Detailed Specifications
Lenovo 4XC1Q24435 ThinkPad high speed wireless network WWAN module
Overview
The Lenovo 4XC1Q24435 is a high-speed wireless wide area network (WWAN) module designed to provide seamless 4G LTE connectivity for compatible ThinkPad laptops. Powered by the Fibocom L860-GL-16 chipset, this module supports LTE Category 16 (Cat16) standards, delivering gigabit-class cellular speeds. It is an essential component for mobile professionals, field engineers, and executive travelers who require secure, "always-on" internet access without relying on potentially unsecure public Wi-Fi networks.
Technically, the module utilizes the M.2 (NGFF) form factor and is optimized for global network compatibility, supporting a wide array of LTE bands across various regions. With Cat16 technology, it is capable of theoretical downlink speeds up to 1Gbps, utilizing advanced features like 4x4 MIMO (Multiple Input Multiple Output) and carrier aggregation. It integrates a GNSS (Global Navigation Satellite System) receiver, supporting GPS, GLONASS, and BeiDou for precise location-based services and asset tracking.
Deployment is intended for ThinkPad systems that are "WWAN Ready" (models featuring pre-installed cellular antennas and a SIM card slot). The module is designed for internal installation and is fully certified for use with major global carriers. It features a low-power architecture to minimize the impact on the laptop's battery life while maintaining a high-bandwidth connection. This hardware is specifically engineered for data-centric mobile productivity and is not intended for use in non-ThinkPad hardware or systems lacking the necessary internal antenna infrastructure.
