The Lenovo network card with manufacturer number 4XC1Q24437 is an integrated WWAN module in M.2 form factor, specifically designed for use in laptops. It is a 4G LTE-A Cat 16 module based on 3GPP Release 14 technology, enabling a maximum downlink speed of 1.0 Gbit/s and an uplink speed of 150 Mbit/s. The module is intended for use in ThinkPad X1 2-in-1 Gen 9 and P16s Gen 3 and offers worldwide coverage for LTE-A and UMTS/HSPA+ networks. The integrated antenna supports wireless communication, with the host interface implemented via M.2, allowing for compact and efficient integration into mobile devices.

Applications

The module is primarily designed for mobile work environments where a constant, wireless network connection is required. It is suitable for professional users who are on the move and rely on a reliable internet connection, such as in mobile office settings, remote maintenance, or logistics. The support for LTE-A Cat 16 ensures high bandwidth and low latency, which is beneficial for applications such as video conferencing, cloud access, or real-time data transmission. The worldwide network coverage enables use in various countries without additional hardware modifications.

Features and Specifications in Detail

The module includes an integrated antenna for optimal signal transmission. It supports Qualcomm® IZat™ location technology Gen8C Lite, enabling the use of GNSS systems such as GPS, GLONASS, BeiDou, and Galileo. This multi-constellation support increases the accuracy and reliability of positioning, especially in urban environments or poor visibility conditions. The PCIe standard interface ensures stable and fast data transfer between the module and the laptop system.

Technology Explained Simply

The term WWAN (Wireless Wide Area Network) describes the module’s ability to communicate wirelessly over long distances, in contrast to WLAN, which is limited to local networks. The M.2 format is a standard for small, high-performance modules that are directly installed into laptops. The 4G LTE-A Cat 16 technology means the module belongs to the more powerful LTE modules, enabling high data rates. Support for 3GPP Release 14 ensures compatibility with current mobile communication standards. The integrated antenna reduces the need for external antennas and contributes to a compact design.

Compatibility and Accessories

The module is specifically developed for the ThinkPad X1 2-in-1 Gen 9 and P16s Gen 3 models. It is designed for use with Windows 10 and Windows 11 operating systems. Certifications include CE, FCC, IC, RCM, PTCRB, GCF, KC, JA
TE, TELEC, NBTC, IMDA, and ICASA, confirming compliance with regional and international regulations for radio equipment.

Installation and Mounting

The module is designed as an internal component and is directly integrated into the laptop. Installation requires opening the device and inserting the module into the corresponding M.2 slot. Physical dimensions are 30 mm (depth) × 42 mm (width) × 2.3 mm (height), allowing for compact placement. The weight is 6.8 g.

Operational Advantages

The high data rate and worldwide network coverage enable flexible use in various regions. Multi-constellation support for GNSS systems increases positioning accuracy. The integrated antenna and compact design reduce the need for additional hardware. Support for Windows 10 and 11 ensures broad compatibility with common operating systems. The operating temperature range of -25 °C to 75 °C and storage temperature range of -40 °C to 90 °C make the module suitable for demanding environments. Relative humidity during operation is 5 to 95 %, allowing use in various climatic conditions. The warranty period is 1 year.
