Lenovo 4XC1U10820 ThinkPad Rolling Wireless RW350 Sub6 5G WWAN Module for P16 G3 content_copy

The Lenovo 4XC1U10820 is an integrated WWAN module (Wireless Wide Area Network) designed for use in laptops, specifically developed for the ThinkPad P16 Gen 3 model. It serves as a wireless network card for mobile data connection via cellular networks and enables the use of 4G networks. The component connects via an M.2 host interface and uses PCI Express version 3.0 as the interface to the system. The maximum data transfer rate is 4670 Mbit/s in the downlink, ensuring fast and reliable connectivity for mobile applications. The output voltage is 3.3 V, which is standard for power supply within laptops.

Applications
This module is primarily designed for mobile work environments where a stable internet connection is required independently of fixed network infrastructures. It is particularly suitable for users of the ThinkPad P16 Gen 3 who require data access, email, cloud services, or video conferencing while on the move. Certification according to GCF, PTCRB, CCC, CTA, SRRC, CE, IC, FCC, CBRS, JA
TE, TELEC, and RCM ensures compliance with international standards for radio devices and network components.

Functions and Features in Detail
The module supports 4G mobile network generation and offers high data rates suitable for applications requiring high bandwidth. The Dual SIM Single Active (DSSA) function allows the use of two SIM cards, with only one active at a time, increasing flexibility in network selection. Receive diversity improves signal quality and network stability, especially in areas with weak reception. Compatibility is limited to the ThinkPad P16 Gen 3, ensuring direct integration into the notebook system.

Technology Explained Simply
WWAN technology enables wireless communication over long distances, similar to a mobile phone, but for use in computers. The M.2 interface is a standard form factor for internal modules, enabling a compact design. The PCIe 3.0 interface ensures fast data transfer between the module and the main system. The operating temperature range of -10 °C to 55 °C and relative humidity of 5 % to 95 % during operation demonstrate the module’s robustness under various environmental conditions. Dimensions are 52 mm (width) × 30 mm (depth) × 2.3 mm (height), and weight is 65 g.

Compatibility and Accessories
The module is exclusively intended for use in the ThinkPad P16 Gen 3. No additional accessories or adapters are required, as it integrates directly into the notebook. Compatibility with Windows 11 Pro is guaranteed, defining the system requirements for operation.

Installation and Mounting
