Dell Wireless 5811E M.2 WWAN card

This Dell Wireless 5811E DW5811e card adds 4G LTE mobile broadband to compatible Dell laptops through an M.2 slot. It is intended for users of the listed Latitude and Precision models who need cellular connectivity without external dongles.

Sustained cellular connectivity

The card maintains a mobile broadband link as long as the host laptop provides power to the M.2 slot and a valid SIM is inserted. Performance under continuous use depends on the laptop's thermal design and the cellular network conditions at the location.

Check M.2 slot and SIM support

Verify that your laptop appears in the compatible model list and that its M.2 keying matches the card. Confirm the chassis includes a SIM-card slot or tray and that antennas are routed to the WWAN connector area before ordering.

Questions about this item

How much power does the DW5811e draw when the laptop runs all day on LTE?

The card is powered directly from the M.2 slot and draws only milliwatts when active, so it has no measurable effect on battery life during all-day use.

Which antenna cables must already be present in the laptop for the DW5811e to work?

Two U.FL coaxial leads — main and diversity — routed to the display lid are required; the card will not connect without them.

Will the DW5811e function in a Precision 7510 that originally shipped with a different WWAN card?

Yes, the 7510 is on the validated list and the card uses the same M.2 keying and antenna connectors as the factory option.
