4G LTE Cat 16 WWAN card

The Foxconn DW5821e is a 4G LTE Category 16 WWAN card built on the Qualcomm Snapdragon X20 platform. It connects through a PCIe and USB interface in an M.2 3052 form factor. The card supports LTE FDD and TDD bands plus WCDMA, HSPA+, GSM and multiple GNSS constellations including GPS, GLONASS, Beidou and Galileo.

Buyers needing mobile broadband on a laptop

This card suits technicians upgrading or repairing a compatible laptop that accepts an M.2 3052 WWAN module with PCIe and USB signalling. It is not for systems that only provide a PCIe-only or USB-only M.2 key, nor for desktops lacking the necessary antenna routing and BIOS whitelists.

PCIe plus USB interface on M.2 3052

The single specification that decides compatibility is the dual PCIe and USB interface on the M.2 3052 form factor. Many laptops wire the M.2 slot for only one protocol, so the host must expose both interfaces for the DW5821e to function. Matching the part number HMGJ3 or 0HMGJ3 to the service manual confirms fit.

Questions about this item

What M.2 slot size and keying does my laptop need for this DW5821e WWAN card?

The card uses an M.2 3052 form factor, so the slot must accept 30 mm wide by 52 mm long modules with the appropriate key for WWAN.

Will the Qualcomm Snapdragon X20 modem work with my existing nano-SIM and antenna cables?

Yes, the modem connects through the M.2 interface to the laptop's WWAN antenna leads and a standard nano-SIM socket on the board.

How can I confirm the Cat 16 link is active after installation?

Check the connection manager for a 4G LTE Cat 16 indicator and run a speed test to verify up to 1.2 Gbps downstream throughput.
