Lenovo Fibocom L860-GL-16 4G LTE Wireless Cellular Modem

The Lenovo 4XC1K20992 is a modem that installs inside select ThinkPad laptops and delivers 4G LTE Cat16 mobile broadband without the need for external dongles or hotspots. Using an M.2 PCIe Gen2 connection, the module links directly to your system and taps into cellular networks for download speeds that can reach 1 Gbps and upload speeds up to 150 Mbps.

Because it sits inside the laptop, the modem draws its power and antenna lines from the system, keeping your workspace clear of cables while maintaining a reliable link on the move. Receive diversity technology helps the modem hold a stronger signal in areas where coverage fluctuates, so video calls, cloud applications, and large file transfers stay stable during commutes, client visits, or field assignments.

Professionals who rely on uninterrupted connectivity—such as consultants, journalists, field engineers, or anyone who works in transit—will appreciate the ability to open the lid and connect instantly. For IT teams, integration is straightforward thanks to the standard M.2 form factor and Lenovo’s firmware support, making it easy to outfit a fleet of laptops with secure, always-on broadband.
