beneficial for applications with GPS integration.

Technology Explained Simply

The module uses the M.2 standard, which provides a compact and standardized form for internal components. The WWAN interface (Wireless Wide Area Network) enables connection to mobile networks. The LTE-Advanced technology of category 6 offers higher bandwidth and reliability compared to older LTE generations. The USB 2.0 interface ensures stable data transfer between the module and the laptop. The integrated eSIM (optional) enables flexible network configuration without a physical SIM card, simplifying maintenance and configuration.

Compatibility and Accessories

The module is specifically developed for ThinkPad laptops and requires a corresponding M.2 slot for WWAN modules. It is compatible with Windows 11. Worldwide certification (including CE, FCC, IC, RCM, PTCRB, GCF, UKCA, KC, JA
TE, TELEC, NBTC, IMDA, ICASA) ensures usability in various countries.

Installation and Mounting

The module is installed as an integrated component inside the laptop. Installation is performed by inserting it into the appropriate M.2 slot of the laptop. No additional software or driver installation is required, as the module is natively supported by Windows 11. Installation does not require any special tools or additional components.

Operational Advantages

The module provides a reliable mobile internet connection with high data rates sufficient for modern applications. The worldwide network coverage enables use in various regions. The integrated eSIM function (optional) simplifies network configuration. The high operating temperature of up to 75 °C and storage temperature up to 90 °C make the module suitable for demanding environments. The relative humidity of 5 to 95 % during operation demonstrates the module’s robustness under various climatic conditions.

The warranty period is 1 year. The module dimensions are 30 mm (depth) × 42 mm (width) × 2.3 mm (height), and the weight is 6.2 g. Packaging data (53 mm × 144 mm × 177 mm, package weight 30 g) are relevant for shipping and storage, but not for the module’s operation itself.
