Lenovo 4XC1K04678 netwerkkaart intern WWAN 1000 Mbit/s

ThinkPad Fibocom L860-GL-16 XMM7560 CAT16 4G PCIe M.2 3042 WWAN Module (Lenovo 4XC1K04678) is an internal WWAN network card designed to add cellular connectivity to compatible laptops. The module uses an M.2 PCIe Gen2 3042 form factor interface and supports receive diversity to improve signal reliability. It provides high-speed 4G LTE CAT16 data transfer with theoretical downlink speeds up to 1 Gbit/s and uplink speeds up to 150 Mbit/s, making it suitable for mobile data access and on-the-go connectivity.

Advantages

The WWAN module integrates with Lenovo ThinkPad systems and other compatible devices via the M.2 PCIe interface, offering a compact internal solution without external dongles. Receive diversity improves connection stability in varying signal conditions, while CAT16 LTE support delivers high throughput for data-intensive tasks. Its internal M.2 design keeps weight and footprint minimal (approximately 0.0062 kg).

Suitable for

• Mobile professionals who need reliable cellular internet on laptops
• Travelers requiring consistent data access away from Wi‑Fi
• Fieldwork and remote locations where wired networks are unavailable
• Upgrading a compatible laptop to add WWAN capability
